Investigating the problem I founded something more...
The HTTP post generated from the Tablet devices lacks the email address, this is really boring,
specially when you think that the transaction id sent in the HTTP post does not meet the receipt ID that the customer have.
With all this problems you don't have any way to track if a user bought your software or not from your database.
The only way to see if the user bought the software is to see if the device id is present in the database but here there is another problem.
I noticed that the device id sent in the HTTP post is correct but it lacks the initial zeros.
When I check the device id from my app I get something like this:
0000000000134385697345
when I get the Device ID from the HTTP Post I get something like this:
134385697345
this obviously creates problem when generating the correct activation code because the strings are different.
Should I manually truncate the initial zeros when detecting the device id inside my apps before generating an activation code?
So bad.
