Managing app versioning in Android Studio - simplifying versionCode, versionName, and versionNameSuffix
Versioning is an important aspect of any mobile app development process. In Android, this is handled through versionCode and versionName, which allow you to define the current state of your app for users and the Play Store. But where exactly should these be managed, and how can you ensure they propagate correctly across your project? This article covers the essentials of managing app versioning in Android Studio, using the build.gradle file.
Android icon not changing
If the Android app icon is not changing from the default icon (in my situation this was the Capacitor icon), here are some steps to troubleshoot and resolve the issue:
Check the Icon Files
