title: Android SyncAdapter Server-side Implementation
body: <p>I have read a lot of tutorials on Sync Adapter such as the tutorial on <a href="http://www.c99.org/2010/01/23/writing-an-android-sync-provider-part-1" rel="nofollow">http://www.c99.org/2010/01/23/writing-an-android-sync-provider-part-1</a> as well as the SampleSyncAdapter sample code on Android Developer website.
  But I don't understand that how the server side handles the Authentication and synchronization queries. Is it possible for me to use php  to query from a mySQL server database? </p>
