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

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);
