# Cross-platform Management

{% hint style="warning" %}

## This package uses a combination of build profiles, wrapping dependency packages in scripting defines, and custom AndroidManifests and Gradle templates to support multiple XR SDKs in the same project. This is a recent capability as of Unity 6.

We highly recommend starting with an [Example Project](https://docs.meshmap.com/unity-sdk/overview/example-projects) and carefully following the instructions for each device ([Magic Leap 2](https://docs.meshmap.com/unity-sdk/xr/cross-platform-management/magic-leap-2), [Meta Quest 3](https://docs.meshmap.com/unity-sdk/xr/cross-platform-management/meta-quest-3), and [XREAL Air 2 Ultra](https://docs.meshmap.com/unity-sdk/xr/cross-platform-management/xreal-air-2-ultra)) to ensure your app works properly.
{% endhint %}

## Getting Started

Supporting multiple XR SDKs in the same Unity project requires handling many settings and permissions. The best way to get started is to use one of our [Example Projects](https://docs.meshmap.com/unity-sdk/overview/example-projects), which have these settings preconfigured.
