Great stuff from Carl. I "think" I am seeing a similar thing, though my app is crashing via:

java.lang.IllegalStateException: IabHelper was disposed of, so it cannot be used.

And it my case, rotating the device one way, then immediately back to the original orientation SOMETIMES causes this crash. Seems that there's a "window" of time where this crash "might" happen (due to the asynchronous nature of IAB like Carl explained).

My fix

My "fix" was to make mHelper static, and only instantiate it if (mHelper == null), and NOT destroy it in the activity's onDestroy() method. This way, once it's setup, it sticks around, and there's no need to worry about asynchronous operations (causes by device orientation) anymore.

Not sure if this is the right fix or not, but thought I'd mention it in case it help others.
