Humble Chronicles: Managing State with Signals
Is this similar RxJava, the reactive extensions library for https://github.com/ReactiveX/RxJava ? I have made that work in Clojure in production.

How to do threading in Android.
Since you mentioned java, there is RxJava and RxAndroid. Google general recommendation now is to use kotlin coroutines if you're considering writing your app with that.

It hurts
It's very quick though. In terms of the correctness of the syntax, I've never seen an issue while translating a single file or a single function. When I took the entire RxJava code base 5 years ago, right clicked on the source folder and converted to Kotlin, I found lots of problems. File by file I've never seen any issues though, but I also haven't done it much.

must known frameworks/libs/tech, every senior java developer must know(?)
You all beat me to MapStruct and Testcontainers. Honorable mention to RxJava, which I use in Desktop apps.

What are the most common used (3rd party) libraries and frameworks used in Android development?
Concurrency: Kotlin coroutines for general use, Rx or Flow for reactive programming (you can technically use Rx for regular concurrency as well, but not really what it's meant for)

Notification when item add to a ListView
If you're just looking at making a service call on a regular interval and notifying the user when there's an actual change in data, you can also look into RxJava https://github.com/ReactiveX/RxJava. From here you can "subscribe" to your service call, and then every time you make your service call you can have it look for changes compared to the previous emission .distinctUntilChanged() and then only notify it's subscribers when it notices an actual change. From there you can trigger a local notification and push to a LiveData (assuming MVVM) or otherwise update the UI to match as well.

I built a wallpaper app that takes images from Reddit (+ free promo codes)
Do you mean what I use to show the images? I am using the Glide library, you can find more information here: https://github.com/bumptech/glide

GMMP randomly fails to display embedded artwork
as mentioned in the other post i don't have too much insight in the art loading because its using https://github.com/bumptech/glide for all image loading. Resolution is the only thing i know for sure can prevent an imagine from successfully loading, whether or not that resolution is fixed or if its dependent on the device I have not been able to determine

Does downloading media start fetching media from the servers again or does it fetch from the current session cache?
Ah, yes, downloading images as a files works completely differently from displaying images and it doesn't use any cache. Though in theory you could rewrite downloading logic to use the same mechanism as display (which is Glide)

You can also take a look at Coil, Picasso or Glide which usually have some kind of crossfade animation when the image loads.

I made a free fitness app with the most popular Reddit workout programs. Use it to kickstart your fitness journey and end 2021 strong!
Shortly said, they use React generally with fast-image and Glide for better loading of images Hermes JS Engine for app optimization. The app itself seems to generally use Kotlin and a few Java libraries and they also implemented Sqlite but I'm not sure about the use case for it probably they use it for progress though (The Developer/Marketer needs to confirm this), lastly they seem to use IntellJ Idea for programming and probably compiling
