The following parameters are displayed in the top notification bar of the small icon, the text next to the small icon (briefly displayed, automatically disappear) system current time (do not understand what is the use of this)
Notification.defaults=notification.default_all;
This is the setting notification whether the sound or vibration is played simultaneously, and the sound is Notification.default_sound
Vibration is notification.default_vibrate;
Light is notification.default_lights, and I don't seem to have any reaction on my milestone.
All for Notification.default_all
If it is vibrating or all, you must add the vibration permission in the Androidmanifest.xml
Pendingintent pt=pendingintent.getactivity (this, 0, new Intent (This,main.class), 0);
Click on the notification after the action, here is back to main this acticity
Notification.setlatesteventinfo (THIS,TITLE,CONTENT,PT);
Nm.notify (notification_id, notification);

}
}
