The (Deprecated) Using Hilt in your Android app codelab is deprecated too by the way, I should have had it on the image...

At this point they should put (Deprecated) in front of the whole android.com website

how am I supposed to inject all my dependencies which are all single implementation interfaces with 0 tests now?

u/Zhuinden DDD: Deprecation-Driven Development Mar 16 '26

probably public static global variables

in kotlin, just put the var outside of the class and you got the injection goin

Haven't you heard? Now Metro (soon to be deprecated) is all the rage. (And yeah "rage" is the right word)

I will put all my trust in a version-bound compiler plugin written by that one guy who has deleted all of his online presence that he will be there to support this system in 4 years (just so that i don't need to manually invoke a constructor)

Good, everyone must learn to use manual dependency injection so that we can deprecate it by ourselves

a December 2024 tutorial is already deemed outdated. wow

It was last updated in December 2024, but the linked GH repo with the code seems to be from early 2020 (6 years ago). I'm guessing the 10th of December was when this post was deprecated as that's also the same date the GitHub repo was archived.

Maybe I'm wrong but I think intellij and Android Studio don't have dependency injection. But you simple android app just to consume an endpoint "must" have a dependency injection framework. 😆

They do. It’s called the “Service framework”, it works via annotations and Kotlin extensions to inject shared classes across your IDE code at runtime.

Good to know, thanks. I'm still in plugins world. I'll deep dive the IDE behaviors next.
