MediaPlayer损坏的URL问题

Question

我在项目中使用简单的MediaPlayer收听音频。

如果音频链接断开或不正确，我的应用程序将冻结（一段时间后崩溃）。

MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
    mediaPlayer.setDataSource("my audio link");
} catch (IOException e) {
    e.printStackTrace();
}
try {
    mediaPlayer.prepare();
} catch (IOException e) {
    e.printStackTrace();
}
mediaPlayer.start();

谢谢您的帮助。

Answer 1

尝试替换

mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC)

使用以下代码

final AudioAttributes audioAttributes =new AudioAttributes
            .Builder()
            .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
            .build();
mediaPlayer.setAudioAttributes(audioAttributes);

您可以将AudioAttributes类型更改为所需的类型。请参阅文档。https://developer.android.com/reference/android/media/AudioAttributes

原因为setAudioStreamType为折旧方法。参见https://developer.android.com/reference/android/media/MediaPlayer
