Firebase Authentication with Phone number OTP in Android Studio Tutorial

If you face any problem Plz check if Your SDK contains Google Play Services or not. and also if u are able to use firebase auth successfully or not. and also check ur firebase dependency versions.

So in this video, I have created a Firebase OTP Application using Android Studio.
Using this, a user will input his number and he will get the verification code using Firebase OTP

Even after reading several comments saying the code is not working, code is wrong or sms is not getting sent, I implemented the sms verification functionality using this video and its working PERFECTLY FINE if u follow the steps exactly they are shown in the video. Thank You so much for the video. SMS gets sent and it gets verified also.

yes there is a small problem in the code, especially for those who wish to move to make verification in other activity or fragment.

*. problem: i use to put code required for moving to next fragment or Activity in sendVerificationSMS() function!

*. note: onCodeSent(String s, forceResendingToken) {
super.onCodeSent(s, forceResendingToken);
verificationCode = s ;}

works in background! the assigning delayed so you won't get verificationCode value if call it in sendVerificationSMS() function.


*. solution : put code required for moving to next fragment or Activity in
public void phoneAuthCredential) {

//my own function to change fragment with sliding effect ),

}

*. Note : remeber to remove code required for moving to next fragment or Activity from sendVerificationSMS() function!

This code working fine,
Three things u need to remember:

1. enable (On) the call authentication in the firebase.
2. Phone number in the form of (+country code mobile number, like
3. give permission for sms in your mobile.
