android - Android MediaPlayer播放在线(外部)音频

Question

当我单击按钮时，我使用此代码播放在线mp3音频，但它不起作用。

public void play(View v) throws IllegalStateException, IOException{ 
    MediaPlayer em2 =MediaPlayer.create(this, Uri.parse("https://ia801005.us.archive.org/22/items/sslamweb.blogspot.com_201308/Maher%20Zain%20-%20Hold%20My%20Hand%20-%20Official%20Lyrics%20Video.mp3"));
    em2.setAudioStreamType(AudioManager.STREAM_MUSIC);  
    em2.prepare();
    em2.start();        
}

Answer 1

您正在使用MediaPlayer创建create，它已经为您调用prepare。不要再次调用prepare。

public void play(View v) throws IllegalStateException, IOException{ 
    MediaPlayer em2 = MediaPlayer.create(this, Uri.parse("https://ia801005.us.archive.org/22/items/sslamweb.blogspot.com_201308/Maher%20Zain%20-%20Hold%20My%20Hand%20-%20Official%20Lyrics%20Video.mp3"));
    em2.setAudioStreamType(AudioManager.STREAM_MUSIC);
    em2.start();        
}

将来，这将有助于查看错误的logcat输出。
