([I2a035](https://android-review.googlesource.com/#/q/I2a035)) - **Interruption Handling:** Fixed the corner case interruption handling when a child exit animation finishes while the parent transition is still running in `AnimatedContent`. ([ad9b4f](https://android-review.googlesource.com/#/q/ad9b4f)) - **Validation:** Validated duration in `InfiniteRepeatableSpec` to prevent 0-duration cycles. ([151b6d](https://android-review.googlesource.com/#/q/151b6d)) - **Customization:** Respect `visibilityThreshold` in custom `AnimationSpec` for `animateFloatAsState`.

More specifically, when a transitioning shared element is being scrolled, the scroll delta will be directly applied to the shared element rather than causing the shared elements to chase the new target. ([cacf7b](https://android-review.googlesource.com/#/q/cacf7b9)) ### Version 1.9.0-alpha01 April 23, 2025 `androidx.compose.animation:animation-*:1.9.0-alpha01` is released. Version 1.9.0-alpha01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/d6d9afca3dfa73c1b9ea74daf9d6ad49c56fe0e9..008cbd021e3a2b4d1f36ea7f48200c4692bfc169/compose/animation). **Behavior Changes** - Lint checks shipped with Compose now require a minimum AGP version of 8.8.2. If you are unable to upgrade AGP, you can instead upgrade Lint on its own by using `android.experimental.lint.version=8.8.2` (or a newer version) in your `gradle.properties`. To run Compose lint checks inside the IDE, Android Studio Ladybug or newer is required. **New Features** - Improved scrolling performance for shared elements ([ea4f1f](https://android-review.googlesource.com/#/q/ea4f1f2)) **API Changes** - Projects released with Kotlin 2.0 require KGP 2.0.0 or newer to be consumed. ([Idb6b5](https://android-review.googlesource.com/#/q/Idb6b5d6ae1625ab870ffe74f9790ffabc82a63b4)) - `TabRow` and `ScrollableTabRow` are deprecated in favor of Primary and Secondary variants of each.

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](https://android-review.googlesource.com/#/q/Icb0b953f1eaff80a582b1edd3f21f9f8031cf8b0)) - New `scaleInSharedContentToBounds` and `scaleOutSharedContentToBounds` to scale content in `sharedBounds` ([I731c1](https://android-review.googlesource.com/#/q/I731c18d0bd9a533bbf53ebba62f4638bdc758cbe)) - Experimental `SharedTransitionScope` is now an interface rather than a class. ([Iaf856](https://android-review.googlesource.com/#/q/Iaf856b84ad2d91f94f8e294f015b6341808fcc74)) - New `resizeModes` (`ScaleToBounds` and `RemeasureToBounds`) for `sharedBounds` to choose between scaling and remeasure. The previous `scaleIn/OutSharedContentToBounds` APIs are now deprecated. ([I0d41a](https://android-review.googlesource.com/#/q/I0d41aa7395b84f0232c1c64281e95f693526faa9)) Improvements to existing APIs: - New `Modifier.animateContentSize` that takes an additional parameter for custom content alignment.

This matches the behavior of compose when running normally. However, tests that rely on the old behavior may fail.

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](https://developer.android.com/reference/kotlin/androidx/compose/material3/package-summary#navigationrail) - Graduates a number of previously experimental APIs to stable - [Support](https://developer.android.com/jetpack/androidx/releases/compose-kotlin) for newer versions of Kotlin ### Version 1.1.0-rc03 January 26, 2022 `androidx.compose.animation:animation:1.1.0-rc03`, `androidx.compose.animation:animation-core:1.1.0-rc03`, and `androidx.compose.animation:animation-graphics:1.1.0-rc03` are released.

