Removing notification after click

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..


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


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);

This answer is too much late but specially i write following solution because notification constructor become deprecated so use notification using builder , like following :

 **.setAutoCancel(true)** is used to remove notification on click

and entire notification is like follwoing :

  private void makeNotification(String title,String msg){

    Intent resultIntent = new Intent(this, MasterActivity.class);

    PendingIntent resultPendingIntent =
            PendingIntent.getActivity(
                    this,
                    0,
                    resultIntent,
                    PendingIntent.FLAG_UPDATE_CURRENT
            );

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                    .setContentIntent(resultPendingIntent)
                    .setSmallIcon(R.drawable.ic_launcher)
                    .setContentTitle(title)
                    .setAutoCancel(true)
                    .setContentText(msg);

    int mNotificationId = 001;
    NotificationManager mNotifyMgr =
            (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    mNotifyMgr.notify(mNotificationId, mBuilder.build());

}

Calling this method with title and message you get perfect notification.


Best & simple way is set builder.setAutoCancel(true) it's cancel your notification after clicking on notification. I hope this code help you.

Builder for notification

NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setSmallIcon(android.R.drawable.btn_star);
builder.setContentTitle("This is title of notification");
builder.setContentText("This is a notification Text");
builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));

For open an activity on clicking notification

Intent intent = new Intent(Broadcastdemo.this, ThreadDemo.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 113,intent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);

Show bulder in notification

NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.notify(114, builder.build());

Complete code for show a notification with icon, image, title, description, auto cancel and on click open an activity

public void ShowIntentNotification(View v)
    {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
        builder.setSmallIcon(android.R.drawable.btn_star);
        builder.setContentTitle("This is title of notification");
        builder.setContentText("This is a notification Text");
        builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));

        Intent intent = new Intent(Broadcastdemo.this, ThreadDemo.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 113,intent, PendingIntent.FLAG_UPDATE_CURRENT);

        builder.setContentIntent(pendingIntent);
        builder.setAutoCancel(true);

        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.notify(114, builder.build());

    }
