AIDL是Android接口定义语言，它可以用于让某个Service与多个应用程序组件之间进行跨进程通信，从而可以实现多个应用程序共享同一个Service的功能。
实现步骤
例：用 A程序去访问 B程序的MyService.java服务
对应步骤详细代码：
MyAidlService.AIDL
interface MyAidlService {
int add(int a, int b);
}
MyService.Java
public class MyService extends Service{
MyAidlService.Stub mBinder = new MyAidlService.Stub() {
@Override
public int add(int a, int b) throws RemoteException {
return a + b;
}
};
@Override
public IBinder onBind(Intent intent) {
return mBinder;
}
@Override
public void onCreate() {
super.onCreate();
}
@Override
public void onDestroy() {
super.onDestroy();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
return super.onStartCommand(intent, flags, startId);
}
}
3.添加action
<service android:name=".MyService">
<intent-filter>
<action android:name="com.xyb.servicetest.MyAidlService"/>
</intent-filter>
</service>
4.拷贝AIDL文件夹
5.A访问B的服务
Intent intent = new Intent("com.xyb.servicetest.MyAidlService");
bindService(intent, connection, BIND_AUTO_CREATE);
private MyAidlService aidlService;
private ServiceConnection connection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
Log.d("onServiceConnected", "onServiceConnected");
aidlService = (MyAidlService) MyAidlService.Stub.asInterface(service);
try {
int sum = aidlService.add(10, 50);//对10和50相加
Log.d("onServiceConnected", sum + "");
} catch (RemoteException e) {
e.printStackTrace();
}
}
@Override
public void onServiceDisconnected(ComponentName name) {
}
};
