Creating the google account is easy, (cost $20 or something).
As for cocoon.js, it's cocoon.io now, and after they got the bugs out, it's better then ever!
I managed to get my game on the play store finally! (Drift Cross).
I've decided on my preferred way of getting games outa C2 and onto the Play Store:
step 1) uninstall intel xdk and never look back!
step 2) use cocoon.io which now handles signing! just upload unsigned, config settings, auto sign and compile!
step 3) upload signed apk to google play!
.. although I still haven't made my free version with ads yet.
I've seen a few posts about getting ads working and there's a few things you have to enable in cocoon.io
By the way, the cocoon forums are great, they've put a tonne of effort into accommodating us C2 users.
I really don't want to discourage anyone from having a go.
It's been a very painful process, but if I could go back in time I would do it all again (and wait for cocoon.io to come out first).
The thing that really threw me was that I was trying to publish during a period where things were in transition and buggy. (plus frustration and lack of sleep)
That and the Intel XDK and Java DK suck... did a year ago, still do today. I duno what kind of brain you have to be able to understand those kits, but I'm sure it's nothing short of a bachelor degree combined with caffeine induced mental distortion. Sorry but they're just bad.
If you came to C2 because of it's low coding, object oriented system and don't know how to code like 1337 god... stick with cocoon.io
Regarding Monaca, I havn't used it but I noticed you get 3 apps with the free account, combine that with Cocoon's 2 and you can work with 5 apps at once, maybe you can cycle out apps that arn't getting worked on and free up a spot for a new one.
To think it was meant to be a quick, "just get something really simple published" and move on... 1 year later.
At least I know what I'm in for if I do it again.
