Travis CI state :

An asynchronous, callback-based Http client for Android built on top of Apache's HttpClient libraries.

• Make asynchronous HTTP requests, handle responses in anonymous callbacks
• HTTP requests happen outside the UI thread
• Requests use a threadpool to cap concurrent resource usage
• GET/POST params builder (RequestParams)
• Multipart file uploads with no additional third party libraries
• Tiny size overhead to your application, only 19kb for everything
• Automatic smart request retries optimized for spotty mobile connections
• Automatic gzip response decoding support for super-fast requests
• Optional built-in response parsing into JSON (JsonHttpResponseHandler)
• Optional persistent cookie store, saves cookies into your app's SharedPreferences

You can now integrate this library in your project via Maven. There are available two kind of builds.
