> You can do signing through Intel XDK. You create your keystore and such with the menu in the program, and select which keystore you want to sign it with in the apps options before publishing it. Literally just click on the warning messages inside of intel xdk
Do you have a tutorial for this?
I'll be frankly honest with you. Following the error messages and clicking the links they provide inside of Intel XDK, or a quick google search, would have solved this issue for you. Making a game is not easy, even with a program that does the code for you. If you cannot follow hints or do a quick search on your own to find the answer, you cannot hope to make a game.
With that being said, I understand this comes easier to some then others, so I took the time to make you a tutorial. Next time try and figure it out on your own as that is the best way to learn and to improve.
