New Features
BasicTextField and SelectionContainer 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)isPositionedByParentWithDirectManipulation to introducesFrameOfReference. Note that it now has the reverse effect, meaning that by default, most LayoutCoordinates 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, use positionInLocalFrameOfReference(...). Or positionInLocalLookaheadFrameOfReference from a LookaheadScope.

To disable a ripple, instead of providing a RippleConfiguration with isEnabled = false, provide null to LocalRippleConfiguration. (I22725)ModalBottomSheet more accurately draws scrim over status bar when edge to edge is enabled. Modal bottom sheet content can now consume window insets, allowing for visible content above the navigation bar. ModalBottomSheet parameter windowInsets renamed to contentWindowInsets to specify where the insets will be applied, these are no longer tied to window logic. contentWindowInsets type has been changed to a function which returns WindowInsets, to allow it to be resolved within its new window. (I39630, b/274872542, b/300280229, b/290893168)PrimaryScrollableTabRow and SecondaryScrollableTabRow now use custom layout instead of subcomposition, which should improve performance.

Predictive Back Gesture Support
Animator or when using AndroidX Transition 1.5.0. This allows users to use the back gesture to see the previous fragment by seeking your Animator/Transition before deciding to either commit the transaction via completing the gesture or canceling.| Transition System | XML Resource | Supports Predictive Back |

If you see any issues with Predictive Back support in Fragments after you’ve opted into the predictive back gesture, please file an issue against Fragment with a sample project that reproduces your issue. You can disable predictive back by using FragmentManager.enabledPredictiveBack(false) in the onCreate() of your Activity.
FragmentManager.OnBackStackChangedListener() now provides the onBackStackChangeProgressed() and onBackStackChangeCancelled() for receiving predictive back progress and canceled events respectively.
Fragment Compose Artifact
A new fragment-compose artifact has been created that focuses on supporting apps that are in the process of moving from a Fragment based architecture to a fully Compose based architecture.
The first feature available in this new artifact is a content extension method on Fragment that seeks to make it easier to use Compose for the UI of an individual Fragment by creating a ComposeView for you and setting the correct ViewCompositionStrategy.
class ExampleFragment : Fragment() {
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
) = content {
// Write your @Composable content here
val viewModel: ExampleViewModel = viewModel()
// or extract it into a separate, testable method
ExampleComposable(viewModel)
}

Safe Args in Navigation Compose
This functionality uses Kotlin Serialization to allow you to define destinations in your navigation graph via type safe objects and data classes:
// Define a home destination that doesn't take any arguments
@Serializable
object Home
// Define a profile destination that takes an ID
@Serializable
data class Profile(val id: String)
// Now define your NavHost using type safe objects
NavHost(navController, startDestination = Home) {
composable<Home> {
HomeScreen(onNavigateToProfile = { id ->
navController.navigate(Profile(id))
})
}
composable<Profile> { backStackEntry ->
val profile: Profile = backStackEntry.toRoute()
ProfileScreen(profile)
}
}
See the Navigation Compose meet Type Safety blog post for more information.

androidx.room:room-*:2.7.0-alpha01 is released. Version 2.7.0-alpha01 contains these commits.
New Features
For more information on how to get started using Room KMP, please refer to the official Room KMP documentation.
API Changes
Room.databaseBuilder() has been added that takes a lambda parameter that is meant to be used with a Room generated function to avoid using reflection when instantiating the generated RoomDatabase implementation. Example usage is: kotlin Room.databaseBuilder<MyDatabase>( context = appContext name = dbFilePath, factory = { MyDatabase::class.instantiateImpl() } )CoroutineContext has been added to the builder: RoomDatabase.Builder.setQueryCoroutineContext. Note that a RoomDatabase can only be configured with either executors using setQueryExecutor or with a Coroutine context but not both.SQLite Driver has been added: RoomDatabase.Builder.setDriver(). For more information about the SQLite Driver API refer to the SQLite KMP documentationSQLiteConnection from driver APIs have been added: RoomDatabase.useReaderConnection and RoomDatabase.useWriterConnection.SQLiteConnection instead of SupportSQLiteDatabase. These are intended to be overridden when migrating to a KMP project. For more information about migrating Room usages in an Android app to a common KMP module refer to the migration guide. The callbacks are:
Migration.migrate(SQLiteConnection)AutoMigrationSpec.onPostMigrate(SQLiteConnection)RoomDatabase.Callback.onCreate(SQLiteConnection)RoomDatabase.Callback.onDestructiveMigration(SQLiteConnection)RoomDatabase.Callback.onOpen(SQLiteConnection)androidx.room:room-ktx has been merged to androidx.room:room-runtime along with all its APIs, the artifact is now blank. Please remove it from your dependency list.May 1, 2024
androidx.sqlite:sqlite-*:2.5.0-alpha01 is released. Version 2.5.0-alpha01 contains these commits.
New Features
SQLite APIs that enable Room to be KMP have also been updated. The package andriodx.sqlite contains three interfaces that define low-level SQLite APIs: SQLiteDriver, SQLiteConnection and SQLiteStatement. The artifact androidx.sqlite:sqlite-framework offers implementation of the interfaces for Android and iOS Natively, while androidx.sqlite:sqlite-bundled offers an implementation that uses SQLite compiled from source (also known as “bundled SQLite”). For more information about the SQLite Driver API refer to the official SQLite KMP documentation.May 1, 2024

Important changes since 1.4.0
TransitionManager, controlDelayedTransition(), which returns a TransitionSeekController that allows seeking the Transition. This functionality is used by Fragment 1.7.0 to automatically seek transitions when using the Predictive Back Gesture.getRootTransition(), that returns the Transition containing the current Transition or the current Transition if it isn't contained by any other Transition. This can be useful if the developer needs to have listeners for when the entire Transition starts or ends.TransitionListeners now have new onTransitionStart() and onTransitionEnd() listeners that allow the developer to know whether the transition is starting or ending going in reverse or not. This can be important for developing seekable transitions that have TransitionListeners.May 1, 2024

Check out this sample to learn how to build it yourself. (Id48da)MutableInteractionSource in their API have been updated to now expose a nullable MutableInteractionSource that defaults to null. There are no semantic changes here: passing null means that you do not wish to hoist the MutableInteractionSource, and it will be created inside the component if needed. Changing to null allows for some components to never allocate a MutableInteractionSource, and allows for other components to only lazily create an instance when they need to, which improves performance across these components. If you are not using the MutableInteractionSource you pass to these components, it is recommended that you pass null instead. It is also recommended that you make similar changes in your own components. (I309b4, b/298048146)TextAlign parameter is now non-null (Ib73b1, b/299490814)TextAlign, TextDirection, Hyphens and LineBreak fields of the ParagraphTextStyle to replace (I4197e, b/299490814)May 1, 2024
