I have been struggling to get this to work. I am choosing Espresso as a framework to test because I see there is support in Xamarin Test Cloud, Firebase and Amazon Device Farm which makes it easier to port the tests.
Also, I like the fact that you can just record a test with Android Studio. The problem is that my clicks are not being catched. Only the ones that I made on the Back button.
It seems all the Touchable views in RN are being ignored. I understand RN creates Views in a different way, and also there is no resourceId.
i had the same error, for some reason Espresso does not support full Test Recorder clicks, you can do a few with the recorder but you will need to do some manually as this video says

as the documentation says
espresso-core - Contains core and basic View matchers, actions, and assertions. See Basics and Recipes.
