i wanted to use UIL for one of my projects so i just made this prototype project to see how the library works. I built it according to the sample project from https://github.com/nostra13/Android-Universal-Image-Loader. But when i run the proj the images are not shown and the logcat doesn't show any errors as well. I just get a blank white screen with project name in the title bar.Can anybody tell me whats wrong in my code.Any help is gratefully accepted.
