0x00000000的致命信号11（Sigsegv）（代码=1）？

为什么会出现此问题？

public static String path;
private VideoView mVideoView;


mVideoView = (VideoView) findViewById(R.id.surface_view);
mVideoView.setVideoPath(path);
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();

//...

    private int mLayout = VideoView.VIDEO_LAYOUT_ZOOM;

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        if (mVideoView != null)
            mVideoView.setVideoLayout(mLayout, 0);
        super.onConfigurationChanged(newConfig);
    }
