I making an online games download website for mobile.. I want to have a functionality wherein when a user downloads a game (possible a jad or jar file)
once the download is finished, the server should know about it so that only after a successful download the user should be charged . Is it possible to do so?
or should i start the billing process once the user starts to download.. the reason behind this is that if while downloading a user gets disconnected from the internet due to some problem .. and the user is already charged then that would be unfair on our part..
Can any one suggest how should i go about it?? can someone send me a sample code or tutorial regarding this.Please help me out its really urgent..
