androidx.compose.animation:animation-*:1.7.0
is released.
Important changes since 1.6.0
Important changes in version 1.7.0 are covered in this blogpost.
New Shared Element Transition APIs
- New shared element transition APIs await your usage and feedback. These new experimental APIs enable tagging layouts as shared across layout tree using the provided modifiers, producing smoothly changing bounds when one set of shared content exits and the other set enters. (Icb0b9)
- New
scaleInSharedContentToBounds
andscaleOutSharedContentToBounds
to scale content insharedBounds
(I731c1) - Experimental
SharedTransitionScope
is now an interface rather than a class. (Iaf856) - New
resizeModes
(ScaleToBounds
andRemeasureToBounds
) forsharedBounds
to choose between scaling and remeasure. The previousscaleIn/OutSharedContentToBounds
APIs are now deprecated. (I0d41a)
Improvements to existing APIs:
- New
Modifier.animateContentSize
that takes an additional parameter for custom content alignment. (I5623a, b/269803907) - New Experimental
DeferredTargetAnimation
for animating size, position, or any other target that is unknown during instantiation. (I60745) SeekableTransitionState
replacessnapTo()
withseekTo()
, and adds asnapTo()
that immediately changes the state to a destination state without any kind of animation.- You may now pass a
periodicBias
value (Float) tokeyframesWithSpline
, this will make it so that the initial and final velocity of the spline are equal. Useful for repeatable animations using splines. The bias indicates how much each velocity (initial and final) gets modified to achieve periodicity. (Ic1e6c, b/292114811)
The following APIs have become stable or been removed:
AnimatedVisibilityScope.transition
is now a stable API.Modifier.animateEnterExit(..)
has also been made stable. (I6c1d1)ApproachLayoutModifierNode
andModifier.approachLayout
are now stable, with newisMeasurementApproachInProgress()
andisPlacementApproachInProgress()
to replace the oldisMeasurementApproachComplete()
andisPlacementApproachComplete()
respectively.- Removed deprecated
intermediateLayout
modifier. (I3e91c) LookaheadScope
APIs have been made stable. (I21507)

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) - New param in
AnimatedContent
for tooling label (Iebe2d)

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

AnimatedContent
Composable. It manages its content change using customizableContentTransform
as new target content enters and initial content leaves. Different combination of enter and exit transitions can be used to produce a customized look and feel. As a part of the content transform,AnimatedContent
automatically animates its size to match the incoming content. (I2c3df) - Removed
ManualFrameClock
. If you need to control animations, usecomposeTestRule.mainClock
instead. (I3c3e8, b/189951065)
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.

, 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)

