What does "it's not working" mean? Is the HTTP request being sent as you want it to be sent? Is the server receiving all data correctly? If so, does it return all data as it should? And finally, what is the response received on the device?
Also, if you want to send a POST, why are you using HttpGet?
(As an aside, and as I told you before in the other thread
where you asked about this, there's nothing at all Android-specific about this.)
