Solved: FUCK ME! I figured it out. the folder i was using to test on my netbook (which existed) didn't exist on my desktop. So i was getting a null error and therefore the program was crashing before main was executed. Really a frustrating thing but i fixed it and decided to leave it up for other people to laugh at me. Also posted the rest of the code incase someone wants to see how to download an image from google.
Ok so i developed an app on my netbook and transferred the project to my desktop. The app worked perfect on netbook. When i try to run the code on my desktop, i get an error saying main class not found. I checked the classpath and it is pointing to the correct class to look for main in and main is declared.
I figured i would just create a new project and c/p the source. did a test with the new project and just ran a simple println (and it worked) but as soon as i imported the source, it again said main class not found. Everything is properly named / setup.
edit: this is my source code.
