Android AIDL与服务调用 Android AIDL实现与服务相互调用方式

 void getDatas(in byte[] bs);

 void DataWhole(in PackageData data);
}

//接收回调
INotification notification = new INotification.Stub() {
 @Override
 public void Datas(byte[] bs) throws RemoteException {
 Log.d(TAG, "Datas: 收到数据=" + Arrays.toString(bs));//已测试 最大数据1024*1024
 }
 }
 

 //传递回调对象
void setNotification(in INotification Notification);

@Override
public void onServiceConnected(ComponentName name, IBinder service) {
 iAidlInterface = IAidlInterface.Stub.asInterface(service);
 try {
 iAidlInterface.setNotification(notification);
 } catch (RemoteException e) {
 e.printStackTrace();
