One easy method is to install gimp and the gimp animation package. Open the first image, then go to file > open as layers and select the rest of the files for the animation. After that you can go to Filters > Animation > Playback and it will give you a preview.
I don't think you will find any perfect solution since there isn't any solution where it will read the desc.txt and loop the different parts correctly. I suppose you could use an android virtual device from the SDK, but that will be alot to get setup and push the files over.
