Android 12 Pending Intent

Question

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

Use this two public methods when you want to create any PendingIntent in your project

Create activity pendingIntent

   public static PendingIntent createPendingIntentGetActivity(Context context, int id, Intent intent, int flag) {
         if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
             return PendingIntent.getActivity(context, id, intent, PendingIntent.FLAG_IMMUTABLE | flag);
         } else {
             return PendingIntent.getActivity(context, id, intent, flag);
         }
     }

Create broadcast pendingIntent

 public static PendingIntent createPendingIntentGetBroadCast(Context context, int id, Intent intent, int flag) {
     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
         return PendingIntent.getBroadcast(context, id, intent, PendingIntent.FLAG_IMMUTABLE | flag);
     } else {
         return PendingIntent.getBroadcast(context, id, intent, flag);
     }
 }

Kotlin answer:

fun getActivity(context: Context?, id: Int, intent: Intent?, flag: Int): PendingIntent {
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
        PendingIntent.getActivity(context, id, intent, PendingIntent.FLAG_MUTABLE or flag)
    } else {
        PendingIntent.getActivity(context, id, intent, flag)
    }
}

fun getBroadcast(context: Context?, id: Int, intent: Intent?, flag: Int): PendingIntent {
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
        PendingIntent.getBroadcast(context, id, intent!!, PendingIntent.FLAG_MUTABLE or flag)
    } else {
        PendingIntent.getBroadcast(context, id, intent!!, flag)
    }
}

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.
