OAuth 1.0 Requests with Retrofit in Android

Question

I am trying to access a Magento REST API in my Android app, using Retrofit.

What have I tried:

SignPost and OkHttp to sign request using these classes : https://gist.github.com/f2prateek/0deb2d7ddea43e21d39b
Custom Headers having OAuth values

But none of them have worked.

Retrofit 1.7 and OkHttp2.0RC2 don't work well with SignPost (at least the way the article suggest)

And when I downgrade for things to work, I get error HTTP 500 Error saying Internal Server Error

The same credentials work using REST Client plugin for Firefox.

Is there a working solution for implementing OAuth requests with Retrofit, or any other option?

Much thanks in advance.

Give it a try to this fix pakerfeldt's signpost-retrofit (A Retrofit extension to oauth-signpost OAuth Core 1.0a standard) !

Other fixes you can try:

Turned out that the web server expected the Accept parameter in header, which I was missing but Firefox extension was adding.

That made the server return a 500 (sending a response telling about the error would have been wiser though)

Things are working fine now.

Thanks for giving your time!

I have tried authenticating using the magento REST api from plain java code using the scribe lib. So far it worked for me.
