Using In App Purchase on Android

corona version ? 755
source code? corona Simple Code/network/InAppPurchase and I change the googleProductList to myown productList.

I built an apk package, and then upload to google play.
however, when i press the upload button google play return a error:“An unexpected error occurred, please try again later” immediately.

Why I can’t upload my apk to google play and what should I do?

Thanks very much!!! [import]uid: 82934 topic_id: 26498 reply_id: 326498[/import]
