Dismiss Ongoing Android Notification Via Action Button Without Opening App

Question

I have an app that has an ongoing notification to help with memorization. I want to be able to dismiss this notification with one of the action button, but I don't want to open the app when the button is hit. I would prefer to use the built-in notification action buttons and not create a RemoteViews object to populate the notification. I saw one post mention using a BroadcastReceiver on this button which is received in my app, and though his tutorial was quite unhelpful, it sounds like this is headed in the right direction.

Intent resultIntent = new Intent(getBaseContext(), Dashboard.class);     TaskStackBuilder stackBuilder = TaskStackBuilder.create(getBaseContext());         stackBuilder.addParentStack(Dashboard.class);         stackBuilder.addNextIntent(resultIntent);         PendingIntent resultPendingIntent =                 stackBuilder.getPendingIntent(                     0,                     PendingIntent.FLAG_UPDATE_CURRENT                 );     Intent cancel = new Intent(getBaseContext(), CancelNotification.class);         stackBuilder.addParentStack(Dashboard.class);         stackBuilder.addNextIntent(cancel);         PendingIntent pendingCancel =                 stackBuilder.getPendingIntent(                     0,                     PendingIntent.FLAG_UPDATE_CURRENT                 );      NotificationCompat.Builder mb = new NotificationCompat.Builder(getBaseContext());         mb.setSmallIcon(R.drawable.cross_icon);         mb.setContentTitle(ref);         mb.setContentText(ver);         mb.setPriority(NotificationCompat.PRIORITY_LOW);         mb.setOngoing(true);         mb.setStyle(new NotificationCompat.BigTextStyle().bigText(ver));         mb.setContentIntent(resultPendingIntent);         mb.addAction(R.drawable.ic_cancel_dark, "Dismiss", pendingCancel);      manager.notify(1, mb.build());

Start with this:

int final NOTIFICATION_ID = 1;  //Create an Intent for the BroadcastReceiver Intent buttonIntent = new Intent(context, ButtonReceiver.class); buttonIntent.putExtra("notificationId",NOTIFICATION_ID);  //Create the PendingIntent PendingIntent btPendingIntent = PendingIntent.getBroadcast(context, 0, buttonIntent,0);  //Pass this PendingIntent to addAction method of Intent Builder NotificationCompat.Builder mb = new NotificationCompat.Builder(getBaseContext()); ..... ..... ..... mb.addAction(R.drawable.ic_Action, "My Action", btPendingIntent); manager.notify(NOTIFICATION_ID, mb.build());   

Create the BroadcastReceiver:

public class ButtonReceiver extends BroadcastReceiver {      @Override     public void onReceive(Context context, Intent intent) {          int notificationId = intent.getIntExtra("notificationId", 0);          // Do what you want were.         ..............         ..............          // if you want cancel notification         NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);         manager.cancel(notificationId);     } }   

If you don´t want show any activity when user click on notification, define the intent passed in setContentIntent in this way:

PendingIntent resultPendingIntent = PendingIntent.getActivity(context,  0, new Intent(), 0); ...... ...... mb.setContentIntent(resultPendingIntent);  

To close notification tray when clicked, call setAutoCancel() with true when building the notification: mb.setAutoCancel(true);
