Can I use Google Play App Signing for my Cocoon app?
I actually don't even know what it is, i'm trying to upload my game to Play Store and i need to make sure that my game is safe.
Also, am i have to do the zipalign thing? What does it do?
Yes you can. Just uncheck your key at your project settings, so that you get an unsigned apk file.Upload it then to Google App Signer.
