@pieeater84- do you have a good internet connection - in case it's trying to connect to the servers and goes before it can warn you.
Next up, do you have a lot of other things running. It takes a lot of memory as well as storage for the game to run well and if it can't access enough it will close.
EDIT - I'm using a Lenovo tablet gifted to me for my second town and it took a while to sort it for the 3 button menu to get to Recent Apps and shut all the old stuff down so I could tap happily.
Lastly you haven't added an SD card and moved the game to that, if you did ( and some Android devices push for it ) it will fail.
