Looks like this is a bug in Google Play game services ImageManager.
We were using ImageManager loadImage() to load images for unlocked achievements. Because the class causing the exception is in the ImageManager package android.gms.common.images we tried updating the app to stop using ImageManager (switched to using APK image files). The bug has stopped, so I guess that's the cause On Monday, July 15, 2013 7:23:58 AM UTC-7, mwk888 wrote: > > HELP: we are getting this error in large numbers from customers since > releasing an update which adds Google Play services achievements to our > game.
