Hi Everybody!

Im new to processing and im trying to get a piece of code i found here to work. I've imported the library, changed the quotations but it is saying the fuction getOAuthAuthorizedInstance (String, String, AccessToken) does not exist.

From what I've read this is a problem with the setup but being new i don't know what to do... here is my code.

I found this here

Error Messages

The function XXXX does not exist.

Processing has found something that it thinks is a function, but it can't find a match. Either the function has the wrong name or the wrong number and type of parameters.

What is the function name?

What would the proper function name be?

Do i need to add a function into the setup?

If you would like to help I have another post on the arduino forum that might help you get to where im at.

Thanks for your help

Hi,

Hope you have found a solution for this by now but if not - this code from http://robotgrrl.com/blog/2011/02/21/simple-processing-twitter/ is great for editing down to the relevant bits.

What part of your code is the error? Does it let you know what function name can't be found?

Try substituting this under line 45 :

Twitter twitter = new TwitterFactory().getInstance();

twitter.setOAuthConsumer(consumer_key, consumer_secret);

token = new AccessToken(oauth_token, oauth_token_secret);

twitter.setOAuthAccessToken(token);

and in your setup try adding in under line 31 :

AccessToken token;

Let me know if you have any luck?

Cheers, Martin

I have the same problem too and I have added your code mskelly, and it finally ran. However, this was the error message that I had when I clicked my mouse on the applet..
