Android Volley Examples

In brief: here is the git project with the Volley examples/samples

In details:

Volley was announced just few days ago at the I/O 2013. It is a library/framework that helps the developers to create more easily applications that use network requests, and more precisely REST requests. I was very exited to give it a try but unfortunately I found that there are no examples and tutorials. Now, after experimenting with it, I will try to fill to some extend that gap.

Features of Volley:

• Nice and easy API for executing REST requests;
• unifies the mechanism for REST requests by abstracting the "bottom" layer, i.e. you don't care any more about HttpClient or HttpUrlConnection. On lower versions (<= GINGERBREAD) Volley uses AndroidHttpClient and no higher it uses HttpUrlConnection;
• it is very fast. In the I/O presentation the guy states that they tested it at Google with several different apps and Volley was clear winner in all categories;
• it is extensible -- you can use it as a basis to create your own custom type of requests (and response handling/parsing)

You can find the project with the examples at Github:

git clone git://github.com/ogrebgr/android_volley_examples.git


During the import of the project you may need to change the project name to "Volley Examples" otherwise you will end up with a project called "Act_Main".

You will need also the Volley itself:

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

After importing Volley you may need to mark it as a "Library project" in order to include it in the example project.

Currently there are  6 examples:

• Simple request -- request against web server and fetches the body of the response. Uses StringRequest. 
• Using  Volley with GET and POST parameters
• JSON request -- request against web server and parse the response as JSON. Uses JsonObjectRequest
• Gson request -- request against web server and returns Java object that was created using Gson (i.e. converting the result string into JSON and then into Java object.). Uses "custom" made GsonRequest class.
• Image loading -- request that loads image from server using ImageLoader.
• Using cookies
• Using Volley with newer external HttpClient (4.2.3)
• Using Android Volley With Self-Signed SSL Certificate
• Dynamic ListView with NetworkImageView, "endless" paginatio, JSON parsing, etc.

In the next days I will add more examples.

All comments will be welcomed. If you wish to provide samples/examples that you want to be added to this project -- feel free to fork or write me an email  (address is here).
