Answer 1

If you have Android Studio 2.3.3 and Android Studio 3.0.0 installed, then switching between the two programs for development will cause this error. This is because there exist situations where classes supported in one program is not supported by the other and vice versa. It is important to maintain consistency in which version of Android Studio is being used to develop a project.
