问题
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 user data in the server and in local as well.
I do not know much about phone number authentication, please help me to fix the issue in phone no. authentication.
As I already said Facebook and google authentication working perfectly and user data from these is also saving in local and server as well.
Please make phone no. authentication work like google or Facebook.
Note - Phone no. authentication is working perfectly but the data is not storing in server and local. (phone no. authentication is storing in Firebase but not on server).
when I put phone no. it authenticates successfully but then app says "App is stopped" other than going to "main_menu".
please help me ... I am in trouble\
code of login_A where google and facebook authentication takes place, i added a button here which sends me to login_Activity where phone authentication takes place.

回答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.
