sending data from one android device to another android device via server

I am developing an application in which I have to send data from one device to another device via server. I am using soapObject for sending the data.

I am able to send data from the device 开发者_开发技巧to server and get back the result from server,but I am not getting how to send data sent from one device to another device via the server.

If anybody knows how to do this, please respond.

Thanks

The other device (the receiving phone) has to establish a connection with the server. When the server receives data from the sending device, it can then send the data directly to the receiving device.
