Modern Android App Development with Kotlin

Kotlin for Programmers

This module is for anyone who is looking to build their own Android applications. Ever since Google announced that Kotlin is the language of choice for Android development, Kotlin has become increasingly popular.

In this module, we’ll take a hands-on and project-based approach to develop Android applications. We’ll work with the most common tools that Android developers use every day, including Kotlin, Groovy, and XML. As we continue to learn, we’ll build a fully-functional Travel Blog Application that will be a great addition to our portfolio.

By the end of this module, we’ll have tangible experience in building an Android application and we’ll be ready to build even more complex projects.

This chapter covers how to create a login screen for Travel Blog Application. You will  learn how to:

- Work with input fields & keyboards
- Validate input data and show errors
- Show a loading indicator
- Prevent user interactions during loading
- Launch a screen
- Persist a login state
- Apply custom styles to change the look & feel of the user interface

This is the final output of the screen which we are going to build through this chapter.

This lesson provides a general idea of what kind of login screen we will build in this chapter.
