Android Studio – My android app keeps crashing from which seems to be a permission problem despite granting the relevant permission in the Manifest

Below is the MainActivity code from which the problem is arising from.


class MainActivity : AppCompatActivity(), NavigationView.OnNavigationItemSelectedListener,
    AdapterView.OnItemSelectedListener {

    private var user: FirebaseUser? = null
    var activity: MainActivity? = null
    private var mUserRef: DatabaseReference? = null
    private lateinit var dialog: AlertDialog
    lateinit var bottomSheet: BottomSheetLayout
    lateinit var cView: View
    lateinit var tView: View


    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val toolbar: Toolbar = findViewById(R. id.toolbar)
        setSupportActionBar(toolbar)

        
        activity = this@MainActivity
        user = Firebase.auth.currentUser
        dialog = SpotsDialog.Builder().setContext(this).build()
        dialog.show()

        val network = Network(this)
        val imei = network.imei
        val imsi = network.imsi
        Log.e("deviceInfo", "$imei $imsi")

        if (user != null) {
            Log.d("UserData", user!!.metadata!!.lastSignInTimestamp.toString())
            // User is signed in
            user.let {


                val db = Firebase.firestore
                mUserRef = FirebaseDatabase.getInstance().reference.child("users")
                    .child(user!!.uid)

                val docRef = db.collection("users").document(user!!.uid)
                docRef.get()
                    .addOnSuccessListener { document ->
                        if (document != null) {

I’m getting a FATAL EXCEPTION due to Read Phone State permission not being granted at

val network = Network(this)

even after listing the necessary permissions in the manifest. Kindly let me know how I can fix that.

    This works too.

    private val requestPermission =

    registerForActivityResult(ActivityResultContracts.RequestPermission()) { isGranted ->
        // Do something if permission granted
        if (isGranted) {
            Log.i("DEBUG", "permission granted")
        } else {
            Log.i("DEBUG", "permission denied")
        }
    }

override fun onCreate(savedInstanceState: Bundle?) {
                super.onCreate(savedInstanceState)
                setContentView(R.layout.activity_main)
         

                requestPermission.launch(Manifest.permission.READ_PHONE_STATE)

    }

    Something like this should work:

    val requestPermissionLauncher = registerForActivityResult(RequestPermission()) { isGranted: Boolean ->
    if (isGranted) {
        // Permission granted. App continues with permission
    } else {
        // Explain why the permission is needed to the user
    }
}

when {
  ContextCompat.checkSelfPermission(CONTEXT, Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED -> {
    // Use the permission!
  }
  shouldShowRequestPermissionRationale(...) -> {
      showInContextUI(...)
  }
  else -> {
      requestPermissionLauncher.launch(Manifest.permission.READ_PHONE_STATE)
  }
}
