Possibly, but if .apk files are "just" .zip files then diffoscope
should really be able to handle them better.
Could you perhaps provide two .apk files in question, ideally in a
wishlist bug against diffoscope?

locate, detect and ultimately fix non-determinism, not to work-around

If disorderfs ""fixes"" the issue for you, then you at least know the
reason why. What tool, exactly, is creating these files?
