Version 1.8
Version 1.8.0-alpha05
October 30, 2024
androidx.compose.foundation:foundation-*:1.8.0-alpha05
is released. Version 1.8.0-alpha05 contains these commits.
New Features
- Support for auto-sizing text. Pass an
AutoSize
instance (e.g.AutoSize.StepBased
) to your favorite text composable (likeBasicText
) and see your text size adapt to the available space! (Ice7e0, b/139320827) - Adds
OverscrollFactory
andLocalOverscrollFactory
APIs to allow configuring overscroll within a hierarchy. The value provided throughLocalOverscrollFactory
will be used by default to create anOverscrollEffect
. To create and remember an effect from the current provided factory, userememberOverscrollEffect()
. (I51ca4, b/255554340)
API Changes
- Introduce
CompositionLocal
that can be used to modify the hue of Autofill's successful filling highlight. (I32092) - Removed
ScrollableDefaults.overscrollEffect
- instead you should userememberOverscrollEffect
. This will create an instance of the current overscroll implementation provided withLocalOverscrollFactory
. (I1651a, b/255554340),(b/234451516) - Introduces new
AutofillManager
interface that can be used to fine-tune users' Autofill journey and aisSemanticAutofillEnabled
flag to turn on this new version of Autofill. (I9d484) - Removes
CombinedClickableNode
. This experimental API was temporarily exposed to unblock performance work, but is no longer needed. Instead you should directly useModifier.combinedClickable
as with other modifier APIs. (I4b658) - Adds overloads to
horizontalScroll
,verticalScroll
,LazyColumn
,LazyRow
,LazyHorizontalGrid
,LazyVerticalGrid
,LazyHorizontalStaggeredGrid
,LazyVerticalStaggeredGrid
,HorizontalPager
, andVerticalPager
with support for specifying a customOverscrollEffect
. The providedOverscrollEffect
will receive events, and be rendered within the bounds of these components. Note that drawing the sameOverscrollEffect
twice is unsupported - so you cannot draw the sameOverscrollEffect
provided to one of these components separately withModifier.overscroll
. The use case of drawing the overscroll outside of the bounds of these components will be addressed separately in the future. (I2dc42, b/266550551, b/234274772, b/224572538, b/353805117)
Version 1.8.0-alpha04
October 16, 2024
androidx.compose.foundation:foundation-*:1.8.0-alpha04
is released. Version 1.8.0-alpha04 contains these commits.
API Changes
- Adds
DelegatableNode#onDensityChange
andDelegatableNode#onLayoutDirectionChange
callbacks to allow updating node state when these change. (I04f3e, b/340662451) - Paragraph and
ParagraphIntrinsics
now takes a list of all annotations applied to theAnnotatedString
, previously it only had a list ofSpanStyles
. (I12f80) - Introduced
PointerInputModifierNode#touchBoundsExpansion
, which can be used to enlarge the touch bounds of a single pointer input modifier. (Iccf02, b/335339283)
Bug Fixes
- Fixed a bug where positional thresholds passed to
AnchoredDraggableDefaults.flingBehavior
were not considered correctly in some scenarios. (Ifdf0d, b/367660226) - Introduce a fix for nested scrollables that are removed from the node tree during an ongoing fling. Now these nodes will cancel the fling and correctly send the
onPostFling
event with the remaining velocity. We're also introducing the flagNewNestedScrollFlingDispatchingEnabled
to control the behavior in case of regressions. The flag will be removed before beta. (I05c37, b/371168883) - Fixed a bug where
OverscrollEffects
passed toModifier.anchoredDraggable
would receive 2D deltas instead of 1D. (Ie52c0)
Version 1.8.0-alpha03
October 2, 2024
androidx.compose.foundation:foundation-*:1.8.0-alpha03
is released. Version 1.8.0-alpha03 contains these commits.
API Changes
- Kotlin version update to 1.9 (I1a14c)
- Introduced flag
DraggableAddDownEventFixEnabled
(I848d5) - Introduced a new Semantics Role called Carousel to emulate the list behavior in Pagers for a11y services. (Id354b, b/354109776, b/239672673)
- Removed the implicit
graphicsLayer
modifier fromBasicText
composable. Added experimentalComposeFoundationFlags.RemoveBasicTextGraphicsLayerEnabled
flag to be able to revert to the old behavior. (Ie478d) - Added
Modifier.recalculateWindowInsets()
to allow children in the hierarchy to useinsetsPadding
even when parents aligned them withoutconsumeWindowInsets()
. (I7f9e4)
Bug Fixes
- Implement gesture pick-up in
detectDragGestures
, draggables and scrollables. Now if a child draggable gives up on a gesture, the parent has the opportunity to pick it up. This allows for a more continuous and integrated gesture handling. (Ic88fe) - Update fling cancellation behavior in scrollables. Now if a scrollable flings and hits the bounds it will correctly pass on the fling velocity to the next scrollable in the chain instead of continue to drive the fling. (I9326a)

Bug Fixes
- Fixed a bug causing a rare crash in text fields. (I475c6, b/313010266)
- Removed
ReusableContentHost
at the root of Lazy layout items. This was a potential root cause for “measure called on a deactivated node” crashes. (Id6e60)

September 10, 2024
- No changes to Android artifacts.
-desktop
artifacts were removed and-jvmStubs
and-linuxx64Stubs
artifacts were added. None of these targets are meant to be used, they are placeholders to help Jetbrains Compose efforts.
Version 1.7.0
September 4, 2024
androidx.compose.foundation:foundation-*:1.7.0
is released. Version 1.7.0 contains these commits.
Important changes since 1.6.0
- Performance of
Modifier.clickable
,Modifier.focusable
,Modifier.indication
,Modifier.scrollable
andModifier.draggable
has been significantly improved. As a part of this effort, the following API changes were made in addition to internal changes- Added a new Indication API,
IndicationNodeFactory
. This leads to more performant Indication implementations compared to the previous (now deprecated)rememberUpdatedInstance
API. For migration information, see developer.android.com. clickable
/combinedClickable
/selectable
/toggleable
now accepts a nullableMutableInteractionSource
parameter. If null, and the provided Indication is anIndicationNodeFactory
, the Indication can be lazily created only when needed, which improves performance. If you are not hoisting and using theMutableInteractionSource
, it is recommended to pass null instead of passingremember { MutableInteractionSource() }
.Indication#rememberUpdatedInstance
has been deprecated. It has a high unavoidable performance penalty, and prevents other optimizations. Instead, you should use the newIndicationNodeFactory
API.
- Added a new Indication API,
BasicTextField
using aTextFieldState
is now stable and we advise all call-sites to begin migration fromBasicTextField(value, onValueChange)
toBasicTextField(TextFieldState)
.- The
ClickableText
has been deprecated. To add clickable links to your text, useBasicText
with the newLinkAnnotation
annotation in yourAnnotatedString
.LinkAnnotation
allows for custom styling based on link state (e.g. focused, hovered). - Introducing
ContextualFlowRow
andEnhanced FlowRow/Column
withMaxLines
andOverflow
. We are excited to announce enhancements to the experimentalFlowRow
andFlowColumn
, now featuringmaxLines
and overflow support, alongside the debut ofContextualFlowRow
andContextualFlowColumn
. This update is designed to provide performance optimal components, whereContextualFlow*
is perfect for a large number of items making use of a small maxLines config and dynamic +N see more buttons, andFlowRow
andFlowColumn
is perfect for a small number of items, less than 100 items. Important: To maintain existing behavior inFlowRow
orFlowColumn
where all items are composed regardless of if they fit the cross axis max, set overflow toFlowRowOverflow.Visible
orFlowColumnOverflow.Visible
during initialization. ExploreContextualFlowRowSample
andFlowRowSample
for examples of these new features in action. (Ib9135, b/293577082) - Item appearance and disappearance animation support was added into
LazyColumn
andLazyRow
. Previously it was possible to addModifier.animateItemPlacement()
modifier in order to support placement (reordering) animations. We deprecated this modifier and introduced a new non-experimental modifier calledModifier.animateItem()
which allows you to support all three animation types: appearance (fade in), disappearance (fade out) and reordering. (I2d7f7, b/150812265) - Implemented experimental support for long screenshots in Compose scroll containers using the official Android API (
ScrollCaptureCallback
). NestedScroll
sources Drag and Fling are being replaced byUserInput
andSideEffect
to accommodate for the extended definition of these sources that now include animations (Side Effect) and Mouse Wheel and Keyboard (UserInput
).LazyLayout
prefetch requests can be marked as urgent now, meaning that we expect this item to be needed in the next frame and want to ignore frame budget to make sure to do more work in advance (Id513f)- Support stylus handwriting feature on devices after Android U. (I002e4)
- Various APIs have been promoted to stable
- Pagers, snapping, window insets

API Changes
- Adds an experimental API for configuring prefetch behavior of
LazyGrids
similar to the existing experimental API forLazyLists
. This includes support for prefetching items in nestedLazyGrids
. Similiar toLazyListPrefetchStrategy
, the implementation default is to prefetch the first 2 nested items of each grid, but this can be configured by the newLazyGridPrefetchStrategy(nestedPrefetchItemCount)
andLazyListPrefetchStrategy#onNestedPrefetch
APIs. (I591c4) - Renamed
SemanticsProperties.Editable
toIsEditable
and changesSemanticsPropertyReceiver.editable
to a valisEditable
. The property is now a boolean and always specified by text fields. (I8acd8) - Moved
basicMarquee
default values intoMarqueeDefaults
object. (I12ff6) - Renamed
basicMarquee
delayMillis
parameter torepeatDelayMillis
. (I12ff6) - Update API for styling the links: moved the
TextLinkStyles
to theTextStyle
and removed theTextDefaults
from material (I5477b)
Bug Fixes
- Renamed
LayoutCoordinates.introducesFrameOfReference
toLayoutCoordinates.introducesMotionFrameOfReference
to better reflect its purpose. Renamed related function to calculate coordinates based on that flag. (I3a330) - Removed 'Default' from the
MarqueeDefaults
properties. (I1d8a0) - Removed 'Marquee' from
MarqueeDefaults
properties. (Iad4f4) - Removed
TextLinkStyles
from theTextStyle
class. Instead,TextLinkStyles
is part of theLinkAnntation
constructor and theAnnotatedString.fromHtml
method (I90b2b) - Fixed a bug where Pager would snap when flinging towards a bound while already settled at the bound. (I9f373, b/339171222)
- BTF2 now has correct mouse selection gestures. (Ibe8c6)
External Contribution
- Resubmit 'Make compose/measure time calculation content-type based in prefetch to improve accuracy' (Iea622)
- Make compose/measure time calculation content-type based in prefetch to improve accuracy (Ibccb1)
- Make
WindowInsetsPadding
modifiers available from common source set (I070b2)
Version 1.7.0-beta01
May 14, 2024
androidx.compose.foundation:foundation-*:1.7.0-beta01
is released. Version 1.7.0-beta01 contains these commits.
API Changes
- Added
KeyboardOptions.shouldShowKeyboardOnFocus
property back as deprecated hidden for binary compatibility. (I15cfe) Modifier.anchoredDraggable
now reverses drag deltas by default for components with a Horizontal orientation when used in an RTL layout. (I3c6d9)AnnotatedString.hasEqualsAnnotations
is nowhasEqualAnnotations
. (I685c0)- Updated the API for getting Material themed links in text. Specifically, removed the methods from the
TextDefaults
for constructing themedLinkAnnotations
and parse HTML with themed links. Instead, added aTextLinkStyles
class that allows to style the links as a parameter to the Text composable. (I31b93) - Replaced
onDragStarted
andonDragStopped
with non-suspend callbacks. (I59de8)
Bug Fixes
- Fixed a bug where Pager would crash when the
contentPadding
was bigger than the incoming constraints. Pager now coerces negative values returned fromPageSize
to 0. (Iba5d8, b/314008560)
Version 1.7.0-alpha08
May 1, 2024
androidx.compose.foundation:foundation-*:1.7.0-alpha08
is released. Version 1.7.0-alpha08 contains these commits.
New Features
- Added right-click context menu to
BasicTextField
andSelectionContainer
with items for cut, copy, paste, and select-all actions. (If8c93, Ia2b49, I6f268)
API Changes
LazyLayout
prefetch requests can be marked as urgent now, meaning that we expect this item to be needed in the next frame and want to ignore frame budget to make sure to do more work in advance (Id513f)- Renamed
isPositionedByParentWithDirectManipulation
tointroducesFrameOfReference
. Note that it now has the reverse effect, meaning that by default, mostLayoutCoordinates
introduce a frame of reference, and, only when placed under direct manipulation the property will be false. To query position with only those that introduce a frame of reference, usepositionInLocalFrameOfReference(...)
. OrpositionInLocalLookaheadFrameOfReference
from aLookaheadScope
. (Ifc5f7) - Renamed
onClicked
toonClick
insideLinkInteractionListener
(Iaa35c) - Change action lambda for
getScrollViewportLength
as per API council feedback. (Ibc74a) - Renamed stylus handwriting delegation APIs. (Ica45f, b/327271923)
- Rename
TextInclusionStrategy.isInside
toisIncluded
. MakeParagraph/MultiParagraph#getRangeForRect()
return type non nullable. (I51f26)
Bug Fixes
- Added "Select all" to all text contextual menus in
SelectionContainer
. (Ib750e, b/240143283) - Fixed long screenshot capture for scrolling containers with
reverseScrolling=true
. (I7c59c) - Fixed an issue where
AnchoredDraggableState
'scurrentValue
would change when approaching the state's bounds. (Iea30b, b/333846848)
External Contribution
- Renamed
PrefetchExecutor
->PrefetchScheduler
to better reflect its responsibilities. (Ib9154) - Added support for prefetching items in nested
LazyLists
(e.g. aLazyColumn
that renders nestedLazyRows
). This change is expected to reduce frame drops during scrolling for theseLazyLists
. The implementation default is to prefetch the first 2 nested items, however this behavior can be controlled by the newLazyLayoutPrefetchStrategy(nestedPrefetchItemCount)
andLazyListPrefetchStrategy#onNestedPrefetch
APIs. (I51952)
Version 1.7.0-alpha07
April 17, 2024
androidx.compose.foundation:foundation-*:1.7.0-alpha07
is released. Version 1.7.0-alpha07 contains these commits.
New Features
- Added a
TextDefaults
object that contains methods to construct aLinkAnnotation
and parse HTML-tagged string which applyMaterialTheme
to the links. (I98532, b/139312671) - Item appearance and disappearance animation support was added into
LazyVerticalGrid
andLazyHorizontalGrid
. Previously it was possible to addModifier.animateItemPlacement()
modifier in order to support placement (reordering) animations. We deprecated this modifier and introduced a new non-experimental modifier calledModifier.animateItem()
which allows you to support all three animation types: appearance (fade in), disappearance (fade out) and reordering. (Ib7d12, b/330510929) - Item appearance and disappearance animation support was added into
LazyVerticalStaggeredGrid
andLazyHorizontalStaggeredGrid
. Previously it was possible to addModifier.animateItemPlacement()
modifier in order to support placement (reordering) animations. We deprecated this modifier and introduced a new non-experimental modifier calledModifier.animateItem()
which allows you to support all three animation types: appearance (fade in), disappearance (fade out) and reordering. (I69bc9, b/330511290)
API Changes
- Adds
ContextMenuColors
and the associatedLocalContextMenuTheme
ProvidableCompositionLocal
. The colors of the context menu on text fields and selectable text can be modified by providing the composition local. (Ifa154) - Text links got pressed state styling option in addition to normal styling, hovered and focused. (I5f864, b/139312671)
- Introduce
ViewConfiguration.HandwritingGestureLineMargin
for handwriting gestures. Support handwriting gesture forBasicTextField
. (Ie6e13, b/325660505) - Removed
DelegatableNode.scrollIntoView
for the 1.7 release since we didn't have time to finish stabilizing the rest of the related API surface. This function will be re-introduced in 1.8 (I6cf61, b/333421581, b/332900232) - When querying Layout coordinates, you may now use the
excludeDirectManipulationOffset
argument to exclude the offset set by parent Layouts that placed their children usingPlaceable.PlacementScope.withDirectManipulationPlacement
. Likewise, a Layout that changes the position of its children frequently may now place them usingwithDirectManipulationPlacement
(such as Scroll, implemented by default). This helpsapproachLayout
based animations to be more intuitive, having now the opportunity to differentiate what offset to animate, and what to apply directly when deciding to animate their approach. (I60ec7) - Introduce
requestScrollToItem
forLazyStaggeredGrid
. For each measure-pass, the client may now opt-out of maintaining index based on the key by callingrequestScrollToItem
. This does not change existing behavior in any way unlessrequestScrollToItem
is called. (I63983) - Introduce
requestScrollToPage
in Pager. For each measure-pass, the client may now opt-out of maintaining index based on the key by callingrequestScrollToPage
. This does not change existing behavior in any way unlessrequestScrollToPage
is called. (Ic4213) - Introduced
requestScrollToItem
forLazyGrids
. For each measure-pass, the client may now opt-out of maintaining index based on the key by callingrequestScrollToItem
. This does not change existing behavior in any way unlessrequestScrollToItem
is called. (I0a7a0) ClickableText
is marked as deprecated. To add links to the text, create anAnnotatedString
with aLinkAnnotation
corresponding to your link and pass thisAnnotatedString
to theText
composable (I34d4b, b/323346994)UrlAnnotation
is deprecated, useLinkAnnotation.Url
instead. If you're using Material theming, then useTextDefaults
object to create the annotation with Material theming applied to it (I8d180, b/323346545)String.parseAsHtml
renamed toAnnotatedString.Companion.fromHtml
(I43dcd)- Added styling arguments (
linkStyle
,focusedLinkStyle
,hoveredLinkStyle
) and a link interaction listener to theparseAsHtml
method. When parsing the HTML-tagged string with<a>
tags, the method will construct aLinkAnnotation.Url
for each such tag and pass the styling objects and link interaction listener to each annotation. (I7c977) LinkAnnotation
now takes the state-based styling arguments and aLinkInteractionListener
. Add this annotation to theAnnotatedString
to get a hyperlink. By passingfocusedState
and/orhoveredState
you can define the visual configuration for links when they are focused and/or hovered. (I81ce4, b/139312671)- The feature flag for long screenshots has been removed. (I28648, b/329128246)
LazyColumn
will now render sticky headers correctly in long screenshots. (I8d239, b/329296635)- Stabilized majority of the remaining experimental APIs that were introduced with the new
BasicTextField
. (I714e2) - Added
textObfuscationCharacter
parameter toBasicSecureTextField
that controls which character to use while obfuscating the contents. (I0588b) NestedScroll
sources Drag and Fling are being replaced byUserInput
andSideEffect
to accommodate for the extended definition of these sources that now include animations (Side Effect) and Mouse Wheel and Keyboard (UserInput
). (I40579)- Introduce
LocalBringIntoViewSpec
, a platform dependent focus scrolling behavior that is applied at the Scrollable modifier layer. (I27aa5, b/317453911) - Removed
TextFieldCharSequence
.TextFieldBuffer.originalValues
is replaced withTextFieldBuffer.originalText
andTextFieldBuffer.originalSelection
. (I2c7d6) ImeOptions.hintLocales
is no longer nullable. If you want to pass an empty Locale list, please useLocaleList.Empty
. (Ic5bc4)- Renamed
getOffsetFractionForPage
togetOffsetDistanceInPages
. (Ia05e2)
Bug Fixes
- When
InputTransformations
are joined withnext
, theirKeyboardOptions
are now properly merged by individual options using the newKeyboardOptions.merge
method. (Ie5304, b/295951492) AnchoredDraggableState
'stargetValue
now does not consider positional thresholds anymore. It now has an implicit threshold of 50%, meaning that thetargetValue
changes at the midpoint between two anchors. (I82c2c)
External Contribution
- Renamed 2 scroll APIs (I56a75)
Version 1.7.0-alpha06

