Question

我正在尝试将Unity播放器设置为壁纸引擎

代码：

private class MyWallpaperEngine extends Engine{
    UnityPlayer mUnityPlayer;
    @Override
    public void onCreate(SurfaceHolder surfaceHolder) {

        mUnityPlayer = new UnityPlayer(MyWallpaperService.this);
        int glesMode = mUnityPlayer.getSettings().getInt("gles_mode", 1);
        boolean trueColor8888 = false;
        mUnityPlayer.init(glesMode, trueColor8888); //line 33
        super.onCreate(surfaceHolder);
    }.....

我遇到错误：

任何想法都有什么问题？我应该使用其他背景（如何）？在此先感谢