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 using `adb 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: -> - And a class rule will have the following pattern: - Here `` is one or more of the characters `H`, `S`, and `P` to indicate whether or not this method should be flagged as "Hot", "Startup", or "Post Startup". - The `` is the descriptor for the class that the targeted method belongs to. For example, the class `androidx.compose.runtime.SlotTable` would have a descriptor of `Landroidx/compose/runtime/SlotTable;`. - The `` is the signature of the method, and includes the name, parameter types, and return types of the method. For example, the method `fun isPlaced(): Boolean` on `LayoutNode` has the signature `isPlaced()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 June 2, 2021 `androidx.compose.animation:animation:1.0.0-beta08` and `androidx.compose.animation:animation-core:1.0.0-beta08` are released.

You should use `rememberSaveable { 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 `stateSaver` parameter.

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.

([I080b3](https://android-review.googlesource.com/#/q/I080b3cb674dc32af5fbe7e696228ac21f0720d72)) - Require type T to be explicitly specified for transitionDefinition. ([I1aded](https://android-review.googlesource.com/#/q/I1adedb34525ebb8c079a77a9af2636f1cb8339f7)) - foundation.shape.corner package were flatten to foundation.share ([I46491](https://android-review.googlesource.com/#/q/I464919cb74f8941c2a02f14dea0aa417febf3691), [b/161887429](https://issuetracker.google.com/issues/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](https://android-review.googlesource.com/#/q/Iedd587edbed0ba964ef203a66b98be7297147bd7), [b/161529964](https://issuetracker.google.com/issues/161529964)) - Modifier.drawBackground has been renamed to Modifier.background ([I13677](https://android-review.googlesource.com/#/q/I1367723fce0e07418ed4ab391fe20c69aa092f53)) ### 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.](https://android.googlesource.com/platform/frameworks/support/+log/9f60cc700129e30cee9df020005c317fb39d32ec/ui) #### 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](https://developer.android.com/jetpack/androidx/releases/compose-animation#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](https://android-review.googlesource.com/#/q/I24e38fea3bf299e47d87dc5d2b42991e03d6786c)) - Modifier parameter added for Crossfade ([I87cfe](https://android-review.googlesource.com/#/q/I87cfe587dd58ee662d8e589274978aef44bbdf99), [b/159706180](https://issuetracker.google.com/issues/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](https://android-review.googlesource.com/#/q/Ica0b4cb42996d3d30f9b6dacdbe149c75af77341)) - Replaced usage of IntPx with Int. Replaced IntPxPosition with IntOffset. Replaced IntPxSize with IntSize. ([Ib7b44](https://android-review.googlesource.com/#/q/Ib7b44d92ce3aff86c606753f0ac5c3122b71041d)) - 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](https://android-review.googlesource.com/#/q/Ic019171b52d2f24d262d9c47ac964728cdc1ee8b)) - 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](https://android-review.googlesource.com/#/q/I3ad983207bc37af20afac03e2cd09b4240777687)) - 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](https://android-review.googlesource.com/#/q/I086f4744d1eb51f0f31356e36991c2a8d4433059)) - Added animate() support for Dp, Px, Size, Position, Bounds, PxPosition, PxSize, PxBounds, IntPx, IntPxSize, IntPxPosition, IntPxBounds, and AnimationVector ([Ib7518](https://android-review.googlesource.com/#/q/Ib75184a2dc31986f8eb3698a428cbd8483104f61)) - Crossfade now accepts optional AnimationBuilder param to allow configuring the animation ([I6d6e0](https://android-review.googlesource.com/#/q/I6d6e03ec54221b740d7c88bdb8a8c93a662280a4)) - Replaced all nullable Color uses in API with non-nullable and use Color.Unset instead of null ([Iabaa7](https://android-review.googlesource.com/#/q/Iabaa7c6334857833cdb0d5958f062e2e576bd240)) - 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](https://android-review.googlesource.com/#/q/I79530e117cfa893a52542f85a55528eaa0f11b93)) - Breaking changes to the ambients API. See log and `Ambient` documentation for details ([I4c7ee](https://android-review.googlesource.com/#/q/I4c7eea45f2b7bf41f8a8ba75fd667c06010469a9), [b/143769776](https://issuetracker.google.com/issues/143769776)) - New repeat mode: Reverse. This mode reverses the previous iteration as the animation repeats in RepeatableSpec or VectorizedRepeatableSpec. ([Ibe0f5](https://android-review.googlesource.com/#/q/Ibe0f50b12223911f87f4541c683f55bc25ad0a3f)) - API additions to ManualAnimationClock: `hasObservers: Boolean` and constructor parameter `dispatchOnSubscribe: Boolean` ([Iaa134](https://android-review.googlesource.com/#/q/Iaa1346a80d6c0ff3b3a4a1ff01cccadbca3407bc)) - Added APIs for getting min/max bounds in AnimatedFloat ([Icd9cc](https://android-review.googlesource.com/#/q/Icd9ccde2e7d163b28d3a7a7d9193bcb4a0c05f9e)) **Bug Fixes** - `runOnIdleCompose` renamed to `runOnIdle` ([I83607](https://android-review.googlesource.com/#/q/I836071f1c3c63d21417a531f336f8a93ca13f9ed)) - Several testing APIs were renamed to be more intuitive. All findXYZ APIs were renamed to onNodeXYZ. All doXYZ APIs were renamed to performXYZ. ([I7f164](https://android-review.googlesource.com/#/q/I7f164b42b04196f023c4a2153d66825487998de4)) - Introduced low level stateless animation APIs. These APIs ([I63bf7](https://android-review.googlesource.com/#/q/I63bf7d28d5ac5e5ca2caaa427ee7643828c848a5)) - 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](https://android-review.googlesource.com/#/q/Ifc9926013c51c1db1e27e702a707bc1050f82fa6)) - 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.

