hello i have this error

Provide the code, otherwise it will be difficult to help…

I wanted to add a new activity and it brought me this error

You can't use two Kotlin plugins in the same project. You will either use

id("org.jetbrains.kotlin.android")

(or

kotlin("android")

which is the same) for a Kotlin Android app or library or

kotlin("multiplatform")

for a multiplatform shared module. In your case, assuming this is a multiplatform shared module, you should remove

id("org.jetbrains.kotlin.android")

.

@Jeff Lockhart thanks
