Android AIDL和远程Service调用（二）

5、其中用到的IServicePlayer.aidl,放在和Java文件相同的包中，内容如下：

java代码：

package eoe.demo; 
interface IServicePlayer{ 
void play(); 
void pause(); 
void stop(); 
int getDuration(); 
int getCurrentPosition(); 
void seekTo(int current); 
boolean setLoop(boolean loop); 
} 

一旦你写好了这个IServicePlayer.aidl文件，ADT会自动帮你在gen目录下生成IServicePlayer.java文件

6、MusicService.java的内容如下：

java代码：

package eoe.demo; 

import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;

public class MusicService extends Service {
	String tag = "yao";
	public static MediaPlayer mPlayer;
	public boolean isPause = false;
	IServicePlayer.Stub stub = new IServicePlayer.Stub() {
		@Override
		public void play() throws RemoteException {
			mPlayer.start();
		}
		@Override
			public void pause() throws RemoteException {
			mPlayer.pause();
		}
		@Override
		public void stop() throws RemoteException {
			mPlayer.stop();
		}
		@Override
		public int getDuration() throws RemoteException {
			return mPlayer.getDuration();
		}
		@Override
		public int getCurrentPosition() throws RemoteException {
			return mPlayer.getCurrentPosition();
		}
		@Override
		public void seekTo(int current) throws RemoteException {
			mPlayer.seekTo(current);
		}
		@Override 
		public boolean setLoop(boolean loop) throws RemoteException { 
			return false;
		}
	};
	@Override
	public void onCreate() {
		Log.i(tag, "MusicService onCreate()");
		mPlayer = MediaPlayer.create(getApplicationContext(), ElfPlayerUtil.getFileinSD("wind.mp3"));
	}
	@Override
	public IBinder onBind(Intent intent) {
		return stub;
	}
}
