Composable Function
rememberAmbientModeManager
Android
```kotlin
@Composable
public fun rememberAmbientModeManager(): AmbientModeManager
```
Creates, remembers, and manages the lifecycle of the default `AmbientModeManager` implementation.
**This function requires a `LocalActivity` be present and automatically enables Always-On mode
for that activity, ensuring it remains visible in the low-power ambient state.**
The resulting `AmbientModeManager` is retained across recompositions via `remember` and its
system listeners are automatically registered and unregistered using `DisposableEffect`, tying
the ambient tracking to the composition lifecycle.
See the Android documentation for more details on enabling Always-On mode:
