Bad state: The same type cannot be registered twice

[pishguy]

when i try to use Fmvvm like fragment in android i get this error:

Bad state: The same type cannot be registered twice

That error happens if you try to register two different classes in the component resolver to the same type which isn't allowed. The components are resolved by type so if you were allowed to register two components to the same type, it wouldn't know which one to return.
