  ComposeView(this).apply {
    setContent {
      MyComposableContent()
    }
  }
)

LocalActivity

View Source

Added in 1.10.0

val LocalActivity: ProvidableCompositionLocal<Activity?>

Provides the Activity belonging to the current LocalContext.

Note, when possible you should always prefer using the finer grained composition locals where available. This API should be used as a fallback when the required API is only available via Activity.
