  1. How to fetch or retrieve data from server and post updates on android application

    use HTTPClient.

  2. How to manage offline storage means whenever there is no internet connection how the data gone be updated on android application

    I think you don't understand what offline storage means. If there is no internet connection, that's it. You are not able to update your content. Offline storage is useful if you have internet connection, but not everytime. The content you downloaded when you had internet connection can be saved to SQLLite to be loaded when you don't have internet connection.

    Create WebService as an interface. Do not let other system to be able to directly access your files. Or just create a PHP files that basically return Json or XML Data. Other option : create an RSS.

  4. More about the topics : if i want to syncronise the update with website , how do i handle it or implement it ? i am not asking any sort of coding here .

    Create an event to start sync using HTTPClient. If there is new update, save it to SQLLite(for offline storage) and display the content. The event can be triggered during the start of your application or clicking refresh button and if Internet exist.

Update :

There is a new framework called couchbase mobile. You can sync the local mobile db from a couch server. You can insert/update the data locally(offline mode) and then the data can be synced also to the couch server, whenever you have internet connection. This means the need to create HTTPClient is no longer necessary.

For the database, try cloudant.
