we are finishing transition from Cocos Creator 1.5.2 (where our game worked for more than a year) to 2.0.9. I think most of the transition is done already.
However, currently our problem is: when we build the app and run it on a mobile phone, after sdkbox.IAP.refresh() is called none of the registered 4 listeners (onRestored, onRestoreComplete, onProductRequestSuccess, onProductRequestFailure) is called and there is this message in the logcat log:
I/IAP: Can’t find any IAP listener. result: 0
Any idea how to solve this? I have been stuck on this problem for several days.
