Aidl

1,创建aidl的文件

package com.sdingba.aidl

interface ISDingBaAidl{

//计算2个数的和

int add(int num1,int num2);

}

2，创建类继承service

IRemoteService extends Service{

@Override

public IBinder onBind(Intent intent) {

return new MiddlePerson();

}

private IBinder iBinder = new ISDingBaAidl.Stub{

@Override

public int add(int num1,int num2){

return num1+num2;

}

}

}

3,声明：

<service android:name="com.sdingba.aidl.IRemoteService">

创建客户端app

1,在客服端差创建文件夹，吧服务端的aidl文件拷贝到文件夹中。

2，远程绑定的代码：
Intent inten = new Intent();

//新版本必须 显示Intent显示绑定服务

intent.setComponent(new CompeoentName("com.sdingba.aidl","com.sdingba.aidl.IRemoteService"));

bindService(intent,conn,Context.BIND_AUTO_CREATE);

3,创建conn

private ServiceConnection conn = new ServiceConnection(){

@Override

public void onServiceConnected(){

//拿到了远程的服务

ISDingBaAidl issdingba =   ISDingBaAidl.Stub.adInterface(service);

}

@Override

public void onServiceDisconnected(){

issdingba = null;//回收资源

}

}

    3.调用函数

    

issdingba.add(num1,num2);

    4,解除绑定
    

onDestroy(){
                unbindService(conn);
        }

服务app：

1：IMiddlePerson.aidl

package com.sdingba.remoteservice;

interface IMiddlePerson {
/**
* 调用服务里面的方法
*/
void callMethodInService();
}

2：RemoteService。java

public class RemoteService extends Service {

@Override
public void onCreate() {
System.out.println("远程服务被创建了。。。");
super.onCreate();
}

@Override
public void onDestroy() {
System.out.println("远程服务被销毁了。");
super.onDestroy();
}

@Override
public IBinder onBind(Intent intent) {
return new MiddlePerson();
}

private void methodInService(){
System.out.println("我是远程服务的方法，我被调用了。。。。");
}

//1.创建一个中间人  远程服务继承的是ipc的一个实现类
private class MiddlePerson extends IMiddlePerson.Stub{
@Override
public void callMethodInService() {
methodInService();
}

}

}

3,:XML文件；配置

<service android:name="com.sdingba.remoteservice.RemoteService">
<intent-filter >
<!-- 为了方便别的程序用，所以定义一个action来使得别的程序可以调用 -->
<action android:name="com.sdingba.remoteservice"/>
</intent-filter>
</service>

绑定服务app

**1,拷贝aidl文件到目录

2：MainActivity。java**

public class MainActivity extends Activity {
private MyConn conn;
private IMiddlePerson iMp;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

/**
* 绑定远程服务
* @param view
*/
public void bind(View view){
Intent intent = new Intent();
intent.setAction("com.sdingba.remoteservice");
conn = new MyConn();
bindService(intent, conn, BIND_AUTO_CREATE);
}

private class MyConn implements ServiceConnection{
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
//得到的方式和刚才不同，这个为远程绑定、、得到服务
iMp = IMiddlePerson.Stub.asInterface(service);
}

@Override
public void onServiceDisconnected(ComponentName name) {

}
}

public void call(View view){
try {
//调用到远程服务的方法。。在远程服务中写的方法
iMp.callMethodInService();
} catch (RemoteException e) {
e.printStackTrace();
}
}
@Override
protected void onDestroy() {
unbindService(conn);
super.onDestroy();
}
}
