记录下用广播方式开机启动service或activity，当然还有一种在init.rc中注册服务，待下次研究O(∩_∩)O。
当Android系统完成BOOT阶段之后，就会发送一条名为 ACTION_BOOT_COMPLETED 的广播，我们便可在一个BroadcastReceiver中捕获这条广播，然后启动我们的Activity或者Service，当然要注意的是，我们的 application必须具有捕获该广播的权限：
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

} 这里已基本实现开机启动service,并且使用jni从c层传递消息，到java处理。
