Activity indicators and progress indicators show users that their BlackBerry® devices are performing an action, such as searching for items or removing languages.

Use an activity indicator if you want to show that the BlackBerry® device is working and you cannot determine the duration of the action. You can add an activity indicator to any component, such as a screen, text field, or list item. You can also add text to an activity indicator to describe the action.

Use a progress indicator if you can determine the duration of an action. Progress indicators include a label to indicate what the action is and a horizontal bar that fills from left to right as the action progresses. A percentage appears in the bar to indicate how much of the action is complete.
