Android Stori Technical Test

A banking application must be made that allows user registration, user login, bank information: balance, list of movements made and detail of the movement.

📜 Problem to solve

The problems to solve are the following: The first view is the one corresponding to the login of the application, and contains a text field for the username, a text field for the password, a login button and a register button.The challenge to meet on this screen will be the following:

• Validate user data and password
• When making a valid login, the home screen (bank account information and list of movements) should be displayed.
• When pressing the registration option, the registration screen should be displayed, which will be the beginning of the Onboarding.

The registration process must consist of the following views:

• User data: Email, password, name, last name
• Take ID photo: Take a picture of the ID.
• Success screen: Show a success message “Tu cuenta ha sido creada exitosamente”.
• Home Screen: It will be the main screen, the one that the user accesses once he makes a correct login.
• The data collected in the Onboarding must be stored in a database that the candidate must create in Firebase.
• The candidate must also create test data in Firebase with movements to be able to perform a user login without having to create an account.
