clear missed calls and clear notification from android bar

Question

Using this code I managed to mark all missed calls as read:

ContentValues values = new ContentValues();
        values.put(Calls.NEW, 0);
        if (android.os.         


        

Answer 1

How can I also clear the notification bar for calls in android?

You don't. That Notification is put there by another app, and you have no means of controlling whether that Notification is displayed, short of building a ROM mod that changes the behavior of that other app.

UPDATE: Since this answer was originally written, NotificationListenerService was added and can clear notifications, but only on Android 4.3+.