API Changes
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)
- smoothScrollBy and scrollBy methods' packages changed to
androidx.compose.foundation.gestures.*
(I3f7c1, 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)
- 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)
- 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) - animate, animatedValue, AnimatedValue APIs have been removed (If27bc, b/177457083)
- AnimationEndReason.Interrupted is removed. CancellationException will be throws if animation is interrupted. (I2cbbc, b/179695417)
- TargetAnimation API has been removed. (If47d1, b/177457083)
Version 1.0.0-alpha12
February 10, 2021
androidx.compose.animation:animation:1.0.0-alpha12
and androidx.compose.animation:animation-core: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)- Bounds has been renamed to DpRect (I4b32a)
- Unified the param name for AnimationSpec to animationSpec across the animation system. Also constrain the Enter/ExitTransition to accept FiniteAnimationSpec. (Ie47c5, b/177457083)
- Animatable.snapTo and Animatable.stop are now suspend functions (If4288)
- 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 hasstateSaver
parameter. The usage will look like this:val holder = rememberSaveable(stateSaver = HolderSaver) { mutableStateOf(Holder(0)) }
(Ib4c26, b/177338004) - Updated Crossfade's method signature to be more consistent with the rest of the animation system. (Ib05ed, b/177457083)
- 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)
- Updated Modifier.animateContentSize API to be consistent with the rest of the animation system. (I0bf75, b/177457083)
- AnimatedValue/Float is now deprecated. Please use Animatable instead. (I71345, b/177457083)
- tapGestureFilter, doubleTapGestureFilter, longPressGestureFilter and pressIndicaitonGestureFilter have been deprecated. Use Modifier.clickable or Modifier.pointerInput with detectTapGestures function instead. (I6baf9, b/175294473)
- 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) - Destructuring and copy() methods have been removed from several classes where they were rarely used. (I26702, b/178659281)
- Playtime in animation is now unfiied to nanoseconds (If776a)
- 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)
- Added
Animation.isInfinite
andVectorizedAnimationSpec.isInfinite
that signal if an animation is infinite or not. This can be used in implementations of animations to have special handling of such animations. For example, a special "time remaining" message can be shown, or during tests the animation can be cancelled to prevent waiting for idleness indefinitely. (Iebb05, b/151940543) - Use Long instead of Uptime as animation time type (Ie3aa7, b/177420019)
Version 1.0.0-alpha11
January 28, 2021
androidx.compose.animation:animation:1.0.0-alpha11
and androidx.compose.animation:animation-core:1.0.0-alpha11
are released. Version 1.0.0-alpha11 contains these commits.
API Changes
- TransitionDefinition-based Transition has been deprecated (I0ac57)
- A label field is added for Transition and child animations to be displayed in tools (I619fb)
- animateAsState is now animateFooAsState, where Foo is the type of the variable being animated. e.g. Float, Dp, Offset, etc (Ie7e25)
- New InfiniteTransition that runs any number of child animations. (I1da81)
- Changes Material stateful parameter interfaces to have @Composable functions that return
State<T>
. Adds Animatable.asState() to make it easier to convert an Animatable to a State. Also changes animateElevation to be a suspend extension on Animatable. (If613c)
Bug Fixes
- onCommit, onDispose, and onActive have been deprecated in favor of SideEffect and DisposableEffect APIs (If760e)
- Initial State in updateTransition is now supported (Ifd51d)
- Content description parameter has been added to the Image and Icon. It is used to provide description to the accessibility services (I2ac4c)
- invalidate and compositionReference() are now deprecated in favor of currentRecomposeScope and rememberCompositionReference respectively. (I583a8)
- 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)
- clickable, toggleable and selectable can be created outside of composition now (I0a130, b/172938345, b/175294473)
- Easing has been changed to a functional interface (Ib14e5)
- 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) - 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)
Version 1.0.0-alpha10
January 13, 2021
androidx.compose.animation:animation:1.0.0-alpha10
and androidx.compose.animation:animation-core:1.0.0-alpha10
are released. Version 1.0.0-alpha10 contains these commits.
API Changes
- Modified Velocity to have component parts and mathematical operations. (Ib0447)
- Renamed
@ExperimentalTesting
to@ExperimentalTestApi
to be consistent with similar experimental api annotations (Ia4502, b/171464963) - Renamed Position to DpOffset and removed getDistance() (Ib2dfd)
- Removed Any.identityHashCode() public api (I025d7)
Bug Fixes
- New coroutine-based API
Animatable
that ensures mutual exclusiveness among its animations. New DecayAnimationSpec to support multi-dimensional decay animation (I820f2, b/168014930) 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)
Version 1.0.0-alpha09

API Changes
- Moved Dp.VectorConverter, Position.VectorConverter, etc to animation-core, and deprecated the old VectorConveters (If0c4b)
- Introduced a whole new set of Transition APIs with improved ease of use, and support for dynamically added animations, and dynamically calculated animation targets. This APIs are marked experimental for easy differentiation from the TransitionDefinition-based API. (Ia7fe3)
Bug Fixes
- Lambdas in offset modifiers now return IntOffset rather than Float. (Ic9ee5, b/174137212, b/174146755)
- 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)
- New infiniteRepeatable function for creating an InfiniteRepeatableSpec (I668e5)
- Removed ExperimentalPointerInput annotation (Ia7a24)

are released. Version 1.0.0-alpha08 contains these commits.
API Changes
- 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) - Previously Deprecated APIs were removed:
Modifier.onPositioned
was removed, useModifier.onGloballyPositioned
.Modifier.onDraw
was removed, useModifier.onDrawBehind
.Modifier.plus

