Android Twitter4j - TwitterException (No authentication challenges found.)

Question

I am making an application which gets just tweets from a specific page in android. I am using the twitter4j library version 3.0.5. Here is my code below:

    @Override
    protected String doInBackground(String... credentials) {
        // TODO Auto-generated method stub
        oAuth_ConsumerKey = credentials[0];
        oAuth_ConsumerSecret = credentials[1];
        accessToken = credentials[2];
        accessTokenSecret = credentials[3];

        System.out.println("Credentials -------- " + oAuth_ConsumerKey
                + "\n" + oAuth_ConsumerSecret + "\n" + accessToken + "\n"
                + accessTokenSecret);

        ConfigurationBuilder builder = new ConfigurationBuilder();
        builder.setOAuthConsumerKey(oAuth_ConsumerKey)
        .setOAuthConsumerSecret(accessTokenSecret);
        builder.setOAuthAccessToken(accessToken);
        builder.setOAuthAccessTokenSecret(accessTokenSecret);

        TwitterFactory twitterFactory = new TwitterFactory(builder.build());
        Twitter twitter = twitterFactory.getInstance();

        try {
            List<twitter4j.Status> statuses;
            String user = "@pagename";

            statuses = twitter.getUserTimeline(user);
            for (int i = 0; i < statuses.size(); i++) {
                twitter4j.Status status = statuses.get(i);
                Log.i("Tweet Count " + (i + 1), status.getText() + "\n\n");
            }
        } catch (TwitterException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return null;
    }

(The above code is being done in the doInBackground method of the AsyncTask. Just thought you should know)

And I am getting an error saying: No authentication challenges found. Relevant discussions can be found on the Internet at: ...

I viewed previous posts and it said to check my date and time. I did that and they are all correct and set to automatic. (Since i have a slow internet connection) I also tried running it on a faster internet connection. I now think that there is something wrong with my code.

I am new to integrating twitter to my android app so explanatory guidance would also be helpful along with the answer.

Thanks...

Twitter4j adapts singletone and it maintains its login/authentication status and raises exceptions everytime you try to login/authenticate

What you have to do is separate the authentication login from the rest of API calls. in your case you need something like this:

private Twitter mTwitter;
private void login(String[] credentials){
  String oAuth_ConsumerKey = credentials[0];
    String  oAuth_ConsumerSecret = credentials[1];
   String   accessToken = credentials[2];
   String   accessTokenSecret = credentials[3];

    System.out.println("Credentials -------- " + oAuth_ConsumerKey
            + "\n" + oAuth_ConsumerSecret + "\n" + accessToken + "\n"
            + accessTokenSecret);

    ConfigurationBuilder builder = new ConfigurationBuilder();
    builder.setOAuthConsumerKey(oAuth_ConsumerKey)
    .setOAuthConsumerSecret(accessTokenSecret);
    builder.setOAuthAccessToken(accessToken);
    builder.setOAuthAccessTokenSecret(accessTokenSecret);

    TwitterFactory twitterFactory = new TwitterFactory(builder.build());
    mTwitter = twitterFactory.getInstance();
}

 private List<Status> getTimeLine(){

   List<twitter4j.Status> statuses = null;
    try {

        String user = "@pagename";

        statuses = mTwitter.getUserTimeline(user);
        for (int i = 0; i < statuses.size(); i++) {
            twitter4j.Status status = statuses.get(i);
            Log.i("Tweet Count " + (i + 1), status.getText() + "\n\n");
        }

    } catch (TwitterException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
   return statuses;

}

Make sure you call both methods from background thread and call login once every run.
