  1. A couple of posters have mentioned getting BabylonJS projects on to Android. This is my take on this, the whole code developed using Basic4Android (sometimes called B4A). It is a fairly mature platform - I've been using it for about 7 years now. For Basic4Android you can develop an App which creates a WebView which then loads the HTML which then loads the Javascript, which access BabylonJS. You can, obviously, send variables to the HTML (pretty standard) and/or pass variables back to the Android App - I'll leave the code in there to enable you to do that as well as I think it's quite useful to do and to see how it's been done. You WILL need some libraries, which are only available to Licensed Users (but at no extra cost). They are : WebViewExtras2 (ver 2.20) WebViewSettings (ver 1.31) JavaObject (2.05) Reflection (2.40) Phone (2.50) IME (1.10) I use other libraries in addition to these - but they are to do with Firebase / Admob and a few graphical elements. StringUtils and RuntimePermissions. B4A demo code in full. This should work, but I'm happy to help out or you can always post questions on the B4A Forum ( https://www.b4x.com/android/forum/ ). I'm using the latest release version of B4A which is 8.50 but you shouldn't necessarily need that version - probably only around 6.80 or later. #Region Project Attributes #FullScreen: True #IncludeTitle: False #ApplicationLabel: Demo #VersionCode: 1 #VersionName: 'SupportedOrientations possible values: unspecified, landscape or portrait. #SupportedOrientations: landscape #CanInstallToExternalStorage: False #End Region #Region Activity Attributes #FullScreen: True #IncludeTitle: False #End Region Sub Process_Globals 'These global variables will be declared once when the application starts.

"& variable) End Sub Of course you will need to make sure that the HTML and Javascript reside in the correct (sub)directories. Just passing a single variable to the Javascript, but could pass more.

As I said I'm happy to help out or post questions on the B4A forum.
