Labels and lines not shown in android webview element

[joaofpc-min]

VirtualSky is the perfect thing for my Android App that guides me, by using phone built in orientation sensors, to a particular cellestial body in the sky (that looks idicotic but will help myself that knows nothing about astronomy). However, labels and constellation lines don't get shown on my android app webview. Is there some sort of step I'm missing?
Thanks in advance.

Problem was on webview settings side:

Just set:
myWebView.settings.allowUniversalAccessFromFileURLs = true

and everything works fine. Thanks a lot.
