getting Status from Twitter using twitter4j on Android

Question

I am trying to retrieve status with Twitter4j, but I get a Unfortunately TestProject has stopped error and my app closes. I am also not getting anything in logcat so I do not know where to start troubleshooting.

This is the method executed when a button is pressed, I am basically making an instance of the class which contains all the oAuth setup and the call to the twitter API for the status. I know this should probably be done with an Async call since it deals with network, but for now I just wanted to retrieve a status even if the UI is blocked:

    public void onGetStatus(View v){

    if(v.getId()==R.id.button1){



        GetUserStatus status = new GetUserStatus();
        ResponseList<Status> a = status.twitterSettings();

        for(Status s: a){
        editText.setText(s.getText());

        }

    }

}

This is the class with all the twitter configurations for my account.

public class GetUserStatus {



public ResponseList<Status> twitterSettings(){

  ConfigurationBuilder cb = new ConfigurationBuilder();
  cb.setDebugEnabled(true);
  cb.setOAuthConsumerKey("xxxxxx");
  cb.setOAuthConsumerSecret("xxxx");
  cb.setOAuthAccessToken("xxxxx");
  cb.setOAuthAccessTokenSecret("xxxx");



TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = tf.getInstance();


try {
    ResponseList<Status> a = twitter.getUserTimeline(new Paging(1,5));

    return  a;


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


}
return null;





}

}

Research I have done

I have been mostly going off twitter4j's website code examples and it seems everything is up to date so I dont think twitter4j is deprecated. I have also looked through other twitter4j questions on StackOverflow.com but most deal with 404 error or some other type of error, while I am not getting any errors.

Answer 1

The issue was StrictMode.ThreadPolicy was introduced since API Level 9 and the default thread policy had been changed since API Level 11, which in short, does not allow network operation

(eg: HttpClient and HttpUrlConnection) get executed on UI thread. If you do this, you get NetworkOnMainThreadException.

Using AsyncTask fixed the issue. I added a nested class within my activity

class GetUserStatus extends AsyncTask < Void, Void, ResponseList < twitter4j.Status >> {

        @
        Override
        protected ResponseList < twitter4j.Status > doInBackground(Void...params) {


            ConfigurationBuilder cb = new ConfigurationBuilder();
            cb.setDebugEnabled(true);
            cb.setOAuthConsumerKey("XXXX");
            cb.setOAuthConsumerSecret("XXXXX");
            cb.setOAuthAccessToken("XXXXX");
            cb.setOAuthAccessTokenSecret("XXXXXXX");




            TwitterFactory tf = new TwitterFactory(cb.build());
            Twitter twitter = tf.getInstance();



            try {
                ResponseList < twitter4j.Status > a = twitter.getUserTimeline(new Paging(1, 5));


                return a;

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




            return null;
        }


        protected void onPostExecute(ResponseList < twitter4j.Status > stats) {

            for (twitter4j.Status a: stats) {

                editText.setText(a.getText());



            }

        }




    }

The other issue I was having with logcat not displaying exceptions, was because Eclipse automatically selected a filter, when I chose the option "all messages (no filter)" I was able to see the stack trace.
