The Android world has many libraries that require annotation processing. You just annotate the code, and it generates all the code behind the scenes for you, making your life easier. Many libraries such as Butterknife and Dagger2 work in similar ways. In this recipe, we will learn how to use Butterknife with Kotlin. For those who aren't familiar with Butterknife, it's a library that binds a view to a field without needing the findViewById calls. It's a household name in the Android development world. In Kotlin, the Kotlin Android Extension does almost the same work and is bundled along with Kotlin. However, if you are migrating your Java code where you've used Butterknife, this recipe will help you.
