NPE when purchasing already owned item #113

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
STEPS TO REPRODUCE:

1. call IabHelper.launchPurchaseFlow() for already owned item.

ACTUAL OUTPUT:

Application crashes somewhere inside launchPurchaseFlow(Activity act, String 
sku, String itemType, int requestCode, OnIabPurchaseFinishedListener listener, 
String extraData).

I can't figure out exact place, cause stack-trace points to non-sense -
IabHelper.java:333 where simply function call is made, no access that could 
cause NPE.
I suspect it's because I'm using ProGuard.

NOTES:
I've found a way to workaround this issue. (Don't know how to do the .patch 
file, so try to explain here)

It seems that "else" clause is missing inside "try" block of the 
"launchPurchaseFlow" method.
All code after if-block (response != BILLING_RESPONSE_RESULT_OK) should be 
placed into "else" block.

Also in "catch" clauses one should call flagEndAsync().

Hope that helps somebody.
