我開發了一個音樂應用程序，從一個URL流。看來工作在WiFi連接正常，但播放/暫停按鈕是 -流動音樂在Android使用移動數據，而不是WiFi
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;
}
}
};
的chkStatus（）是測試是否在移動3G不緩衝（即歌不玩了）。該代碼中onClickListener用戶正在使用移動數據或WiFi。

我不知道這個問題是否與我的移動網絡或應用程序。如果是應用程序，請告訴我哪裏可能會出錯。提前致謝。
