Sending POST Request to Internet Using Android Volley

Android Volley Library Tutorial

Android Volley is an library for network operations in android development. It is a very light weight framework and most importantly, very fast for network operations. It has facility to get the raw string, image or JSON data over the network efficently. One of the benifit that I like the most if you can easily use volley in your activity as it automatically sends the request in separate thread. And also maintains a queue for the requests.
Note that volley is not for large data downloads as it holds all the data in memory. For large downloading use the DownloadManager.
Here is the demo video for this app.
