Why does Android "TrivialDrive v3 Billing Sample" not allow multiple asynchronous calls?
I am using the utilities from Android "TrivialDrive v3 Billing Sample" and like many people I am getting the error:
java.lang.IllegalStateException: Unable to start asynchronous operation (launchPurchaseFlow) because another async operation (launchPurchaseFlow) is in progress.
These approaches don't make sense to me as the former requires me to implement retry mechanisms / errors in my application, and the latter tinkers with this library thread (you might as well remove that "").
My question is , what is the reason for the "1 asynchronous operation at a time" limitation in IabHelper?
If there is a real reason, then perhaps each method should throw an error that will force the developer to turn to it. If it doesn't, I think removing the "throwing illegal state ..." code should be removed.
