Hey, I'm sorry you can't progress the game.
I asked dev team to play through android and see if it crashes for anyone, and nobody did.
I really have no idea what could cause it.
I do have suggestion:
Clean the memory cache on your phone and turn off any background apps when playing.
if that doesn't help I will be looking into fix but I won't be able to release it anytime soon.
I hope it will work! good luck.
