/********************************************************************************

* Android AIDL自动生成Java文件测试

* 说明：

* 知道有aidl这东西已经挺久了，但是一直没有花时间来系统了解一下其工作机制，现在

* 花点时间一点一点验证一下其功能。

二、cat forService.aidl

package com.example.aidltest.aidl;

import com.example.aidltest.aidl.forActivity;interfaceforService {voidregisterTestCall(forActivity cb);voidinvokCallBack();

}

三、cat forService.java/** This file is auto-generated. DO NOT MODIFY.

publicStub() {this.attachInterface(this, DESCRIPTOR);

}/**

//在使用的时候经常会看到这一部分的内容

}//AIDL中自定义的方法，没有实现

public voidregisterTestCall(com.example.aidltest.aidl.forActivity cb)

}

四、cat MainActivity.javapublic classMainActivity extends ActionBarActivity {

@Overrideprotected voidonCreate(Bundle savedInstanceState) {

......newforService.Stub() {

@Overridepublic voidregisterTestCall(forActivity cb) throws RemoteException {//TODO Auto-generated method stub

}

@Overridepublic voidinvokCallBack() throws RemoteException {//TODO Auto-generated method stub

}

};

......

}
