Transmitting Network Data Using Volley

Video

Volley: Easy, Fast Networking for Android

Volley is an HTTP library that makes networking for Android apps easier and most importantly, faster. Volley is available on GitHub.

Volley offers the following benefits:

Volley excels at RPC-type operations used to populate a UI, such as fetching a page of search results as structured data. It integrates easily with any protocol and comes out of the box with support for raw strings, images, and JSON. By providing built-in support for the features you need, Volley frees you from writing boilerplate code and allows you to concentrate on the logic that is specific to your app.

Volley is not suitable for large download or streaming operations, since Volley holds all responses in memory during parsing. For large download operations, consider using an alternative like DownloadManager.

The core Volley library is developed on GitHub and contains the main request dispatch pipeline as well as a set of commonly applicable utilities, available in the Volley "toolbox." The easiest way to add Volley to your project is to add the following dependency to your app's build.gradle file:

dependencies {
    ...
    compile 'com.android.volley:volley:1.1.0'
}
You can also clone the Volley repository and set it as a library project:

  1. Git clone the repository by typing the following at the command line:
    git clone https://github.com/google/volley
    
  2. Import the downloaded source into your app project as an Android library module as described in Create an Android Library.
