CDogs1964 sounds like you've found a unicorn combination. If it's working for you just go with it till it doesn't. However I will say it's still worth looking into at some point.. not just strictly from a plugin perspective but nice things like MUCH easier management of plugins, though with your luck the difference may not be appreciated.. a single graphic you provide gets turned into all the required icon sizes needed. if you've ever had to go into photoshop to do 72x72.. 96x96.. etc etc.. you know what I'm talking about. Also for people who favor making games for android, Cocoon IO makes incredibly small android games.. Crosswalk introduces 19mb + your game. While Crosswalk I've seen be as little as 2mb + your game.
what version of XDK are you using? are you building 4.1.2 or 5.1.1? what versions of each of the plugins are you using as well? oh and what version of Construct 2? I don't really expect you to answer all that stuff, but what i've experienced
I've used all of those plugins except facebook and have had them work at one point or another and then have them not work... except admob.. that one has been pretty damn steady through it all.
the thing that has tripped me up and others I have spoke with is one day a plugin works then you update something.. or you don't update something and it breaks. heh. So it's just been, in my experience a moving target and sure a solution usually presents itself but if I'm working on a project for someone else.. up time is super important to stay on schedule.. not as much time to wait on someone to update something.
