android AIDL 實踐之傳遞簡單字串

trace his int ati activity 表示 asi client text

*本demo的server和client寫反了

新建工程client,server

在server端新建aidl文件,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生成java類

在client新建同樣文件,同樣生成java類

*註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文件中註冊

<service android:name=".Myservice" 
 
//這裏表示進程名
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();
//這裏是action
intent.setAction("android.intent.action.RESPOND_VIA_MESSAGE");
//這裏是服務端的包名,本次demo寫反了
intent.setPackage("com.example.client");
ServiceConnection connection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
//這裏獲得實例
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
