In general, tasks performed in ViewModel are background tasks like network requests, database operations, etc. The most popular use case of LiveData is the communication between View and ViewModel.

LiveData is a data holder class that can hold observable data which can be observed using Android components such as Fragments, Activities, etc. In situations where the Fragment or a Jetpack is depicted as a screen, we are required to develop an existing instance of the related ViewModel. In the coming years, it is believed that we will transition to Jetpack composable functionalities instead of Fragments.

In advanced Android app development, we are moving towards Fragments instead of activities. This can also work where you want to limit a task to the lifespan of a particular component. When using ViewModels and Kotlin coroutines, it’s important to be within the scope and launch background tasks that run for longer within that scope that these tasks can be canceled whenever required. Let’s explore the five Kotlin extensions that can make Android development a lot easier. KTX extensions utilise Kotlin’s features to offer developers brief guidance for working with Jetpack and other APIs.

Android KTX is a collection of Android libraries with Kotlin extensions that help simplify coding when working with Jetpack and other Android libraries.
