Repository is archived, use the AndroidX KTX libraries from the official AOSP repository for any active development.

So what is it?

This was an early repository for Android KTX, a set of Kotlin extension functions for Android app development. Kotlin extensions let developers write shorter and more readable code by adding convenience methods to existing Android classes. The repository is no longer active. Google moved development of these libraries into the main Android open-source codebase (AOSP), under the AndroidX umbrella. The README directs anyone with bug reports or feature requests to Google's issue tracker, and directs contributors to the official AOSP repository instead. No new development, issue tracking, or pull requests happen here.

Copy-paste prompts

Prompt 1

Android KTX is now in AndroidX. How do I add the current AndroidX KTX libraries to my Android project in place of the archived android/android-ktx repo?

Prompt 2

What kinds of Kotlin extension functions did Android KTX originally provide for Android development, and what shorter syntax do they enable?

Prompt 3

I found a reference to android/android-ktx in an old project. How do I migrate to the equivalent AndroidX KTX artifacts in my Gradle build file?
