将SVG（可缩放矢量图形）加载到AndEngine中

Question

我正在尝试将一些SVG加载到我的游戏中，但我正在使用truoble。我试过从论坛上阅读Android烹饪书，文档和答案，但我找不到解决方案。我现在处于一个可以实际加载图像和游戏构建的状态，但现在我无法显示它们。见如下：

在.svg图片中加载：

BuildableBitmapTextureAtlas bitmapTextureAtlas = new BuildableBitmapTextureAtlas(
            engine.getTextureManager(), 1024, 1024, TextureOptions.BILINEAR); //setting up texture atlas

    try {
        this.mBuildableBitmapTextureAtlas
                .build(new BlackPawnTextureAtlasBuilder<IBitmapTextureAtlasSource, BitmapTextureAtlas>(
                        0, 0, 1));

    } catch (final TextureAtlasBuilderException e) {
        Debug.e(e);
    }



    SVGBitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/game/");

    mLowResTextureRegion = SVGBitmapTextureAtlasTextureRegionFactory
            .createFromAsset(bitmapTextureAtlas, activity,
                    "spinningarrow.svg", 32, 32);
    mMedResTextureRegion = SVGBitmapTextureAtlasTextureRegionFactory
            .createFromAsset(bitmapTextureAtlas, activity, "spinningarrow.svg",
                    128, 128);

    // Create a high-res (256x256) texture region of svg_image.svg
    mHiResTextureRegion = SVGBitmapTextureAtlasTextureRegionFactory
            .createFromAsset(bitmapTextureAtlas, activity, "spinningarrow.svg",
                    256, 256);

    bitmapTextureAtlas.load();

实际上将它附加到场景中：

float currentSpritePosition = (WIDTH / ((SPRITE_SIZE) * SPRITE_COUNT)) + SPRITE_SIZE * 0.5f;

            Sprite lowResSprite = new Sprite(currentSpritePosition, HEIGHT / 2, SPRITE_SIZE, SPRITE_SIZE, rM.mLowResTextureRegion, rM.engine.getVertexBufferObjectManager());
            attachChild(lowResSprite);

            currentSpritePosition += SPRITE_SIZE;
            // Create & attach the med-res sprite to the scene (mid)
            Sprite medResSprite = new Sprite(currentSpritePosition, HEIGHT / 2, SPRITE_SIZE, SPRITE_SIZE, rM.mMedResTextureRegion, rM.engine.getVertexBufferObjectManager());
            attachChild(medResSprite);

            currentSpritePosition += SPRITE_SIZE;
            // Create & attach the high-res sprite to the scene (right side)
            Sprite hiResSprite = new Sprite(currentSpritePosition, HEIGHT / 2, SPRITE_SIZE, SPRITE_SIZE, rM.mHiResTextureRegion, rM.engine.getVertexBufferObjectManager());
            attachChild(hiResSprite);

这构建，但我看不到图像;即使我硬编码它的坐标。
