The iPhone has this swirling icon, which you can make appear when the Internet is working behind in the background. It's a VERY simple call to turn it on/off.

Does Android have anything like this? How do I call it and how does it work?

  • Most android devices already have a network usage graphic in the status bar which displays when the device is sending\ receiving data. – Wesley Wiser Nov 28 '12 at 04:20

You should display this in the ActionBar.

The simplest way 

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setProgressBarIndeterminateVisibility(true);

Or using ActionBarSherlock for backwards compatibility

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setSupportProgressBarIndeterminateVisibility(true);

No, i haven't seen it on android yet. However with ICS and above, we see 2 arrows accompanying the WiFi or 3G to indicate if there is activity on the network. However it may not be possible to programmatically control it.

You could otherwise use a indeterminate progress bar within your activity to show background work.

You could try using Android Notifications and use an AnimationDrawable. Check this answer. (Note that I haven't tried it).
