Sign-up Activity

Many users ask, “how do we save the user information locally so that the information stays even after the App has been closed?” the answer is file. Using file component, we can save the data locally, and retrieve it next time the App starts. Start by adding a new file component in Signupactivity.Jav...

When we start the application, we will want to greet the user with a login page. On this screen, user will be able to perform two actions: logging in and signing up. This is how I designed my login page:

Here is the logic for the Login_Button clicked event:. If the user enters the Username/Password, validate the length. If they’re both greater than 0, we want to retrieve the information from the data we previously saved. If valid, log the user in, otherwise show an error message.

Last but not least, this is the screen that shows up when the login is complete. Pretty simple right? Even though I didn’t apply this concept, you could possibly pass the username through the Intent if you’d like and welcome the user with the message “Welcome username!”. Just a thought :-)
