who said intelxdk will close their doors? from what it looks on their official website and product development their here to stay. i couldn't find anything related to intel xdk being drop'd anytime soon. am i out of loop? :O
by retiring is this what you meant? (XDK will focus on IoT Apps)
P.S i think you could get the same cordova compiler from GitHub if im not mistaken i still have a small compiler in my pc around here pulled from GitHub, it makes all html5 games into APK ready to be signed with android SDK which once you got the apk is easy to sign it. and it doesn't give u a arm or x86 but 1 apk that works on both, like how cordova was doing when intelxdk was a new choice for C2. (not sure if you remember that).
Edited: so my choice would be this one here ht5ml to native apk if intelxdk would drop the android support compiler solution they have.
i hope my input help if not, sorry i have no clue!
P.P.S and the good part on my solution is that you can improve it also as you want if you know JS - plus are benefits and i kinda cant see a downside to it... once you set a certification signature for android SDK no limit on how many APK u can export, plus alteration of the source code without any limitations, of course there is that where nobody will probably pick it up and support it since the original maker, seems to have drop'd it for some years now. but i think would still be a good tool to have until something better pop's up. (yes i tested it, a few times needed a apk and intelxdk was offline for update or something. and was working perfect, however i only used the unsigned apk since i only needed to test things on mobile and not publish).
to use it just follow the official quick instruction
Now run go.bat. An application called app.signed.aligned.apk will be generated and you can install and run it on your phone. The APK is quite big because it includes a cutting edge version of the chromium browser, with asm js, WebGL and WebAudio.
