If someone used a real-time database, replace part of the code: DatabaseReference reference = FirebaseDatabase.getInstance().getReference("Users").child(userID); reference.addValueEventListener(new ValueEventListener() { @Override public void onDataChange(@NonNull DataSnapshot snapshot) { User userProfile = snapshot.getValue(User.class); if(userProfile != null) { fullName.setText(userProfile.getFullName()); email.setText(userProfile.getEmail()); age.setText(userProfile.getAge()); } Previously, set the get and set methods in the 'User' class Thanks for the great tutorials! You helped me a lot.
I followed your tutorials about logging in and registration, and they helped me a lot. I've just got this problem, when I try this tutorial, why I can't display the values?
please make video on shared preference when sure open the app first time then show login screen and then user open the app second time then do not need the login direct redirected on main page screen please make a video on this concept
Thanks for your great tutorial but I got a problem, my app is crashed when I call function addListenerForSingleValueEvent, do you have any idea? Thanks a lot ^^
error- Run console: Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String com.google.firebase.auth.FirebaseUser.getUid()' on a null object reference at com.test.test.ProfileView.onCreate(ProfileView.java:34) any solution to this error ?
Great video! I was wondering how you would go about adding this sort of functionality to fragments within my app, such as a login/register fragment or a profile information fragment that fetches your data from firebase.
Hello sir. This video's are so good and benefits for me. I am currently doing my fyp . Sir in this video I can see user display profile there is only logout. Can u create same like this and insert this feature like user profile name age email that can able to change with edit, update and delete button . When they change here it automatically change in firebase database. Like. That
Hello kind sir, all of the video is great and i understand thanks to you but when i do the display data my app crashes whenever i login, i just cant seem to get the data from the database, do you have any idea what is the problem ?
I tried this but on an additional page called UserProfile, so once the user gets to their main activity they would click the profile button to get there and they can view/edit their user details, this isn't however working at the moment and doesn't even display the user details, any knowledge on why?
Great step by step , although the values in the profile are not showing for me in the profile but i do see them in the Realtime database , any suggestions?
I am wondering how to do this with web development, so I am creating new users with firebase and it saves on the database but I have no idea how to make the profile on the website Can you help?
hey, for some weird reason I can't get the names from the database, I think it's because the user is always assigned as null and I don't know what to do, I would appreciate your help.
perfect tutorial thanks alot ! you can add one more video about, if i logged in then i close the app then reopen it i have to login again, it must take me to the Profile Activity directly.. i hope if you can complete this playlist because it's perfect but it lack only this thing ! again thanks for the playlist it;s really good..
Actually i found out how to do that guys. just add function in the main activity in the end. @Override protected void onStart() { super.onStart(); FirebaseUser user = mAuth.getCurrentUser(); if(user != null){ startActivity(new Intent(MainActivity.this, ProfileActivity.class)); finish(); } } } you;re welcome guys
@@CodeWithMazn actually thank you. i want to ask you about something. i already did the login part and i want to merge between two projects and i couldn't i tried a lot of ways but also i couldn't. can i contact you on instgram and tell what should i do or can you make a tutorial about it!? sorry for asking so much but you're so awesome and clear with your videos so that's why im asking YOU not someone else..
You didn't show if the user ID has changed. I followed the steps in this tutorial and it's still giving me random user ID info. How can I make it so that user ID matches like their email or name?
To those who can't obtain data from Firebase: Replace: reference = FirebaseDatabase.getInstance().getReference("User"); to: reference = FirebaseDatabase.getInstance("You might need to put your URL from real-time Firebase database ").getReference().child("Users").child(userID);
For everyone who cant get the information to pop up, fear not! I have the solution change: reference = FirebaseDatabase.getInstance().getReferenceFromUrl("Your firebase url here") .child(FirebaseAuth.getInstance().getCurrentUser().getUid()); and reference.addValueEventListener(new ValueEventListener() { basically just change the Singlevalueevent to valueeventlistener You're welcome!

please how to use firestore service instead of realtime , I am having sleepless nights trying to work on it

You didn't show if the user ID has changed. I followed the steps in this tutorial and it's still giving me random user ID info. How can I make it so that user ID matches like their email or name?
i have the same issue but the uid is incrementing when i create another account it matches the uid from the previous user that i created
great
Can you please tell how to change the fullname when user wants to change it?
Check Firebase documentation. I will upload a video soon on how to update data in Firebase
@@CodeWithMazn please make it ASAP with respect to this series
Can you give some resources on how to edit profile
You can check Firebase documentation on how to update and delete section. firebase.google.com/docs/database/web/read-and-write#update_specific_fields
@@CodeWithMazn thanks
not working
source code please
To those who can't obtain data from Firebase:
Replace:
reference = FirebaseDatabase.getInstance().getReference("User");
to:
reference = FirebaseDatabase.getInstance("You might need to put your URL from real-time Firebase database ").getReference().child("Users").child(userID);
i still cant do it :D
For everyone who cant get the information to pop up, fear not! I have the solution
change:
reference = FirebaseDatabase.getInstance().getReferenceFromUrl("Your firebase url here")
.child(FirebaseAuth.getInstance().getCurrentUser().getUid());
and
reference.addValueEventListener(new ValueEventListener() {
basically just change the Singlevalueevent to valueeventlistener
You're welcome!
