If you have access to the save file on your android you could open it on PC and work it out to the latest version.
Optionally just download
CoCEd and recreate your save to transfer back to your android, CoCEd lets you edit pretty much everything, your inventory, progression, appearance, stats, etc... So you should be able to recreate your old save within just a few minutes.
I can't seem to get Load File working either, even though I assume that I have gotten it work in the past, since there are signs of me actually trying it... Trying to figure out stuff.
