title: How to turn off the default vibration of a notification
body: <p>I am using Galaxy Nexus with Android 4.0, I set the silent mode to vibrate in Settings. I use NotificationManager.notify to send the Notification. I don't set Notification.vibrate, I even use myNotification.defaults &amp;= ~Notification.DEFAULT_VIBRATE to disable the vibration. But it still vibrate after calling NotifcationManager.notify.
  Could anyone tell me how to turn off the vibration of a Notification in vibrate mode?</p>
