The Oculus Mobile SDK includes libraries, tools, and resources for native C/C++ development of apps for Oculus devices that use Android, which are Oculus Quest and Oculus Go. If you primarily use Unity or Unreal Engine for Android development, it is not necessary to download the Mobile SDK in most cases . For more information on Unity and Unreal Engine Android development, see Mobile Development with Unity and Unreal.
