Hi @Burnbob, welcome to the Speckle forums.
This topic has come up a few times (see Unity Android build)
Unfortunately, our Unity Connector doesn’t fully support Android platforms, at least not out of the box.
If you’re willing to jump through some hoops, we have seen some success receiving Speckle objects on android.
Please see this github ticket which explains the limitations.
The tldr is , You won’t be able to use the normal SpeckleReceiver and SpeckleSender components.
In the past, we’ve used/the ManualReceive component to showcase receiving on Android. This allows you to manually specify an authtoken (aka personal access token).
This does work on android, but will likely require you to build out a your own components for authentication, receiving, and UI.
I can provide some more direction if you end up going down this route, but a lot will depend on the type of app you’re wanting to build.
