I've been trying to connect my firebase with android but I get an error in
implementation 'com.android.support:appcompat-v7:28.0.0'
I do not know how to solve it if you could help me
I do not know what the problem is, I have already implemented the firebase implementation and I can not solve the error
implementation 'com.google.firebase: firebase-auth: 16.0.1: 15.0.0' implementation 'com.google.firebase: firebase-core: 16.0.1'
In the dependency you are trying to add in auth, there are 2 versions, this is automatically set from android studio when you connect Firebase, in this part
implementation com.google.firebase:firebase-auth:16.0.1:15.0.0 <--- dos versiones
you should leave only one, you can replace it with the latest version
implementation com.google.firebase:firebase-auth:16.1.0
You can check the latest versions of each component here (I pass the link in English because the documentation in Spanish is outdated in the version table)
