Twitter4j - finding users by geolocation

diegozaks

Hi everyone, I'm working on a sketch in which I need to find a random user from a specific location and @mention them in a tweet.

-So far I have not been able to do it, mostly because I'm just not an experienced coder and have never dealt with the twitter API before. -But this is the frankestein's monster code what I'm trying:-

I've made some progress, please look at comment below.

I appreciate any help! Thanks in advance!

Here is my new version: import twitter4j.conf.*; import twitter4j.*; import twitter4j.auth.*; import twitter4j.api.*; import java.util.*;

//package twitter4j.examples.search;

String ConsumerKey = "mykey";
String ConsumerSecret = "mykey";
String oauth_token = "mykey";
String oauth_token_secret = "mykey";

TwitterFactory tf;

String geoURL;
double lat;
double lon;
double res;
String resUnit;

List<Status> tweets;

import java.util.List;

void setup() {
  println("setup");
  println();
  geoURL = "http://search.twitter.com/search.json?geocode=";
  println("geoURL" + geoURL);
  println();
  ConfigurationBuilder cb = new ConfigurationBuilder(); //ConfigurationBuilder declared cb is a new instance of this
  cb.setDebugEnabled(true) 
    .setOAuthConsumerKey(ConsumerKey) //sets the Consumer Key String
      .setOAuthConsumerSecret(ConsumerSecret) //sets the Consumer Secret String
        .setOAuthAccessToken(oauth_token)
          .setOAuthAccessTokenSecret(oauth_token_secret);
  tf = new TwitterFactory(cb.build());
}

void draw() {

  println("void draw");
  println();
  Twitter twitter = tf.getInstance();

  lat = 10.5000;
  lon = 66.9167;
  res = 10;
  resUnit="mi";



  try {
    QueryResult result = twitter.search(new Query().geoCode(new GeoLocation(lat, lon), res, resUnit));
    //println(result);

    // printing my tweets
    List <Status> tweets = result.getTweets();
    println("tweets: " + tweets);



    exit();
  }  

  catch (TwitterException te) {
    te.printStackTrace();
    println("Failed to search tweets: " + te.getMessage());
    exit();
  }
}

I've managed to get 15 tweets with all their info from the required location. Now all that I'm missing is a way to isolate and select a screenName from the List. Suggestions?

I now have working code that does the first part of what I want. Query twitter and return a single random user name based on geoLocation.

Here's my code for future reference:

import twitter4j.conf.*;
import twitter4j.*;
import twitter4j.auth.*;
import twitter4j.api.*;
import java.util.*;

//package twitter4j.examples.search;

String ConsumerKey = "*********************";
String ConsumerSecret = "*********************";
String oauth_token = "*********************";
String oauth_token_secret = "*********************";

TwitterFactory tf;

String geoURL;
double lat;
double lon;
double res;
String resUnit;

List<Status> tweets;

import java.util.List;

void setup() {
  println("setup");
  println();
  geoURL = "http://search.twitter.com/search.json?geocode=";
  println("geoURL" + geoURL);
  println();
  ConfigurationBuilder cb = new ConfigurationBuilder(); //ConfigurationBuilder declared cb is a new instance of this
  cb.setDebugEnabled(true) 
    .setOAuthConsumerKey(ConsumerKey) //sets the Consumer Key String
      .setOAuthConsumerSecret(ConsumerSecret) //sets the Consumer Secret String
        .setOAuthAccessToken(oauth_token)
          .setOAuthAccessTokenSecret(oauth_token_secret);
  tf = new TwitterFactory(cb.build());
}

void draw() {

  println("void draw");
  println();
  Twitter twitter = tf.getInstance();

  lat = 10.5000;
  lon = 66.9167;
  res = 10;
  resUnit="mi";



  try {
    // Send a geoLocation query to Twitter
    QueryResult result = twitter.search(new Query().geoCode(new GeoLocation(lat, lon), res, resUnit));
    //println(result);

    // Get my Tweets
    List <Status> tweets = result.getTweets();
    // Pick a random tweet
    int randomTweet = round(random(0, 14));
    Status status = tweets.get(randomTweet);

    String twitterUser = status.getUser().getScreenName();
    println(twitterUser);


    exit();
  }  

  catch (TwitterException te) {
    te.printStackTrace();
    println("Failed to search tweets: " + te.getMessage());
    exit();
  }
}

So after looking into this, it turns out this code will only return the latest tweets from the location and print the usernames, so if a user tweeted more than once that user will be duplicated in the results. I really need help with this, it's been a lot of work and I just can't figure this out.

void getTwitterUser() {
  try {
    int tweetCount = 100;
    // Send a geoLocation query to Twitter
    //ResponseList result = twitter.searchUsers("caracas", 5);
    QueryResult result = twitter.search(new Query().geoCode(new GeoLocation(lat, lon), res, resUnit).count(tweetCount));

    // Get my Tweets
   List <Status> tweets = result.getTweets();


    for (int i = 0; i < tweetCount; i++) {
      Status status = tweets.get(i);

      twitterUser = status.getUser().getScreenName();

      println(twitterUser +" " + i);
    }
  }  

  catch (TwitterException te) {
    te.printStackTrace();
    println("Failed to search tweets: " + te.getMessage());
  }
}

I found the .searchUsers() function, not sure how to create a query for it properly.

Any help is greatly appreciated
