Which Android libraries have brought you to tears of joy?

Question

Android

The essence of the question is to find out which libraries and frameworks make your development convenient, fast, high-quality or just pleasant. However, it is expected that you will write a detailed answer, which will not only mention the name of the library, but also what has been improved since applying it.

Answer 1

I recommend this list of "must-have" libraries.

Answer 2

rxjava is our everything. but I think you already know about it

Answer 3

with comments it won’t work, I’m afraid to spread my thoughts along the tree))
Picasso
Retrofi + Gson do
not need explanations
dagger 2 has little experience with it, but the sensations are pleasant

Answer 4

strange, no one remembered the android support library :-D (ahem, somehow it turned out a bit thick, well, oh well :) )
and so - yes, dagger/butterknife for binding and dependency injection
picasso for loading pictures from the
retrofit + rx java network
and there is also a (a little dusty, though) repository in the bowels of the github, which helped me find answers to many questions.Here it is (wow, just looked, there are even some movements!)

Answer 5

UIL, Retrofit, Realm(somewhat), RxJava, DataBinding etc