New Features
- Item appearance and disappearance animation support was added into
LazyColumn
andLazyRow
. Previously it was possible to addModifier.animateItemPlacement()
modifier in order to support placement (reordering) animations. We deprecated this modifier and introduced a new non-experimental modifier calledModifier.animateItem()
which allows you to support all three animation types: appearance (fade in), disappearance (fade out) and reordering. (I2d7f7, b/150812265) - Clients of
LazyColumn/LazyRow
may now opt-out of maintaining an index based on the key for the upcoming measure-pass by calling a non-suspendLazyListState.requestToScroll
. (I98036, b/209652366) - Added
parseAsHtml
method for styled strings: it allows to convert a string marked with HTML tags intoAnnotatedString
. Note that not all tags are supported, for example you won't be able to display bullet lists yet. (I84d3d) - Implemented experimental support for long screenshots in Compose scroll containers using the official Android API (

API Changes
HorizontalPager
,VerticalPager
andPagerState
are promoted to stable. (I67660, b/316966909)- Added
LocalTextLinkStyle
composition local that allows to change the style of the links in Text across the app. If you're using your own theme in the app, you should be setting this composition local according to your theming. When using Material theme the color of the link by default will be set to Material's primary color. (I7eb10) - Introduced
receiveContent
modifier that provides developers with a way to receive rich content in Jetpack Compose. receiveContent
integrates withBasicTextField2
to accept rich content provided by the software keyboard, or via Clipboard paste action. (I81b72)- In this change we're replacing
SnapFlingBehavior
withTargetedFlingBehavior
in pager to unlock other use cases and provide greater flexibility. (I762ea) - In this change we're making Snapping APIs Stable. We're also cleaning up some of the testing code and adding more samples to Snapping. (Id8da9)

Version 1.7.0-alpha01
January 24, 2024
androidx.compose.foundation:foundation-*:1.7.0-alpha01
is released. Version 1.7.0-alpha01 contains these commits.
New Features
- Added a new
Indication API
,IndicationNodeFactory
. This leads to more performantIndication
implementations compared to the previous (now deprecated)rememberUpdatedInstance
API. For migration information, see developer.android.com. clickable / combinedClickable / selectable / toggleable
now accepts a nullableMutableInteractionSource
parameter. If null, and the providedIndication
is anIndicationNodeFactory
, theIndication
can be lazily created only when needed, which improves performance. If you are not hoisting and using theMutableInteractionSource
, it is recommended to pass null.
API Changes
- Introduce
DecayAnimation
inAnchoredDraggable
, this change adds adecayAnimationSpec
parameter toAnchoredDraggable
allowing to use decay animation when settling to one of the anchors. The change also includes renaming the existinganimationSpec
tosnapAnimationSpec
to help understanding the use case of each spec. BasicTextField2
is available for experimental use. It should be roughly at feature parity withBasicTextField
, and behavior should be production-ready. However, the API remains experimental for now. Before stabilizing, it will be renamed toBasicTextField
and moved into the same package.- Introduced the first draft of the
OutputTransformation
API forBasicTextField2
. This API replaces most of the use cases ofVisualTransformation
in the oldBasicTextField
. However it is not complete yet, and some things won't work correctly, but we'd appreciate any feedback on the API usability for your use cases. (aosp/2708848) - Introduced
LinkAnnotation
that allows to add links and clickables into text. Links feature is not complete yet and more API changes are coming. - Introduced
receiveContent
modifier that provides developers with a way to receive rich content in Jetpack Compose. receiveContent
integrates withBasicTextField2
to accept rich content provided by the software keyboard, or via paste from Clipboard.KeyboardOptions.shouldShowKeyboardOnFocus
allows you to disable the default behavior ofBasicTextField
of requesting a software keyboard on focus.TextInputService
andLocalTextInputService
are now deprecated. UsePlatformTextInputModifierNode
to integrate directly with platform IME APIs instead. (aosp/2862698)Indication#rememberUpdatedInstance
has been deprecated. It has a high unavoidable performance penalty, and prevents other optimizations. Instead, you should use the newIndicationNodeFactory
API.
Bug Fixes
BasicTextField
will now pre-validate a small selection of offset mappings whenVisualTransformation
is passed. This helps catch common coding errors that lead to unrecoverable exceptions in later measure or draw passes. By throwing during composition, it is more likely developers will see these errors during development helping avoid production crashes. (I0fd42)VisualTransformation
will not throw if you return an invalid index for an invalid index (b/316401857 )

API Changes
- The
DragAndDropTarget
modifier now takes in the receivingDragAndDropTarget
explicitly and has a lambda to opt into a drag and drop session. There are now two factory functions for aDragAndDropModifierNode
. One for receiving transfers and one for transferring data (I69481) - Updated
maximumFlingVelocity
to be represented as Float. Updated documentation to be more clear about themaximumFlingVelocity
unity. (I8adc7) onDragAndDropStart
in theDragAndDropModifierNode
factory has been renamed toacceptDragAndDropTransfer

test API was introduced to test such nodes. The rest of the test apis will filter out deactivated nodes by default. (I2ef84, b/187188981)clippingEnabled
parameter ofModifier.magnifier
is renamed toclip
.magnifierCenter
parameter ofModifier.magnifier
is made nullable preserving the same default behavior. (I6aa66)Material
SwipeToReveal

andSnapLayoutInfoProviders
. (I153c3) - More modifiers marked as stable. (I56af1, b/298046462)
- Removed
SnapStepSize
fromSnapLayoutInfoProvider
. The calculation should be done using the Layout information and provided through the approach or snapping offsets. (If320c)
Behavior Changes
- Compose now uses non-linear font scaling for better readability and accessibility. When font scale > 100% in system settings, small text will increase in size normally, but already-large text will only increase a little bit. Also, line heights defined in SP will automatically adjust to stay proportional to the 100% scale intended height. See the Font Scaling Best Practices for more info. (I11518)

performTextInput
) will now request focus directly, using the semantics action, instead of clicking on the field. (I6ed05) - Adds support for cross axis spacing/arrangement using the
verticalArrangement
inFlowRow
andhorizontalArrangement
inFlowColumn
. We also remove the top-levelverticalAlignment
andhorizontalAlignment
inFlowRow/FlowColumn

constructor withvariationSettings
is now a stable API, and can be used to create new types of font descriptors. (I5adcc, b/261565807)- Introduced
PinnableContainer
api propagated by lazy lists via a composition local which allows to pin current item. This means such item will not be disposed when it is scrolled away from the view. For example,Modifier.focusable()
will pin the current focused item via this mechanism. (Ib8881, b/259274257, b/195049010) - Rewrote the way scrollables respond to
bringIntoViewRequesters
and focusables to better model the complexity of those operations and handle more edge cases. (I2e5fe, b/241591211, b/192043120, b/237190748, b/230756508, b/239451114) - More return type nullability of deprecated-hidden functions (Ibf7b0)

Known Issue
- When updating from
androidx.compose.foundation:1.4.0-alpha03
toandroidx.compose.foundation:1.4.0-alpha04
, you might experience ajava.lang.NoSuchFieldError
error. Here is where the issue was orginially reported. A fix has been submitted, and will be available on the next Compose update. As a work around, update yourandroidx.compose.material
andandroidx.compose.material3
libraries to the latest version(1.1.0-alpha04) or downgrade yourandroidx.compose.foundation
to 1.4.0-alpha03.
Version 1.4.0-alpha03
December 7, 2022
androidx.compose.foundation:foundation:1.4.0-alpha03
and androidx.compose.foundation:foundation-layout:1.4.0-alpha03
are released. Version 1.4.0-alpha03 contains these commits.
API Changes
- In UI tests using a Compose rule, continuations resumed during
withFrameNanos
callbacks will not be dispatched until after all frame callbacks have finished running. This matches the behavior of compose when running normally. However, tests that rely on the old behavior may fail. This should only affect code that callswithFrameNanos
orwithFrameMillis
directly, and has logic outside of callback passed to those functions that may need to be moved inside the callbacks. See the animation test changes in this CL for examples. - Added optional
onPerformTraversals: (Long) -> Unit
parameter toTestMonotonicFrameClock
constructor and factory function to run code afterwithFrameNanos
callbacks but before resuming callers' coroutines. (Idb413, b/254115946, b/222093277, b/255802670) - Introduce Page accessibility actions:
PageUp
,PageDown
,PageLeft
,PageRight
. Note that these are only available from API 29. (Ida4ab) - Introduce
HorizontalPager
andVerticalPager
, a way of showing composables in a Pager manner. IntroducedPagerState
to control the Pagers as well as query information about the Pager's current state. IntroducedPageSize
, a way of controlling the size of a Pager's page, this can be used to create a carousel like Pagers. IntroducedPagerSnapDistance
, a way to control how snapping will work in Pager's fling behavior. (I01120) - Introduced an overload in
SnapFlingBehavior.performFling
to help to understand where the fling will settle. (I569f6) - Removed
OverscrollEffect#isEnabled
. Instead of needing to remember and set this flag, just don't dispatch events to the overscroll effect in cases where you do not want overscroll to show (for example ifScrollableState#canScrollForward/backward
both return false). (I1a4b0, b/255554340, b/255557085) - Added
ScrollableState#canScrollForward
andScrollableState#canScrollBackward
to query whether aScrollableState
has room to scroll in either direction (whether it is at the minimum / maximum of its range). This defaults to true for backwards compatibility with existing implementations ofScrollableState
. Consumers can use this to show indication to the user that there is still room to scroll, and this could also be used to avoid dispatching delta toScrollableStates
that have no room to scroll in a given direction, to reduce unnecessary work. (Idf1a0, b/255557085) - Added an Modifier API to query ancestors scroll info. (I2ba9d, b/203141462)
- Used in
Clickable
to correctly delay press interactions, when gestures could become scroll events. - Fixed
Clickables
not correctly delaying ripples, when used inside anScrollable ViewGroup
. - Updated Drawers and Sheets to correctly delay presses in case gestures can become scroll events.
- Update
snapStepSize
naming to be consistent with other methods inSnapLayoutInfoProvider
. (Ife67c) - Added
EmojiCompat
toCompose
(Ibf6f9, b/139326806) - Renamed
consumedWindowInsets()
toconsumeWindowInsets()
andwithConsumedWindowInsets()
toonConsumedWindowInsetsChanged()
and made the Modifiers public. (Ie44e1)
Bug Fixes
- The crash with
Modifier.animateItemPlacement()
and Lazy grids was fixed. It was happening in some conditions when the new items count is smaller then the previous one. (I0bcac, b/253195989)

