I created a new key;
created a build with that key;
uploaded to google store;
completed process like any other app;
all went fine, it’s already on store live.
so i guess this new feature for corona users is same as before. i didnt had to upload any key. but i could not use the same key as before. for people that already create new keys for every app this is nothing new to them.
I downloaded a certificate provided on the new section “Google Play App Signing” and installed on my windows machine (but don’t know if this done anything to the key I created after).
The app I used this new method can be found in google play or apple store with the name “Tea Timer Gorreana”. It’s just a simple app for timing the tea, so you can have a perfect tea every time, using the app client tea (the largest tea maker company in Europe). I used material design guide lines from google website. all functions were done by me. already using them on another project.
