Я хочу написать всегда на приложении для ОС. Мои часы Samsung используют Android 14.0. < /P>
Минимальный SDK установлен на 29, Target и Compillise SDK до 35. < /P>
Добавлен разрешение Wake_lock в Manifest. Методы AmbientLifeCycleCallback не вызываются. < /P>
Что я делаю неправильно?class MainViewModel : ViewModel() {
private val modeMutableStateFlow = MutableStateFlow("Interactive")
private val counterMutableStateFlow = MutableStateFlow(0)
val modeStateFlow = modeMutableStateFlow.asStateFlow()
val counterStateFlow = counterMutableStateFlow.asStateFlow()
fun updateMode(ambient: Boolean) {
modeMutableStateFlow.update { if(ambient) "Ambient" else "Interactive" }
}
fun updateCounter() {
counterMutableStateFlow.update { counterMutableStateFlow.value + 1 }
}
}
< /code>
mainactivity.kt
class MainActivity : ComponentActivity() {
private val vm: MainViewModel by viewModels()
private val callbacks = object : AmbientLifecycleObserver.AmbientLifecycleCallback {
override fun onEnterAmbient(ambientDetails: AmbientLifecycleObserver.AmbientDetails) {
// ... Called when moving from interactive mode into ambient mode.
Log.i(this.javaClass.simpleName, "enter ambient")
vm.updateMode(ambient = true)
