1. test app를 만들어서 아래 퍼미션 추가하고

<uses-permission android:name="android.permission.MASTER_CLEAR" />
<uses-permission android:name="android.permission.REBOOT" />

코드상

  if (mContext.checkCallingOrSelfPermission("android.permission.MASTER_CLEAR") !=
            PackageManager.PERMISSION_GRANTED) {
        Log.e(TAG, "Permission Denial: can't invoke masterClear from "
                + "pid=" + Binder.getCallingPid() + ", "
                + "uid=" + Binder.getCallingUid());
        return;
    }
  try{
   Power.reboot("reboot");
  }catch(IOException e){
   e.printStackTrace();
   throw new DevicePortingException("Reboot fail");
  }

했으나 아래와 같은 에러 메세지가 나옵니다.

factory reset reboot은 되고 있는데 일반 reboot은 안되고 있습니다.

factory reset reboot은 아래와 같이 하면 됩니다.

                ICheckinService service = ICheckinService.Stub.asInterface(ServiceManager.getService("checkin"));
                if (service != null) {
                    try {
                        // This RPC should never return
                        service.masterClear();
                    } catch (android.os.RemoteException e) {
                        // Intentionally blank - there's nothing we can do here
                        Log.w(TAG, "Unable to invoke ICheckinService.masterClear()");
                    }
                } else {
                    Log.w(TAG, "Unable to locate ICheckinService");
                }

근데 reboot 함수에 string이 모드 인것 같은데, 찾아봐도 recovery 만 보이고 다른 것은 안보이네요...ㅡㅡ..

narmal reboot도 해결 되었네요..

kernel 단에는 narmal reboot을 지원하는데, 플랫폼에서 interface 함수 가 없네요..

ICheckinService interface에 함수를 추가해서 사용하니 되네요..

narmal reboot을 사용할때는 power.reboot("NULL"); 사용하면 되네요...

결국 스스로 해결하셨군요. 안드로이드펍에서 플랫폼쪽은 아직 개척자분들이 더 많으신듯! 결과 공유해주셔서 감사합니다.

ICheckinService 에 함수를 추가 해서 power.reboot("NULL"); 을 사용하려 하니 에러가 뜹니다.

혹시 ICheckinService 에 추가를 어떻게 해야 하나요?

저는 ICheckinService.aidl에 제가 만든 함수 추가 하고.. FallbackCheckinService에서 인터페이스 구현 하여

service.myreboot();을 호출 하였습니다.

           ICheckinService service = ICheckinService.Stub.asInterface(ServiceManager.getService("checkin"));
            if (service != null)
    {
                    try {
                        // This RPC should never return
                        service.myreboot();

                    }
     catch (android.os.RemoteException e)
     {
                        // Intentionally blank - there's nothing we can do here
                        Log.w("dddd", "Unable to invoke ICheckinService.masterClear()");
                    }
                }
   else
   {
                    Log.w("dddd", "Unable to locate ICheckinService");
             }

으라차차

안녕하세요.

reboot 테스트를 하는 중인데.

FallbackCheckinService 에서 Power.reboot("NULL") 을 호출 하는 순간

에뮬레이터가 서 버리네요. ㅜㅜ

reboot 이 성공하면 에뮬레이터가 reboot 이 되나요?? ^^;;
