1)uploaded apk file as draft in market

2)created product list and published

3)Registered test account and set that account as a primary account

but when i testing all other reserved product id's working fine,but my product id purchase is not working .buy button is disabled.

but developer site they mentioned that u can simulate the purchasing process so any body can give me the suggestion

Answer 1

You obviously haven't selected the payment method, that's why buy button is disabled,you should choose one option - visa card or something else.
