Solution 1:

Remove this dependency from your build:

compile'com.firebaseui:firebase-ui-database:2.0.0'

This is a very old version of Firebase-UI. You should be using the instructions here instead. Also consider updating your version of the Firebase SDKs, and make sure that there is a match between the version of Firebase-UI and the SDKs as shown in the table in the docs I referenced.
