Android MediaPlayer未使用Android 5.1.1在Galaxy S6上播放

我看到一个问题是运行Android 5.1.1的Galaxy S6特有的。我使用MediaPlayer播放音频流，在这个特定的设备配置和Android版本上，它无法达到onPrepared方法，因此从不播放

@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();
        }
    }

只是重复一下，它可以在所有其他设备和Android版本上正常工作

以下是控制台的输出：

这是一个局部解决方案，但在我看来，它是最持久的解决方案。MediaPlayer是很久以前创建的，因此没有我们想要的灵活性。我已经用了一年了，上一个版本只有音频播放。所以我想，若你们将你们的音频播放器的实现改为使用Exoplayer，那个么它将解决大多数问题和以后的问题

Exoplayer是google开发者提供的一款功能强大的播放器，可作为外部库使用，因此您不必在某些Android版本上管理错误的实现

TBH，我不知道为什么会发生这种情况。回到过去，三星的设备有一个bug，它没有在

VideoView

上调用

onPrepareListener

。如果这只发生在S6上，您可以排除添加此侦听器，并在

OnBufferingUpdateListener

内的缓冲超过某个阈值（可能是100%）时调用

.start（）

，因为您是从URI流式传输的。OnBufferingUpdateListener也永远不会被调用。这会将事情复杂化到一个新的级别。启动单独的线程/asyntask，检查缓冲百分比或启动递归处理程序，但要小心。使用控制台的输出进行更新。这确实令人沮丧。我已经有一个应用程序在野外运行了大约一年，它工作得很好。现在，我必须考虑改变我的整个实现，因为三星不能把他们的SH**组合在一起？（当然，我现在是一个比当时更好的开发人员，我本可以让自己更轻松……）我遇到了与OP相同的S6问题，ExoPlayer解决了它。我认为这不是一个有效的解决方案。它建议使用完全其他的东西，而不是提供一个具体的解决办法。它认为该框架是“旧的”，无法使用。评论？@anthonymonori你是对的，这不是一个合适的解决方案，但我们已经到了谷歌在Youtube上使用Exoplayer的地步。对我来说，每个供应商的编解码器都有一些问题，MediaPlayer也有一些问题。此解决方案通过使用不同的独立播放器来解决与MediaPlayer相关的问题。