API Changes
- A new method,
awaitEachGesture()
, for gesture detectors was added. It operates similar toforEachGesture()
, but the loop over gestures operates entirely within theAwaitPointerEventScope
so events can't be lost between iterations. forEachGesture()
has been deprecated in favor ofawaitEachGesture()
because it allows events to be lost between gestures. (Iffc3f, b/251260206)- Added
WindowInsets.imeAnimationSourc
e andWindowInsets.imeAnimationTarget
to determine the animation progress and know where the IME will be after animation completes. (I356f1, b/217770337)

- Lazy lists and grids now have
userScrollEnabled
param which allows to disable scrolling via the user gestures. - A new experimental API called
LazyLayout
was added. It It is the API we use internally to power Lazy lists and grids. OverscrollEffect
API has been introduced as experimental. You can define custom overscroll effects as well as adding a standard platform one to custom scrollable containers.- Nested scrolling interoperability APIs have been introduced to allow for interoperability between views and compose scrolling actors.
- Mouse and trackpad scrolling has been added to all scrolling containers.

checkScrollableContainerConstraints()
which allows to check that we do not nest scrollable containers. You can use it when create your own scrollable lazy layouts viaLazyLayout
. (Id6fab, b/233352497) - Removed deprecated
LazyVerticalGrid
fromandroidx.compose.foundation.lazy
package. The new stable api is located inandroidx.compose.foundation.lazy.grid

IntervalList
andMutableIntervalList
. It allows to represent some list of values via multiple intervals. It will be useful when you want to define your own dsl similar to the one used byLazyColumn
where list items can be defined via multiple item/items calls. (I2d05e, b/228580728)
Bug Fixes
- Clarified the documentation for
WindowInsets.ime
to state thatime
insets are reported as far back as API 23, but only animated on 30+. (Ia7fc0, b/230756508) - Pressing the forward delete key when the cursor is at the end of a text field will no longer crash.

New Features
- This is the first beta release of 1.2!
API Changes
- Added experimental
BeyondBoundsInterval
that can be used by custom implementations ofLazyList
when they layout items beyond visible bounds (Ifabfb, b/184670295) LineHeightBehavior
is renamed asLineHeightStyle
LineVerticalAlignment
is renamed asLineHeightStyle.Alignment
- Renames
LineHeightTrim
is renamed asLineHeightStyle.Trim
- Default constructor values from
LineHeightStyle
is removed (I582bf, b/181155707) - Added default values for the optional members of
LazyLayoutItemProvider
interface. (Iba8a0) - In the
LazyLayoutItemProvider
api instead of a factory returning the composable lambda by index we now have a simpler composable function Item accepting the index. (Id2196) - LazyLayoutItemsProvider is renamed to LazyLayoutItemProvider (I0638c)
LazyLayoutItemsProvider.itemsCount
is renamed toitemCount
(Id409c)- Added Brush to
TextStyle
andSpanStyle
to provide a way to draw text with gradient coloring. (I53869, b/187839528) trimFirstLineTop
,trimLastLineBottom
attributes ofLineHeightBehavior
changed into a single enum:LineHeightTrim
.LineHeightTrim
have values of 4 states defined by two booleans:FirstLineTop
,LastLineBottom
, Both and None (Ifc6a5, b/181155707)Added
LineHeightBehavior
to theTextStyle
andParagraphStyle. LineHeightBehavior
controls whether line height is applied to the top of the first line and to the bottom of the last line. It also defines the alignment of line in the space provided byTextStyle
(lineHeight
).For example it is possible to get a behavior similar to what CSS defines via
LineHeightBehavior(alignment = LineVerticalAlignment.Center, trimFirstLineTop=false, trimLastLineBottom = false)
.trimFirstLineTop
,trimLastLineBottom
configurations works correctly only whenincludeFontPadding
is false. (I97332, b/181155707)Added experimental
imeNestedScroll()
modifier so that developers can control the IME through scrolling. (I60759)
Bug Fixes
- Fixed regression where text fields would not hide the keyboard when removed from the composition while focused. (I7a410, b/230536793, b/225541817)
- Support ellipsis when height is limited and doesn't fit all text lines (Ie528c, b/168720622)
BringIntoViewRequester.bringIntoView
will now always suspend until the request is either completed or was interrupted by a newer, non-overlapping request. Overlapping requests will be queued. (I43e7f, b/216790855)- Concurrent
BringIntoViewRequester.bringIntoView
calls for rectangles that are completely overlapping will now only honor the larger rectangle's request. (I34be7, b/216790855, b/184760918) - Turned on default
includeFontPadding
. It is possible to turn off theincludeFontPadding
usingTextStyle.platformTextStyle
attribute. In the near future we will change the default behavior however until that time this allows us to better integrate line height improvements (aosp/2058653) and solveTextField
clipping issues. (I01423, b/171394808) Modifier.bringIntoViewRequester
no longer usesonGloballyPositioned
. (I630f5)
External Contribution
MouseInjectionScope.scroll(delta = someDelta)
is now inverted on Android if we scroll vertically (if someDelta is positive, it will scroll downward) (Ifb697, b/224992993)
Version 1.2.0-alpha08
April 20, 2022
androidx.compose.foundation:foundation:1.2.0-alpha08
and androidx.compose.foundation:foundation-layout:1.2.0-alpha08
are released. Version 1.2.0-alpha08 contains these commits.
API Changes
- Display all available weights for systems fonts on Android when using
FontFamily.SansSerif
. This will use fallback font names like sans-serif-medium internally on API 21-28. This is a behavior change as previously only weights 400 and 700 were supported on API 21-28. (I380fe, b/156048036, b/226441992) - Paragraph and MultiParagraph are now accepting Constraints parameter. Passing
Constraints.maxHeight
is a no-op at the moment but will allow to do some calculation in the future, like ellipsizing based on the height. (I6afee, b/168720622) SubcomposeSlotReusePolicy.getSlotsToRetain()
now accepts a custom MutableSet-like class which doesn't allow adding new items in it. (Icd314)- Partial consumption (down OR position) has been deprecated in
PointerInputChange
. You can useconsume()
to consume the change completely. You can useisConsumed
to determine whether or not someone else has previously consumed the change. PointerInputChange::copy()
now always makes a shallow copy. It means that copies ofPointerInputChange
will be consumed once one of the copies is consumed. If you want to create an unboundPointerInputChange
, use constructor instead. (Ie6be4, b/225669674)- New experimental
LazyLayout
API is introduced. This allows you to build your own components likeLazyColumn
ofLazyVerticalGrid
. Note that the API is in its early stages and can be changed in the future releases. (Iba2bc, b/166591700) AndroidFont
now takestypefaceLoader
as a constructor parameter. (I2c971)WindowInsets
companion now exposes the visibility (whether they are on the screen, regardless of whether they intersect with the window) and the size they could be if they are available on the device, but not currently active. (I65182, b/217770337)
Version 1.2.0-alpha07

API that allows children of lazy layouts to prevent the currently composed items from being disposed (Ibbdd0, b/184670295) LazyListLayoutInfo
andLazyGridLayoutInfo
now havebeforeContentPadding
andafterContentPadding
fields (I3b628, b/200920410)- Added
KeyboardType.Decimal
as an alternative toKeyboard.Number
for specifically including decimal separator in IME. (Iec4c8, b/209835363) - Add new font descriptor Font(DeviceFontFamilyName) to optionally lookup system-installed fonts during font fallback chains. (I30468, b/219754572)
PointerEventType.Scroll
andPointerEvent.scrollDelta
are stable APIs now (I574c5, b/225669674)- Added temporary compatibility configuration for
includeFontPadding
inTextStyle/ParagraphStyle. includeFontPadding
can be changed viaTextStyle(platformStyle = PlatformTextStyle(includeFontPadding = true/false))
. This is a temporary configuration option to enable migration and will be removed. (If47be, b/171394808) - Updated
FontFamily.Resolver
to integrate System-wide bold text accessibility setting (I6c1e7) - The
consumeWindowInsets
extension property ofComposeView
allows developers to disable consumption of Android WindowInsets. This allows separateComposeViews
in the hierarchy to each applyWindowInsets
without interfering with each other. (I0ef08, b/220943142)
Version 1.2.0-alpha06

RequestFocus
semantics action to request focus on the focusable target. (I17b71) FocusOrder
has now been merged intoFocusProperties
andfocusProperties()
now has all the capabilities offocusOrder()
.FocusOrder
andfocusOrder()
have been deprecated.focusOrder()
that accepts afocusRequester
should be replaced with afocusRequester()
modifier in combination withfocusProperties()
. This allows the modifiers to have a stronger separation of concerns. (I601b7)WindowInsets.asPaddingValues(Density)
was added to allow developers to do the conversion without needing to be in composition. (I94c35)- Updated parsing of vector drawables to support auto mirroring to flip the content of a
VectorPainter
if the current layout direction is RTL. (I79cd9, b/185760237)
Bug Fixes
- Scroll modifiers (
Modifier.verticalScroll()
,Modifier.horizontalScroll()
, andModifier.scrollable()
) will now scroll to keep the focused composable visible if the scroll area is resized and the focused composable was previously visible. - TextFields will now be kept above the keyboard when they are focused and the keyboard is shown, when inside a non-lazy scrollable and the soft input mode is
ADJUST_RESIZE
. (I4a485, b/190539358, b/192043120, b/216842427)

was replaced with separateLazyGridItemInfo.UnknownRow
andLazyGridItemInfo.UnknownColumn
(I56d51)LazyVerticalGrid
/LazyHorizontalGrid
and all related apis were moved into.grid
subpackage. Please update your imports fromandroidx.compose.foundation.lazy
toandroidx.compose.foundation.lazy.grid

is now turned off by default. The clipping issues as a result ofincludeFontPadding=false
is handled and no clipping should occur for tall scripts. (I31c84, b/171394808) - Measured interface now exposes parentData property (I3313f)
- Introduced experimental
Modifier.onFocusedBoundsChanged
to allow observing the bounds of child focusables. (I14283, b/220030968, b/190539358, b/192043120, b/216842427) - LazyHorizontalGrid was added. (I61ae7, b/191238807)

are released. Version 1.2.0-alpha04 contains these commits.
API Changes
BringIntoViewResponders
are no longer required to manually pass requests up to parent responders, and are instead required to immediately return the rectangle they want their parent to bring into view. (I8e66a)- Support async font loading in Text (I77057, b/214587005)
LazyVerticalGrid
now supportsline breaking
before items with span not fitting inside the current line. (I05c40, b/207462103)- Renamed
excludeFromSystemGestures
tosystemGesturesExclusion
(I19526) LazyVerticalGrid
now supports reverseLayout. (I6d7d7, b/215572963, b/211753558)- Add
WindowInsets.only()
method to allow developers to include only dimensions from the WindowInsets. (I14c94, b/217768486) Added
ComposableTarget
,ComposableTargetMarker
andComposableOpenTarget
that allows compile time reporting of when a composable function is called targeting an applier it was not designed to use.In most cases the annotations can be inferred by the compose compiler plugin so using these annotation directly should be rare . The cases that cannot be inferred include creating and using a custom applier, abstract composable functions (such as interface methods), fields or global variables that are composable lambdas (local variables and parameters are inferred), or when using
ComposeNode
or a related composable functions.For custom appliers the composable functions that calls
ComposeNode
orReusableComposeNode
need to add aCompoableTarget
annotation for the function and any composable lambda parameter types. It is recommended, however, to create an annotation that is annotated withComposableTargetMarker
and then the marked annotation be used instead ofComposableTarget
directly. A composable annotation marked withComposableTargetMarker
is equivalent to aComposbleTarget
with the fully qualified name of the attribute class as the applier parameter. For an example of usingComposableTargetMarker
seeanroidx.compose.ui.UiComposable
. (I38f11)
Bug Fixes
- Now it is allowed to pass negative scroll offsets into
LazyGridState.scrollToItem()
andLazyGridState.animateScrollToItem()
. (I025c6, b/211753558) - Support async font loading for TextField. (Icc4bf, b/214587005)

are released. Version 1.2.0-alpha03 contains these commits.
API Changes
notifyFocusedRect
methods inTextInputSession
andTextInputService
are now deprecated and won't be called. UseBringIntoViewRequester
instead. (Ia4302, b/192043120, b/216842427, b/178211874)- Animations were enabled for items of lazy grids with Modifier.animateItemPlacement(). (Ib6621, b/211753218)
BringIntoViewRequester
now propagates requests to the hosting Android View. (Ia7a51)FontFamilyResolver
is now available viaLocalFontFamilyResolver.current
- Added
createFontFamilyResolver(context)
andcreateFontFamilyResolver(context, coroutineScope)
to create new FontFamily resolvers outside of compose usage. - Paragraph and MultiParagraph now take
FontFamily.Resolver
TextLayoutResult.layoutInput.fontFamilyResolver
now contains the resolver used for this layout, deprecatedTextLayoutResult.layoutInput.resourceLoader
as it is no longer used. (Id5a45, b/174162090)
- Added
- Added
AndroidFont
, a new low-level API for providing new types of font resource descriptors on Android. For example, loading fonts from an app-specific backend, optionally locating pre-installed fonts on-device, or loading a font from a resource not provided by the current Font factories.- Expanded
Font.ResourceLoaded
API to support optional and async font loading. It is not recommended that application developers use this API directly. To add new types of fonts see AndroidFont. Font.AndroidResourceLoader
extension function allows construction of aFont.ResourceLoader
when outside of composition.- Added
loadingStrategy
parameter to resource-based fonts, to allow async loading when resource font references downloadable fonts XML. (Ie5aea, b/174162090)
- Expanded
Typeface(FontFamily)
constructor is deprecated. This was previously used to preload fonts, which may take up to 10 seconds for downloadable fonts. With downloadable fonts, this call may block for 10 seconds. Instead useFontFamilyResolver.preload
fontResource(FontFamily): Typeface
is deprecated. This was previously used to preload fonts, which may take up to 10 seconds for downloadable fonts. Instead useFontFamilyResolver.preload
(If8e7c, b/174162090)
- You can now specify the content type for the items of
LazyVerticalGrid
- item/items functions onLazyGridScope
now accept such parameter. Providing such information helps item composition reusing logic to make it more efficiently and only reuse the content between the items of similar type. (I7b355, b/215372836) LazyListLayoutInfo
andLazyGridLayoutInfo
now have new properties:viewportSize
,orientation
,reverseLayout
(Ifc8ed, b/200920410)- You can now specify the content type for the items of LazyColumn/LazyRow - item/items functions on LazyListScope now accept such parameter. Providing such information helps item composition reusing logic to make it more efficiently and only reuse the content between the items of similar type. (I26506)
SubcomposeLayoutState
constructor acceptingmaxSlotsToRetainForReuse
is now deprecated. Instead there is a new constructor acceptingSubcomposeSlotReusePolicy
- a new interface allowing more granular control on what slots should be retained for the future reuse. (I52c4d)- Adds Modifiers for WindowInsets, both for padding and sizing. This allows some content to extend into the inset area, and still have primary content stay out of the inset area. For example, windowInsetsPadding can be used to pad the content area to avoid areas that may be fully or partially covered. (Id0395, b/213942085)
Bug Fixes
- TextFields will now be kept above the keyboard when they are

