I Am Getting Error When Trying To Add Phone Authentication In My Android App Project

I am trying to add phone no. authentication in my new video app (I already have Facebook and Google authentication in my app) and they are working well. I need to save and parse us

Solution 1:

You have not given any id to the top_view. You are using top_view before starting MainMenuActivity in the LoginActivity class. This might me one of the reason for the app to stop.
