My Android project compiles, deploys to the emulator, but throws an exception why trying to call a static field from the Resource file. When I add a break point on the line making a call to Resource.Layout.Login (Login is a axml file) it says "Resource.Layout.Login = Unknown identifier: Resource". This originally was working. I don't know what caused this to start happening. I have been able to make calls to Resource.Layout.Login in previous tests. What could cause this? How do I fix?
