同时玩两个MediaPlayers，在安卓系统中只玩一个MediaPlayer？

Question

在我的应用程序中，我正在播放"Voice audio Mediaplayer"和"Background music MediaPlayer"，它正在开发安卓lollipop 5.0下的版本。但是，当我检查Lollipop and Android One os时，它并不是同时播放两个媒体播放器。只有“背景媒体播放器”在播放。但当我入住Debug mode时，语音媒体播放器正在播放。

这是我初始化mediaplayer的代码

In onCreate() :

audioManger = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
audioManger.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
audioManger = (AudioManager)getSystemService(Context.AUDIO_SERVICE);

// Intializing Voice audio Mediaplayer

voiceMediaPlayer = new MediaPlayer();
voiceMediaPlayer.setDataSource(bagroundMusicAudioFileName);
voiceMediaPlayer.setLooping(true);
voiceMediaPlayer.prepare();  

// Intializing Background music Mediaplayer

bgMusicMediaPlayer = new MediaPlayer();
bgMusicMediaPlayer.setDataSource(bagroundMusicAudioFileName);
bgMusicMediaPlayer.setLooping(true);
bgMusicMediaPlayer.prepare();

播放按钮onClickListener() :

// Starting Voice and Background MediaPlayers 

if(voiceMediaplayer == null) {
   voiceMediaPlayer = new MediaPlayer();
   voiceMediaPlayer.setDataSource(bagroundMusicAudioFileName);
   voiceMediaPlayer.setLooping(true);
   voiceMediaPlayer.prepare();   
}
voiceMediaPlayer.start();

if(bgMusicMediaPlayer == null) {
   bgMusicMediaPlayer = new MediaPlayer();
   bgMusicMediaPlayer.setDataSource(bagroundMusicAudioFileName);
   bgMusicMediaPlayer.setLooping(true);
   bgMusicMediaPlayer.prepare();     
}
bgMusicMediaPlayer.start();

暂停按钮 onClickListener :

//停止声音&背景媒体播放器按一下暂停按钮

if (voiceMediaPlayer != null && voiceMediaPlayer.isPlaying()) {
    voiceMediaPlayer.reset();
    voiceMediaPlayer.release();
    voiceMediaPlayer = null;
}
if (bgMusicMediaPlayer != null && bgMusicMediaPlayer.isPlaying()) {
    bgMusicMediaPlayer.reset();
    bgMusicMediaPlayer.release();
    bgMusicMediaPlayer = null;
}

当我同时播放两个小型播放器时，我只在Moto(棒棒糖)设备上听到背景音乐，但这个代码是working on below < 5.0(Lollipop) versions。我的手机版本是4.4.4 kitkat，它正在我的设备上工作。

我的密码有什么问题吗？如何在棒棒糖中一次播放2 MediaPlayers？

最后从Playing multiple songs with MediaPlayer at the same time: only one is really playing中得到了解决方案

谢谢你们救了我的时间。
