I solved the problem with publishing the game on google play.
1. You need to have the latest version of stencyl
2. In Game settings in Stencyl you must make an Android Certificate.
Stencyl will generate a file *. keystore
This file *. keystore must be encoded to the appropriate format using KeyStore Explorer program ( free software-There are tutorials available on how to do this )
You need to ask for a reset of app signing on google play, and upload the generated file with KeyStore Explorer.
Once your encoding file has been approved by Google Play, you can upload your game files in aab format.
Other games can also be signed with the same key
This solution allowed me to skip the use of Android Studio in the process
Unfortunately, there is no such information in stencylpedia
I hope I can help someone by sharing this information
