Android: Using AUTO-CANCEL on a notification when your app is running in the background

Question

I have looked at all the other AUTO-CANCEL-not-working questions here, and they all seem to involve mistakes that I am not making. I have tried both

builder         


        

Answer 1

You appear to be missing the PendingIntent and setContentIntent() call. I believe that is required for auto-cancel to work.

Here is some Notification-displaying logic from this sample project that works:

  private void raiseNotification(Intent inbound, File output, Exception e) {
    NotificationCompat.Builder b=new NotificationCompat.Builder(this);

    b.setAutoCancel(true).setDefaults(Notification.DEFAULT_ALL)
     .setWhen(System.currentTimeMillis());

    if (e == null) {
      b.setContentTitle(getString(R.string.download_complete))
       .setContentText(getString(R.string.fun))
       .setSmallIcon(android.R.drawable.stat_sys_download_done)
       .setTicker(getString(R.string.download_complete));

      Intent outbound=new Intent(Intent.ACTION_VIEW);

      outbound.setDataAndType(Uri.fromFile(output), inbound.getType());

      b.setContentIntent(PendingIntent.getActivity(this, 0, outbound, 0));
    }
    else {
      b.setContentTitle(getString(R.string.exception))
       .setContentText(e.getMessage())
       .setSmallIcon(android.R.drawable.stat_notify_error)
       .setTicker(getString(R.string.exception));
    }

    NotificationManager mgr=
        (NotificationManager)getSystemService(NOTIFICATION_SERVICE);

    mgr.notify(NOTIFY_ID, b.build());
  }

Answer 2

So apparently you do need a pending intent.

At Android - notification manager, having a notification without an intent, I found a solution that grabs the current active application as your pending intent (so that you don't have to start your own activity in order to dismiss the notification).

I just added the following two lines of code (right after setting the auto-cancel):

PendingIntent notifyPIntent = 
    PendingIntent.getActivity(getApplicationContext(), 0, new Intent(), 0);     
builder.setContentIntent(notifyPIntent);

It worked great. I would say that if you don't want your activity to restart as a result of the user clicking your notification, then this is your best option.

Hai dear friend if you want to show non cancelable notification(not cancelable for users) for a particular time and after that you need clear it (like the music player) you can use this.

mNotificationBuilder .setSmallIcon(android.R.drawable.btn_plus);
mNotificationBuilder .setContentTitle("My notification");
mNotificationBuilder .setContentText("Notificattion From service");
mNotificationBuilder .setLights(0xFF0000FF, 500, 500);

Notification note = mNotificationBuilder.build();  
note.flags = Notification.FLAG_ONGOING_EVENT; // For Non cancellable notification
mNotificationManager.notify(NOTIFICATION_ID, note);
