android AIDL 实践之传递简单字串

*本demo的server和client写反了

新建工程client，server

在server端新建aidl文件，内容：

// IMyAidlInterface.aidl
package com.example.server;

// Declare any non-default types here with import statements

interface IMyAidlInterface {

    String getString();
}

Make project自动在server\build\generated\source\aidl\debug\com\example\server生成java类

在client新建同样文件，同样生成java类

*注意两个的包名要一致

在server编写service服务

package com.example.client;



import android.app.Service;

import android.content.Intent;

import android.os.IBinder;

import android.os.RemoteException;

import android.support.annotation.Nullable;

import android.util.Log;



import com.example.server.IMyAidlInterface;



/**

 * Created by luozhenlonghp on 2017/5/13.

 */



public class Myservice extends Service {

    public static final String TAG = "Myservice";

    @Nullable

    @Override

    public IBinder onBind(Intent intent) {

        return result;

    }



    IMyAidlInterface.Stub result = new IMyAidlInterface.Stub(){



        @Override

        public String getString() throws RemoteException {

            return "you get it";

        }

    };



    @Override

    public void onCreate() {

        Log.i(TAG,"onCreate is called");

        super.onCreate();

    }



    @Override

    public int onStartCommand(Intent intent, int flags, int startId) {

        Log.i(TAG,"onStartCommand is called");

        return super.onStartCommand(intent, flags, startId);

    }

}

在menifest文件中注册

<service android:name=".Myservice" 

//这里表示进程名

android:process="com.test.myservice">



    <intent-filter>

        <action android:name="android.intent.action.RESPOND_VIA_MESSAGE"></action>

    </intent-filter>

</service>

在client端写代码绑定service

public void bindMyservice()

{

    Intent intent = new Intent();

    //这里是action

intent.setAction("android.intent.action.RESPOND_VIA_MESSAGE");

//这里是服务端的包名，本次demo写反了

    intent.setPackage("com.example.client");

    ServiceConnection connection = new ServiceConnection() {

        @Override

        public void onServiceConnected(ComponentName name, IBinder service) {

//这里获得实例

            iMyAidlInterface = IMyAidlInterface.Stub.asInterface(service);



            try {

                String result = iMyAidlInterface.getString();

                Toast.makeText(MainActivity.this,result , Toast.LENGTH_SHORT).show();

            } catch (RemoteException e) {

                e.printStackTrace();

            }





        }



        @Override

        public void onServiceDisconnected(ComponentName name) {



        }

    };



    bindService(intent,connection,BIND_AUTO_CREATE);

}

大功告成
