MediaPlayer 损坏 url 问题

Question

我在我的项目中使用简单的 MediaPlayer 来收听我的音频。

如果音频 link 损坏或不正确，我的应用程序会冻结（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();

感谢您的帮助。

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 类型更改为您想要的类型。请参阅文档。 https://developer.android.com/reference/android/media/AudioAttributes

原因是 setAudioStreamType 是贬值方法。参见 https://developer.android.com/reference/android/media/MediaPlayer
