片段中的媒体播放器错误

Question

我试图创建一个小型媒体播放器。因此我写了这段代码来播放位于assets文件夹中的.aac文件：

public class FragmentDominik extends Fragment {
    Button button;
    View view;
    //MainActivity mA = new MainActivity();
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.dominik,container, false);
        button = (Button) view.findViewById(R.id.dominikButton1);
        Log.v("Syx","In Activity");
        button.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                Log.v("Syx","Clicked");
                try {
                    MediaPlayer player = new MediaPlayer();
                    AssetFileDescriptor descriptor = view.getContext().getAssets().openFd("dome__heeey.aac");
                   /* if (mA.mP.isPlaying())  {
                        mA.mP.reset();
                    }*/
                    Log.v("Syx","Playing");
                    player.setDataSource(descriptor.getFileDescriptor());
                    Log.v("Syx", "Playing 2");
                    player.prepare();
                    Log.v("Syx", "Playing 3");
                    player.start();
                    Log.v("Syx", "Playing 4");
                } catch (IOException e) {
                }
            }
        });
        return view;
    }
}

但由于某些原因，当我尝试播放音乐时，它会给我一个错误，所以在Log＆＃34;播放2＆＃34;之后出现错误，所以错误与player.prepare有关（）;.我不知道是什么导致了这个错误，所以任何帮助表示赞赏:) 编辑：Stacktrace
