Welcome to AF and good luck with development for your app

I wish I could help you but that is simply beyond my comprehension I'll work on your semi tractor/trailer but as far as app development?-- not this guy

 

I know you use Android Studio, and I think you code in either Java or Kotlin. Yeh, I'm not a dev either, I teach English and not programming languages.

 

There's some useful information here about programmatically checking the battery level
