Hello there,
I am quite new to this so please bear with me. I am trying to use a keyword search to pull images from twitter using twitter4j. I want it to show the images positioned randomly on the screen in a loop.
This code I have below is a combination of different ones I have found online. Its currently finding tweets using these keywords and showing them in the console, however, it is not displaying them on the screen and I’m not sure why…
Another thing is that I think it is doing a live stream from twitter so pulling tweets immediately at the time the code is run, so I am not getting lots of results when I put in an obscure keyword, I want it to search for the last 100 tweets with images using the keywords.
From another project I’ve worked on I know a query search gave me way more results but I’ve tried to apply that here with no success 
Query query = new Query("#SudaneseCulture");
query.setCount(100);
I’d really appreciate all the help I can get! thank you
