• It is now possible to constrain a baseline anchor to top/bottom anchors and vice versa. (I54628)
• Renamed MotionLayoutScope#motionProperties (including derivatives) to MotionLayoutScope#customProperties. This is to be consistent as when setting custom properties. (Ib34c9)
• It’s now possible to create multiple references in ConstraintSet and MotionScene: val (box, text, button) = createRefsFor("box", "text","button"). Apply constraints to multiple elements with constrain(box, button, text). Within a ConstrainScope, you may now intuitively set a fixed dimension with Dp.asDimension: width = 10.dp.asDimension. (I021ec, Ia0960)
• MotionScene() and Transition() methods are now non-Composable functions. The objects from these functions (including ConstraintSet) should now be properly comparable from each other. animateChanges = true in ConstraintLayout can now be used with only one ConstraintSet reference, as long as any of its properties changed on recomposition.

Lifecycle: v2.6.0-alpha05

January 25, 2023

androidx.lifecycle:lifecycle-*:2.6.0-alpha05 is released. Version 2.6.0-alpha05 contains these commits.

Kotlin Conversions

• Transformations is now written in Kotlin. This is a source incompatible change for those classes written in Kotlin that were directly using syntax such as Transformations.map - Kotlin code must now use the Kotlin extension method syntax that was previously only available when using lifecycle-livedata-ktx. When using the Java programming language, the versions of these methods that take an androidx.arch.core.util.Function method are deprecated and replaced with the versions that take a Kotlin Function1. This change maintains binary compatibility. (I8e14f)
• ViewTreeViewModelStoreOwner is now written in Kotlin. This is a source incompatible change for those classes written in Kotlin - you must now directly import and use the Kotlin extension methods on View of androidx.lifecycle.setViewTreeViewModelStoreOwner and androidx.lifecycle.findViewTreeViewModelStoreOwner to set and find a previously set owner. This is binary compatible and remains source compatible for implementations written in the Java programming language. (Ia06d8, Ib22d8, b/240298691)
• The HasDefaultViewModelProviderFactory interface is now written in Kotlin. This is a source incompatible change for classes written in Kotlin - they must now override the defaultViewModelProviderFactory and defaultViewModelCreationExtras properties rather than implementing the previous corresponding functions. (Iaed9c, b/240298691)
• Observer is now written in Kotlin. Its onChanged() method now uses the name value for its parameter. (Iffef2, I4995e, b/240298691)
• AndroidViewModel, AbstractSavedStateViewModelFactory, LifecycleService, ServiceLifecycleDispatcher, and ProcessLifecycleOwner are now written in Kotlin (I2e771, Ibae40, I160d7, I08884, I1cda7, b/240298691)

Mediarouter: v1.4.0-beta01

January 25, 2023

androidx.mediarouter:mediarouter:1.4.0-beta01 is released. Version 1.4.0-beta01 contains these commits.

API Changes

DynamicGroupRouteController.notifyDynamicRoutesChanged() now throws IllegalArgumentException when no route passed is SELECTED or SELECTING. (8f6b3e)

Bug Fixes

• Fix crash caused by an api-compliant provider service implementation returning a null route provider. (63f16d)
• Make protected broadcast receivers work on apps targeting API 33+ by marking them as non-exported. (784f8b)
• Fix some spurious nullability annotations in OverlayListView. (472e3f)
• Fix bug where EXTRA_CLOSE_ON_CONNECT in SystemOutputSwitcherDialogController.showDialog would cause the bluetooth settings fragment to close suddenly on wear devices. (28c9d8)
• Changed to Javadoc of Output Switcher’s public methods. (f0ae94, 44d2c9)

Wear: v1.3.0-alpha04

January 25, 2023

Wear Compose: v1.2.0-alpha03

January 25, 2023

androidx.wear.compose:compose-*:1.2.0-alpha03 is released. Version 1.2.0-alpha03 contains these commits.

