Notification setAutoCancel(true) doesn't work

问题:

I'm trying to show a notification that has to be deleted when user tap on it. I'm using 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! Where I'm 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.
