从4.2.1开始：

Notification vibration improvements: [DO NOT MERGE]

• When notifications vibrate as a fallback (that is, because they want to play a sound but the device is in vibrate mode), this no longer requires the VIBRATE permission.
• As a bonus, if your notifications use DEFAULT_VIBRATE, you don't need the VIBRATE permission either.
• If you specify a custom vibration pattern, you'll still need the VIBRATE permission for that.
• Notifications vibrating in fallback mode use same vibration pattern but can be changed easily in future.
• The DEFAULT_VIBRATE and fallback vibrate patterns are now specified in config.xml.
