NumberFormatException occuring on startup

[T-Spoon]

It seems like recently we've been getting NumberFormatException errors when starting the app and initializing AndroidRate. I'll need to do further investigation but here's an (obfuscated) stack trace in case someone else bumps into this:

Clearing the app data appears to fix it - I assume some dodgy value is being stored by AppRate and re-parsing it causes a crash.

This issue popped up again so thought I'd revisit my old issue!
