Overall I need to say that once you develop your app and finally obtain your APK file (installation file format), use the Google play console to deploy your app in the google play store is pretty straight forward. Below a list of the main steps to follow:
- Access to the Google play console (you need a Google account)
- Accept the distribution agreement and pay the 25$ fee
- Finally you can follow the process to add a new app.
I found it very intuitive and clear. Really happy about the entire process. Well done Google!
