Volley is a Google library for Android that makes networking and remote image loading easier and faster.

Written by Ficus Kirkpatrick and his team, Volley is a library released by Google at I/O 2013. The Google Play Store and a number of apps by Google use this library to perform network requests and remote image loading. The developers at Google claim that network requests performed through Volley are up to 10 times faster than other libraries according to their tests. There is also an official documentation and a Github.

You can clone the GIT repository by running this command:

git clone https://android.googlesource.com/platform/frameworks/volley
