Answer 1

First thing that I saw was that you tested on emulator the in app purchase:

LINK: Here you will find the following:

"After implementing the above changes, compile and run the application on a physical Android device (Google Play Billing cannot be tested within an emulator session) and make sure that the “In-app Billing is set up OK” message appears in the LogCat output panel. "

And at this LINK

Don't

1)Don't use emulator for testing its does not support Billing Services.

2)Don't use unsigned apk for Billing services.

3)Don't share your key with any one.
