I tried to include in-app billing in my app and for the purpose of testing, based the whole procedure on the "TrivialDrive" example for version 3 of in-app billing (and implementing the unmodified versions of the IAB files as supplied in the "util" subdirectory of the demo), but it doesn't work for me - on LogCat, just before the app terminates with an error, it gives the message "In-app billing error: Illegal state for operation (launchPurchaseFlow): IAB Helper is not set up." (right after the startRegistered() function has been fired and given me the LOG message "Register button clicked; launching purchase flow for upgrade.")...
Any idea what goes wrong here?
Here are the relevant parts of my code:
