Visual Studio 2022 Community - Make sure to select "Desktop development with C++" support in the installer. Make sure to update to the latest version if already installed.
Vulkan SDK - Make sure to select Latest SDK.
- A convenience script to install the latest SDK is provided in .ci\windows\install-vulkan-sdk.ps1.

Cloning Eden with Git

git clone --recursive https://git.eden-emu.dev/eden-emu/eden.git

Eden by default will be cloned into:

C:\Users\<user-name>\eden on Windows
~/eden on Linux and macOS

Building

Start Android Studio, on the startup dialog select Open.
Navigate to the eden/src/android directory and click on OK.
In Build > Select Build Variant, select release or relWithDebInfo as the "Active build variant".
Build the project with Build > Make Project or run it on an Android device with Run > Run 'app'.

Building with Terminal

Download the SDK and NDK from Android Studio.
Navigate to SDK and NDK paths.
Then set ANDROID_SDK_ROOT and ANDROID_NDK_ROOT in terminal via export ANDROID_SDK_ROOT=path/to/sdk export ANDROID_NDK_ROOT=path/to/ndk.
Navigate to eden/src/android.
Then Build with ./gradlew assembleRelWithDebInfo.
To build the optimised build use ./gradlew assembleGenshinSpoofRelWithDebInfo.
You can pass extra variables to cmake via -PYUZU_ANDROID_ARGS="-D..."

Remember to have a Java SDK installed if not already, on Debian and similar this is done with sudo apt install openjdk-17-jdk.

Script

A convenience script for building is provided in .ci/android/build.sh. On Windows, this must be run in Git Bash or MSYS2. This script provides the following options:

Usage: build.sh [-c|--chromeos] [-t|--target FLAVOR] [-b|--build-type BUILD_TYPE]
                [-h|--help] [-r|--release] [extra options]

Build script for Android.
Associated variables can be set outside the script,
and will apply both to this script and the packaging script.
bool values are "true" or "false"

Options:
    -c, --chromeos          Build for ChromeOS (x86_64) (variable: CHROMEOS, bool)
                            Default: false
    -r, --release           Enable update checker. If set, sets the DEVEL bool variable to false.
                            By default, DEVEL is true.
    -t, --target <FLAVOR>   Build flavor (variable: TARGET)
                            Valid values are: legacy, optimized, standard
                            Default: standard
    -b, --build-type <TYPE> Build type (variable: TYPE)
                            Valid values are: Release, RelWithDebInfo, Debug
                            Default: Debug

Extra arguments are passed to CMake (e.g. -DCMAKE_OPTION_NAME=VALUE)
Set the CCACHE variable to "true" to enable build caching.
The APK and AAB will be output into "artifacts".

Examples:

Build legacy release with update checker for ChromeOS:
- .ci/android/build.sh -c -r -t legacy
Build standard release with debug info without update checker for phones:
- .ci/android/build.sh -b RelWithDebInfo
Build optimized release with update checker:
- .ci/android/build.sh -r -t optimized
