Android :: Posting To Facebook Feed From Android App

I am trying to enable users who have linked their Facebook account to be able to post to their wall with one button press as detailed in their docs. Specifically, I do not want to use the .dialog methods provided in the Facebook for Android library, as I want the Publish process to be as seamless as possible.The specific call looks like this in an HTTP client simulator: HTTP POST https://graph.facebook.com/me/feed Content-type: application/x- www-form-urlencoded access_token=&link=http://mylink.com/id/1326&name=What do you think?&description=Description of the link This call runs successfully in HTTP Client on OS X. I originally tried using the Facebook for Android library's .dialog function with "stream.publish" action, but this causes the unwanted dialog to appear. Next, I tried using Facebook for Android's .request function with "POST" parameter, but this function assumes that the body is a byte array and fails in multiple places in the library. Now, I am trying to use the Apache HTTP stack included with Android.Specifically, my code looks like this: String url = "https://graph.facebook .com /me/feed"; ArrayList<NameValuePair> pairs = new ArrayList<NameValuePair>(4); pairs.add(new BasicNameValuePair("access_token", App.facebook.getAccessToken()));pairs.add(new BasicNameValuePair("link", "http://mylink.com/id/"+id)); pairs.add(new BasicName ValuePair("name", question)); pairs.add(new BasicNameValuePair("description", description));The problem is that the response from Facebook is consistently the following: {"error":{"type":"OAuthException","message":"Invalid OAuth access token."}}I know the OAuth access token is not invalid. When I paste the same OAuth access token into HTTP Client, it works like a champ. It seems that creating the HttpPost object's parameters is garbling the complex OAuth access token in some way. Does anyone have suggestions on how to proceed?
