java - Android 媒体播放器 URL 音频

Question

我正在创建一个将从 URL 传输音频的应用程序。但我收到错误。
这是代码:

   MediaPlayer mediaPlayer = new MediaPlayer();
    try {
        mediaPlayer.setDataSource("http://http://www.glowingpigs.com/audioclip/10.mp3");
    } 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();
    }
    try {
        mediaPlayer.prepare();
    } catch (IllegalStateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    mediaPlayer.start();

这是错误:

您可以删除不需要的错误。

Answer 1

我认为您输错了网址。

将 http://www.glowingpigs.com/audioclip/10.mp3
替换为 http://www.glowingpigs.com/audioclip/10.mp3 .

如果你看MediaPlayer class ，您可以看到抛出的错误类型是什么。

在你的情况下是:

public static final int MEDIA_ERROR_IO
File or network related operation errors.
Constant Value: -1004 (0xfffffc14)
