Android 声音：应已设置字幕控制器

我有一个奇怪的问题，我的音频文件有时播放，有时不播放

问题是，当LogCat决定不玩时，它会给我以下信息：

Should have subtitle controller already set

这是我播放声音的代码：

public void sound(){
    //store the sound file name
    String filename=f_fruit_ar.m4a;

    //All sounds stored in assets folder
    try{
        AssetFileDescriptor afd = getAssets().openFd(filename);
        MediaPlayer player = new MediaPlayer();
        player.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
        player.prepare();
        player.start();         
        }
        });
    }
    catch (Exception e) {
    e.printStackTrace();
    }
}

我认为问题在于玩家玩完游戏后你没有释放资源，你需要释放资源

示例：

public void sound(){
    //store the sound file name
    String filename=f_fruit_ar.m4a;

    //All sounds stored in assets folder
    try{
        AssetFileDescriptor afd = getAssets().openFd(filename);
        MediaPlayer player = new MediaPlayer();
        player.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
        player.prepare();
        player.start();
        player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
        public void onCompletion(MediaPlayer mp) {
        player.release();
        }
});
    }
    catch (Exception e) {
        e.printStackTrace();
    }
}
