Ao realizar o download do botão FloatingActionButton ele tecnicamente roda tudo, porém não consigo arrastar o botão para o projeto de acordo com a Aula que estou seguindo passo a passo!!!
This operation requires the library com.android.support:design:+.
Problem: Inconsistencies in the existing project dependencies found. Version incompatibility between:
- com.android.support:appcompat-v7:28.0.0 and:
- com.android.support:appcompat-v7:28.0.0
With the dependency:
- com.android.support:support-annotations:26.1.0 versus:
- com.android.support:support-annotations:28.0.0
The project may not compile after adding this library. Would you like to add it anyway?
