使用移动数据而不是wifi在android中播放音乐

Question

我开发了一个从url流式传输的音乐应用程序。它似乎在wifi连接上工作得很好，但在移动3G上没有缓冲（即歌曲不播放）。用于播放/暂停按钮的ClickListener内的代码是-

private OnClickListener TumHiHo = new OnClickListener() {
    @Override
    public void onClick(View v) {
        if (!playPauseTumHiHo) {
            tumhihobtn.setBackgroundResource(R.drawable.button_pause);
            if (initialStartTumHiHo)
            {  mediaPlayer.stop();
            mediaPlayer.reset();
            initialStartSunRahaHaiNa=true;
            initialStartTumHiHo=false;
            new Player()
                        .execute("http://sound30.mp3slash.net/indian/aashiqui2/[Songs.PK]%20Aashiqui%202%20-%2001%20-%20Tum%20Hi%20Ho.mp3");
            loadDocTumHiHo();
            chkStatus();
            }else {
                if (!mediaPlayer.isPlaying())
                    mediaPlayer.start();
            }
            playPauseTumHiHo = true;
        } else {
            tumhihobtn.setBackgroundResource(R.drawable.button_play);
            if (mediaPlayer.isPlaying())
                mediaPlayer.pause();
            playPauseTumHiHo = false;
        }
    }
};

chkStatus（）用于测试用户是在使用移动数据还是wifi。

清单文件具有-

 <uses-permission android:name="android.permission.INTERNET"/>
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

显示的logcat为-

我不知道问题出在我手机的网络上还是应用程序上。如果是应用程序，请告诉我哪里可能出了问题。提前谢谢。

尝试用您的方法替换此代码

new Player().execute("http://sound30.mp3slash.net/indian/aashiqui2/[Songs.PK] Aashiqui 2 - 01 - Tum Hi Ho.mp3");
