#Android HTTP Libraries
Volley is Google’s official HTTP library designed to make networking easier and faster for Android developers. Packed with powerful features like transparent HTTP caching, request prioritization, debugging, and tracing, it aims at simplifying the life of developers.
OkHttp is designed to be the most efficient HTTP client. It supports the SPDY protocol, which is the base of HTTP 2.0. Key features include connection pooling, response caching, both synchronous or asynchronous calls, and automatic GZIP compression.
Ion is a simple yet powerful HTTP networking library for Android. Due to a strong focus on asynchronous networking and image loading, it’s more suitable for reusing connections, displaying images, and canceling requests taking too long.
Retrofit is an awesome type-safe HTTP client built to turn your HTTP API into a Java interface. In layman’s terms, it makes loading JSON or XML data into Plain Old Java Objects (POJOs ridiculously simple.
With Retrofit, not only you can define your REST API as an interface in one or two lines of code, but also you’re able to manipulate a number of components via annotations. Moreover, it also offers:
- A separate Rx module
- URL Manipulation
- Query Parameters
- Request Bodies
- Multipart requests
- Synchronous and asynchronous API calls execution
#Android Image Loading and Caching Libraries
Fresco is a lightweight and powerful Android library to manage and display images in Android applications. Taking care of image loading and display, it frees you from the management of images in Android.

- Display of animated GIFs and WebPs
- Streaming of progressive JPEGs
- Extensive customization of image loading and display
- And much more!
PixelShot is an easy to use and intuitive library that you can use to save any View, SurfaceView, and RecyclerView in your Android application in either PNG, JPG, or .nomedia formats. The default image format is JPG and images are saved to Pictures folder in your internal storage with a timestamp next to each image.
PixelShot works as an asynchronous thread in the background, deals with I/O errors, and handles memory allocation for you. You can use it for a number of scenarios, including taking screenshots inside your app to report a bug or improvement.
The way how Android handles APIs and loads images and videos locally or from download has never been efficient for the system and Glide is introduced to deal with the same problem. With a clear objective of facilitating smooth scrolling, it ensures the quick and smooth loading of remote images into the ImageView.
Additionally, Glide also allows you to define fallback images and scale or cache your images. You can do even more complex image stuff, such as media decoding, fetching, resource pooling, displaying video stills and animated GIFs, through a simple and easy to use interface.
Picasso is an exceptionally powerful image downloading and caching library for Android to simplify the process of displaying images from external locations – often with a single line of code.
