Android Google Play Services error: didn't find class com.google.android.gms.maps.mapfragment on path dexpathlist

Question

I know this issue gets reported pretty frequently, and the simple, oft-recommended solution is to check how I'm referencing the google play services library. However, I'm pretty confident that I've got all my bases covered. I've literally lost sleep over this error, so any advice is certainly appreciated. Thanks in advance.

First, here's my stack trace:
