Android MediaPlayer不能在Android 5.1.1的Galaxy S6上播放

Question

我看到一个特定于运行Android 5.1.1的Galaxy S6的问题.我正在使用MediaPlayer播放音频流,并且在设备和Android版本的这种特定配置上,它无法达到onPrepared方法,因此永远无法播放.

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mAndroidPlayer = new MediaPlayer();

        mAndroidPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {
            @Override
            public boolean onError(MediaPlayer mediaPlayer, int i, int i1) {
                System.out.print("ERROR " + i);
                return false;
            }
        });

        mAndroidPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mediaPlayer) {
                System.out.println("PREPARED");
                mAndroidPlayer.start();
            }
        });

        mAndroidPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

        try {
            mAndroidPlayer.setDataSource("http://live.radioart.com/fFilm_scores.mp3");
        } catch (IOException e) {
            e.printStackTrace();
        }

        try {
            mAndroidPlayer.prepareAsync();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        }
    }

只是为了重新迭代,它适用于所有其他设备和Android版本.

以下是从控制台输出:

Answer 1

这是一个部分解决方案,但在我看来,它是最常用的解决方案.MediaPlayer很久以前就已经创建了,因此我们并不像我们想要的那样灵活.我已经使用Exoplayer一年了,最后一个版本只带有音频播放功能.所以我想如果你改变你的音频播放器的实现来使用Exoplayer它将解决大多数问题和以后的问题.

Exoplayer是谷歌开发人员的强大播放器,可作为外部库,因此您无需管理某些Android版本的错误实施.
