Yes, but right now it's easier to create projects in Android Studio with the
KMM plugin. There is an
IntelliJ KMM plugin, but it's still in early-bird testing. Once you've created a project, you can open it in IntelliJ just fine. Or you can manually create the multiplatform modules and build files as well.
I'm targeting JVM, Android, iOS, macOS, and JS in codebases I consider stable and other native targets that are just less tested. There are
many others successfully deploying KMP in production to various targets. In general, it's mostly the KMP tooling that's still incomplete (like these IDE plugins). KMP code itself is stable. There are just some APIs that may potentially change in the future (they're marked as such in Kotlin 1.9). You can see the stability of individual components
here.
