The goal is to familiarise developers with the SDK configuration for building applications on Leonardo. The next guide covers how to interact with controllers and hands. Leonardo XR runs Android 12 and follows a development workflow familiar to anyone who has previously built Android applications. Required Software Before starting, make sure the following software and packages are installed at the specified versions: Software / Package Version Unity Hub Latest available Unity Editor 6000.0.58f2 LeonardoXR SDK 1.0.2 Snapdragon Spaces SDK 1.0.4 OpenXR Plugin 1.15.1 AR Foundation 6.2.1 XR Interaction Toolkit 3.3.0 XR Hands 1.7.2 UniTask 2.5.10 VS Code, Visual Studio or similar IDE — NOTE Unlike the base Snapdragon Spaces guide (which recommends v1.10.0 for Unity 2022), Unity 6 with LeonardoXR uses OpenXR 1.15.1. Do not modify this version manually — the Package Manager handles it through the SDK dependencies. Create a New Project Open Unity Hub and click New Project. Select the Universal 3D template. Name the project (e.g. LeonardoXR_Test) and choose a destination folder. Click Create Project. After creation, Unity opens the project with a sample scene in the Hierarchy panel. Switch Platform to Android From the main menu select File > Build Profiles. In the Build Profiles window select Android from the Platform list. Click Switch Platform and wait for the process to complete. Close the Build Profiles window. Install Snapdragon Spaces SDK IMPORTANT Snapdragon Spaces SDK must be installed before the LeonardoXR SDK. The LeonardoXR runtime depends on it and will not compile without it. Download Snapdragon Spaces SDK v1.0.4 from the Qualcomm developer portal (a developer account is required): https://spaces.qualcomm.com/developer/vr-mr-sdk/#downloads Open the Package Manager (Window > Package Manager). Click + and select Add package from tarball… Browse to the downloaded .tgz file and click Open. Installation will start automatically. During installation, two prompts may appear: “Enable the new input system?” → click Yes. “XR Interaction Layer Mask Update Required” → for a new project, click I Made a Backup, Go Ahead! NOTE The editor will restart after installation — this is expected behaviour, not a crash. For version control, copy the .tgz into the project’s Packages/ folder before adding it; the manifest will then use a relative path, which is better for source control. Unity 6.3+ — Known Spaces SDK issue: After installation you may see the following compile error: BaseRuntimeFeature.InterceptEnvironmentBlendMode.cs(15,10): error CS0592: Attribute 'SerializeField' is not valid on this declaration type. To fix it, double-click the error in the Console to open the file, then remove the [SerializeField] attribute on line 15. This is a bug in Snapdragon Spaces 1.0.4 that only surfaces on Unity 6.3 and above. Install LeonardoXR SDK Download LeonardoXR SDK v1.0.2 from the Youbiquo Developer area. Open the Package Manager (Window > Package Manager). Click + and select Add package from tarball… Browse to the LeonardoXR SDK .tgz file and click Open. The SDK will be installed together with its dependencies: OpenXR Plugin 1.15.1, AR Foundation 6.2.1, XR Interaction Toolkit 3.3.0, and XR Hands 1.7.2 — no manual installation of these packages is required. LeonardoXR SDK Manager After the LeonardoXR SDK is installed, a LeonardoXR SDK Manager window opens automatically. If it does not appear, open it from LeonardoXR > SDK Manager in the menu bar. The window has two tabs: Setup tab — displays the status of the two packages that cannot be resolved automatically: Package Status Action Snapdragon Spaces SDK 1.0.4 ✓ / ✗ Browse… — opens a file picker to select the .tgz and installs it via Package Manager UniTask 2.5.10 ✓ / ✗ Install — installs UniTask directly from the official Cysharp Git repository Once both packages show ✓, the setup is complete. Use the ↺ Refresh button at any time to re-check the current state. About tab — displays version information for the SDK, device, and Unity Editor. Configure XR Plugin Management and OpenXR Open Project Settings Go to Edit > Project Settings and select XR Plug-in Management in the left sidebar. Enable OpenXR and Snapdragon Spaces Click the Android tab (top right of the window). Under Plug-in Providers, ensure both are checked: OpenXR and Snapdragon Spaces feature group. Configure OpenXR Features Click OpenXR in the left sidebar. In the Snapdragon Spaces feature list, enable only Base Runtime and disable all others. Advanced features (Hit Testing, Plane Detection, etc.) can be enabled later as needed. NOTE For Hand Tracking to work correctly on LeonardoXR, the Hand Tracking Subsystem option must be enabled in the All Features section of OpenXR. Add LeonardoXR Feature Group Return to XR Plug-in Management > Android. In the Plug-in Providers list, also check LeonardoXR feature group. Run Project Validation In the Project Settings sidebar click Project Validation. The window shows a list of configuration errors to fix. Click Fix All to resolve them automatically. NOTE Some fixes may require an editor restart. Re-run validation after restarting to confirm all errors are resolved. Import Samples Before creating your own scenes it is useful to import the samples included in each package. For each package: open Window > Package Manager, select In Project, select the package, expand the Samples section and click Import. Package Samples XR Hands Gestures, Hand Visualizer XR Interaction Toolkit Starter Assets, Hand Interaction Demo Snapdragon Spaces Core Samples LeonardoXR Core Samples, Documentation After importing all samples, add scenes to the build via Window > XR > Snapdragon Spaces > Add Scenes to Build Settings. Configure URP Graphics and Quality Settings Open Edit > Project Settings > Graphics. Under Default Render Pipeline, click the circle and select Mobile_RPAsset. Go to Project Settings > Quality. In the Levels section, ensure Mobile has a green checkbox in the Android column. If not, click the Default triangle under Android
