Hi everyone. I want to make a license key for my app/
For example, I want to make an app like "Poweramp full version unlocker". When open this app, it will check if Poweramp trial version has installed. If yes, everything OK. If not, it will show a button to "Get poweramp trial version"
I want to bind this command to my app, if user want to launch my app, they have to install another app or go to a link I requested
Please instruct me, step by step, and detailed
Thanks for reading