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](https://android-review.googlesource.com/#/q/I1798e4b2b325297c3b5394aa99be3db935e369b7)) - 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](https://android-review.googlesource.com/#/q/I80afdf4c0a648962aa6ef1efc05b1d3b65757094)) - Added verticalGravity and horizontalGravity parameters to Row and Column, respectively. ([I7dc5a](https://android-review.googlesource.com/#/q/I7dc5a4e757370075657be68e6eda68e7498228fa)) - ui-text module is renamed as ui-text-core ([I57dec](https://android-review.googlesource.com/#/q/I57dec72ca50e7288e37c9272ef6ce8bcc485a83e)) - 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](https://android-review.googlesource.com/#/q/Ibaced5feb8778510b8fe78e96f4fd3da1a6fda50), [b/152919067](https://issuetracker.google.com/issues/152919067)) - `runOnIdleCompose` and `runOnUiThread` are now global functions instead of methods on ComposeTestRule. ([Icbe8f](https://android-review.googlesource.com/#/q/Icbe8fd71d52144e855ccb4ce06a4677337be731a)) - \[Mutable\]State property delegate operators moved to extensions to support Kotlin 1.4 property delegate optimizations. Callers must add imports to continue using `by state { ... }` or `by mutableStateOf(...)`.

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](https://android-review.googlesource.com/#/q/Idf5e0d25a2a8764489d738f6fcf242eeb667e124)) - Renamed LayoutFlexible to LayoutWeight. Renamed tight parameter to fill. ([If4738](https://android-review.googlesource.com/#/q/If4738c70c381e149ded400d657b5efd888ae5891)) - The Opacity composable function has been replaced with the drawOpacity modifier. ([I5fb62](https://android-review.googlesource.com/#/q/I5fb62404e20e3f2a0fa94ad0fb121f35d05bbb1c)) - 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](https://android-review.googlesource.com/#/q/Id54c51482f554cdb512e4eb53c78930408778f94)) - Support right-to-left direction in LayoutPadding modifier ([I9e8da](https://android-review.googlesource.com/#/q/I9e8da0bfbb135ff7f34b0dc49b905f634ad7d18c)) - Density and DensityScope were merged into one interface.
