Hi All,
public static void main(String[] args) {
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true);
cb.setOAuthConsumerKey("xxxxxx");
cb.setOAuthConsumerSecret("xxxx");
cb.setOAuthAccessToken("xxxx");
b.setOAuthAccessTokenSecret("xxxxxxx");
TwitterStream twitterStream = new TwitterStreamFactory(cb.build()).getInstance();
StatusListener listener = new StatusListener() {
@Override
public void onException(Exception arg0) {
// TODO Auto-generated method stub
}
@Override
public void onDeletionNotice(StatusDeletionNotice arg0) {
// TODO Auto-generated method stub
}
@Override
public void onScrubGeo(long arg0, long arg1) {
// TODO Auto-generated method stub
}
@Override
public void onStatus(Status status) {
User user = status.getUser();
// gets Username
String username = status.getUser().getScreenName();
System.out.println(username);
String profileLocation = user.getLocation();
System.out.println(profileLocation);
long tweetId = status.getId();
System.out.println(tweetId);
String content = status.getText();
System.out.println(content +"\n");
GeoLocation geolocation = status.getGeoLocation();
System.out.println(geolocation +"\n");
}
@Override
public void onTrackLimitationNotice(int arg0) {
// TODO Auto-generated method stub
System.out.println("onTrackLimitationNotice" +"\n");

}
};
FilterQuery fq = new FilterQuery();
double lat = 53.186288;
double longitude = -8.043709;
double lat1 = lat - 4;
double longitude1 = longitude - 8;
double lat2 = lat + 4;
double longitude2 = longitude + 8;
twitterStream.addListener(listener);
double[][] bb= {{lat1,longitude1}, {lat2 ,longitude2}};
// fq.track(keywords);
fq.locations(bb);
twitterStream.filter(fq);
}
This code is to collect tweets in the general UK & Ireland location but doesn't collect tweets or sometimes (rarely) collects tweets from areas outside the bounding box.
If i widen the bounding box I do get tweets but again sometimes they are outside the bounding box.
I am working from the logic that the 1st point of the bounding box is SW corner and next point is NE corner.
Any ideas what could be the problem? I am using Twitter4j 3.0.3
Thanks,
David
I think you are sending the coordinates in the wrong order. According to Filter Spec, Twitter expects a comma-separated list of longitude,latitude, but you are sending (latitude,longitude) pairs.
The correct version should be:
double lat = 53.186288;
double longitude = -8.043709;
double lat1 = lat - 4;
double longitude1 = longitude - 8;
double lat2 = lat + 4;
double longitude2 = longitude + 8;
double[][] bb = {{longitude1, lat1}, {longitude2, lat2}};
FilterQuery fq = new FilterQuery();
fq.locations(bb);
twitterStream.filter(fq);
