android AIDL 實踐之傳遞簡單字串

標籤：sage   generate   length   toast   one   bind   rtc   工程   imp   

*本demo的server和client寫反了

建立工程client，server在server端建立aidl檔案，內容：

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

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

interface IMyAidlInterface {

    String getString();
}

Make project自動在server\build\generated\source\aidl\debug\com\example\server產生java類

在client建立同樣檔案，同樣產生java類

*注意兩個的包名要一致

在server編寫service服務

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檔案中註冊

<service android:name=".Myservice" 

//這裡表示進程名

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

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

 

在client端寫代碼綁定service

public void bindMyservice()
{
    Intent intent = new Intent();
    //這裡是action

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

//這裡是服務端的包名，本次demo寫反了
    intent.setPackage("com.example.client");
    ServiceConnection connection = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
//這裡獲得執行個體
            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