- Added Modifier.scale/rotate
APIs as conveniences for drawLayer.
- Renamed Modifier.drawOpacity to Modifier.alpha
- Renamed Modifier.drawShadow to Modifier.shadow (I264ca, b/173208140)
- Made PointerInputData's uptime and position fields non-nullable. (Id468a)
- offsetPx modifiers were renamed to offset. They are now taking lambda parameters instead of State. (Ic3021, b/173594846)
- New APIs for running animations in coroutines (Ied662)
- 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) - Time control in tests (TestAnimationClock and its usages) is now experimental (I6ef86, b/171378521)
- Remove old ui-test module and its stubs (I3a7cb)
RestorableStateHolder.withRestorableState
function was renamed toRestorableStateProvider
(I66640)- The Alignment interface was updated and made functional. (I46a07, b/172311734)
Version 1.0.0-alpha07
November 11, 2020

and androidx.compose.animation:animation-core:1.0.0-alpha07
are released. Version 1.0.0-alpha07 contains these commits.
Bug Fixes
- 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)
- MeasureResult was moved out of MeasureScope. (Ibf96d, b/171184002)
- Several layout related symbols were moved from androidx.compose.ui to androidx.compose.layout.ui. (I0fa98, b/170475424)
Version 1.0.0-alpha06
October 28, 2020
androidx.compose.animation:animation:1.0.0-alpha06
and androidx.compose.animation:animation-core:1.0.0-alpha06
are released. Version 1.0.0-alpha06 contains these commits.
API Changes
- Enable transitions in ComposeTestRule; remove option to enable the blinking cursor from ComposeTestRule. (If0de3)
Version 1.0.0-alpha05
October 14, 2020
androidx.compose.animation:animation:1.0.0-alpha05
and androidx.compose.animation:animation-core:1.0.0-alpha05
are released. Version 1.0.0-alpha05 contains these commits.
API Changes
- New Animation interface and subclasses: These classes store the start and end conditions for animations, and therefore allow value and velocity to be queried via only playtime (Ie95bd, b/163329867)
Bug Fixes
- OnPositionedModifier is renamed to OnGloballyPositionedModifier and onPositioned() is renamed to onGloballyPositioned(). (I587e8, b/169083903)
Deprecates contentColor() and currentTextStyle() APIs, and replaces them with AmbientContentColor and AmbientTextStyle ambients respectively. You can access the current value by using
.current
on the ambient property, as with any other ambient. This was change was made for consistency and to avoid having multiple ways to accomplish the same thing. Additionally renames some ambient properties to better describe their purpose as follows:- ContentColorAmbient -> AmbientContentColor
- TextStyleAmbient -> AmbientTextStyle
- IndicationAmbient -> AmbientIndication
- EmphasisAmbient -> AmbientEmphasisLevels
- RippleThemeAmbient -> AmbientRippleTheme (I37b6d)
Version 1.0.0-alpha04
October 1, 2020
androidx.compose.animation:animation:1.0.0-alpha04
and androidx.compose.animation:animation-core:1.0.0-alpha04
are released. Version 1.0.0-alpha04 contains these commits.
API Changes
- Annotated rootAnimationClockFactory, transitionsEnabled, blinkingCursorEnabled and textInputServiceFactory with @VisibleForTesting, make them internal API and hide their kdoc (I554eb, b/168308412)
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
- Removed RoundRect.middleRect/tallMiddleRect/wideMiddleRect and Rect.isStadium methods
- Renamed RoundRect.longestSide to RoundRect.maxDimension
- Renamed RoundRect.shortestSide to RoundRect.minDimension
- Changed RoundRect.center to be a property instead of a function
- 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)
- foundation.Box was deprecated. Please use foundation.layout.Box instead. (Ie5950, b/167680279)
- Stack was renamed to Box. The previously existing 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)
- 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)
Version 1.0.0-alpha03

September 2, 2020
androidx.compose.animation:animation:1.0.0-alpha02
and androidx.compose.animation:animation-core:1.0.0-alpha02
are released. Version 1.0.0-alpha02 contains these commits.
API Changes
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") } }
Bug Fixes
onPreCommit is deprecated; onCommit now has onPreCommit's behavior.
onCommit and onActive now run in the same choreographer frame that the composition changes committed in rather than at the beginning of the next choreographer frame. (I70403)
Version 1.0.0-alpha01
August 26, 2020
androidx.compose.animation:animation:1.0.0-alpha01

