Android MarshMallow MediaPlayer过早关闭

我一直在使用 MarshMallow 上的MediaPlayer播放音频文件时出现问题，因为它很快就停止了一段时间。

音频文件是 .wav 文件，长度不超过3秒。它具有以下属性：

  • 编解码器：PCM S16 LE（araw）
  • 频道：Mono
  • 采样率：8000 Hz
  • 每个样本的位数：16

我在以下设备上遇到过此问题：

  • OnePlus One - Android版本：6.0.1
  • Nexus 6 - Android版本：6.0.1
  • Nexus 5 - Android版本：6.0.1

相同的代码适用于以前版本的Android。

从最初看起来，由于NuPlayer的实施和AwesomePlayer的删除，它看起来很像。在 Lollipop 中，在开发人员设置中可选择使用NuPlayer。

有没有人经历过这个？你做了什么来解决这个问题？

我的代码只需执行以下操作：

String mAudioFilePath = "path to audio file"
MediaPlayer player = new MediaPlayer();
player.setWakeMode(getActivity(), PowerManager.PARTIAL_WAKE_LOCK);
player.reset();
player.setDataSource(mAudioFilePath);
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                                @Override
                                public void onPrepared(MediaPlayer mp) {
                                    mp.start();
                                    audioSeekBar.setProgress(0);
                                    audioSeekBar.setMax(100);
                                    updateProgressBar();

                                }
                            });
player.prepareAsync();

updateProgressBar() - 更新audioSeekBar并停止使用以下内容更新SeekBar：

player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mp) {
                mHandler.removeCallbacks(mUpdateTimeTask);
                audioSeekBar.setProgress(0);
                audioSeekBar.setMax(100);
                player.stop();
                player.reset();

            }
});

我得到以下堆栈跟踪：
