I\'m trying to integrate Android Market in-app purchases into my app, but unfortunately coming across an annoying error every time I try to purchase a real inapp product.
This error comes when everything you done is perfect, you have used signed APK with the proper product id, but you have to note that the account that you are using might don't have proper valid credit card details.
So whenever you want to buy any product even with test account, that account should have valid credit details.
