In my app, First, I am verifying phone numbers by using phone authentication of firebase.
I am doing this process in the OTPVerificationActivity class. Every thing is working fine in this class, I am getting the OTP code also and the user gets signed in.
If the phone number is verified, then I am verifying the email by sending the verification email. I am doing this process in the EmailVerificationActivity class. In this class first, i am checking is the user exists or not. if the user is there, then I am logging out the user.
Then i create the account using createUserWithEmailAndPassword function. After this, i want to send a verification email to the user.
PROBLEM:- Now the problem is, after creating the account,onCreate method gets called again. Due to this, I am unable to send the verification email and the further task. So how to stop onCreate method from getting called again.
NOTE :- I tried to run only
EmailVerificationActivitynotOTPVerificationActivity. In that case every thing was working properly. I was able to send verification email and also able to verify the user. But when i am using theOTPVerificationActivityandEmailVerificationActivitytogether i am getting this problem. So please help me to solve this problem.
