我在我的应用程序中使用下面的代码来播放声音。但我不能玩它。有什么问题 ？？

代码：

public void playSound(int resources){
    try{
        boolean mStartPlaying = true;
        MediaPlayer  mPlayer=null;
        if (mStartPlaying==true){
            mPlayer = new MediaPlayer();

            Uri uri = Uri.parse("android.resource://MY_PACKAGE/" + resources);
            mPlayer.setDataSource(getApplicationContext(),uri);
            mPlayer.prepare();
            mPlayer.start();
        } 
        else{
            mPlayer.release();
            mPlayer = null;
        }
        mStartPlaying = !mStartPlaying;
    }
    catch (IOException e){
        Log.e(LOG_TAG, "prepare() failed");
    }


}

我得到如下日志猫：

也许您正在尝试播放不受支持的格式。你知道什么失败了吗？: new, setDataSource, prepare, start ... 而且 IOException 告诉你输入文件有问题，例如 FileNotFoundException 或 EOFException （尝试打印出更具体的异常，如建议here）
