Right, it doesn't lag, just crashes. The largest files are the Spriter scon's--heavily compressed in the APK and presumably uncompressed at some point on the device--but they're necessary for the animated sprites. The images are just 7.70mb total and audio only 6.71mb total.
Ok so you did read what I wrote about sprites too large you get black screen. Now what size is your spriter images ? 400x400 ,500x500 ,etc.
Also what file type are the spriter sprites? .png .jpeg?
