How to do a spinning animation while downloading a file
<p>I have a program that copies a file to the sd card.  The program takes a while to run, and now it just freezes while the file is being copied.</p>

<p>I saw some other programs that have a animation of a wheel spinning in the center of the screen while the file is being down loaed.</p>

<p>I tried to google spin control, but this brought up animation about a selector control using spinning wheels.</p>

<p>Is this feature built into the android?</p>
