Here is a builder I created to build the OAuth v1 Authorization header. You may find it useful.

Example usage calling Twitter:

String authorizationHeader = new OAuth1AuthorizationHeaderBuilder()
         .withMethod("POST")
         .withURL("https://api.twitter.com/oauth/access_token")
         .withConsumerSecret("twitterConsumerSecret")
         .withTokenSecret("your_oauth_token_secret")
         .withParameter("oauth_consumer_key", "your_consumer_key")
         .withParameter("oauth_token", "your_oauth_token")
         .build()
