TIL how to get my first Android App running on my phone

So for background, I'm an IT Consultant, and mostly work in the development space, but one area I've never touched before has been mobile app development. So today, I spent the day getting a new GitHub repo sorted out, put together a pretty simple Actions workflow with SonarQube integration and basic test gates.. on that note, got a new VPS up and running and deployed SonarQube there. Then finally just got my first Gradle project running on Android Studio, and after dealing with a corrupted keystore (fixed by just nuking the keystore, cleaning the project and rebuilding), I finally got technically my first Android app running on my S25 😄😄
