公共静态最后弦乐  ACTION_SHUTDOWN

自:API级别4广播事件:  设备正在关闭。这是  播放时,该设备是  关闭(完全关闭,不  睡眠)。当广播是  完成后,最终关闭将  继续和所有未保存的数据丢失。  应用程序通常不需要处理  此,由于前台活动  将被暂停为好。这是一个  只能发送保护意图  由系统

Since: API Level 4 Broadcast Action: Device is shutting down. This is broadcast when the device is being shut down (completely turned off, not sleeping). Once the broadcast is complete, the final shutdown will proceed and all unsaved data lost. Apps will not normally need to handle this, since the foreground activity will be paused as well. This is a protected intent that can only be sent by the system.

常数值:  android.intent.action.ACTION_SHUTDOWN

Constant Value: "android.intent.action.ACTION_SHUTDOWN"

这似乎是吗?我只是用Google搜索你的命令,这是标准的广播操作列表中。 :)

This would appear to be it? I just Googled your command and it was on the Standard Broadcast Actions list. :)
