How to display a "loading..." dialog?
<p>I would just like to display something like a dialog (but dialogs are modal only, right?)</p>

<p>when my activity is loading data in onCreate()</p>

<p>and to dismiss this "dialog" when complete.</p>

<p>Just to inform the user that data is loading.</p>

<p>How can I do this easily?</p>

<p><em>I do not want the user to be able to interact with the UI during this period.. just for him to sit and wait until data is loaded.</em></p>
