Scribe OAuth not working on android, error 500

Question

I am using the below code to access a Magento api. I have used scribe to complete the Oauth process in which i am using fixed access token so I bypassed few steps of OAuth. Below program works fine when executing as java project but when I am trying it with android it always respond with error 500, service temporary unavailable. I have included CommonsCodec in both project to have similar encoding. during debug i am getting every thing same except response.

Please suggest what am I missing or, how alternate way to accomplish the same.

package org.scribe.examples;
import java.util.Scanner;

import org.scribe.builder.ServiceBuilder;
import org.scribe.model.OAuthRequest;
import org.scribe.model.Response;
import org.scribe.model.Token;
import org.scribe.model.Verb;
import org.scribe.oauth.OAuthService;

Scribe is not meant to be used in android as per my research on scribe current library. Finally i got it working by using oauth-signpost library it's working without any problem and its easy to integrate.

all you need to do is to include signpost-commonshttp4-1.2.1.1.jar and signpost-core-1.2.1.2.jar

 public OAuthConsumer getOauthConsumer() {
    OAuthConsumer consumer = new CommonsHttpOAuthConsumer(COUNSUMER_KEY, COUNSUMER_SECRET);
    consumer.setTokenWithSecret(OAUTH_TOKEN, OAUTH_SECRET);
    return consumer;
}

This will provide you OAuthConsumer that can be used to sign request

HttpPost request=new HttpPost(completeURL);
        getOauthConsumer().sign(request)

that's it you are done. Happy coding :)

@RQube I am unable to get JSON from Magento REST API using above code. How to get that?

@OsamaMohammedShaikh I have moved to other project so can't share the code. Post your code in a new question and ping me url then i'll try to find a solution for you.
