Hi Folks,

I am encountering the following dexing error while attempting to build an Android app.
The Android App depends on an SDK which is written in KMP.
This error popped up after I upgraded kotlin("multiplatform") version "1.9.23" to kotlin("multiplatform") version "2.0.0" in the SDK.

BUILD FAILED in 43s

error Failed to install the app. Make sure you have the Android development environment set up: <https://reactnative.dev/docs/environment-setup>.
Error: Command failed: ./gradlew app:installDebug -PreactNativeDevServerPort=8081
Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

Any suggestions on how to resolve this?

Thanks in advance.

Seems like your react native project is not compatible with Kotlin 2.0.
