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：
我在以下设备上遇到过此问题：
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：
