Twitter4j v 2.2.x experience?

in Contributed Library Questions • 2 years ago

Has anyone successfully used the latest Twitter4j library? I am able to authenticate using 2.1.7 but in the move to 2.2.2 I am running into issues.

This is the code that used to work (and currently works with v2.1.7):

Twitter myTwitter;

void setup() {

myTwitter = new Twitter("username", "password");

When using v2.2.2, that code now throws an error saying:

"Cannot instantiate the type Twitter"

Got it working. I started with the write up here: http://tinkerlondon.com/now/2010/09/14/oauth-twitter-and-processing/ . I found I had to modify the code in the write up to work for Twitter4J v2.2.2. Main change was to use the ConfigurationBuilder class.

You'll need to set up a new client side application with read/write permissions here: https://dev.twitter.com/apps/new

This is the code I used to authenticate via OAuth and create a simple hello world app.

import twitter4j.conf.*;
import twitter4j.internal.async.*;
import twitter4j.internal.org.json.*;
import twitter4j.internal.logging.*;
import twitter4j.json.*;
import twitter4j.internal.util.*;
import twitter4j.management.*;
import twitter4j.auth.*;
import twitter4j.api.*;
import twitter4j.util.*;
import twitter4j.internal.http.*;
import twitter4j.*;
import twitter4j.internal.json.*;
String ConsumerKey = " *************************************************************";
String ConsumerSecret = " *************************************************************";
String oauth_token = "**********************************************************************";
String oauth_token_secret = "*************************************************************";
String msg = "Test post via P55 T4J";
boolean sent;
TwitterFactory tf;
void setup() {
size(200,200);
background(255);
sent = false;
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey(ConsumerKey)
.setOAuthConsumerSecret(ConsumerSecret)
.setOAuthAccessToken(oauth_token)
.setOAuthAccessTokenSecret(oauth_token_secret);
tf = new TwitterFactory(cb.build());
}
void draw() {
if(sent) background(100);
}
void mousePressed() {
Twitter twitter = tf.getInstance();
try {
Status st = twitter.updateStatus(msg + " " + getDateTime());
println("Successfully updated the status to [" + st.getText() + "].");
sent = true;
}
catch (TwitterException e) {
println(e.getStatusCode());
}
}
String getDateTime() {
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd-HH-mm-ss");
Date date = new Date();
return dateFormat.format(date);
}

Glad it is helpful Matt.

You might also want to check out the source code examples at 140dev.com ( http://140dev.com/free-twitter-api-source-code-library/). I've been using it for a couple days and it is a great way to aggregate twitter data around specific keywords and parse/store them in a MySQL db before using in your Processing sketches.

was having trouble with directory structure and i got it going in windows as follows:

processing\modes\java\libraries\twitter4j\library (copy jars from latest 2.2.x release here, twitter4j-2.2.x.zip\lib\*.jar) and rename twitter4j-2.2.x.jar to twitter4j.jar

boom, done.

ty for the thread.
