how to listen for changes in Contact Database
<p>I am trying to listen for any change in the contact database.</p>

<p>So I create my contentObserver which is a child class of ContentObserver:</p>

<pre><code> private class MyContentObserver extends ContentObserver {

        public MyContentObserver() {
            super(null);
        }

        @Override
        public void onChange(boolean selfChange) {
            super.onChange(selfChange);
            System.out.println (" Calling onChange" );
        }

    }

MyContentObserver contentObserver = new MyContentObserver();
context.getContentResolver().registerContentObserver (People.CONTENT_URI, true, contentObserver);
</code></pre>

<p>But When I use 'EditContactActivity' to change the contact database, My onChange function does not get called.</p>