API Changes

• We have migrated ScalingLazyColumn (and associated classes) from androidx.wear.compose.material.ScalingLazyColumn to andrdoidx.wear.compose.foundation.lazy.ScalingLazyColumn (see this example for migration). This new location more closely matches that of compose.foundation.lazy.LazyColumn and is more natural as it is not an opinionated Material component. The change is happening now in preparation for a new Material3 library, which we will be working on in parallel with the existing Material library. (I060e7)

The following changes are part of the ScalingLazyColumn migration from Material to Foundation.Lazy:

• PositionIndicator apis targeting Material ScalingLazyColumn have been deprecated - please update to Foundation.Lazy ScalingLazyColumn. Additionally anchorType field was added to ScalingLazyListLayoutInfo. (I29d95)
• ScalingLazyColumn has been marked as deprecated in the Wear Compose Material package (I16d34)
• We have updated the ScrollAway modifier to use ScalingLazyListState from Wear Compose Foundation.Lazy and deprecated the overload that took ScalingLazyListState from Wear Compose Material. (Ifc42c)
• We have updated the Dialog APIs to use ScalingLazyListState from Foundation.Lazy and deprecated the overloads that used Material ScalingLazyListState (Ic8960)
• We have updated the Picker APIs to use ScalingParams from Foundation.Lazy and deprecated the overloads that used Material ScalingParams. (Idc3d8)

Bug Fixes

• We have fixed a bug that caused unnecessary recompositions in ScalingLazyListState.centerItemIndex by ensuring that it only pushes updates when the value actually changes (Ia9f38)
• We have improved the performance of SwipeToDismissBox (I3933b)
• Added benchmark tests for ScalingLazyColumn in Wear Compose Foundation (Ie00f9)
• We have updated some internal ScalingLazyColumn classes methods in Material to use their equivalents from Foundation.Lazy (I38aab)
• We have fixed some issues in Picker tests and add more tests for checking scroll with offset (I6ac34)
• We migrated the ScalingLazyColumn Integration Demos to depend on Foundation.Lazy instead of Material ScalingLazyColumn (Ic6caa)
• We have added optional fromDate/toDate parameters to our DatePicker demo (I961cd)

wear protolayout: v1.0.0-alpha02

January 25, 2023

androidx.wear.protolayout:protolayout:1.0.0-alpha02, androidx.wear.protolayout:protolayout-expression:1.0.0-alpha02, and androidx.wear.protolayout:protolayout-proto:1.0.0-alpha02 are released. Version 1.0.0-alpha02 contains these commits.

New Features

• Layout builders from androidx.wear.tiles:tiles are moving to androidx.wear.protolayout:protolayout. The ones in androidx.wear.tiles:tiles will be deprecated in one of the next alpha releases.

Wear Watchface: v1.2.0-alpha06

January 25, 2023

androidx.wear.watchface:watchface-*:1.2.0-alpha06 is released. Version 1.2.0-alpha06 contains these commits.

New Features

Webkit: v1.7.0-alpha01

January 25, 2023

androidx.webkit:webkit:1.7.0-alpha01 is released. Version 1.7.0-alpha01 contains these commits.

New Features

• We are adding support for Image drag in WebView. You can enable your users to drag images out of the WebView by adding the new DropDataContentProvider to your app's manifest. (05a1a6)

Webkit: v1.6.0

January 25, 2023

androidx.webkit:webkit:1.6.0 is released. Version 1.6.0 contains these commits.

Important changes since 1.5.0

• A new ProcessGlobalConfig API has been added to allow apps to provide configuration settings that need to be set before loading WebView, such as the WebView data directory suffix. The configuration should be set up and applied as early as possible during application startup, to ensure that it happens before any other thread can call a method that loads WebView into the process.
• A new CookieManagerCompat API has been added to expand android.webkit.CookieManager with a new getCookieInfo method, which retrieves all attributes for all cookies set on a specific URL. This differs from the existing getCookie API in CookieManager which returns only the name and value attributes of the cookies.
• WebSettingsCompat has new methods to enable/disable the effect of EnterpriseAuthenticationAppLinkPolicy if set by admin in WebView, and to get the current setting. This feature lets WebView open an Authentication app instead of opening the authentication URL. This feature has no effect on devices that are not managed by an enterprise policy.
• Adding a new API to WebSettingsCompat to let applications explicitly send the app package name in the X-Requested-With header to allowlisted origins. The header has traditionally been sent on every request from WebView.
