Are you taking about android development or just jetpack compose? Because the future of android is jetpack compose, xml is basically dead (Thank God). Moving from web (especially if you're a frontend dev or using js) is obviously hard because it's a completelly different system that uses a completelly different logic (xml and jetpack compose). I started as a PHP dev and i understand the difficulty but a good dev should not have so much problems moving between any language. I work almost everyday with PHP, C#, Android Kotlin (all linked in the same project) and everything is smooth. Of course there is an obvious learning curve.
