The app and code in the video are tested and perfectly working. However, I have seen that some of you are facing difficulties and getting some errors, so here is a beginners guide to debugging:

1) Error: Null object reference Solution: This always means you have given the wrong XML ID, just correct it

2) Error: User Credentials not sent to Firebase Solution: Check if you have added all dependencies else do the following:
In Android Studio, go to Tools > Firebase. Click on it. A new tab will open. Click on Authentication > More Info > Email and Password Authentication Link. Another tab will open. Check if the first step shows connected to the database. If not, just click on it and you should be asked for Firebase credentials and on entering that, you will get connected :)

3) Error: App is crashing Solution: Check your logcat section present at the bottom of Android Studio, it will tell you where you have made the error or what caused the error. Just go to that line then and debug.

4) Error: App crashing in emulator: This happens because your emulator doesn't have the latest google play store services. Either update play store or just run it on normal phone

Also, some things to note:
1) Every new user must have unique email ID
2) The password length must be more than 8 characters long
3) Internet must be ON

Hope this helped everyone :)
