Okay, so I followed the instructions in this thread as far as I'm able to tell but I'm getting a FileNotFoundException whenever the 1.5 emulator tries to access a particular image in the drawable directory. I have two drawable directories: "drawable" and "drawable- hdpi-v4". Any idea why this shouldn't work?
