Fix my Java application (should be quick and easy)

Hi Java coders: I bet this will be easy for anyone who's been using Java for a while. I only started a few weeks ago and got to the point I am now. I originally made my application in two parts so I could create it easier (with the intention of putting them together once both portions of the script were working). Both were working PERFECTLY until I tried to add them together (oops!). I just need someone to look at it and fix what I did wrong. The code is up to look at. The part that isn't working right now is after you type in a URL and select 10 (or more) for the Link Crawler is that the threading part of the application doesn't even try to start (from what I can tell). ** THE CODE COMPILES! Please load it and take a look. The app is basically 3 activities 1: the main gui screen that you need to input data into 2: the first thing it does is it parses the URL you input in step 1 and collects links from the page 3: the second thing it does (after it gets the links) is it scrapes another URL to collect more links. This process is done via threads which is probably why I can't get it to work. Please take a look. I just want to make sure the threads WORK and everything runs the way it should. Preference given to those who 1) can get it done today/quickest and 2) those who can tell me they see the problem(s). This is a non profit script I'm writing for myself. This is the very first time I've ever done something in java. ## Deliverables Must load/compile through Eclipse. My main goal is to make this portable to Android in the near future, please don't add anything that will be difficult to convert over to Android.
