【问题描述】：

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();        
}

【解决方案1】：

您正在使用create 创建MediaPlayer，它已经为您调用了prepare。不要再拨打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，查看错误的 logcat 输出会有所帮助。

导入android.media.AudioManager；

android.media.MediaPlayer mediaplayer;
                        mediaplayer = new android.media.MediaPlayer();
                        mediaplayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
                        try {

                            mediaplayer.setDataSource("https://ia801005.us.archive.org/22/items/sslamweb.blogspot.com_201308/Maher%20Zain%20-%20Hold%20My%20Hand%20-%20Official%20Lyrics%20Video.mp3");
                            mediaplayer.prepare();
                        } 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();
                        }

                        mediaplayer.start();

享受.......
