Another reason that messages such as these can come up in Android Studio when building and launching can be the cause of application tags in your libraries.

If you have several Android Library projects that you imported as modules. Go into those projects and remove the ... tags and everything between them. These can cause issues in the build process along with the support library issues already mentioned.
