I am still discovering funcionalities of both, but I have one question on my mind.
Why to use Picasso over OkHttp?
OkHttp supports pretty much the same thing as picasso, is just that picasso is simpler to use for loading and caching images....
Is there some other important thing that I miss, and that is not included in OkHttp?
And if I use Picasso, do I still need to import OkHttp or it is already included in picasso?

Picasso is an image downloading and caching library for Android.
OkHttp is HTTP & HTTP/2 client for Android and Java applications.
So, the libraries have completely different purposes. Picasso is completely focused on the image handling. For instance, you cannot use OkHttp to resize an image...to define the crop model to apply...etc
You can use Picasso with OkHttp if you want.

How to chose between: Volley and Retrofit
If you are :
Making Requests then I would like to say though both frameworks are capable of the same outcome, Retrofit is capable of accomplishing this without customization. However, if you are implementing multiple requests within your application, and I suspect you are, customization may be necessary within Retrofit. Though that could be the case, at the simplest level Retrofit has the easier solution.
Downloading Files(Image): Being able to make file requests was a pretty large factor in the making of our decision. Volley comes packaged with a loader specifically designed to download images for you. Packaged along with the loader is a custom view called the NetworkImageView in which the developer only has to hand a URL and an ImageLoader to and Volley does the rest. This view is specifically targeted to work well with list views and allow for automatic cancellation of requests when the images parent view is destroyed. On the contrary, Retrofit does not easily support image downloads. To accomplish what we are able to with Volley, one would be required to download and include another library in your project such as Picasso. So here Volley is a better solution.

This question is actually not about the coding, so I don't put any codes here.
While looking into the Volley library, I found out that some part of the APIs contain classes (e.g. classes of the org.apache.http packages) that are now deprecated in Android API level 22.
As I'm concerned about getting adjusted to the newest API environment, do you think it is still worth using Volley or would you recommend using other libraries such as OkHttp or Retrofit?
Check out the detailed response:
Comparison of Android networking libraries: OkHTTP, Retrofit, and Volley
Personally, I went native to keep things simple and robust. Using it for JSON responses and occasional images with no problem and I don't think they will deprecate HttpURLConnection anytime soon.

What is the preferred way of caching different objects (including images) on Android? My goal is to cache some data for quick access, and to keep them available for longer time (for days).
Thanks!
Use a disk cache. Jack Wharton's DiskLruCache is very good https://github.com/JakeWharton/DiskLruCache.
It will save what you want to disk and read from it, and you can build around it to set max-age values for cache.
use Volley for the better caching of images and objects. Its a faster library for android to load data from web.

I just want to know the differences between Android-Universal-Image-Loader and ImageLoader.
Which is better? Thanks!
Well both are image caching library used for lazy loading images (a process where images are loaded at last just like in a webpage) and other stuffs I used universal image loader and found it to be fantastic. I have not used the other library yet but looking at the github repo it looks promising and offers similar features. The only way to know which is better is by trying it yourself. If you do please let us know.

Why using a framework to make Http requests in Android instead of using its own classes to make this? [closed]

There are many frameworks to make http requests in Android, like Retrofit and Volley. But also, Android has its own classes to make this type of request, like HttpURLConnection and HttpClient
So what is the advantage of using some framework like these mentioned?
My doubt is if there is some big advantage in make requests using some framework, instead of using Android native classes.
The advantage is things like retries, restarts, threading & synchronization, and state management will be handled for you. This comes at the expense of configurability, but it's not a huge expense.
