I wouldn't hash it on client side. If any of the value is missing due to a bug and then upgrade would address this, your hash will potentially mismatch causing some problems. I'd rather store all the values on server side and apply some logic to cope with the above scenario (which is easily doable as I'd knew that some values were missing and now are present, which is not doable if you get just result hash) -- Regards, Marcin -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
