AIDL

In the interface file AIDLFunctions.aidl, we define a method show

interface AidlFunctions{
    void show();
}
Server:
The use of AIDL requires a Service, so we also declare a Service on the server

public class AIDLService extends Service { //stub is     AidlFunctions.Stub binder
automatically generated by the system ;     @Override     public void onCreate() {         // TODO Auto-generated method stub         super.onCreate();     }     @Override     public IBinder onBind(Intent intent) {         // TODO Auto -generated method stub         binder = new AidlFunctions.Stub() {             @Override             //Here is the implementation of the method we declared in the interface















            public void show() throws RemoteException {
                // TODO Auto-generated method stub
                System.out.println("--------------------收到----------------------");
            }
        };
        return binder;
    }  
}
在AndroidManifest声明Service

        <service android:name="com.example.androidaidl.AIDLService">
            <intent-filter>
                <action android:name="com.example.androidaidl.AIDLService" />
            </intent-filter>
        </service>
客户端：

//绑定服务，要用到ServiceConnection
private ServiceConnection serviceConnection;
//Custom interface, same as server
private AidlFunctions aidlFunctions;

serviceConnection = new ServiceConnection() {

    @Override
    public void onServiceDisconnected(ComponentName name) {
        // TODO Auto-generated method stub
        System.out.println("--------------------ServiceDisconnected----------------------");
    }

    @Override
    public void onServiceConnected(ComponentName name, IBinder service) {
        // TODO Auto-generated method stub
        System.out.println("--------------------ServiceConnected----------------------");
        aidlFunctions = AidlFunctions.Stub.asInterface(service);
    }
};
Intent intent = new Intent("com.example.androidaidl.AIDLService");
bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE);
//调用show方法
try {
    aidlFunctions.show();
} catch (RemoteException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
