我已经使用媒体播放器之前，我从未有过这个问题。每当我尝试使用MediaPlayer.create（），该方法给我空了，我不能发挥出自己的声音。这有什么，我很想念？

I have used the mediaplayer before, and I have never had this problem. Whenever I try to use MediaPlayer.create(), the method gives me null, and I can't play my sounds. Is there anything that I am missing?

public class Game extends Activity
{
    private MediaPlayer mp = null;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.game);

        mp = MediaPlayer.create(getBaseContext(), R.raw.sound);
    }
}

我sound.mp3在我的原始文件夹中，这是我摆在那里draging我的声音文件夹中的日食。请帮助，因为我之前打了声，这实在是烦我：（

my sound.mp3 is in my raw folder, which I placed in there by draging my sound to the folder in eclipse. Please help, since I have played sound before, this is really bugging me :(

推荐答案

的创建（），如果它以某种方式失败 API返回null。

The create() API returns null if it somehow failed.

的原因，在这种情况下，是由于损坏的mp3文件。

The reason in this case is due to a corrupt mp3 file.
