The course focuses on the MVVM (Model-View-ViewModel) architecture in Android development using Kotlin. The MVVM is widely recommended due to its robustness, scalability, and ease of maintenance. It is a valuable skill to have for building high-performance Android applications.

Firstly, you will learn the basics of MVVM architecture and its advantages over other approaches to Android development. Then, you'll start from scratch and create layouts for a news application. Next, you'll use the Retrofit and OkHttp networking libraries and get to familiarize yourself with APIs. You'll get hands-on experience in storing data locally via the Room library. Finally, you'll be introduced to both the repository and ViewModel patterns, as well as how to work with the Paging library and deliver data to our fragments.

By the time you’re done with the course, you’ll be able to use MVVM in your Android projects, interact with APIs, store data locally, and implement pagination.

The `navigation` component helps users navigate through different activities (GUIs) or fragments in an application through simple button clicks or through app bars like the `BottomNavigationBar` or the `NavigationDrawer`.

 It simplifies the process of constructing and linking different destinations by removing boilerplate code because a developer will find it easier to use a `graph` than the conventional method of using `intents`.

Let’s create a navigation graph.


# Create a navigation graph
**Add dependencies**

We will add the necessary dependencies and plugins to our module-level `gradle` file if they’re not there already.

   // Navigation Components
    implementation "androidx.navigation:navigation-fragment-ktx:2.4.2"
    implementation "androidx.navigation:navigation-ui-ktx:2.4.2"

Add the following plugin if it’s not added already.

apply plugin: 'androidx.navigation.safeargs'

To avoid errors when importing these dependencies in the classes, ensure that `gradle` has successfully synced the newly added dependencies.

**Create a navigation graph**

To create `NavGraph` file, refer to this [lesson](https://www.educative.io/courses/mastering-mvm-architecture-in-android-development-using-kotlin/create-navigation-graph).

 Learn to implement a bottom navigation bar to navigate across application destinations.
