Android：MediaPlayer.prepareAsync（）上的IllegalStateException

Question

我在app中使用Android MediaPlayer在/res/raw文件夹中反复显示.mp4文件作为视频背景。当我在三星和它上面测试时，它运行良好Nexus Android 6.0。

相关代码:(已完成的代码可以找到here）

private void playIntro(SurfaceTexture surfaceTexture) {
    if (player != null) {
        player.release();
        player = null;
    }

    try {
        player = new MediaPlayer();
        AssetFileDescriptor afd = getResources().openRawResourceFd(R.raw.gpoview);
        player.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength());
        player.setOnPreparedListener(this);
    } catch (IOException e) {
        e.printStackTrace();
    }

    player.setSurface(new Surface(surfaceTexture));

    player.setOnVideoSizeChangedListener(new MediaPlayer.OnVideoSizeChangedListener() {
        @Override
        public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
            mVideoWidth = width;
            mVideoHeight = height;
            updateTextureViewSize();
        }
    });

    player.prepareAsync();
}

Crashlytics已针对崩溃报告进行了集成，我收到了许多针对以下崩溃的报告：

它100％来自Android 4.4.4的三星设备，但我找不到重现它的方法。

有关它为何会发生以及如何解决或进一步调试的任何建议？

非常感谢！
