Or consider alternative cross-platform frameworks like React Native or Flutter. There's even a new SwiftUI,
Skip framework for writing multiplatform apps. Most of those will require at least
some kotlin to bridge to the native Android platform, but you can absolutely make Android apps without a Kotlin being the main language.
That said, I think if you give yourself some time to learn things "the kotlin way", you'll find it is a very nice language, and in many ways is objectively better than those other options. And that's not just my opinion, Kotlin was very intentionally designed to fix many of the problems inherent in those other languages/platforms. Yes, it has its own syntax and idiosyncrasies, but if you stop trying to fit Kotlin into the paradigms of other languages, and instead embrace Kotlin as it is, I think you'll grow to like it.
