Package index

This page lists all the Firebase SDKs for Android that have Kotlin extension (KTX) libraries. These KTX libraries enable you to access Firebase Android APIs using idiomatic Kotlin syntax.

The Kotlin extensions (KTX) APIs have been added to their respective main modules. For example, all the APIs from firebase-perf-ktx have been added to firebase-perf under the com.google.firebase.perf package.

This change means that Kotlin developers should now depend on the main modules instead of the KTX modules (when using Firebase BoM v32.5.0+ or main module versions listed in BoM v32.5.0+).

As part of this change, the KTX APIs in every KTX module are now deprecated. As early as September 2024, we'll no longer release KTX modules, and we'll also remove the KTX libraries from the Firebase Android BoM at that time.

If you use KTX APIs from the KTX modules, we recommend that you migrate your app to use KTX APIs from the main modules instead. For details, see the FAQ about this initiative.
