Contentobserver Not Working In Android

Hi I am trying with the below code.The content resolver is not working with this.Can anyone give an idea getContentResolver().registerContentObserver(MyContentProvider.CONTENT_URI,

Solution 1:

A ContentObserver only works with a ContentProvider that calls one of the notifyChange() methods on a ContentResolver when the contents of the provider change. If the ContentProvider does not call notifyChange(), the ContentObserver will not be notified about changes.

Solution 2:

Problem

The problem I experienced was that the ContentObserver.onChange() method never got called because the ContentObserver's Handler's Looper was initialized improperly. I forgot to call Looper.loop() after calling Looper.prepare()...this lead to the Looper not consuming events and invoking ContentObserver.onChange().

Solution

The solution is to properly create and initialize a Handler and Looper for the ContentObserver:

// creates and starts a new thread set up as a looper
HandlerThread thread = newHandlerThread("MyHandlerThread");
thread.start();

// creates the handler using the passed looper
Handler handler = newHandler(thread.getLooper());

// creates the content observer which handles onChange on a worker thread
ContentObserver observer = newMyContentObserver(handler);

useful SO post about controlling which thread ContentObserver.onChange() is executed on.
