客戶端是Android程式和服務端採用C++程式編寫 客戶端新建一個Android程式，在包名 com.example.client3下有檔案，如下 MainActivity.java ---------------------------------------------------------------------------------------------------------- package com.example.client3; import android.app.Activity; import android.os.Bundle; import android.os.IBinder; import android.os.Parcel; import android.os.RemoteException;

import android.os.ServiceManager; import android.util.Log; public class MainActivity extends Activity { private static final String TAG = MainActivity.class.getSimpleName(); private static final java.lang.String DESCRIPTOR = "sample.hello"; private staticfinalintFUNC_CALLFUNCTION = 1;      @Override

protected void onCreate(Bundle savedInstanceState) {           super.onCreate(savedInstanceState);           Log.i(TAG, "Client oncreate ");           Parcel _data = Parcel.obtain();           Parcel _reply = Parcel.obtain();           IBinder b = ServiceManager.getService(DESCRIPTOR);  try {               _data.writeInterfaceToken(DESCRIPTOR);

              b.transact(FUNC_CALLFUNCTION, _data, _reply, 0);               _reply.readException();               _reply.readInt();           } catch (RemoteException e) {  // TODO Auto-generated catch block               e.printStackTrace();           } finally {               _reply.recycle();               _data.recycle();           }      } }

1、先編譯好服務，然後將服務跑起來 2、執行android程式，抓log
