Android 12 Pending Intent

Issue

Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent. Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable

I can't update the pending intent flag in android studio project coding

This is a place in AlarmPingSender.java where the error occurred

  public void start()        
   {       
   String action = MqttServiceConstants.PING_SENDER
            + comms.getClient().getClientId();
    Log.d(TAG, "Register alarmreceiver to MqttService"+ action);
    service.registerReceiver(alarmReceiver, new IntentFilter(action));

    pendingIntent = PendingIntent.getBroadcast(service, 0, new Intent(
            action), PendingIntent.FLAG_UPDATE_CURRENT);

    schedule(comms.getKeepAlive());
    hasStarted = true;
}

Help me to fix the issue ERROR IN ANDROID STUDIO IMAGE

Solution

You need to do this:

pendingIntent = PendingIntent.getBroadcast(service, 0, new Intent(
        action), PendingIntent.FLAG_UPDATE_CURRENT |
                 PendingIntent.FLAG_IMMUTABLE);

Since you are using AlarmManager you should be able to use the IMMUTABLE flag.
