twitter4j not recognizing setRpp or Tweet class

Question

I'm trying to set up a twitter search via processing, using twitter4J. I have the most recent version of processing (2.0) and the most recent version of twitter4j (3.0.3). I'm experiencing an error when I run the code that's pasted below (except I xxx'ed out the twitter specific strings): "The function setRpp(int) does not exist"

I found a similar inquiry in a Processing forum: https://forum.processing.org/topic/twitter4j-for-a-noob

The advice for this thread is: Trying to figure out twitter4J as well, and have encountered similar errors.

You can either switch to an earlier version of twitter4J -- v2.2.5 -- or you'll have to figure out the changes made from twitter4j 2.x.x to 3.x.x.

Try changing "setRpp(1)" to "count(1)".

"Tweet" might not work either -- you can try changing those to "Status".

---

When I switch setRpp > count and Tweet > Status, processing can't seem to find the function, "getFromUser" Error: The function getFromUser() does not exist

I assume that getFromUser is a function of the Tweet class, and because I changed the class from Tweet to Status, processing can no longer find that function.

Has anyone one else experienced these issues? Please let me know, thank you!

It sounds like you have the new twitter4j library. No problem, I'm using the 3.0.3 twitter4j, and it seems things have changed somewhat. That is what I've got working:

TwitterFactory twitterFactory;  

A new public TwitterFactory twitterFactory, and in connectTwitter(), I basically swapped what you had out for this.

ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setOAuthConsumerKey(OAuthConsumerKey);
cb.setOAuthConsumerSecret(OAuthConsumerSecret);
cb.setOAuthAccessToken(AccessToken);
cb.setOAuthAccessTokenSecret(AccessTokenSecret);
twitterFactory = new TwitterFactory(cb.build());
twitter = twitterFactory.getInstance();

To create my Twitter twitter object. I am pretty sure thats all that I've changed, but incase I've missed something, here is a gist https://gist.github.com/loadedsith/5113946

Nice job on your header.

I had this problem too, getFromeUser() is no longer a Status method. Now you need to create a User class, and then get its name with getName(). I did like this:

Status t=(Status) tweets.get(i);
User u=(User) t.getUser();
String user=u.getName();

I hope this helped you.