February 9, 2022
androidx.compose.foundation:foundation:1.1.0
and androidx.compose.foundation:foundation-layout:1.1.0
are released. Version 1.1.0 contains these commits.
Important changes since 1.0.0
- Stable support for the Android 12 Overscroll effect
- Improvements to touch target sizing
- Note that, with respect to Compose 1.0, Material components will expand their layout space to meet Material accessibility guidelines for touch target size. For instance, Button touch target will expand to a minimum size of 48x48dp, even if you set the Button's size to be smaller. This aligns Compose Material to the same behavior of Material Design Components, providing consistent behavior if you mix Views and Compose. This change also ensures that when you create your UI using Compose Material components, minimum requirements for touch target accessibility will be met.
- Stable support for Navigation Rail
- Graduates a number of previously experimental APIs to stable
- Support for newer versions of Kotlin

instead. (I3c3e8, b/189951065) - change enum Role and LiveRegionMode to inline classes with private constructor (Id1890)
- KeyboardCapitalization is converted into inline class. (Id5a1c)
- TextOverflow is changed to an inline class. (I433af)
Bug Fixes
- Now when you specify the unique keys for LazyColumn/Row items the scroll position will be maintained based on the key, which means if you add/remove items before the current visible item the item with the given key will be kept as the first visible one. (Id263f, b/184257857)
- Key constants are @ExperimentalComposeUiApi for now. Consuming code can declare private constants prior to stabilization. (Ia5d48)

used by testing frameworks to install an alternative mechanism to await
or achieve quiescence. Use
AndroidComposeTestRule.setIdlingStrategyFactory()
before your test starts to install your own strategy. (I608fa)
Added Profile Rules
This release adds profile rules to the following compose modules (I14ed6):
- androidx.compose.animation
- androidx.compose.animation-core
- androidx.compose.foundation
- androidx.compose.foundation-layout
- androidx.compose.material
- androidx.compose.material-ripple
- androidx.compose.runtime
- androidx.compose.ui
- androidx.compose.ui.geometry
- androidx.compose.ui.graphics
- androidx.compose.ui.text
- androidx.compose.ui.text
- androidx.compose.ui.unit
- androidx.compose.ui.util
What are profile rules?
Profile rules for a library are specified in a text file
baseline-prof.txt
located in thesrc/main
or equivalent directory. The file specifies a rule per line, where a rule in this case is a pattern for matching to methods or classes in the library. The syntax for these rules is a superset of the human-readable ART profile format that is used when usingadb shell profman --dump-classes-and-methods ...
. These rules take one of two forms to target either methods or classes.A method rule will have the following pattern:
<FLAGS><CLASS_DESCRIPTOR>-><METHOD_SIGNATURE>
And a class rule will have the following pattern:
<CLASS_DESCRIPTOR>
Here
<FLAGS>
is one or more of the charactersH
,S
, andP
to indicate whether or not this method should be flagged as "Hot", "Startup", or "Post Startup".The
<CLASS_DESCRIPTOR>
is the descriptor for the class that the targeted method belongs to. For example, the classandroidx.compose.runtime.SlotTable
would have a descriptor ofLandroidx/compose/runtime/SlotTable;
.The
<METHOD_SIGNATURE>
is the signature of the method, and includes the name, parameter types, and return types of the method. For example, the methodfun isPlaced(): Boolean
onLayoutNode
has the signatureisPlaced()Z
.These patterns can have wildcards (
**
,*
, and?
) in order to have a single rule encompass multiple methods or classes.
What do the rules do?
A method that has the flag
H
indicates that this method is a "hot" method, and should be compiled ahead of time.A method that has the flag
S
indicates that it is a method which is called at startup, and should be compiled ahead of time to avoid the cost of compilation and interpreting the method at startup time.A method that has the flag
P
indicates that it is a method which is called after startup.A class that is present in this file indicates that it is used during startup and should be pre-allocated in the heap to avoid the cost of class loading.
How does this work?
- Libraries can define these rules which will be packaged in AAR artifacts. When an app is then built which includes these artifacts, these rules are merged together and the merged rules are used to build a compact binary ART profile that is specific to the app. ART can then leverage this profile when the app is installed on devices in order to ahead-of-time compile a specific subset of the application to improve the performance of the application, especially the first run. Note that this will have no effect on debuggable applications.
Version 1.0.0-beta08

API Changes
- NestedScrollSource enum is replaced by an inline class. (Ie321b, b/187055290)
- Refactored enum usages to inline classes to avoid issues with exhaustive when statements when new enum values are added. (I2b5eb)
- Adds a tap timeout to clickable / toggleable to prevent showing a ripple during a scroll / drag (Ia2704, b/168524931)
- ContentDescription and Text semantics properties are no longer single values but lists. This enables to merge them as they are instead of concatenations. Also provided better testing APIs to utilize these changes (Ica6bf, b/184825850)
Modifier.focusModifier()
is deprecated and replaced byModifier.focusTarget()
(I6c860)- KeyboardType enum is replaced by an inline class. (I73045, b/187055290)

- Fixed an issue where ripples / other indication would sometimes get stuck on a long click when using Modifier.combinedClickable (I2298c, b/186223077)
- Now
detectDragGesures
,detectVerticalGestures
, anddetectHorizontalGestures
will consume the position change automatically, no need to call change.consumePositionChange in the onDrag callbacks (I42fc4, b/185096350, b/187320697) Modifier.onGloballyPositioned()
was changed to report the coordinates of this modifier in the modifier chain, not the layout coordinates after applying all the modifiers. This means that now the ordering of modifiers is affecting what coordinates would be reported. (Ieb67d, b/177926591)
Version 1.0.0-beta07

SemanticsActions.ScrollToIndex
to scroll a list with indexed items to the item with a certain index, andSemanticsProperties.IndexForKey
to get the index of an item in a list with keyed items. Both actions are implemented by LazyList.- Added
SemanticsNodeInteraction.performScrollToIndex
that scrolls a list to the given index, andSemanticsNodeInteraction.performScrollToKey
that scrolls a list to the item with the given key. (I4fe63, b/178483889, b/161584524)

are released. Version 1.0.0-beta05 contains these commits.
API Changes
- FlingBehavior interface is now marked as @Stable. All implementations should comply with the
@Stable
contract. (I93354, b/184830577)
Bug Fixes
- Fixed
ACTION_SCROLL_FORWARD

androidx.compose.foundation:foundation:1.0.0-beta04
and androidx.compose.foundation:foundation-layout:1.0.0-beta04
are released. Version 1.0.0-beta04 contains these commits.
API Changes
- Rename hideSoftwareKeyboard and showSoftwareKeyboard on
SoftwareKeyboardController to
hide()
andshow()
respectively.- Provide the full CompositionLocal interface for LocalSoftwareKeyboardController, allowing it to be set (especially useful in tests) (I579a6)
TextOverflow.Visible
is introduced. (Ic8f89)- Public instances of
RowScope
,ColumnScope
,BoxScope
,BoxWithConstraintsScope
were removed. (I4e83e, b/181869067)
Bug Fixes
- Fixed the issue when items of
LazyColumn
/LazyRow
located on the edges were incorrectly positioned after fast fling (Ie4d13, b/183877420) Prior to this change, local composable functions were skippable based on their parameters. After this change, no local composable functions will skip. This change is done because it is common and expected for local functions to capture parameters from the parent and them skipping is a common source of bugs.
To summarize, consider the example:
@Composable fun Counter(count: Int, onCountChange: (Int) -> Unit) { @Composable fun ShowCount() { Text("Count: $count") } ShowCount() Button(onClick={ onCountChange(count + 1) }) { Text("Increment") } }
Prior to this change, the
ShowCount
composable function would always skip, even after thecount
parameter was updated. This is no longer the case. (I5648a)

API Changes
- Multiple small optimizations in LazyColumn measuring logic were added (Ic6889)
- Added new
LocalSoftwareKeyboardController
composition local API to replace previous SoftwareKeyboardController interface on TextField. (I5951e, b/168778053) - Added new
LocalSoftwareKeyboardController
composition local API to replace previous SoftwareKeyboardController interface on TextField. (I84472, b/168778053)
Bug Fixes
- Enforce restrictions on public usage of experimental APIs (I6aa29, b/174531520)
Version 1.0.0-beta01
February 24, 2021
androidx.compose.foundation:foundation:1.0.0-beta01
and androidx.compose.foundation:foundation-layout:1.0.0-beta01
are released. Version 1.0.0-beta01 contains these commits.
This is the first release of Compose 1.0.0 Beta.
API Changes
- onStart callback has been added to
detectDragGestures
(I67269, b/179995594) - Modifiers for sizing to intrinsics are no longer experimental. (I15744)
- Removed dp assertions (I798d2)
- Removed SoftwareKeyboardController callback from all text fields to be replaced by a new API shortly. (Iae869, b/168778053)
- MeasureBlocks was renamed to MeasurePolicy which became a fun interface. Layout APIs were updated / simplified to use MeasurePolicy. (Icab48, b/167662468, b/156751158)
InteractionState
has been replaced with[Mutable]InteractionSource
- Interfaces are responsible for emitting / collecting Interaction events.
- Instead of passing
interactionState = remember { InteractionState() }
to components such asButton
andModifier.clickable()
, useinteractionSource = remember { MutableInteractionSource() }
. - Instead of:
Interaction.Pressed in interactionState
you should instead use the extension functions on InteractionSource, such as InteractionSource.collectIsPressedAsState(). - For complex use cases you can use InteractionSource.interactions to observe the stream of Interactions. See the InteractionSource documentation and samples for more information.
- (I85965, b/152525426, b/171913923, b/171710801, b/174852378)
- Removed deprecated LayoutCoordinates methods, use function instead of the property for positionInParent and boundsInParent (I580ed, b/169874631, b/175142755)
- Created new TextInputSession for input sessions from low level text components such as CoreTextField. (I8817f, b/177662148)
- Placeable now exposes measuredSize, representing the size which the child layout actually measured to. This size might not respect the measurement constraints. (Ib2729, b/172560206, b/172338608)
- Add selectionGroup modifier that allows to mark collection of Tabs or RadioButtons for accessibility purposes (Ie5c29)
Add LazyListState.animateScrollToItem
This method smooth scrolls to a specific item in the list. (I4bfd7)
ScrollableState.smoothScrollBy() was renamed to animateScrollBy() LazyListState.snapToItemIndex() was renamed to scrollToItem() ScrollState.smoothScrollTo() was renamed to animateScrollTo() (I35ded)
Modifier.zoomable has been replaced my Modifier.transformable. smoothPanBy, smoothRotationBy have been added as a functionality. (Ifc32b, b/175294473)
The
defaultFactory
forcompositionLocalOf
andstaticCompositionLocalOf
is now required instead of optional.This changes removes a potential type error for non-nullable types where no default factory was provided. Previously this would provide a null reference for a non-nullable type.
For nullable types consider supplying
{ null }
as the default factory.We do not recommend using locals with non-nullable types unless a sensible default can be provided. If no sensible default exists, the
defaultFactory
lambda should throw an exception. However throwing an exception means that consumers of the local will have an implicit dependency on it being provided that is not enforced by the type system. (Ifbd2a)Changed
Indication#createIndication()
toIndication#rememberUpdatedIndication(InteractionState)
and removesInteractionState
parameter from IndicationInstance#drawIndication()
. IndicationInstance should only be responsible for drawing visual effects, and not launching animations / writing state in response to InteractionState changes. These animations and state writes should happen withinrememberUpdatedIndication()
instead. Theindication
parameter inModifier.indication
was also changed to be a required parameter. (Ic1764, b/152525426)Text actions now check focus automatically (I13777, b/179648629)
Removed
runBlockingWithManualClock
(I15cdc, b/179664814)Scroll position in Modifier.verticalScroll()/horizontalScroll() is represented with Ints now (I81298)
smoothScrollBy and scrollBy methods' packages changed to
androidx.compose.foundation.gestures.*
(I3f7c1, b/175294473)FlingConfig has been renamed to FlingBehavior now allows for customization of suspend animation rather than predefined Decays. (I02b86, b/175294473)
Size modifiers were renamed. Modifier.width/height/size were renamed to requiredWidth/requiredHeight/requiredSize. Modifier.preferredWidth/preferredHeight/preferredSize were renamed to width/height/size. (I5b414)
defaultMinSizeConstraints was renamed to defaultMinSize. (I4eaae)
Modifier.tapGestureFilter has been removed. Use
Modifier.pointerInput { detectTapGestures(...) }
instead. (I266ed, b/175294473)partial consumption was removed from pointer input system. The recommended way of coordinating partial consumtion is Modifier.nestedScroll. (Ie9c9b)
Orientation has been moved to foundation package. VelocirtTracker moved from ui.gesture to ui.input.pointer. (Iff4a8, b/175294473)
AnimationClockObservable and subclasses have been removed. AnimatedFloat has been removed. (Icde52, b/177457083)
drawerState.open() and drawerState.close() are now suspending functions. Use rememberCoroutineScope() to get the scope of the composition to call them (I16f60, b/175294473)
Providers has been renamed to CompositionLocalProvider
- The Composition constructor no longer accepts a key parameter, and has been deprecated.
- currentCompositeKeyHash has been turned into a composable top level property instead of a composable top level function.
- CompositionData and CompositionGroup have been moved to the androidx.compose.runtime.tooling namespace
- ComposableLambda has been made an interface instead of a concrete class, and no longer has type parameters.
- ComposableLambdaN has been made an interface instead of a concrete class, and no longer has type parameters.
- The snapshotFlow function has been moved to the androidx.compose.runtime namespace
- the merge method of SnapshotMutationPolicy is no longer experimental
- The
@TestOnly
top level clearRoots function has been removed. It is no longer necessary. - keySourceInfoOf and resetSourceInfo functions have been removed. They are no longer necessary.
- Composer.collectKeySourceInformation has been removed. It is no longer necessary.
- isJoinedKey, joinedKeyLeft, and joinedKeyRight methods have been removed. They are no longer necessary.
- Various top level APIs have been moved and reorganized into different files. Due to Kotlin’s file class semantics, this will break binary compatibility but not source compatibility, so should not be an issue for most users.
- (I99b7d, b/177245490)
Modifier.scrollable has been reworked. Now it uses Scrollable interface instead of ScrollableController class (I4f5a5, b/174485541, b/175294473)
Modifier.draggable now accepts DraggableState instead of a simple lambda. you can create state via
rememberDraggableState { delta -> }
to get the same behaviour as before (Ica70f, b/175294473)requiredWidth(IntrinsicSize) and requiredHeight(IntrinsicSize) modifiers were added for required sizing to intrinsic sizes. (I0a6b4)
Deprecated

