[android-developers] Re: LVL - Checking licence validity from a server

For anyone else having this problem, the issue was with the response
data.

Signed data comes in looking like this if it's a TEST EMAIL account:-
0|136040138|com.foo.bar|1|ANlOHQOShF3uJUwv3Ql+fbsgEG9FD35Hag==|
123456789012

if it is a genuine MARKET account
0|136040138|com.foo.bar|1|ANlOHQOShF3uJUwv3Ql+fbsgEG9FD35Hag==|
123456789012:GR=10&VT=0987654321&GT=1234567890

When the signed data is validated, the data after the ':' is stripped,
so trying to re-validate the data will fail in the case of the market
account, and pass in the case of the test email account.
