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.

What of the following is not a Kotlin exception?

What of the following is not a Kotlin exception?

`try` is used to define a block of code to be tested for exceptions.

`catch` defines the code that’s going to be executed.


The `try` and `catch` methods don’t come in pairs, and we can use one or both.


The `try` block can be followed by either a `catch` block or a `finally` block.


Which statement is not true about `try` and `catch` statements used for exception handling?

Which statement is not true about <code>try</code> and <code>catch</code> statements used for exception handling?

Which is not an exception handling mechanism?

Which is not an exception handling mechanism?

Errors are problems that an application struggles to recover from, while exceptions can be handled and an application can recover from them.

Errors are unpredictable, and a programmer can’t specifically tell when they’ll occur. However, `outOfMemory` exceptions are predictable as far as exceptions are concerned. That’s why they’re handled way ahead of time using try/catch methods.


Errors are usually related to system resources, while exceptions usually develop when the program is being written and occur at compile-time or run time.


Errors can occur at both compile-time and runtime, while exceptions can only occur at runtime.
