> I want to pass interviews and do android development for employers Definitely learn plain old Android-style Java, with the usual tools (android studio, etc) then. Most shops are going to be that, and if you want to pick up Kotlin for the shops that are a step ahead then do that. > Thanks for the spectrum, which one would I lead with and expect to answer the most questions in and complete project time trials on React Native in this scenario, unless the company already has at least one (and if it's one they have to be VERY competent) mobile engineers on both major platforms. Fully native is the best results (there's essentially zero limitation) but is the most specialized work. PWA is the easiest, but paradoxically needs a tiny bit of specialization to get native enough that the business isn't embarrassed. Also, with PWA there's lots of hard limits on what the app can do (notifications are a particular bugbear).
