I'm working on migrating an Android library to KMP...

I'm working on migrating an Android library to KMP and reading through the following guide on the Android developer site has me confused. In the guide the following quote indicates androidLibrary{} is no longer recommended.
The guide contains the following excerpts:

Note: Since Kotlin Gradle Plugin version 2.2.0-Beta2 and Android Gradle Plugin version 8.12.0-alpha04, a new configuring block exists called android{} alongside the androidLibrary{} one. The androidLibrary{} block is deprecated and will be removed in a future release of AGP, so migrate to the android{} block.

This seems contradictory because adding a new KMP module in my project, it creates build.gradle.kts file that contains an androidLibrary {}. I'm using Android Studio Narwhal 3 Feature Drop and I have the most update to date version of the Kotlin Multiplatform plugin (0.9-251.26094-AS-85).
Furthermore, there is additional code snippets in the guide that use androidLibrary {}. Can anyone lend some expertise on the subject and help clear up my confusion?

The situation could be confusing here:
• The oldest android {} DSL was once available in KMP plugin, but was recently removed. It was used to integrate with "com.android.application" or "com.android.library" plugins
• Temporary androidTarget {} DSL was introduced to free android name, but still support the same Android plugins
• Meanwhile androidLibrary {} name was used by new "com.android.kotlin.multiplatform.library" plugin
• In the recent AGP 8.12 release "com.android.kotlin.multiplatform.library" plugin reclaimed android {} DSL
androidTarget {} will be deprecated in Kotlin 2.3.0 release and removed in some following releases.

Should I migrate over to the android {} DSL or is it safe to continue to use androidTarget {}?

[tapchicoma]

The best approach is to use "com.android.kotlin.multiplatform.library:8.12" + android {} namespace.

As I wrote above androidTarget {} will be soon deprecated.

[Jonathan]

Sorry, I had a typo and I meant to put androidLibrary {} .

[tapchicoma]

androidLibrary {} AFAIK also will be deprecated in some future AGP releases

[Jonathan]

Either way, I will migrate over to android {}. Do you know when the plugin will be updated to use the correct DSL?

[tapchicoma]

and only android {} will stay

[tapchicoma]

<!subteam^S093FP0H16X> is it KMT plugin who maintains this functionallity?

[Jonathan]

Do you happen to know if switching from androidLibrary {} to the newly supported android {} is as simple as changing the name or are there additional changes that need to be made?

[efemoney]

Its as simple as that.

That's some helpful history. We were using the androidLibrary version for a while but lots of the ide features (especially around dependencies) stopped working in androidMain so we went back to androidTarget. I'll have to take a look into the newer one
