I do not currently have the mobile export, but was wondering if this would work on mobile as well.

Unfortunately this would not, as the Chromium Embedded Framework  DLL that it uses is Windows only.  While CEF could also be built for Mac and Linux (I don't have the experience to do that, but could assist anyone who does), unfortunately it is not available for Android.

I have seen some other extensions that provide a web view for Android though.

I could be probably be ported to Android usind the NDK which translate C/C++ to Android app and is how Game Maker Studio export to Android.
