Login and Signup using Firebase Realtime Database in Android Studio | Store Data

Welcome to Android Knowledge!

In this video, I have share how to create login and signup in android studio using firebase realtime database. When the user will click on sign up button then the details will be saved in the firebase realtime database. When user will login then it will check the same credentials with the firebase database and if it matches then it will go to the home screen.

[JoshuaG]

Thanks for this video, it helps my thesis.

By the way, will this actually work once i have the app on my phone ? not an emulator.

[jacurry]

Can I ask? when Im logging in the password does not validate and just go login even without matching the registered password. How I fix this to validate first before login

[shinobi]

Hi I'm getting a User does not exist error although my code matches yours in the given updated source code. My guess is the snapshot in the login class is returning null. What could be the solution? thanks

[faizanalimian]

there is a problem with your sign up code as u can keep the spaces blank and it would still say you have signed up successfully and more over it completely wipes out the firebase database and all the users stored in it so any solution on that

[CodeA-hoty]

did you change anything in the rules of firebase? because maybe that's the reason why i'm getting an error. THANK YOU

[fsp]

What's is the architecture are you using in this project?

[anjachi]

I noticed that you have another video that's also about Login and Sign Up in Firebase. Is it different from what you taught here, and if it is, what is the difference?

Love the theme of your videos btw I love purple and white combo too!!

Em um vídeo anterior seu deixei uma mensagem a respeito de algo similar a este tutorial, porem aqui voce utiliza somente uma pagina de cadastro, no meu caso seriam 4 paginas de cadastro onde cada pagina faz referencia a um tipo de dado (Dados Pessoais, Dados Bancários, Dados de Veiculo. etc...). Como no seu vídeo é somente uma pagina, ainda não ficou claro de como eu poderia fazer isto em varia paginas trazendo todos os dados armazenando os no "HelperClass", para depois subir todos de uma vez para o RealTime Database.

Nice video! 👏🏼

Im facing an error and when i run the app, it cant launch the signup activity. Error is for LoginActivity and says "The activity must be exported or contain an intent-filter".

I would appreciate it if you help me.
Thank you!

[michaelangelolozande]
