How to Handle Dynamic Permissions for Bluetooth in Android 14 with Jetpack Compose?

android jetpack-compose permissions bluetooth kotlin

I'm relatively new to this, so bear with me. I'm working with an scenario with handling dynamic permissions for Bluetooth in my Android 14 app that uses Jetpack Compose. I've implemented the necessary permission checks using `ActivityCompat.requestPermissions`, but I'm confused about the right lifecycle management when switching between Composables. My app crashes with `java.lang.SecurityException: Need BLUETOOTH permission`. I've tried checking for permissions using `ContextCompat.checkSelfPermission` before attempting to enable Bluetooth, but the permission request doesn't seem to trigger properly when navigating between screens. Here's a simplified version of my code: ```kotlin @Composable fun BluetoothScreen() { val context = LocalContext.current val permissionState = rememberPermissionState(permission = Manifest.permission.BLUETOOTH) LaunchedEffect(Unit) { if (permissionState.status != PermissionStatus.Granted) { permissionState.launchPermissionRequest() } } if (permissionState.status.isGranted) { // Code to enable Bluetooth } else { Text(text = "Bluetooth permission required") } } ``` I've also tried managing the permission state using ViewModel, but it doesn't seem to reflect changes after navigating back to the Bluetooth screen. Any suggestions on how to properly manage Bluetooth dynamic permissions in a Jetpack Compose setup? Is there a recommended way to ensure that the permission request is consistently handled, especially when transitioning between different screens? I want to avoid the app crashing or the permission request being skipped altogether. This is part of a larger application I'm building. Any ideas what could be causing this?
