Question

I am a beginner to android and have designed a login GUI for app where a user will enter the login details. After fetching login details in java code (in strings) how can I pass it to server to check for a valid combination? Also when a new user enter registration details how can I pass it to server and store it in DB (MySQL DB)? What is the purpose of web service? Should I use web service or servlets (this is not the only thing later in my app I need to send contact details to/from server)?
I’ve read about SOAP and REST web services which one should I prefer? I would like to code in java for everything. Should (or can) I use Google AppEngine for server part? Am I supposed to create XML file of login details to send it to web service in case I use it?
A sample code could be of great help…
Thanks in advance.

Web Services are used for passing and performing operations in databases of remote servers. You can use JSON type for parsing data & sending data to server.
