Build an Android app that displays Marsian photos in Kotlin with ViewModel and Repositories tested with Unit Test
What you will learn
Create an modern Android application with Jetpack Compose in Kotlin
Organize the code with separate layers
Use Room and Retrofit
Understand the basic of Flow and Kotlin coroutine
Description
During this course, we will create an Android application that will display photos taken by the rovers on Mars.
This app will use all the latest Jetpack technologies :
- Compose (no more XML)
- Hilt (Dependency injection library)
- Room (Jetpack component to create a lite database)
- Retrofit (Simple libraries to make network request)
- Coroutines and Flow (To create asynchronous tasks and request our database)
You also use ViewModels with Jetpack Compose.
With this example, you should be able to create an Android App to the industry standard.
Navigation with Jetpack Compose could be challenging, so we will create a simple example with 4 screens and a BottomNav to understand it.
Your productivity will be improve as Jetpack Compose is easier to write and reuse.
You will improve your knowledge of Kotlin. If you still use Java, this course is an opportunity to learn.
Compose is a new way to create a UI on Android. It is more concise and reusable. Therefore, it helps to develop faster Android applications.
In this app we will use Jetpack Compose Components:
- Card
- LazyColumn
- Column
- Row
- AsyncIamge (from the Coil lib to display an image from a server)
- Text
- Image
- NavHost (to use navigation)
- NavigationBar
- NavigationBarItem
We will also see how we can use a modifier to define padding.
