This HowTo was tested with Java runtime version 11, Android SDK platform 30, gradle plugin version 7.3.1 and Android native API level 30

To build AutomatedTesting for Android

1. Set your JAVA_HOME to where Android Studio has it installed

set JAVA_HOME="C:\Program Files\Android\Android Studio\jbr"

2. Generate the Android Studio project with generate_android_project.py

cd o3de
 .\python\python.cmd cmake\Tools\Platform\Android\generate_android_project.py --engine-root f:\git\o3de-dev-worktree --build-dir build\android --third-party-path f:/git/3rdparty --project-path AutomatedTesting --android-sdk-path c:\Users\username\AppData\Local\android\Sdk  --gradle-plugin-version 7.3.1 --android-sdk-platform 30 --android-native-api-level 30 --enable-unity-build --include-apk-assets --asset-mode LOOSE

3. Open Android Studio and load the generated project in build/android
4. Wait for Gradle to do any processing, then connect your device and press the Run/Play button

The generated .apk should be in the build\android\app\build\intermediates\apk\profile folder. If you try to run the deploy_android.py script it will look for the .apk in the build\android\app\build\outputs\apk\profile folder and you may have to manually copy it there.
