Removing notification after click

Question

I just started working with notifications and now I'm trying to remove the notification and launch the app once the notification has been tapped in the notificationcenter.

I tried to work with the following code:

import android.app.NotificationManager;  public class ExpandNotification {      private int NOTIFICATION = 546;      private NotificationManager mNM;       public void onCreate() {         mNM.cancel(NOTIFICATION);         setContentView(R.layout.activity_on);         //Toast.makeText(this, "stopped service", Toast.LENGTH_SHORT).show();     } 

I think this code executes the other class when tapped?

PendingIntent contentIntent = PendingIntent.getActivity(this, REQUEST_CODE, new Intent(this, ExpandNotification.class), 0); 

However the notification doesn't go away, nor does the application launch. But I'm able to swipe it to left or right to remove it but that's not what I want..

Answer 1

To get the same effect using Notification.Builder or NotificationCompat.Builder call setAutoCancel(true) on the Builder instance.

Answer 2

Use the flag Notification.FLAG_AUTO_CANCEL

Notification notification = new Notification(icon, tickerText, when); notification.setLatestEventInfo(context, contentTitle, contentText, pendingIntent);  // Cancel the notification after its selected notification.flags |= Notification.FLAG_AUTO_CANCEL; 

and to launch the app:

NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);  // Create a new intent which will be fired if you click on the notification Intent intent = new Intent(context, App.class);  // Attach the intent to a pending intent PendingIntent pendingIntent = PendingIntent.getActivity(context, intent_id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
