Android - what does requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS) do?

Question

Pretty much in in the title.

Have seen this around and after a bit of searching can't seem to find out what it actually does or what indeterminate progress is.

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS)

It's used for example by RoboSpice samples.

Update: Currently this feature is deprecated and not supported on current devices, check the official documentation.

Original answer:

Simply rotating circle in top right corner in Actionbar which represent some background action.
