Notification setAutoCancel(true) doesn't work

问题

I'm trying to show a notification that is removed when the user taps on it. I'm using the NotificationCompat class to build my notification and I call setAutoCancel(true) on my builder. This is the piece of code:

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.ic_launcher)
        .setContentTitle("title")
        .setAutoCancel(true)
        .setContentText("content");
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, mBuilder.build());

The notification is correctly added but when I tap on it nothing happens! What am I doing wrong?

Using setContentIntent should solve your problem:

.setContentIntent(PendingIntent.getActivity(this, 0, new Intent(), 0));

In your example:

NotificationCompat.Builder mBuilder= new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.notification_icon)
        .setContentTitle("title")
        .setAutoCancel(true)
        .setContentText("content")
        .setContentIntent(PendingIntent.getActivity(this, 0, new Intent(), 0));
NotificationManager notificationManager= (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, mBuilder.build());

Often you might want to direct the user to the relevant content and so might replace 'new Intent()' with something else.

I uploaded a demo to github.

I know an answer has already been accepted, but I had the same problem with a different solution so I will share it here.

For me, I was using the same NotificationCompat.Builder object to create a notification which called setOngoing(true). This was for an upload progress notification which should not be removed while working.

Anyways, after the task was complete, I called setAutoCancel(true) but the notification was still not swiping away. What I had to do also was call setOngoing(false).

It seems pretty obvious now, but it might save someone else some time in the future.
