I have an old app I have to support and the keystore for it has been lost. I need to create a new keystore so I can sign my APK and deploy it as an essentially brand new app.
As it is an old App I have an old version of Gradle. I'm currently using Android Gradle Plugin Version 2.1.2 and Gradle Version 2.10 running on Android Studio 3.5.
If I try and use Build->Generate Signed Bundle or APK from Android Studio I can receive an error saying that my Gradle Plugin Version should be updated to 3.2.
Upgrading is causing some issues and also introduces too many changes to my app that I will need to test.
All I need to do is sign the app for delivery. I know that it will be a different app to the previous version and I can solve that issue.
My question is how can I sign my App and add it in such a way Android Studio can do a proper signed release build?
