How to Retrieve data from Firebase Database in Android Studio Retrieve data from Firebase in Android

I love the very clear tutorial but it is hard to apply this in a different situation for a beginner like me so please explain the general idea. Perhaps.

this is not working for me, when i click go with nothing in the fields the warning shows, but if i place anything else in the input boxes and press go, nothing happens

pls hlp, the password is not retriving for firebase. It says null

It's not a good idea to tell user that user exist but password is wrong!!

When I click on go button in login screen my app crashes and no profile screen is opening. What to do?

password from database is always null ?

Assalamualaikum dear I m receiving user info to check about if user exists or not without auth. Even my database rules are open. Any help please??

Hello taimoor thanks for tutorial
I have an error when I enter my username and password and click on the GO button the app crashed

Great video.
I think it's important to mention hashing the password with a secure hashing algorithm such as as argon2, scrypt, bcrypt (not md5). It's essential to hash passwords with a secure hashing algorithm.

wa aleikoum salam GREAT video Teimoor , just here "reference.child(phone).setValue(userHelperClass);" when you define the USER ID as the phone number then in isUser() method you set the ID as Username " String passwordfromDB = dataSnapshot.child(userEnteredUsername).child("password").getValue(String.class);"
I followed your videos from beggining and this error took me a whole morning to notice it
