1. Setup IntelliJ with Android (plugin, SDKs etc).
2. Get the Android 13 image for the emulator (important: Android 13), then run the emulator. *Skip this step if you use a physical device.*
3. Make sure you can build the APK.  
    a. `mvn clean verify -P android-debug` using the working directory forge-gui-android/
4. Use `android-debug` profile for creating the debug version from below in the forge-gui-android/pom.xml
5. Use this maven command: `mvn android:deploy-apk android:run`
6. Look at the emulator (or device), it should say "Waiting for debugger to connect".
7. CRTL+SHIFT+A in IntelliJ and type in `attach android` and click on "Attach Debugger to Android Process".
8. Tick "Show all processes" and you should be able to pick `forge.app` from the list and click "Okay".
9. Ready to debug
