Best REST Client Framework/Utility on Android [closed]

I'm about to build an Android application that will use a RESTful Web Service. I don't want to write the REST client by myself, as I want it to be as effective and stable as possible (this is the first time I'm using REST).

Are there any (free) frameworks or utilities avaibale for Android/Java that I can use in my project?

What is REST client in Android?

REST Client in our case is the Retrofit library that is used on the client side (Android) to make HTTP request to REST API, in our case, The Movie DB API and also process the response.

Restlet is an excellent REST framework and has an Android edition.

Any HTTP Client library should be perfectly adequate to interact RESTfully with a web API. E.g. http://developer.android.com/reference/org/apache/http/client/HttpClient.html
