At the start of your program, do
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
Then when you want to display a rotating little circle in the title
bar, do
setProgressBarIndeterminateVisibility(true);
When updating or whatever is done, do
setProgressBarIndeterminateVisibility(false);
Of course, you can use other types of progress bars in pretty much the
same way.
