I'm using Twitter4j in my java app. working fine and able to get the tweets. I'm using the same formats and code in my android app. I kept the auth secret key in properties file inside package folder and also in asset folder. but i'm getting the following error. 

11-30 13:35:46.487: W/System.err(737): java.lang.IllegalStateException: Authentication credentials are missing. See http://twitter4j.org/configuration.html for the detail.

The following are the codes i'm using in my aysnctask in post execution method. 

Twitter twitter = new TwitterFactory().getInstance();
        List<Status> tweets;
        Paging paging = new Paging();
        paging.setCount(1);
        tweets = twitter.getUserTimeline(paging);

        for (Status tweet : tweets) 
        {
            TweetMsg = tweet.getText();
        }

Do i need to add anything in Manifest file?

  • In the first link, for twitter4j, the application should be browser type. But my android application is not a browser and i just need to take the tweets form the twitter account. – Vignesh Nov 30 '12 at 09:14

The above link uses REV 1 oauth, which no longer works. I have written a small Eclipse project that authorizes twitter with REV 1.1:

  • Nice example. The only thing I can't figure out is the callback URL step. Would you mind sharing what that is set to on the twitter dev site? – Matt Aug 27 '13 at 05:02
  • Nevermind. Apparently you just need *any* valid url (e.g. Google) to *enable* callbacks, and then the actual URL gets overwritten dynamically by the request. – Matt Aug 27 '13 at 05:13
  • For whatever reason, the project works just fine by itself. But when I paste it into my existing app, the login page callback goes to mobile.twitter.com rather than returning back to the TwitterTime activity – Matt Aug 27 '13 at 15:38
  • So it turns out that it puts the appName in the Callback URL, so if your appName has a space in it, it fails. – Matt Aug 27 '13 at 16:23
