android.net.ConnectivityManager$TooManyRequestsException

Question

Note: Don't mark this as duplicate as this existing answer does not solved my query android.net.ConnectivityManager$TooManyRequestsException in android while network call

Update Wed 28 Jun : Found this is happening only on Android 11 devices.

I have added a callback to notify device is connected to internet or not code is giving me following exception in firebase I have never observed this issue on the app following is the exception log

I made sure to add and remove callback as mentioned in few solutions as below

connectivityManager = requireContext().getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
connectivityManager?.registerDefaultNetworkCallback(connectionCallback)

Unregister:

connectivityManager?.unregisterNetworkCallback(connectionCallback)

I am still able to see this crash any reason how to fix this?

Condition under which I add network callback when api call fails due to network not available and unregister call either when user comes back online or activity is destroyed.

 public Object notifyIfAppIsOnline(Runnable onAppIsOnline) {
    NetworkStateMonitor.Callback connectionStateListener = new NetworkStateMonitor.Callback() {
        @Override
        public void onNetworkStateChanged(boolean isOnline) {
            if (isOnline) {
                networkStateMonitor.removeCallback(this);
                onAppIsOnline.run();
            }
        }
    };

    networkStateMonitor.addCallback(connectionStateListener);

    return connectionStateListener;
}

public void onDestroy() {
    if (appIsOnlineNotification != null) {
        myRepository.cancelAppOnlineNotification(appIsOnlineNotification);
    }
 }
