having problems since days with Oauth android + signpost

[Tonypower24]

Hello

I am trying to authenticate with goodreads using signpost on android but

do I need the callback_url for android applications ?
I am using these libraries
signpost-core-1.2.1.2.jar
signpost-commonshttp4-1.2.1.2.jar
commons-codec-1.7

I have setup everything but I am getting Communication error servicer provider null and the browser is not launched

Please help me I am doing a university project

my problem is solved
This is happening because calling on UI thread I used AsyncTask Class

But I am having a problem with calling api methods
I get Exception warnings

please someone tell me how to do call method such as getting userid

I'm not sure what you mean, can you provide more details?

I successfully established authentication with goodreads and I gotaccess token but now I don't know how to use the access token to call api methods like getting user id with OAuthconsumer class in signpost library of Android ?

[Michael]

Can you post the code you've got this far? (please remove api keys before doing so)

[Tonypower24]

here is the code

NOTE:
api keys are used in class Constants
class where I call to get userID: MainMenuActivity
MainActivity-Launcher: LoginActivity
Class that are not used: ProxyHelper,Request,Response,ResponseParser

Sorry for taking so long. Have you taken a look at this example?

Should work similarly to that.
