New Gradle property: android.native.buildOutput

To reduce clutter in build output, AGP 4.2 filters messages from native builds that use CMake and ndk-build, displaying only C/C++ compiler output by default. Previously, a line of output was generated for every file that was built, resulting in a large quantity of informational messages.

For usage information, see the release notes.

C++ editor: Set execution point in debugger

StateFlow support in data binding

For Kotlin apps that use coroutines, you can now use StateFlow objects as a data binding source to automatically notify the UI about changes in the data. Your data bindings will be lifecycle aware and will only be triggered when the UI is visible on the screen.

To use a StateFlow object with your binding class, you need to specify a lifecycle owner to define the scope of the StateFlow object, and in your layout, assign the properties and methods of your ViewModel component to the corresponding views using binding expressions, as shown in the following snippets: 


class ViewModel() {
   val username: StateFlow
}


<TextView
    android:id="@+id/name"
    android:text="@{viewmodel.username}" />


If you're in a Kotlin app that uses AndroidX, StateFlow support is automatically included in the functionality of data binding, including the coroutines dependencies.

To learn more, see the user guide.
