This suggests you're missing the package dependency that provides osmdroid; is org.osmdroid:osmdroid-android:6.1.0 specified in the dependencies in build_gradle_dependencies?

Along with the text of the error message above, this is documented in the MapView docs.

[mjoy99]

I completely missed that part in the documentation. I updated the project.toml and was able to get it to work. Although, I couldn't get it to add the dependency through any of the below. Not sure how you get gradle to see it has updated dependency requirements.
I tried:
briefcase update android -r
briefcase build android -u
briefcase create android
and a few others, but until I deleted the android build and did the create again, I couldn't get the depency to add in.
