title: Android client-server model
body: <p>I'm implementing a client-server model for an online store. Basically I need to retrieve from the server some information like the things the buyer brought (price, description,link, self &amp; other users comments about the article etc) showing it in the device, allowing to navigate thought the catalog, and comment resending the updating info to the server.
  How can I implement that? I have thought in a web server with php+mysql for the server, querying through html post and generating the php answer as a xml with all the information needed.
  Is an acceptable solution?
  I really dont know how many potential user can this application have simultaneous but it could become pretty high.</p>
  
  <p>Thanks in advance</p>
