twitter4j error when search twitter

Question

[EDIT] I am trying to search some tweets from twitter using twitter4j version 4.0.4 as library. This is my method

public void processAll(View view){
    Log.d("click","OKE");
    ConfigurationBuilder cb = new ConfigurationBuilder();
    cb.setDebugEnabled(true)
            .setOAuthConsumerKey("xxxxx")
            .setOAuthConsumerSecret("xxxx")
            .setOAuthAccessToken("7xxxxL")
            .setOAuthAccessTokenSecret("xxxxx");
    TwitterFactory tf = new TwitterFactory(cb.build());
    Twitter twitter = tf.getInstance();
    Log.d("connected","OKE");

    try {
        Query query = new Query("handsome");
        Log.d("TEST","OKE");
        QueryResult result = twitter.search(query);
        List<Status> tweets = result.getTweets();
        for (Status tweet : tweets) {
            Log.d("RESULT","@" + tweet.getUser().getScreenName() + " - " + tweet.getText());
        }
    }
    catch (TwitterException te) {
        te.printStackTrace();
        Log.d("RESULT","Failed to search tweets: " + te.getMessage());
        return;
    }

}

But my app stopped when this method is called.

 at com.fajarainul.coconut_dev.titikota.SetTimeActivity.processAll(SetTimeActivity.java:68)

references to

    QueryResult result = twitter.search(query);

here my full logcat

Thanks in advance!

Answer 1

You are throwing a NetworkOnMainThreadException which means you are attempting to run network code (i.e. running a search via the twitter API) on the applications main thread.

You will need to move this code into a background thread using something like an AsyncTask (see docs) for it to work.

I would suggest reading the docs and also the responses to the previous question on SO: How to fix android.os.NetworkOnMainThreadException?
