报错代码块：
private MediaPlayer createMediaPlayer(final String path) {

try {
if (path.startsWith("/")) {
final FileInputStream fis = new FileInputStream(path);
mediaPlayer.setDataSource(fis.getFD());
fis.close();

mediaPlayer.setDataSource(assetFileDescriptor.getFileDescriptor(), assetFileDescriptor.getStartOffset(), assetFileDescriptor.getLength());
}
}
mediaPlayer.prepare();
mediaPlayer.setVolume(this.mLeftVolume, this.mRightVolume);
} catch (final Exception e) {
mediaPlayer = null;
Log.e(Cocos2dxMusic.TAG, "error: " + e.getMessage(), e);
}
return mediaPlayer;

主要报错代码行：
报错：org.cocos2dx.lib.Cocos2dxMusic.createMediaPlayer(Cocos2dxMusic.java:285)
代码：final AssetFileDescriptor assetFileDescriptor = this.mContext.getAssets().openFd(path);
说明：
createMediaPlayer(final String path)方法中的参数（path）为空；
音乐路径：Resources/res/Sounds/background.mp3；
版本：cocos2dx 3.15
