is android studio open source? i get different results from every website.
google never says it's foss and it makes sense why theyd not foss it, extend and extinguish. flathub says proprietary, wikipedia says both, im very confused
Android Studio is a fork of IntelliJ IDEA, which is open sourced and free software (under Apache 2.0), with additions from Google (proprietary and closed source, as far as I can tell), so it has components that are both. This is compatible with the Apache license, which doesn't require that derivative works be distributed under the same license.
So, ultimately, Android Studio has some components that are open source and some that aren't.
and is there no other way to make kptlin code?
Kotlin? You have options.
There's always the command line tools with gradle 😉
The regular FOSS Intellij Idea is the premier Kotlin IDE and can do Android too. Though Google is usually a slog to throw their AGP integration code over the fence which sucks because projects sometimes upgrade their AGP quite aggressively.
The code itself is just text, an IDE just gives you fancy integration.
