On Android - my platform - 99% of var usage is just for the sake of dependency injection, which is an inevitable concession because basic building blocks of an app (like Activities, Fragments) are instantiated by the SDK, not your code, so neither your code nor the libraries it relies on have control over it and thus the DI has to happen "on the fly", by mutating fields as soon as it becomes possible. It leaves a bit of a bad taste still, but it's very much a fixed convention and therefore kind of... compartmentalized, I guess. And harmless, because I don't expect Dagger 2 to suddenly misbehave and forget to set a field.
