hsccorp / testhttplibs

This is a sample project used to compare different HTTP libraries available on Android

A demo project to test various Http libs available in Android. Libraries demo'ed in this are : HttpURLConnection, OK HTTP, Retrofit, Volley.

The demo has been organised so that each component is readily usable.

To view code for HttpURLConnection, go to the folder : app/src/main/java/com/aggarwalankur/testhttplibs/httpurlconxn

To view code for OK HTTP, go to the folder : app/src/main/java/com/aggarwalankur/testhttplibs/okhttp

To view code for Retrofit, go to the folder : app/src/main/java/com/aggarwalankur/testhttplibs/retrofit

To view code for Volley, go to the folder : app/src/main/java/com/aggarwalankur/testhttplibs/volley

---

Volley has been added as a github project, so you may use the command : 'git clone https://android.googlesource.com/platform/frameworks/volley'

to clone the project and then import it as a dependency project

---

To use this demo, you need an API key (by signing up here : https://www.themoviedb.org/documentation/api ). This API key is not required for Volley, Retrofit, OK HTTP or HttpURLConnection, but is required for the HTTP requests which are used to demonstrate the code and image loading capabilities in this demo.

Once you have the API key, place your API key in the following file : %USERHOME%.gradle\gradle.properties

The above gradle.properties should include a line like this : MyMovieDbApiKey = "your-api-key"
