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

The error message tells you pretty much exactly what to do. Also there are numerous questions on Stackoverflow covering this exact problem. See https://developer.android.com/guide/components/intents-filters#DeclareMutabilityPendingIntent — David Wasser, Feb 13 '22 at 19:26

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.M) {
             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.M) {
         return PendingIntent.getBroadcast(context, id, intent, PendingIntent.FLAG_IMMUTABLE | flag);
     } else {
         return 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.

Have you seen this? Are you using the same MQTT library? https://stackoverflow.com/questions/71155187/android-paho-mqtt-crashes-android-12-targeting-s-version-31-and-above-requi – David Wasser Feb 21 '22 at 09:58

Were you able to fix your problem with the linked solution? – David Wasser Feb 25 '22 at 09:48
yes sir but it is in kotlin format we use java – Cakston MWS Feb 26 '22 at 06:06
What is in Kotlin format? What did you do to fix the problem? – David Wasser Feb 26 '22 at 12:45
sir can u give us a step by step procedure for the fixing of the problem – Cakston MWS Feb 28 '22 at 03:40
@David Wasser Can you expand on your comment to "...probably need to use the MUTABLE flag." with Alarm Manager? I use AlarmManager to fire alarms to trigger Notifications for user due dates and am wondering if I should be using MUTABLE flag. – AJW Apr 05 '22 at 20:17
@AJW Reviewing my comment, I assumed that `AlarmManager` was adding something to the `Intent` when it was triggered, which would imply that `FLAG_MUTABLE` was necessary. However, I just looked again and `AlarmManager` doesn't add anything to the `Intent`, so you should be safe using `FLAG_IMMUTABLE`. Sorry for the confusion. I've edited my answer accordingly. – David Wasser Apr 06 '22 at 09:09
@David Wasser No apology necessary, thanks for reviewing and clarifying. I did see in Android Developer guide that MUTABLE can be used if you have a repeating alarm, to allow the EXTRA_ALARM_COUNT intent extra but only for that use case: https://developer.android.com/guide/components/intents-filters#DeclareMutabilityPendingIntent – AJW Apr 06 '22 at 15:03

@AJW Generally speaking you need to use `FLAG_MUTABLE` if you give the `PendingIntent` to another app and that app needs to add/modify the `Intent` when it ultimately triggers the `PendingIntent`. – David Wasser Apr 06 '22 at 17:35
