using namespace android;
class MyService :public IBinder::DeathRecipient{void MyService::binderDied(const wp<IBinder>& who) {//可以释放相关资源}void MyService ::setCallback(const sp<MyCallback>& cb) {::android::IInterface::asBinder(cb)->linkToDeath(this);}
}

using namespace android;
class MyClient :public IBinder::DeathRecipient{void  MyClient ::binderDied(const wp<IBinder>& who) {   IInterface::asBinder(mService)->unlinkToDeath(this);//这里可做重新申请获取service。}void  MyClient ::getService() {mService = getService(String16("XXXX"));IInterface::asBinder(mService)->linkToDeath(this);}
}
