No, WebViewGold for Android does not support Data URLs.
Data URLs are URLs that are prefixed with the data: scheme (for example, “data:;base64”) and allow content creators to embed small files inline in documents.
They are not natively supported by Android WebView browsers. WebViewGold uses an Android WebView browser to host the website in the app format, therefore they are not supported.
Unfortunately, this is a downside to WebView browsers. They don’t support all the same features that desktop browsers support.
Currently, Data URLs loaded into the app will just be overridden, since there are no capabilities to read them. This means nothing will happen and the app won’t crash.
