Android Volley Library Tutorial

Volley is a networking library that manages network requests and their response caches without the developer having to write a lot of “boilerplate” code.  Volley implements tools that allow for simultaneous requests to run on a pool of threads that can be given priority over one another.  All of this is done, while implementing a transparent cache that allows for quick reloading of data.   It is, however, not for everything.  Responses are delivered whole in memory, so it is less than ideal for large downloads such as music and movies.  It is alternatively geared towards smaller requests such as JSON files, images, and other files of that size and nature.

Some features of volley :

  1. Request queuing and prioritization
  2. Effective request cache and memory management
  3. Extensibility and customization of the library to our needs
  4. Cancelling the requests
