In this video, I am going to start with the database part of the login and sign up activity. When user signs up, it will store the details of that user in the database. We'll create a contact class and table to store all the information about each user that signs up using this app.
Then in the login activity, when a user types the username and password, it'll will search for that username and find respective password. If the typed password matches with this one then user will successfully sign up else it will show a toast error message.
There will be 2 more parts which will be uploaded tomorrow.
