Well XML is a universal language, so if you are working with that then you need not get too consumed in the fact it is coming from an Android device. You mentioned the following:
i wants to write a web application in vb.net which receive the request from android application for login purpuse in xml
Well if you are writing .NET code, then you just need to parse the XML received using either LINQ to XML (my recommendation) or XPath (older way). If you have an .XSD for the XML then this makes reading the XML even easier.
On the other side, you can build back up the XML response and send it back in whatever method required (web service, etc). As I see it it is a matter of reading and writing XML rather than anything specific to Android development. If this is the case you
can focus on the parsing and creation of the XML to send and receive.
Have a look to the following for more information:
