New Features

• Support lookahead in LazyList. This allows LazyList in the lookahead pass to bypass any animation (e.g. item placement animation, AnimatedVisibility, etc) and to calculate the lookahead size and position for all children. After the lookahead pass, children of LazyList could animate independently to the reality as seen in the lookahead pass.

Behavior Change: includeFontPadding is now false by default in Compose

includeFontPadding is now false by default (21d806) in Compose.

includeFontPadding is a legacy attribute that controls whether or not to include extra padding on top of the first line and last line of the text to accommodate any characters that may extend above or below the text baselines.

Updating this Compose version will modify how all texts render in your UI by removing the extra padding on top of the first line and last line of every text you display.

Depending on your UI requirements and the font metrics you’re using, the changes should be minimal. However you might encounter blockers such as: - Broken screenshot tests. Fix the UI if required, and regenerate the golden images. - Text is slightly misaligned. Remove any custom negative paddings or add padding if required.

You can opt-in to includeFontPadding by using PlatformTextStyle for each text:

Text(
 text = myText,
 style = TextStyle(
   lineHeight = 2.5.em,
   platformStyle = PlatformTextStyle(
     includeFontPadding = true/false
   )
   /* … */
  )
)

You can opt-in to includeFontPadding for all your texts by configuring your Material styles. Note that parameter names will vary between M2 and M3.

val Typography = Typography(
   body1 = TextStyle(
       fontFamily =    /* … */,
       fontSize =    /* … */,
       platformStyle = PlatformTextStyle(
           includeFontPadding = false
       )
   /* … */
   )
)
MaterialTheme(

typography = Typography,

/* … */

)

You can find more about Compose includeFontPadding in developer documentation and this blog post.

Room: v2.6.0-alpha02

June 21, 2023

androidx.room:room-*:2.6.0-alpha02 is released. Version 2.6.0-alpha02 contains these commits.

Room Gradle Plugin

This new release contains a new artifact for the Room Gradle Plugin with id androidx.room, which solves various existing issues in Room regarding having inputs and outputs of schemas via Gradle annotation processor options. The Room Gradle Plugin configures the project such that generated schemas that are consumed for auto-migrations and are output of the compile tasks are correctly configured to have reproducible and cacheable builds. The plugin offers a DSL to configure the base schema location:

room {
    schemaDirectory("$projectDir/schemas/")
}

The plugin will then configure the Room compiler and the various compile tasks and its backends (javac, KAPT, KSP) to output schema files into flavored folders, i.e. schemas/flavorOneDebug/com.package.MyDatabase/1.json. As usual these files are checks-in into the repository to be used for validation and auto-migrations. Upon migrating to using the plugin instead of the annotation processor options the existing schema files must be copied to the generated flavor directories created by the plugin, this is a one-time migration operation that must be done manually. The schema documentation in developers.android.com will be updated in the future once feedback is addressed and the plugin reaches stable, so please give it a try.

API Changes

• RoomDatabase.QueryCallback has been defined as a functional interface to allow SAM conversion usages. (Iab8ea, b/281008549)

Wear Compose: v1.3.0-alpha01

June 21, 2023

androidx.wear.compose:compose-*:1.3.0-alpha01 is released. Version 1.3.0-alpha01 contains these commits.

Bug Fixes

• As announced in 1.2.0-alpha07 and 1.2.0-alpha10, we are now changing the DefaultTextStyle to turn off font padding to be consistent across the Android Platform. This will address some cases of text clipping with large font sizes and may also impact screen layouts, so that screenshot tests need to be updated. For example, we see text clipping here (Ic6a86)

Figure 1: Text clipped.

• It is no longer present when font padding is turned off:

Figure 2: Text not clipped.

• We have updated wear.compose.foundation to be an API dependency of wear.compose.material (I72004, b/285404743)
• We have fixed a bug in SwipeToDismissBox. Background and content keys are now passed to the remember block so that new modifiers are created when the content or background changes. (Ib876c, b/280392104)
• We have updated TimeText to use the locale when choosing the format for 12 or 24 hour time. (If4a3d)
• We have fixed an inconsistency in SwipeToDismissBox contentScrimColor default parameters. (I2d70f)
• We have improved the motion handling in SwipeToReveal. (I28fb7)

Known Issues

• Supporting user-configured font sizes is an accessibility requirement. We know that multiline Chips can lead to text-clipping when displayed with large font sizes, so we will be updating Chip in an early 1.3 alpha version to make height adjustments in those cases.

HEART_RATE_ACCURACY_X int constants are now used directly in DynamicHeartRateAccuracy.constant() and DynamicHeartRateAccuracy.dynamicDataValueOf() instead of value constant. (I82ff5)
• The PlatformHealthSources.Constants class was instantiable by mistake. This has been fixed now. (Icb849)
• PlatformTimeUpdateNotifier#setReceiver now receives Runnable instead of Supplier function and Executor to notify on. (I9d938)
