problem with notifications

the notification works fine, but when I press it, I create another activiti instead of opening the one that is already in memory, this causes the audio to continue playing, but the new activitie is not able to interact with that audio (let's say I have MainActivitie and when I open the notification with the app in the background I create another MainActivitie). I would like that when pressing the notification, or the activitie that is in memory is reopened, another option would be to finalize the app, the two options are valid but they are not carried out. My code:

Android architecture [closed] How to identify a word within a String and replace it completely with another symbol (#)?

score 0 · Answer 1

You are opening MainActivity again since you have defined a PendingIntent that defines open MainActivity from MainActivity , you could avoid setting this PendingIntent :

 Intent i=new Intent(MainActivity.this, MainActivity.class);
 PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0, i, 0);

If you want to open only the application, by clicking on the notification , define the PendingIntent with the following Flags:

Intent iNormal = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, msgId | MASK_ACTION_OPEN, iNormal, PendingIntent.FLAG_UPDATE_CURRENT);

and configure it to your Notification:

 mBuilder = new NotificationCompat.Builder(getApplicationContext())
                .setContentIntent(pendingIntent)
                ...
                ...
