android AIDL 实践之传递简单字串

满堂花醉三千客，一剑霜寒十四州。这篇文章主要讲述android AIDL 实践之传递简单字串相关的知识，希望能为你提供帮助。
*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：【android AIDL 实践之传递简单字串】// 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);
}