and androidx.compose.foundation:foundation-layout:1.0.0-alpha12
are released. Version 1.0.0-alpha12 contains these commits.
API Changes
- Modifier.pointerInput now requires remember keys to indicate when the pointer input detection coroutine should restart for new dependencies. (I849cd)
- Testing update: hasText() will check for both input and label/hint/placeholder texts in the text field (Iab803)
- PaddingValues.Absolute was added and can be used in APIs accepting PaddingValues. (Ia5f30)
- onImeActionPerformed is deprecated. use KeyboardActions instead (If0bbd, b/179071523)
- In order to better match naming conventions with ImageBitmap and ImageVector, ImagePainter has been renamed to BitmapPainter to parallel VectorPainter. (Iba381, b/174565889)
- Better substring test APIs with substring now as an argument (Icbe78)
- Introduced an
InfiniteAnimationPolicy
coroutine context element that will be applied in infinite animations. By default no policy is installed, except when running tests withComposeTestRule
. (I50ec4, b/151940543) - Animatable.snapTo and Animatable.stop are now suspend functions (If4288)
- ComponentActivity.setContent has moved to androidx.activity.compose.setContent in the androidx.activity:activity-compose module. (Icf416)
- Destructuring and copy() methods have been removed from several classes where they were rarely used. (I26702, b/178659281)
Custom keys support for LazyColumn/LazyRow was added. This allows us to smarter handle items reordering. So the state you stored in remember {} blocks will move together with the item when you reorder elements or removed the item from the middle.
LazyColumn { items(users, key = { user -> user.id }) { ... } }
Changed Indication#createInstance to be @Composable, and changed LocalIndication to contain an Indication, not () -> Indication. (I5eeea, b/157150564)
Constraints.enforce
was replaced withConstraints.constrain
. (I8b8ea)loadFontResource is deprecated. Use fontResource instead. imageResource, loadImageResource, vectorResource, and loadVectorResource are deprecated. Use painterResource instead. (I6b809)
For performance reasons, ScrollAxisRange semantics now takes lambdas returning Floats instead of direct Float values. (If4a35, b/178657186)
Added EditableText semantics to mark editable input text of the text field for accessibility and corresponding test methods to check the semantics (I8e07a)
Modifier.clickable now doesn't have double and long click support. Use Modifier.combinedClickable to achieve this functionality. (Iafad1)
toIntPx() was renamed to roundToPx(). (I9b7e4, b/173502290)
IntBounds was renamed to IntRect and the API was improved. (I1f6ff)
Modifier.dragGestureFilter has been deprecated. Use
Modifier.pointerInput { detectDragGestures (...)}
instead. Alternatively, use Modifier.draggable for one axis drags (I0ba93, b/175294473)Renamed Ambients to match the Ambient -> CompositionLocal rename. Ambients used to be named AmbientFoo, now CompositionLocals are named LocalFoo. (I2d55d)
Selection was moved to foundation. (I7892b)
Similarly to how we previously removed
state { 0 }
composable and now promote usage likeremember { mutableStateOf(0) }
we are going to removesavedInstanceState { 0 }
composable. You should userememberSaveable { mutableStateOf(0) }
instead and it will save and restore automatically if the type used inside the MutableState can be stored in the Bundle. If previously you were passing a custom saver object now you need to use a new overload of rememberSaveable which has thestateSaver
parameter. The usage will look like this:val holder = rememberSaveable(stateSaver = HolderSaver) { mutableStateOf(Holder(0)) }
(Ib4c26, b/177338004)Added password semantics for accessibility (I231ce)
Added ProgressBarRangeInfo.Indeterminate to mark indeterminate progress bars for accessibility (I6fe05)
Playtime in animation is now unfiied to nanoseconds (If776a)
@ComposableContract has been deprecated in favor of three more specific annotations.
@ComposableContract(restartable = false)
has become@NonRestartableComposable
@ComposableContract(readonly = true)
has become@ReadOnlyComposable
@ComposableContract(preventCapture = true)
has become@DisallowComposableCalls
@ComposableContract(tracked = true)
has been removed. (I60a9d)emptyContent()
and(@Composable () -> Unit).orEmpty()
utilities have been deprecated as they no longer have any positive performance impact or value (I0484d)Recomposers can now be closed. Closed recomposers will continue recomposition until composition child coroutines complete. Recomposer.shutDown renamed to cancel to contrast with close. (Ib6d76)
APIs related to LazyVerticalGrid are marked as experimental (Ia53e3, b/178519862)
rememberSavedInstanceState() was renamed to rememberSaveable() and moved to androidx.compose.runtime.saveable package. (I1366e, b/177338004)
RestorableStateHolder was renamed to SaveableStateHolder and moved to androidx.compose.runtime.saveable package. Inner method RestorableStateProvider was renamed to SaveableStateProvider. Generic type was removed so you can just pass Any as a key. Experimental annotation is not needed anymore. (I0902e, b/174598702)
Saver, listSaver(), mapSaver(), autoSaver was moved from androidx.compose.runtime.savedinstancestate to androidx.compose.runtime.saveable (I77fe6)
Artefact androidx:compose:runtime:runtime-saved-instance-state was renamed to androidx:compose:runtime:runtime-saveable (I6dcac)
Many longstanding deprecated APIs in the ui package are deleted. (I2f2dc)
The compose:runtime-dispatch artifact is now deprecated. MonotonicFrameClock can now be found in compose:runtime and AndroidUiDispatcher can be found in compose:ui. (Ib5c36)
Parameters on RounderCornerShape, CutCornerShape and CornerBasedShape were renamed from left/right to start/end in order to support the shape's auto mirroring in the rtl direction. AbsoluteRounderCornerShape and AbsoluteCutCornerShape were introduced for the cases when auto-mirroring is not desired. (I61040, b/152756983)
canDrag has been removed from the Modifier.scrollable. (Id66e7, b/175294473)
The API the Compose compiler plugin targets has been refactored to use an interface instead of a concrete class. The interface also no longer uses a type parameter.
This is an internal change that should not effect source code compatibility but is a binary breaking change. (I3b922, b/169406779)
Modifier.scaleGestureFilter has been removed. Use Modifier.zoomable instead. Alternatively, use
Modifier.pointerInput { detectMultitouchGestures { ... }}
(Id5da1, b/175294473)AnimatedValue/Float is now deprecated. Please use Animatable instead. (I71345, b/177457083)
- Removed CoreText and CoreTextField from public API
- Removed deprecated SelectionContainer overload (I99c19)
Remove deprecated non-suspend scrolling functions Continuing with the changes from last release, the non-suspend scrolling functions are now removed entirely. Please convert to the suspend functions with the same names. A coroutine scope can be obtained via rememberCoroutineScope(). (I3d39c, b/178169563)
androidx.compose.foundation.layout.ConstraintLayout was deprecated in favor of androidx.constraintlayout.compose.ConstraintLayout. You will need to add a dependency on
androidx.constraintlayout:constraintlayout-compose:1.0.0-alpha01
. (I87adc)tapGestureFilter, doubleTapGestureFilter, longPressGestureFilter and pressIndicaitonGestureFilter have been deprecated. Use Modifier.clickable or Modifier.pointerInput with detectTapGestures function instead. (I6baf9, b/175294473)
Removed
Recomposer.current()
. [Abstract]ComposeView now default to lazily created, window-scoped Recomposers driven by the ViewTreeLifecycleOwner for the window. Recomposition and withFrameNanos-based animation ticks are paused while the host Lifecycle is stopped. (I38e11)Recomposer.runningRecomposers now offers a global StateFlow of read-only RecomposerInfo for observing ongoing composition state in the process. Prefer this API to Recomposer.current(), which is now deprecated. (If8ebe)
Version 1.0.0-alpha11
January 28, 2021
androidx.compose.foundation:foundation:1.0.0-alpha11
and androidx.compose.foundation:foundation-layout:1.0.0-alpha11
are released. Version 1.0.0-alpha11 contains these commits.
API Changes
Deprecate non-suspend scrollBy, remove non-suspend scrollTo
We now recommend using suspend functions to control scrolling and wait for the scroll to finish. We are deprecating and/or removing the non-suspend versions of these functions as part of this transition. (Ie9ced)
Deprecate non-suspend smoothScrollBy We now recommend using suspend functions to control scrolling and wait for the scroll to finish. We are deprecating the non-suspend versions of these functions as part of this transition. (I12880)
Content description parameter has been added to the Image and Icon. It is used to provide description to the accessibility services (I2ac4c)
BasicTextField received a new parameter called 'decorationBox'. It allows to add the decorations like icons, placeholder, label and similar to the text field and increase the hit target area of it. (I16996)
canDrag parameter has been removed from the Modifier.draggable (Ic4bec, b/175294473)
AnimatedFloat.fling that accepts FlingConfig has been removed. Please use suspend Animatable.animateDecay instead. (I4659b, b/177457083)
Removed
data class
from the following classes:- InlineTextContent
- LocaleList
- (I605c7)
clickable, toggleable and selectable can be created outside of composition now (I0a130, b/172938345, b/175294473)
ScrollableColumn/Row were deprecated. Using ScrollableColumn is less efficient comparing to LazyColumn when you have a large scrolling content because with LazyColumn we can only compose/measure/draw visible elements. To prevent users from going inefficient way we decided to deprecate ScrollableColumn and ScrollableRow and promote usages of LazyColumn and LazyRow instead. Users can still decide they don't need the lazy behaviour and use the modifiers directly like this: Column(Modifier.verticalScroll(rememberScrollState())) (Ib976b, b/170468083)
New
items(count: Int)
factory method for scope of LazyColumn/LazyRow/LazyVerticalGrid.items(items: List)
anditemsIndexed(items: List)
are now extension functions so you have to manually import them when used. New extension overloads for Arrays: items(items: Array) and itemsIndexed(Array) (I803fc, b/175562574)The deprecated AbsoluteArrangement was removed. (Iffa96, b/177641870)
The propagateMinConstraints parameter was added to Box, for specifying whether the incoming min constraints should be passed to the content of the Box or not. Default is false. (I0125b, b/152613457)
Bug Fixes
- onCommit, onDispose, and onActive have been deprecated in favor of SideEffect and DisposableEffect APIs (If760e)
- WithConstraints was reworked as BoxWithConstraints and moved to foundation.layout. (I9420b, b/173387208)
Changes to factory functions for Font/FontFamily/Typeface
- Added factory functions that start with capital letter
- Deprecated previous factory functions with lowercase first letters
- New factory functions return the FontFamily instead of subclasses
- Hid constructors of the subclasses, so that they can only be constructed via factory functions.
- Renamed Font.asFontFamily to Font.toFontFamily
- (I42aa7)
Introduced
ComposeContentTestRule
, which extendsComposeTestRule
and definessetContent
, which has been removed fromComposeTestRule
. Added a factory methodcreateEmptyComposeRule()
that returns aComposeTestRule
and does not launch an Activity for you. Use this when you want to launch your Activity during your test, e.g. usingActivityScenario.launch
(I9d782, b/174472899)animateAsState is now animateFooAsState, where Foo is the type of the variable being animated. e.g. Float, Dp, Offset, etc (Ie7e25)
Density is now receiver scope for Arrangement interfaces. (I18aad)
TextFieldValue accepts AnnotatedString. However this is an API only change and multi-style text editing is not implemented yet.
- Removed
initial
from EditingBuffer constructor parameters. (I326d5)
- Removed
invalidate and compositionReference() are now deprecated in favor of currentRecomposeScope and rememberCompositionReference respectively. (I583a8)
AnnotatedString is changed to extend from kotlin.CharSequence. Therefore length and subSequence are now instance functions, and extension functions are removed. (Iaf429)
Duration and Uptime will be replace with Long milliseconds, and this step removes the dependency of pointer input on those classes. (Ia33b2, b/175142755, b/177420019)
RememberObserver replaces CompositionLifecycleObserver and CompositionLifecycleObserver is now deprecated.
RememberObserver
is a replacement forCompositionLifecycleObserver
with modified semantics and renamed methods. Changing to the new API can be done mechanically for objects that are only remembered once which is, and continues to be, the recommended practice. However, if a reference was remembered more than once in a compositiononRemembered
is called for each reference whereonEnter
is only called once.onEnter
was called multiple time if the object was used in subcompositions, such asWithConstraints
andScaffold
making the singleonEnter
call guarantee unreliable and it was removed forRememberObserver
.RememberObserver
addsonAbandoned
which is called if theRememberObserver
instance is returned from the callback passed toremember
but was not remembered in the composition state and, therefore, will never haveonRemembered
called. This can occur if an exception terminates composition before completing or the composition is discarded because the state is was producing a composition for is no longer current or otherwise is no longer needed. If the instance ofRememberObserver
following the single reference recommendation above is tracking an external resource bothonForgotten
andonAbandoned
each indicate that the resource is no longer needed. If the object is tracking work started or resources allocated inonRemembered
,onAbandoned
can be ignored as it will not be called ifonRemembered
is called. (I02c36)Renamed TransformedText.transformedText to TransformedText.text
- TransformedText is no longer a data class (Ie672a)
The following classes are not data classes anymore:
- AnnotatedString
- ParagraphStyle
- SpanStyle
- TextStyle
- FontWeight
- TextDecoration
- TextGeometricTransform
- TextIndex
- TextLayoutResult
- TextLayoutInput (Iaff99)
Removed experimental monotonicFrameAnimationClockOf methods (Ib753f, b/170708374)
Deprecated global coordinates methods and made new window-based coordinates methods. (Iee284)
Please use ImeAction.None instead of ImeAction.NoAction
- Please use ImeAction.Default instead of ImeAction.Unspecified (Ie1bcc)
FocusRequester.createRefs is now marked as experimental as it might change. (I2d898, b/177000821)
SemanticsPropertyReceiver.hidden was renamed to invisibleToUser and marked @ExperimentalComposeUiApi. AccessibilityRangeInfo was renamed to ProgressBarRangeInfo. stateDescriptionRange was renamed to progressBarRangeInfo. AccessibilityScrollState was renamed to ScrollAxisRange. horizontalAccessibilityScrollState was renamed to horizontalScrollAxisRange. verticalAccessibilityScrollState was renamed to verticalScrollAxisRange. (Id3148)
Changed VisualTransformation to be a functional interface (I3bba4)
Leverage TestCoroutineDispatcher in testing (I532b6)
Removed PointerInputData and modified PointerInputChange to give it all of PointerInputData's fields. Made PointerInputEvent and PointerInputEventData internal because they aren't used in any public API. (Ifff97, b/175142755)
Renamed TextInputService.onStateUpdated as updateState (Id4853)
Remove displaySize as it should be avoided. Typically it is better to use size of onRoot() or window size at least. (I62db4)

