使用ADIL访问远程服务

来源：互联网发布：数学建模知乎编辑：程序博客网时间：2024/05/16 10:10

1.新建aidl文件

2.Build->Make Project

在该目录下可以发现生成后的IMyAidlInterface.java文件。

3.新建Service并实现IMyAidlInterface定义的方法，onBind中返回实例。

public class MyRemoteService extends Service {    public MyRemoteService() {    }    IMyAidlInterface.Stub myAidlInterface = new IMyAidlInterface.Stub() {        @Override        public String SayHello(String world) throws RemoteException {            return world;        }    };    @Override    public IBinder onBind(Intent intent) {        // TODO: Return the communication channel to the service.        return myAidlInterface;    }}

4.Manifest 中修改定义

<service    android:name=".MyRemoteService"    android:enabled="true"    android:exported="true"    android:process=":remote"    >    <intent-filter>    <action android:name="my.test.com.servicedemo.MyService" /></intent-filter></service>

5.Activity中调用

楼主下午一直报null因为在bindService后直接调用myAidlInterface 的方法了，此时应该并没有执行完onServiceConnected,

所以最好在onServiceConnected后再调用方法！

intent_aidl = new Intent(this, MyRemoteService.class);

bindService(intent_aidl, aidl_ServiceConnection, BIND_AUTO_CREATE);

private IMyAidlInterface myAidlInterface = null;ServiceConnection aidl_ServiceConnection = new ServiceConnection() {    @Override    public void onServiceConnected(ComponentName componentName, IBinder iBinder) {        Log.i("MainActivity", "ComponentName:"+componentName);        myAidlInterface = (IMyAidlInterface.Stub.asInterface(iBinder)) ;        if(myAidlInterface==null)        Log.i("MainActivity", "myAidlInterface==null");        else        {            try {                String temp=myAidlInterface.SayHello("fuck uuuuuuu!!!!!!");                Toast.makeText(MainActivity.this,temp,Toast.LENGTH_SHORT).show();            } catch (RemoteException e) {                e.printStackTrace();            }        }    }    @Override    public void onServiceDisconnected(ComponentName componentName) {    }};
