How do I upload my APK to Google Play Developers Console? I need to do that so I can get the license key.
When you log in to the developer console there is a link at the bottom for Help Center which will answer this question.
But what license key do you mean?
This part of config.lua:
license = { google = { -- The "key" value is obtained from Google key = "Your key here",
I have a friend that might be able to help you… ill get him to look at this forum post.
Ok, so I will upload some pictures. Once you are on the developer console. Press the blue “Add New Application” button on the top right of the screen.

After that, you should basically know what to do from there…
Here is the picture of what it would look like next:

If you are having trouble finding the page, here is the link to that console:
https://play.google.com/apps/publish/
ALSO, by “Key” do you mean the Keystore? If you need help with that just say so, and I will get back on.
Told you he’d help! :D 
Haha yup.
