数据流程

客户端进程 实例化

private ISufadiWakeupWatcherService mISufadiWakeupWatcherService;mISufadiWakeupWatcherService = ISufadiWakeupWatcherService.Stub.asInterface(ServiceManager.getService("sufadi_wakeupwatcher"));

客户端进程 代理接口传递数据

    mISufadiWakeupWatcherService.wakeUpByStartProcessLocked(sufadiAMSBuf.toString());

服务端进程 接受和处理数据

public class SufadiPowerSaveService extends Service {private ISufadiWakeupWatcherCallback mISufadiWakeupWatcherCallback = new ISufadiWakeupWatcherCallback.Stub() {
