Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

New app: xml or compose?
I liked https://github.com/bluelinelabs/LoganSquare for example, but annotation processors are hard to maintain. Look at libraries like Mortar-Architect https://github.com/lukaspili/Mortar-architect or Blade https://github.com/FrantisekGazo/Blade or even better Permissions-Dispatcher https://github.com/permissions-dispatcher/PermissionsDispatcher/issues/775 which actually breaks builds after certain Kotlin versions.

What are the most common used (3rd party) libraries and frameworks used in Android development?
Permissions are generally a pain, but I've used PermissionsDispatcher, EasyPermissions, and RxPermissions at various times

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.
