Android KTX is a set of different extensions for the Android framework and Jetpack. The Android KTX extensions are themselves a part of Jetpack and can be added to your project as a simple Gradle dependency. The functionality provided by Android KTX is aimed at making Android APIs more Kotlin idiomatic by taking advantage of features such as extension functions and higher-order functions.
To make the dependency more lightweight, Android KTX is broken up into several smaller dependencies, depending on the functionality they offer. Some of these are as follows:
- Core KTX
- Fragment KTX
- SQLite KTX
- ViewModel KTX
- Navigation KTX
- WorkManager KTX
The entirety of Android KTX provides a great deal of useful functionality. In the following sections, we're going to explore the functionality provided by two specific modules: Core KTX and Fragment KTX.