- Moved nativeClass to ui module and made it internal. Updated usages of nativeClass in equals implementations to use 'is MyClass' instead. (I4f734)
- FlowRow and FlowColumn were deprecated. Please use a custom layout instead. (I09027)
- Modifier.focus() and Modifier.focusRequester() are deprecated. Use Modifier.focusModifier() and Modifier.focusReference() instead. (I75a48, b/175160751, b/175160532, b/175077829)

Animatable
that ensures mutual exclusiveness among its animations. New DecayAnimationSpec to support multi-dimensional decay animation (I820f2, b/168014930) - Added support for disabled and read-only text fields (I35279, b/171040474, b/166478534)
animate()
is now replaced withanimateAsState()
, which returns aState<T>
instead ofT
. This allows better performance, as the invalidation scope can be narrowed down to where the State value is read. (Ib179e)- Add Semantics role API and add Role as a parameter to clickable, selectable and toggleable SemanticsModifier. Changed Modifier.progressSemantics so that Slider can also use it. (I216cd)
- The native keyEvent can now be accessed through keyEvent.nativeKeyEvent (I87c57, b/173086397)
Version 1.0.0-alpha09

androidx.compose.foundation:foundation:1.0.0-alpha09
and androidx.compose.foundation:foundation-layout:1.0.0-alpha09
are released. Version 1.0.0-alpha09 contains these commits.
API Changes
Add Scrollable interface
This allows ScrollState and LazyListState to be treated as a common type, allowing custom scrolling to be implemented across both types.
This also moves smoothScrollBy to an extension function on Scrollable, taking advantage of this functionality. (I2153b)
LazyVerticalGrid is added. (I17267, b/162213211)
Deprecate LazyColumnFor, LazyRowFor, LazyColumnForIndexed and LazyRowForIndexed. Use LazyColumn and LazyRow instead (I5b48c)
For suspending pointer input APIs, renamed HandlePointerInputScope to AwaitPointerEventScope and handlePointerInput() to awaitPointerEventScope(). (Idf0a1, b/175142755)
LazyListState.layoutInfo was added which exposes the list of sizes and offsets of the currently visible items (If8678, b/170472532)
Removed ExperimentalPointerInput annotation (Ia7a24)
InteractionState support for TextFields has been added. (I61d91)
Add reverseLayout param for LazyColumn/Row. when
true
items will be composed from the bottom to the top andLazyListState.firstVisibleItemIndex == 0
will mean the first item is located at the bottom. (I552ae, b/166589935)verticalArrangement param was added for LazyColumn. horizontalArrangement param was added for LazyRow. Arrangement allows us to add a spacing between items and specify the arrangement of the items when we do not have enough of them to fill the whole minimum size. (Icf79a, b/170394300)
detectMultitouchGestures now uses one callback with combined centroid, pan, zoom and rotate parameters. (Ie6e1c)
Moved ContentDrawScope to ui-graphics module to be with DrawScope. (Iee043, b/173832789)
Bug Fixes
- Lambdas in offset modifiers now return IntOffset rather than Float. (Ic9ee5, b/174137212, b/174146755)
Removed SlotTable, SlotReader and SlotWriter from the public API. These were marked as InternalComposeAPI previously. Now they are internal to the compose module.
CompositionData and CompositionGroup were added as a replacement for the ui-tooling API to use to extract composition information. These are public but are not intended for use outside the ui-tooling API as they provide the raw information the ui-tooling API interprets (I31a9c)
Refactored ShaderBrush to lazily create a shader instance when sizing information of the drawing environment is available. This is useful to define gradients that occupy the full drawing bounds of a composable at composition time, without having to implement custom DrawModifier implementations.
Deprecated gradient function constructor APIs in favor of factory methods on a Gradient object. (I511fc, b/173066799)
Modifier.focusObserver is deprecated. Use Modifier.onFocusChanged or Modifier.onFocusEvent instead (I30f17, b/168511863, b/168511484)
Autofill API is now experimental API and requires opt-in (I0a1ec)
Adding destructuring declarations to create FocusRequester instances (I35d84, b/174817008)
accessibilityLabel has been renamed to contentDescription. accessibilityValue has been renamed to stateDescription. (I250f2)
Introduced several new functions in SelectionRegistrar and also renamed onPositionChange to notifyPositionChange. (Ifbaf7)
AndroidOwner made internal (Ibcad0, b/170296980)
New infiniteRepeatable function for creating an InfiniteRepeatableSpec (I668e5)
The
Applier
interface has changed to simplify building trees bottom-up instead of top-down.The
insert()
method has been renamed toinsertTopDown()
.A new method,
insertBottomUp()
, was added.An applier either inserts nodes into the tree it is editing using
insertTopDown()
orinsertBottomUp()
depending on which performs better.Some trees, such as
LayoutNode
andView
, are much more efficient to build bottom-up than top-down. Prior to this change, a stack of inserts was required to implement bottom-up which needed to be copied to every applier which needed bottom-up construction for performance. With this change anApplier
overridesinsertBottomUp()
to build a tree bottom-up andinsertTopDown()
to build the tree top-down. (Icbdc2)Added painterResource API to handle opaquely loading Painter objects from either rasterized asset formats (like PNGs) or VectorDrawables. Consumers no longer have to determine the type of asset in advance and can call this method to get a Painter object to use in Image composables or painter modifiers. (I2c703, b/173818471)
Added buildAnnotatedString factory function in order to build an AnnotatedString. Deprecated annotatedString builder function. (Idfe0b)

instead. (Iec002) - Changed the
await*TouchSlop()
methods to not detect the pointer down and renamed them to*OrCancellation
. Also removed the need fororientationLock
parameter. (Ie96e1) - Added lint check for composable lambda parameter naming and position, to check for consistency with Compose guidelines.
Also migrated some APIs using
children
as the name for their trailing lambda tocontent
, according to the lint check and guidance. (Iec48e) foundation:foundation-text
apis moved tofoundation:foundation
. The package structure remained the same (Id3eb2)- New multitouch gesture detector, including helpers for detecting rotation, zoom, and panning. (Ic459d)

- Deprecated Ambients named with
Ambient
as their suffix, and replaced them with new properties prefixed with Ambient, following other Ambients and Compose API guidelines. (I33440) - Added Android Typeface wrapper. You can load an Android
Typeface via
typeface
function i.e.typeface(Typeface.DEFAULT)
. Also renamedtypefaceFromFontFamily()
totypeface()
(I52ab7) - Added lint check to check that Modifier factories use
androidx.compose.ui.composed {}
internally, instead of being marked as@Composable
. (I3c4bc) - Added lint check to check that Modifier factory functions are defined as extensions on Modifier, so they can be fluently chained together. (I07981)
- Semantics argument mergeAllDescendants was renamed to mergeDescendants. (Ib6250)
- Time control in tests (TestAnimationClock and its usages) is now experimental (I6ef86, b/171378521)

(I797e2, b/166586426) - Removed
KeyboardOptions.toImeOptions
from public API. (Ic2e45) - The foundation AmbientTextStyle, ProvideTextStyle, and AmbientContentColor have been deprecated. Instead use the new versions available in the Material library. For non-Material applications, you should instead create your own design system specific theming ambients that can be consumed in your own components. (I74acc, b/172067770)
- foundation.Text has been deprecated and replaced with material.Text. For a basic, unopinionated text API that does not consume values from a theme, see androidx.compose.foundation.BasicText. (If64cb)

- The matchHeightConstraintsFirst parameter was added to the aspectRatio modifier, which can be used to specify the modifier to size to height constraints before trying the width correspondents. (Ie7c43, b/155290593)
- The deprecated DpConstraints was removed. (I87884, b/171702471)
Bug Fixes

API Changes
- CoreTextField now supports cursor functionality (Id23aa)
Deprecates contentColor() and currentTextStyle() APIs, and replaces them with AmbientContentColor and AmbientTextStyle ambients respectively. You can access the current value by using
.current

, and androidx.compose.foundation:foundation-text:1.0.0-alpha04
are released. Version 1.0.0-alpha04 contains these commits.
API Changes
- Stack was renamed to Box. The previously existing foundation.Box will be deprecated in favor of the new Box in compose.foundation.layout. The behavior of the new Box is to stack children one on top of another when it has multiple children - this is different from the previous Box, which was behaving similar to a Column. (I94893, b/167680279)
- Box decoration parameters have been deprecated. If you want to have decorations/padding on your box, use Modifiers instead (Modifier.background, Modifier.border, Modifier.padding) (Ibae92, b/167680279)
- Add a new LazyListState class. This allows for observation and control of the scroll position of LazyRow and LazyColumn components. Instances can be created using rememberLazyListState() and passed into the state parameter of the component. Currently, the first visible item and offsets can be observed in this initial version. (Ic7cb7, b/159307669)
- Lazy list position and scroll offset are now saved and restored across Activity recreation (Ie045f, b/166589058)
- Add long click semantics action (I6281b, b/156468846)
- MutatorMutex utility added for keeping a single mutator of shared state over time and cancelling conflicting mutators by priority (I3f975)
- Annotated rootAnimationClockFactory, transitionsEnabled, blinkingCursorEnabled and textInputServiceFactory with @VisibleForTesting, make them internal API and hide their kdoc (I554eb, b/168308412)
- Removed inlineContent parameter from Text with String input. It won't be used because inlineContent must work with AnnotatedString. (Ief403)
- The deprecated custom Arrangement APIs were removed. (Ic576d, b/168297922, b/168297923)
- The
unbounded
parameter was added to wrapContentSize modifiers, which enables measuring the layout element with infinite max constraints. (I77951, b/158559319) - We prevented static imports of contents of layout scopes (e.g. alignWithSiblings in RowScope). The explicit scope alternative should be used instead:
with(RowScope) { Modifier.alignWithSiblings(FirstBaseline) }
. (I216be, b/166760797)
Bug Fixes
- Updated many Graphics APIs
- Updated scale and rotation transformation APIs to consume a single Offset parameter to represent the pivot coordinate instead of separate float parameters for the x/y coordinates in DrawScope and DrawTransform
- Removed Rect.expandToInclude and Rect.join methods
- Updated Radius documentation to say oval in addition to elliptical
- Added documentation to indicate the public constructor for the inline Radius class is not to be called directly but instead Radius objects should be instantiated through their function constructors
- Removed RoundRect APIs to query topRight, bottomRight, bottomCenter, etc.
- Deprecated Rect.shift in favor of Rect.translate
- Removed RoundRect.grow and Rect.shrink APIs
- Renamed RoundRect.outerRect to Rect.boundingRect

- Updated RoundRect constructor to consume Radius properties instead of individual parameters for x/y radius values
- Removed Size APIs that assumed it was a Rectangle with origin at 0,0
- Added a destructing API to Radius
- Migrated various RoundRect extension functions to be properties instead
- (I8f5c7, b/168762961)
- Performance optimizations for LazyColumnFor/LazyRowFor scrolling by not doing unnecessary recompositions during every scroll (I64f65, b/168293643, b/167972292, b/165028371)
- Fixed crash in LazyColumnFor/LazyRowFor after scrolling and then changing items and implemented auto scrolling up when the previously visible item was removed so we don't display empty gaps in the end anymore (I220ab, b/161480164, b/167855468)
- Nesting scrollable in the same direction containers like ScrollableContainer and LazyColumnFor is not allowed anymore. It was never supported and was breaking the fling and all the laziness of composing the items of LazyColumnFor (I6e101)
- Updated many Graphics APIs
- Updated DrawScope APIs with scoped transformation methods to indicate that the transformation is only applied within the callback and removed after the callback is invoked
- Updated clipPath documentation to refer to Path instead of rounded rectangle
- Fixed spacing in documentation for right parameter in clipPath
- Renamed DrawScope.drawCanvas to drawIntoCanvas and removed size parameter
- Renamed dx/dy parameters in inset method to horizontal and vertical

- Removed Rect.join and Rect.expandToInclude
- Created overload for Rect.translate(offset) and deprecated Rect.shift
- (If086a, b/167737376)
- add AccessibilityScrollState to semantics properties. (Ifeda9)
- Make TextRange inline to avoid object creation. (Id034b)
- ParagraphConstraints is removed. Width is directly passed to Paragraph now. (Ica712)

Bug Fixes
- TestUiDispatcher is marked experimental (Iae99d, b/161247083)
Added
ManualFrameClock.hasAwaiters
to see if anything is awaiting a frame from that clock;runWithManualClock
as a replacement forrunBlocking
when running tests that need a ManualFrameClock;TestUiDispatcher.Main
that gives easy access to the main UI dispatcher in your tests.For example:
@Test fun myTest() = runWithManualClock { clock -> // set some compose content withContext(TestUiDispatcher.Main) { clock.advanceClock(1000L) } if (clock.hasAwaiters) { println("The clock has awaiters") } else { println("The clock has no more awaiters") } }

API Changes
- The spacedBy Arrangement was added for Row and Column, to enable positioning layout children with a fixed spacing. The aligned Arrangment was also added, to enable positioning layout children one next to the other and aligned in the Row/Column according to an Alignment. The previous Arrangement.Vertical#arrange and Arrangement.Horizontal#arrange methods were deprecated, and writing custom Arrangements will not be supported in the future. (I6733d, b/161985975)
- Offset has become an inline class (Iaec70)
- Removed onFocusChanged callbacks from TextField. Use Modifier.focusObserver instead. (I51089, b/161297615)
- Modifier.drawBorder has been deprecated. Use Modifier.border instead. Border data class has been replaced by BorderStroke (I4257d, b/158160576)
- VerticalScroller and HorizontalScroller have been removed. Use ScrollableColumn/Row instead. Modifier.drawBackground has been removed. Use Modifier.background (I73b0d, b/163019183)
- Remove marked as deprecated fillMax* modifiers from LazyItemScope as they are making it harder to add such modifiers correctly for items which are not direct children of LazyColumnFor (Ifa78d)
- added LazyColumn/LazyRow implementation as DSL (I93cc6)
- Constraints is now an inline class (I88736)
- Added the ability to size a layout to a fraction of the available space, using the fillMaxWidth, fillMaxHeight and fillMaxSize modifiers. (I945bb, b/161562591)
Bug Fixes
- Added a modifier param to SelectionContainer (I4aada, b/161487952)
- Added mergePolicy lambda to SemanticsPropertyKey. This can be used to define a custom policy for mergeAllDescendants semantics merging. The default policy is to use the parent value if already present, otherwise the child value. (Iaf6c4, b/161979921)
PlacementScope.placeAbsolute()
was renamed toPlacementScope.place()
, and the previousPlacementScope.place()
was renamed toPlacementScope.placeRelative()
. As a result, thePlacementScope.place()
method will not automatically mirror the position in right-to-left contexts anymore. If this is desired, usePlacementScope.placeRelative()
instead. (I873ac, b/162916675)- Removed deprecated FilledTextField component. Please use TextField instead to get the Material Design implementation of the Filled text field. (I5e889)
- Added backgroundColor parameter to LinearProgressIndicator and removed internal padding from CircularProgressIndicator. Added new ProgressIndicatorConstants.DefaultProgressAnimationSpec which can be used as the default AnimationSpec when animating progress between values (If38b5, b/161809914, b/161804677)
- The
state { ... }
composable is now deprecated in favor of explicit calls toremember { mutableStateOf(...) }
for clarity. This reduces the overall API surface and number of concepts for state management, and matches theby mutableStateOf()
pattern for class property delegation. (Ia5727) - Renamed RRect to RoundRect to better fit compose naming patterns Created similar function constructors to RRect and deprecated RRect function constructors (I5d325)
- Removed onChildPositioned and OnChildPositionedModifier. Developers should use onPositioned and OnPositionedModifier on the child layout instead. (I4522e, b/162109766)
- IntSize is now an inline class (I2bf42)
- LongPress the Blank Area to Edit. (Ib1e5b)
- Hide FloatingToolbar After Tapping on the Text. (If4525)

