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.

Mastering MVVM Architecture in Android Development using Kotlin

We can design with a GUI layout editor by just dragging and dropping Views.

 It’s part of the Android Jetpack libraries.



It uses flat-view hierarchy, giving it an edge over other layouts.

In `ConstraintLayout`, we can only arrange our UI components in either a horizontal or in a vertical manner.

Which option is not true about `ConstraintLayout`?

Which option is not true about <code>ConstraintLayout</code>?

Gradle is written using the Groovy scripting language.

Gradle automates tasks that would otherwise have been done manually.

Gradle manages dependencies consistently across all builds.

Which statement about Gradle is false?

Which option is not a lifecycle life state in an activity?

Which option is not a lifecycle life state in an activity?

**(True or False)** The `ConstraintLayout` has better performance than a nested layout.

(True or False) The <code>ConstraintLayout</code> has better performance than a nested layout.

The primary constructor must at least have one argument in its constructor.

The class can be an open or an abstract class.

The parameters in the constructor must either be `cal` or `Var`.

Which statement about data classes is false?

Which statement about data classes is false?

 Which method is not an automatically generated method by a `data` class?

Which method is not an automatically generated method by a <code>data</code> class?

What's the correct output of the code snippet below?

```
data class Student(var name:String,var age:Int)

fun main(args:Array<String>){
 val student1 = Student("Peter",23)
 val student2 = Student("John",20)
 val student3 = student1.copy()

 println(student1.equals(student2))
 println(student1.equals(student3))

}

What’s the correct output of the code snippet below?
<pre><code>data class Student(var name:String,var age:Int)

fun main(args:Array&lt;String&gt;){
 val student1 = Student(&quot;Peter&quot;,23)
 val student2 = Student(&quot;John&quot;,20)
 val student3 = student1.copy()

 println(student1.equals(student2))
 println(student1.equals(student3))

}</code></pre>
