Introduction

You will probably find it hard to get an app that doesn't communicate over the network. Communication with the internet is used in almost all the apps, be it a file-sharing app, streaming app, social network apps, or something else, the list goes on and on. There are many variables that you need to think about when you want to add network communication features to your Android apps. For example, you can't run it on the main thread, and network requests are always performed on background threads. Apart from that, you also need to detect when the network request fails, so as to give feedback to the user about what went wrong. In this chapter, we will address how to efficiently make network requests in Kotlin.