API Changes
- LazyItemScope was added for itemContent param of Lazy lists. It provides modifiers to fill the parent max size which solves the use case when the item should fill the viewport and the regular Modifier.fillMaxSize() doesn't work as the item is measured with infinity constraints. (Ibd3b2, b/162248854)
- Move dialog to ui (I47fa6)
- Added LazyColumnForIndexed/LazyRowForIndexed - versions of LazyColumnFor/LazyRowFor which provides both index and item in the itemCallback. It is useful when in addition to a current item you need to know a current index. (I65ff3)
- Modifier.deternimateProgress has been renamed to Modifier.progressSemantics (I9c0b4)
- LazyColumnItems was renamed to LazyColumnFor. LazyRowItems was renamed to LazyRowFor (I84f84)
- Add some Marks/Annotations for best practice reason. (I66b20)
- foundation.shape.corner package were flatten to foundation.share (I46491, b/161887429)
- Added сrossaxis gravity param for LazyRowItems/LazyColumnItems. LazyRowItems/LazyColumnItems now support wrap content behaviour. (Ib39fc)
- ZoomableState has been renamed to ZoomableController. Custom curve support has been added for smoothScale.
enabled
andonZoomStarted
functionality has been added (If8b8f) - Material FilledTextField was renamed to TextField and foundational TextField was renamed to BaseTextField to make simplest desired API easy to discover and use (Ia6242, b/155482676)
- Previously deprecated AdapterList has been removed. Use LazyColumnItems instead (I12b9b)
- Modifier.drawBackground has been renamed to Modifier.background (I13677)
- The old ConstraintLayout DSL was removed. ConstraintSet2 has been renamed to ConstraintSet. (If58d1, b/162450908)
- Added Modifier.absoluteOffset() and Modifier.absoluteOffsetPx(). Unlike offset modifiers, absolute offset modifiers will not auto-mirror in right-to-left context (I3aa21)
Row
andColumn
are now inline function significantly reducing the overhead of using them. (I75c10)
Bug Fixes
- Address broad API fixes (I077bc)
- Remove unused OffsetBase interface
- Align Offset and IntOffset classes to have a consistent API surface
- Rename IntOffset.Origin to IntOffset.Zero to be consistent with Offset API
- Moved nativeCanvas method off of Canvas interface to support consumers to create their own Canvas instances
- Created stub EmptyCanvas class to refactor DrawScope to be a non-null parameter instead of lateinit and ensure non-nullability of the field
- Renamed ClipOp enums to be Pascal Case
- Renamed FilterQuality enums to be Pascal Case
- Renamed StrokeJoin enums to be Pascal Case
- Renamed PointMode enums to be Pascal Case
- Renamed PaintingStyle enums to be Pascal Case
- Renamed PathFillType enums to be Pascal Case

- Updated VertexMode enum to be PascalCase
- Updated DrawScope selectPaint method to conditionally overwrite stroke parameters on the paint if they have changed
- Updated Size to add destructuring API, rename UnspecifiedSize to Unspecified and removed unused methods
Added MonotonicFrameAnimationClock that enables you to use a MonotonicFrameClock as an AnimationClockObservable to bridge the gap between the new coroutines based clocks and APIs that still use the old callback based clocks.
The MonotonicFrameClock equivalent of ManualAnimationClock is now ManualFrameClock. (I111c7, b/161247083)
Removed
SemanticsNodeInteraction.performPartialGesture
. UseSemanticsNodeInteraction.performGesture
instead. (Id9b62)Renamed
SemanticsNodeInteraction.getBoundsInRoot()
toSemanticsNodeInteraction.getUnclippedBoundsInRoot()
(Icafdf, b/161336532)The APIs for right-to-left support has been updated. LayoutDirectionAmbient has been added, which can be used to read and change the layout direction. Modifier.rtl and Modifier.ltr have been removed. (I080b3)
Modifier.plus has been deprecated, use Modifier.then instead. 'Then' has a stronger signal of ordering, while also prohibits to type
Modifier.padding().background() + anotherModifier
, which breaks the chain and harder to read (Iedd58, b/161529964)Added
isFocused()
andisNotFocused()
SemanticsMatcher. (I0b760)RemeasurementModifier was added. It allows users to synchronously remeasure the layout. In general, you never need it as remeasure/relayout is happening automatically, but we use it inside LazyColumnItems during the scroll. (I5f331, b/160791058)
isSystemInDarkTheme now always considers the system-wide dark theme setting, and ignores power saving status before Q, following latest guidance. (I0c10c)

Renamed AndroidComposeTestRule to createAndroidComposeRule. (I70aaf)
Add accessibility action to get TextLayoutResult (I9d6e6)
Version 0.1.0-dev15
July 22, 2020
androidx.compose.foundation:foundation:0.1.0-dev15
, androidx.compose.foundation:foundation-layout:0.1.0-dev15
, and androidx.compose.foundation:foundation-text:0.1.0-dev15
are released. Version 0.1.0-dev15 contains these commits.
To use the 0.1.0-dev15
version of Compose, you will need to:
Dependencies Update
- To use the
0.1.0-dev15
version of Compose, you will need to update your dependencies according to the new code snippets shown above in Declaring dependencies.
API Changes
- Similarly to the new param in ScrollableColumn/ScrollableRow LazyColumnItems/LazyRowItems now also have contentPadding param which allows to add a padding for the content after it has been clipped, which is not possible via just a modifier param. It also allows to add a spacing only before first item/after last item. (Ibc24e)
- onFocusChange callback in text fields renamed to onFocusChanged (Ida4a1)
- VerticalScroller and HoriziontalScroller have been deprecated. Use ScrollableColumn and ScrollableRow for build-in experience with Column/Row behaviour and parameters, or Modifier.verticalScroll and Modifier.horizontalScroll on your own element. Similarly, ScrollerPosition has been deprecated in favor of ScrollState' (I400ce, b/157225838, b/149460415, b/154105299)
- Modifier.draggable and Modifier.scrollable APIs were reworked. DragDirection was removed in favor of Orientation. State required for scrollable has beed simplified. ScrollableState has been renamed to ScrollableController (Iab63c, b/149460415)
- Single-value semantics properties now use a calling style.
For example, 'semantics { hidden = true }' is now written as:
semantics { hidden() }
. (Ic1afd, b/145951226, b/145955412) - Corner sizes used by RoundedCornerShape and CutCornerShape can now be larger than 50% (Id2340, b/160400213)
- Changed the default ContentScale parameter for the Image composable from Inside to Fit. This was done in order to get behavior to scale up the underlying Painter if the layout size is larger than the intrinsic size of the painter while maintaining the aspect ratio. This behavior better matches expectations for providing fixed sizes to the Image while not affecting the default behavior if only the intrinsic size is used to compute the size of the composable. (I40ae3, b/159838006)
- Use AnimationSpec instead of AnimationBuilder in the top level APIs to clarify the concept of static animation specification -Improve the transition DSL by removing the lambda requirement for creating AnimationSpecs such as tween, spring. They instead take constructor params directly. -Improve the overall ease of use of AnimationSpec opening up constructors instead of relying on builders -Change the duration and delay for KeyFrames and Tween to Int. This eliminates unnecessary type casts and method overloading (for supporting both Long and Int). (Ica0b4)
- Clickable was removed. Use Modifier.clickable (I84bdf)
- Added LazyRowItems - Horizontally scrolling analogue of LazyColumnItems (Ibbcf7)
- Introduced low level stateless animation APIs. These APIs (I63bf7)
- androidx.ui.foundation.TextFieldValue and androidx.ui.input.EditorValue is deprecated. TextField, FilledTextField and CoreTextField composables that uses that type is also deprecated. Please use androidx.ui.input.TextFieldValue instead (I4066d, b/155211005)
- Replaced usage of IntPx with Int. Replaced IntPxPosition with IntOffset. Replaced IntPxSize with IntSize. (Ib7b44)
- androidx.ui.foundation.shape.RectangleShape removed; use androidx.ui.graphics.RectangleShape (I94939, b/154507984)
- In order to consolidate the number of classes used to represent sizing information, standardize on usage of the Size class instead of PxSize. This provides the benefits of an inline class to leverage a long to pack 2 float values to represent width and height represented as floats. (Ic0191)
- In order to consolidate the number of classes used to represent positioning information, standardize on usage of the Offset class instead of PxPosition. This provides the benefits of an inline class to leverage a long to pack 2 float values to represent x and y offsets represented as floats. (I3ad98)
- Added Modifier.zoomable for pinch-to-zoom functionality (Id5d63)
- Toggleable component has been deprecated. Use Modifier.toggleable instead (I35220, b/157642842)
- MutuallyExclusiveSetItem has been deprecated. Use Modifier.selectable instead. (I02b47, b/157642842)
- TestTag is now deprecated. Use Modifier.testTag instead. (If5110, b/157173105)
- Adds fontWeight parameter to Text, which was accidentally not added previously (I56937)
- Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters (I19d02)
- VerticalScroller now provides Column out of the box. HorizontalScroller now provides Row out of the box. (Ieca5d, b/157020670)
- Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters (Iede0b)
- Modifier.indication has been added to foundation package. Use it to show press/drag/other indication on your custom interactable elements (I8425f, b/155287131)
- VerticalScroller and HorizontalScroller now support reversed scrolling is isReversed is set on ScrollerPosition (I953bd)
- Support adding composables into text layout. (I1373c)
- Consolidated CanvasScope implementations so there is now just DrawScope and ContentDrawScope Renamed CanvasScope to DrawScope. Updated DrawScope to implement Density interface and provide LayoutDirection Deleted DrawScope subclass in ContentDrawScope Painter and PainterModifier have been updated to no longer maintain an RTL property themselves as DrawScope provides this already without manually providing it (I1798e)
- Removed deprecated DrawBackground API in favor of drawBackground extension APIs on Modifier. Refactored color, brush and paint drawBackground implementations to reduce code paths as well as remove requirement for Modifier to be created as part of composition. (I0343a)
- Updated higher level compose APIs that expose a Canvas to expose CanvasScope instead. This removes the need for consumers to maintain their own Paint objects. For consumers that still require access to a Canvas they can use the drawCanvas extension method which provides a callback to issue drawing commands with the underlying Canvas. (I80afd)
- HorizontalScroller and VerticalScroller not restores their scroll position using saved instance state. (Ia0fae, b/155075048)
- FocusManagerAmbient is removed. Use FocusModifier.requestFocus to obtain focus. (Ic4826)
- Table layout was removed temporarily until we will make it available again with a refreshed API. (Id88a7)
Created CanvasScope API that wraps a Canvas object to expose a stateless, declarative drawing API surface. Transformations are contained within their own receiver scope and sizing information is also scoped to corresponding inset bounds. It does not require a consumer to maintain its own Paint state object for configuring drawing operations.
Added CanvasScopeSample as well as updated the demo app to include a declarative graphics demo (Ifd86d)
ColoredRect has been removed. User Box with drawBackground modifier instead (I983c7, b/152753731)
Add cursor color customisation to the TextField (I6e33f)
Now it is possible to hide/show software keyboard by using SoftwareKeyboardController which is delivered by onTextInputStarted callback (I8dc44, b/151860051)
TextFieldValue used with TextField can now be survive activity recreation when used like this:
var text by savedInstanceState(saver = TextFieldValue.Saver) { TextFieldValue() }
(I5c3ce, b/155075724)Adds commonly used parameters to Text(). If you are currently creating a local text style to pass a small number of these parameters, such as
Text(style = TextStyle(textAlign = TextAlign.Center))
, you can now just provide the parameters directly:Text(textAlign = TextAlign.Center)
(I82768)Replaced CoreTextField/TextField focusIdentifier parameter with FocusNode in order to integrate with focus subsystem. (I7ea48)
TextField update - in horizontal dimension it will occupy all available space granted to it (Ib08df, b/154638552)
Added InteractionState and Interaction, making it easier to build components that react to UI state changes such as press, and drag (Icfe25, b/152525426)
RectangleShape moved from androidx.ui.foundation.shape.* to androidx.ui.graphics.* (Ia74d5, b/154507984)
Replaced all nullable Color uses in API with non-nullable and use Color.Unset instead of null (Iabaa7)
TextField API update - merged onFocus and onBlur callbacks into a single onFocusChange(Boolean) callback with parameter (I66cd3)
Renamed ScaleFit to ContentScale Moved ContentScale from ui-graphics to ui-core module to live in the same module as the Alignment API. Renamed FillMaxDimension to Crop Renamed FillMinDimension to Fit Renamed Fit to Inside to better match ImageView.ScaleType equivalents Added documentation indicating that the combination of Crop and Alignment.Center achieves the same result as ImageView.ScaleType.CENTER_CROP and Fit used with Alignment.Center achieves the same result as ImageView.ScaleType.FIT_CENTER Inside used with Alignment.Center achieves the same result as ImageView.ScaleType.CENTER_INSIDE (I45f09, b/152842521)
Removes ProvideContentColor, instead just use ContentColorAmbient directly with
Providers
(Iee942)Adds color parameter to text, allowing overriding the color of the text style without needing to manually merge with the style provided in a theme. (I41a66)
Improve DrawModifier API:
- Made the receiver scope for draw() ContentDrawScope
- Removed all parameters on draw()
- DrawScope has same interface as former CanvasScope
- ContentDrawScope has drawContent() method (Ibaced, b/152919067)
ColoredRect has been deprecated. Use
Box(Modifier.preferredSize(width, height).drawBackground(color))
instead. (I499fa, b/152753731)Shape theming system is updated according to the Material design specification. Now you can provide small, medium and large shapes to be used by most of the components (Ifb4d1)
Replaced Modifier plus operator with factory extension functions (I225e4)
Draggable has been moved to modifier (Id9b16, b/151959544)
Moved
Text
to androidx.ui.foundation package, from androidx.ui.core. (I87ce5)add
enabled
param to Checkbox, Switch and Toggleable (I41c16)Ripple is now a Modifier. While Clickable is not yet converted the recommended usage is
Clickable(onClick = { ... }, modifier = ripple())
(Ie5200, b/151331852, b/150060763)Added VectorPainter API to replace existing subcomposition API for vector graphics. Result of subcomposition is a VectorPainter object instead of a DrawModifier. Deprecated previous DrawVector composables in favor of VectorPainter.
Renamed
Image(Painter)
API toPaintBox(Painter)
Created Vector composable that behaves like the Image composable except with a VectorAsset instead of an ImageAsset (I9af9a, b/149030271)Created Image composable to handle sizing/layout in addition to drawing a given ImageAsset to the screen. This composable also supports drawing any arbitrary Painter instance respecting its intrinsic size as well as supporting a given fixed size or minimum size (Ibcc8f)
Button, FloatingActionButton and Clickable now have a separate
enabled
param. Some of the params on Button were renamed or reordered. (I54b5a)Renamed Image to ImageAsset to better differentiate the difference between the Image data and the upcoming Image composable used to participate in layout and draw content.
Created extension method on android.graphics.Bitmap,
Bitmap.asImageAsset()
, to create an instance of an ImageAsset useful for combining traditional Android application development with the compose framework. (Id5bbd)DrawImage composable was removed. Use ImagePainter to draw image on existing layout, or SimpleImage to introduce Image that takes space (I595e1, b/149827027)
Stack component supports right-to-left directionality (Ic9e00)
Added Icon, IconButton and IconToggleButton, removing AppBarIcon. You can directly replace existing usages of AppBarIcon with IconButton, and they will now have the correct touch target. See the samples for usage information, and see Icons for the provided Material Icons you can use directly with these components. (I96849)
DrawShape composable was removed. Use DrawBackground modifier instead. (I7ceb2)
Added AdapterList, a scrolling list component that only composes and lays out the visible items. Currently known issues include that it is vertical-only and does not fully handle all cases of changes to its children. (Ib351b)
Scrollable component has been added, which allows creation of custom Scrollers/Lists (I5fd37)
Renamed background to DrawBackground and make it to be memorized by default (Ia0bd3)
Add paddings, border, shape and background param to Box (I05027, b/148147281)

