I want to sign the apk of my application that has been ready for 1 month, but I can not create this 'keystore' in any way. I've tried it online in Android Studio (zzz) and am trying it at the command prompt for 2 weeks. I have tried to follow some tutorials for this but they ask to install java and then a JDK and open the prompt as administrator and it still does not work in any way.
If someone can help me, I appreciate it.
