    return getCssWebResourceResponseFromAsset();
    } else {
    return super.shouldInterceptRequest(view, url);
    }
    }


    private WebResourceResponse getUtf8EncodedCssWebResourceResponse(InputStream data) {
    return new WebResourceResponse("text/css", "UTF-8", data);
    }
    private WebResourceResponse getCssWebResourceResponseFromAsset() {
    try {
    return getUtf8EncodedCssWebResourceResponse(getAssets().open("css/"));
   } catch (IOException e) {
    return null;
    }