New Features
API Changes
- Offset has become an inline class (Iaec70)
- IntOffset is now an inline class (Iac0bf)
- IntSize is now an inline class (I2bf42)
AnimatedVisibilty composable animates the appearance and disappearance of the child content.
EnterTransition and ExitTransition are introduced to work with AnimatedVisibilty composable to provide 3 different typs of appearance and disappearance animation: fade, slide, and expand/shrink the content. The different types of animations can be combined to achieve more bespoke look and feel. (Idda11)
Deprecated PxBounds in favor of Rect. Updated all usages of PxBounds with rect and added proper deprecate/replace with annotations to assist with the migration. (I37038, b/162627058)
Bug Fixes
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)- 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)

, etc (I3e273) - Support end listener in
Modifier.animateContentSize()
such that when size change animation finishes, the listener will be notified, along with start/end size of the animation. (I277b2) - New animateContentSize modifier that animates the layout size change of its child modifier (Ieffdc)
Added
MonotonicFrameAnimationClock
that enables you to use a MonotonicFrameClock as anAnimationClockObservable
to bridge the gap between the new coroutines based clocks and APIs that still use the old callback based clocks.The
MonotonicFrameClock
equivalent ofManualAnimationClock
is nowManualFrameClock
. (I111c7, b/161247083)
Bug Fixes
- 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)
- Require type T to be explicitly specified for transitionDefinition. (I1aded)
- foundation.shape.corner package were flatten to foundation.share (I46491, b/161887429)
- 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) - Modifier.drawBackground has been renamed to Modifier.background (I13677)
Version 0.1.0-dev15
July 22, 2020
androidx.compose.animation:animation:0.1.0-dev15
and androidx.compose.animation:animation-core:0.1.0-dev15
are released. Version 0.1.0-dev15 contains these commits.
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
- Transition API has been changed to return a TransitionState instead of passing the TransitionState to children. This makes the API more consistent with animate() APIs. (I24e38)
- Modifier parameter added for Crossfade (I87cfe, b/159706180)
- 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)
- Replaced usage of IntPx with Int. Replaced IntPxPosition with IntOffset. Replaced IntPxSize with IntSize. (Ib7b44)
- 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)
- 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)
- Added animate() support for Dp, Px, Size, Position, Bounds, PxPosition, PxSize, PxBounds, IntPx, IntPxSize, IntPxPosition, IntPxBounds, and AnimationVector (Ib7518)
- Crossfade now accepts optional AnimationBuilder param to allow configuring the animation (I6d6e0)
- Replaced all nullable Color uses in API with non-nullable and use Color.Unset instead of null (Iabaa7)
- 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. (I79530)
- Breaking changes to the ambients API. See log and
Ambient<T>
documentation for details (I4c7ee, b/143769776) - New repeat mode: Reverse. This mode reverses the previous iteration as the animation repeats in RepeatableSpec or VectorizedRepeatableSpec. (Ibe0f5)
- API additions to ManualAnimationClock:
hasObservers: Boolean
and constructor parameterdispatchOnSubscribe: Boolean
(Iaa134) - Added APIs for getting min/max bounds in AnimatedFloat (Icd9cc)
Bug Fixes
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)
- Introduced low level stateless animation APIs. These APIs (I63bf7)
- The Recompose composable is no longer a useful abstraction. Most recomposition should happen as a result of MutableState assignments. For anything beyond that, it is recommended that you use the
invalidate
function to trigger a recomposition of the current scope. (Ifc992) - 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 (Id3434)
- Crossfade can now work with null as initial value (Iad6a4, b/155947711)
- 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)
- 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)
- 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)
- Added verticalGravity and horizontalGravity parameters to Row and Column, respectively. (I7dc5a)
- ui-text module is renamed as ui-text-core (I57dec)
- 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)
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) - ColoredRect has been deprecated. Use
Box(Modifier.preferredSize(width, height).drawBackground(color))
instead. (I499fa, b/152753731) - Replaced Modifier plus operator with factory extension functions (I225e4)
- 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)
- The Opacity composable function has been replaced with the drawOpacity modifier. (I5fb62)
- Tests using AndroidComposeTestRule now provide an animation clock at the root of the composition that allows it to be paused, resumed and advanced manually. (Id54c5)
- 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)
- Added copy methods to various
inline class types including:
- Offset
- Size
- Radius
- Motion
- TransformOrigin
- Deprecated Size.copy companion object method favor of instance copy method (Ife290, b/159905651)
- 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)
