How do I get ComponentActivity in a Composable?

rocketraman commented 1 year ago

It's not super-clear what to do here.

I've tried:

tailrec fun Context.getActivity(): AppCompatActivity? = when (this) {
  is AppCompatActivity -> this
  is Activity -> getActivity()
  is ContextWrapper -> baseContext.getActivity()
  else -> null
}

BLE(LocalContext.current.getActivity())

but that just results in:

E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.myapp, PID: 14836
    java.lang.IllegalStateException: LifecycleOwner com.myapp.MainActivity@183df6e is attempting to register while current state is RESUMED. LifecycleOwners must call register before they are STARTED.
