我计划通过流式传输几个本地互联网收音机来开发一个 Android 应用程序。为此,我正在使用 Android 的MediaPlayer
对象并使用setDataSource
方法。但是,我失败了,因为它没有像我预期的那样流式传输。但是,如果我将其设置setDataSource
为真正的 mp3 资源,它就可以工作。
仅供参考,我还在uses-permission
AndroidManifest.xml 文件上设置如下,
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
这是我在此应用程序MainActivity.java中使用的代码,
package com.example.saralfm;
import java.io.IOException;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnPreparedListener;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final MediaPlayer mp = new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
//Its working
//mp.setDataSource("http://download.tamiltunes.com/songs/__P_T_By_Movies/Saguni%20%282012%29/Manasellam%20Mazhaiye%20-%20TamilWire.com.mp3");
//Its not working
mp.setDataSource("http://www.onlineradios.in/tamil-radio-from-india/#aahaa-91_9-fm-chennai/");
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mp.setOnPreparedListener(new OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer arg0) {
// TODO Auto-generated method stub
mp.start();
}});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
我对 Android 操作系统很陌生。请帮帮我。
