Question

我在我的应用程序中使用以下代码来播放声音。但我无法发挥它。问题是什么？

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");
    }


}

我得到了log cat，如下所示：

05-09 05:24:22.272: VERBOSE/PlayerDriver(95): Completed command PLAYER_INIT status=PVMFFailure
05-09 05:24:22.272: ERROR/PlayerDriver(95): Command PLAYER_INIT completed with an error or info PVMFFailure

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（尝试按照建议打印出更具体的异常here）
