Android

Hyperion runs on Android phones and tablets. Support works, but isn't stable yet.

What you'll need

The Android NDK. We test with NDK 29. Point ANDROID_NDK_HOME at it.
Ninja, on your PATH or installed with Visual Studio or the Android SDK.
The Android SDK and Java 17, for Gradle. Android Studio installs both.
A regular Windows Release build of the engine (build.bat Release). Packaging uses its shader and cooking tools.

We build for 64-bit ARM (arm64-v8a), and you'll need Android 9 (API 28) or newer.

Build it

Build the engine for Android and package it with your project's content:
```
Tools\Scripts\PackageBuildAndroid.bat --cook --project MyGame
```
This makes its own shipping build for Android, so you don't need to run build.bat Android first. --project is the project's folder name under Projects/. Without --cook, only engine content is included. --skip-precompile skips precompiling shaders.

The package lands in PackagedBuilds/Android/Build_<date>_<time>/.
Build and install the APK with Gradle, from Source/PlatformSpecific/Android/:
```
gradlew.bat installDebug
```
Gradle picks up the last package automatically. You can also open that folder in Android Studio and run it from there.

To build only the engine libraries, without packaging: build.bat Android Release. They end up in Binaries/Android/Release/.

Settings

Android uses Config/EngineConfig.Android.json instead of the regular config with platform-specific overrides for targeting lower end devices than the typical desktop experience.

The Mobile device tier rule applies on top of it.