has been added (I94985, b/157133803)Removed deprecated RowAlign, ColumnAlign in Row and Column. (If60d4, b/155858731)
Removed deprecated LayoutTag(), please use Modifier.tag() instead. Removed deprecated Modifier.matchParent(), please use Modifier.matchParentSize() instead. (If8044)
Added the offsetPx layout modifier, which can be used to define (dynamic) offsets in px. (I5af57)
AlignmentLineOffset composable is deprecated, please use relativePaddingFrom() modifier instead. CenterAlignmentLine composable is removed. (I60107)
Added defaultMinSizeConstraints layout modifier, which sets size constraints to the wrapped layout only when the incoming corresponding constraints are unspecified (0 for min constraints and infinity for max constraints). (I311ea, b/150460257)
Container has been removed. Use Box instead (Ibbc2b, b/151407926)
Removed deprecated LayoutWidth/Height/Size modifiers. (Ib0bc1)
Added default parameter values for the offset modifier. (I37f06)

Removed deprecated LayoutAspectRatio modifier. (I65a74)
Removed deprecated LayoutAlign modifiers. (I10877)
Fixed a bug in the width and height modifiers that was causing the wrapped layout to be measured with no opposite axis constraints. (I210b8, b/154797971)
Added verticalGravity and horizontalGravity parameters to Row and Column, respectively. (I7dc5a)
Updated wrapContentWidth and wrapContentHeight to expect vertical or horizontal Alignment rather than any Alignment. The gravity modifier was updated to accept vertical or horizontal Alignment. Row, Column and Stack were updated to support custom continuous Alignments. (Ib0728)
Made Alignment instantiable with arbitrary values. Added 1D Alignments. (Ia0c05)
Renamed EdgeInsets to InnerPadding. Renamed innerPadding parameter of Material Buttons to paddding. (I66165)
alignToSiblings now accepts a Measured instead of Placeable. (I5788d)
Added modifiers for sizing to intrinsic measurements and deprecated the components serving this purpose. (I8295d)
Added support for customizing dimensions of children of ConstraintLayout (Idb1a5)
Removed deprecated Wrap and Center composables. (I29e23)
Added LayoutModifier2, a new API for defining layout modifiers; deprecated LayoutModifier (If32ac)

Bug Fixes
- FocusModifier is deprecated in favor of Modifier.focus, Modifier.focusRequester, Modifier.focusObserver. FocusState and FocusDetailedState are deprecated in favor of FocusState2 (I46919, b/160822875, b/160922136)
runOnIdleCompose
renamed torunOnIdle
(I83607)- Several testing APIs were renamed to be more intuitive. All findXYZ APIs were renamed to onNodeXYZ. All doXYZ APIs were renamed to performXYZ. (I7f164)
- Removes previously deprecated Modifier.ripple. Clickable now uses ripple as the default indication (if you have a MaterialTheme {} set in your application) so in most cases you can just use clickable and get ripple indication for free. If you need to customize the color / size / bounded parameter for the ripple, you can manually create a RippleIndication and pass it to clickable as the indication parameter. (I663b2, b/155375067)
- Removed obsolete size testing APIs. (Iba0a0)
- Made LayoutNode experimental API (I4f2e9)
- Version 1 of scroll orientation locking is implemented across Compose. (I1ce7a, b/150289741)
- Popups, Dialogs and Menus are now inheriting the contextual MaterialTheme (Ia3665, b/156527485)

- Add AbsoluteArrangement - allows for arrangement of the children inside the Row without automatic mirroring in RTL (I3a1df)
- @Untracked annotation has been deprecated. Replace with @ComposableContract(tracked=false) (Id211e)
- Prior to this change, the compose compiler plugin would non-trivially intercept calls to constructors inside of a @Composable function if there was an (I5205a, b/158123804)
- Add
viewModel()
composable which allows to create or get already created ViewModel similarly to how it works in Activity or Fragment (I5fdd1) Refactored Radius class to be an inline class. Removed companion creation methods in favor of function constructor with default parameter to have the radius along the y-axis match that of the mandatory x-axis radius parameter.
Updated DrawScope.drawRoundRect to consume a single Radius parameter instead of 2 separate float values for the radius along the x and y axis (I46d1b)
Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters. Deleted Px class in its entirety (I3ff33)
Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters (I086f4)
Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters (Id3434)

TextField's cursor has a blinking animation (Id10a7)
Partial gestures no longer require passing around of a GestureToken (Id7ae5)
Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters (I57bff)
Modifier.semantics has been undeprecated to allow usages for high level components. (I4cfdc)
Rename AnnotatedString.Builder.addAnnotationString to addStringAnnotation. (I5059e)
Updated Alignment API and added support for absolute alignment (which does not auto-mirror in Rtl context) (I38cd3)
Layout and LayoutModifier children can be measured with a different layout direction. (Ibd731)
Introduce additional optional rect parameter to ImagePainter to support drawing a subsection of underlying ImageAsset (I0ea9e)
Fixed a crash in AdapterList when removing items (Ic64b0, b/153195921)
We changed how we measure the first layout you put inside activity.setContent { } block. Previously it was forced to fill the whole activity screen, and now it behaves as if you put your layout inside a Stack: it can be smaller than a screen and will be positioned in the top left screen. If you want the old behaviour you can apply Modifier.fillMaxSize() for your layout. (Ie88a7, b/153453714)
ui-text-compose module is renamed as ui-text. ui-text now contains CoreText and CoreTextField composables (Ib7d47)
ui-text module is renamed as ui-text-core (I57dec)
Moved ui-framework/CoreText, CoreTextField composables under ui-text-compose. You might want to include ui-text-compose in your project. (I32042)
runOnIdleCompose
andrunOnUiThread
are now global functions instead of methods on ComposeTestRule. (Icbe8f)[Mutable]State property delegate operators moved to extensions to support Kotlin 1.4 property delegate optimizations. Callers must add imports to continue using
by state { ... }
orby mutableStateOf(...)
. (I5312c)DrawLayerModifier and drawLayer() now default clipToBounds and clipToOutline to false. (I0eb8b, b/152810850)
Renamed LayoutResult to MeasureResult. (Id8c68)
Deprecated Center composable. It should be replaced either with the LayoutSize.Fill + LayoutAlign.Center modifier, or with one of the Box or Stack composables with suitable modifiers applied (Idf5e0)
Renamed LayoutFlexible to LayoutWeight. Renamed tight parameter to fill. (If4738)
DrawVector has been changed from a regular composable function to returning a Modifier drawVector() that will draw the vector as a background to a layout. (I7b8e0)
Replace composable function Clip with modifier drawClip(). DrawClipToBounds is a convenient modifier to use when you only need to clip to the layer bounds with a rectangle shape. (If28eb)
Replaced DrawShadow composable function with drawShadow() modifier. Shadows are now drawn as part of LayerModifier. (I0317a)
androidx.compose.ViewComposer has been moved to androidx.ui.node.UiComposer androidx.compose.Emittable has been removed. It was redundant with ComponentNode. androidx.compose.ViewAdapters has been removed. They are no longer a supported use case. Compose.composeInto has been deprecated. Use
setContent
orsetViewContent
instead. Compose.disposeComposition has been deprecated. Use thedispose
method on theComposition
returned bysetContent
instead. androidx.compose.Compose.subcomposeInto has moved to androidx.ui.core.subcomposeInto ComponentNode#emitInsertAt has been renamed to ComponentNode#insertAt ComponentNode#emitRemoveAt has been renamed to ComponentNode#removeAt ComponentNode#emitMode has been renamed to ComponentNode#move (Idef00)Deprecated Wrap composable. It can be replaced either with the LayoutAlign modifier or with the Stack composable (Ib237f)
Made the layout direction be propagated from parent layout node to children. Added layout direction modifier. (I3d955)
Rename Painter.toModifier to Painter.asModifier as the newly created Modifier has a reference to the original Painter that can be shared across multiple Modifier instances (I7195b)
Support right-to-left direction in LayoutPadding modifier (I9e8da)
Density and DensityScope were merged into one interface. Instead of ambientDensity() you can now use DensityAmbient.current. Instead of withDensity(density) just with(density) (I11cb1)
Removed ValueHolder class. Restructured AnimatedValue, AnimatedFloat classes to make the animation value field abstract so that subclasses can watch the value update.
- Added model classes for AnimatedValue, AnimatedFloat, etc.
- Added a new set of light-weight @Composable API for animating between values.

Breaking changes to the ambients API. See log and
Ambient<T>
documentation for details (I4c7ee, b/143769776)Alignment line Int positions returned from Placeable#get(AlignmentLine) are now non-null. If the queried alignment line is missing, AlignmentLine.Unspecified will be returned. (I896c5, b/158134875)
Fixed a ConstraintLayout bug causing a crash on recompositions. (Ibee5a, b/158164341)
WithConstraints trailing lambda API has been changed. Now instead of two params it has a receiver scope which in addition to constraints and layoutDirection provides minWidth, maxWidth, minHeight and maxHeight properties in Dp (I91b9a, b/149979702)
Renamed LayoutModifier2 to LayoutModifier. (Id29f3)
Intrinsic measurements functions in Layout and LayoutModifier2 have an IntrinsicMeasureScope receiver now which provides intrinsics query API with implicitly propagated layout direction. (Id9945)
LayoutDirectionAmbient is deprecated. To read the layout direction defined by the locale, use localeLayoutDirection on ConfigurationAmbient (I851b1)
Added positionInParent and boundsInParent for LayoutCoordinates. (Icacdd, b/152735784)
ParentData composable is deprecated. You should either create a modifier which implements ParentDataModifier interface, or use LayoutTag modifier if you simply need to tag layout children to recognize them inside the measure block. (I51368, b/150953183)
Add OnPositionedModifier and OnChildPositionedModifier to replace OnPositioned and OnChildPositioned composable functions. (I2ec8f)
Disallow negative padding in LayoutPadding. LayoutOffset should be used instead for negative position offsets. (Ifb5b1)
WithConstraints got LayoutDirection parameter (I6d6f7)
Updated the
ComposeFlags.COMPOSER_PARAM
flag to betrue
, which will change the code generation strategy for the compose plugin. At a high level, this causes @Composable functions to be generated with an additional synthetic parameter, which is passed through to subsequent @Composable calls in order for the runtime to properly manage execution. This is a significant binary breaking change, however, should preserve source-level compatibility in all sanctioned usage of compose. (I7971c)Changed LayoutCoordinates to make providedAlignmentLines a Set instead of a Map and have LayoutCoordinates implement the get() operator instead for retrieving a value. This makes it easier for modifiers to modify one or more value of the set without creating a new collection for each modifier. (I0245a)
LayoutCoordinates no longer has a position property. The position property does not make sense when considering LayoutModifiers, rotation, or scaling. Instead, developers should use parentCoordinates and childToLocal() to calculate the transform from one LayoutCoordinate to another.
LayoutCoordinates uses IntPxSize for the size property instead of PxSize. Layouts use integer pixel sizes for layouts, so all layout sizes should use integers and not floating point values. (I9367b)
Improvements to the API surface of Constraints (I0fd15)
Added TextDirection.Content (I48f36)
Ajdust the Toolbar Menu to show copy, cut, paste properly. (Id3955)
Add FloatingToolbar for TextField Selection. (Ie8b07)
TextDirectionAlgorithm is renamed as TextDirection (I75ce8)
TextDirection is renamed as ResolvedTextDirection (I3ff38)
Add HapticFeedback to TextField Selection. (I58050)
Add Copy, Cut, and Paste methods to TextField Selection. (Idb70b)
TestTag and Semantics have been deleted. Use Modifier.testTag and Modifier.semantics instead (I15ff0, b/158841414)
Changed the package name for Locale and LocaleList from androidx.ui.text to androidx.ui.intl (I8132c)
API change:
AnnotatedString(builder: Builder)
is renamed toannotatedString(builder: Builder)
. (Ia6377)API change:
AnnotatedString.Item
is renamed toAnnotatedString.Range
. (I2d44d)Add Toolbar for text related operations. (I49d53)
New LifecycleOwnerAmbient is now available. Now an Activity you are using with Compose UI should extend androidx.activity.ComponentActivity (or AppCompatActivity). setContent on android.app.Activity is now deprecated (Idb25a, b/153141084)
ui-android-text package name (androidx.text) replaced with androidx.ui.text.platform in order to align with androidx policy. (I42711)
