Activity indicators and progress indicators

Activity indicators and progress indicators show users that their BlackBerry® PlayBook™ tablet is performing an action, such as searching for items or connecting to a Wi-Fi® network. Users cannot interact with these indicators.

If you can determine the duration of an action, use a progress indicator.

If you want to show that your application is working but you cannot determine the duration of the action, use an activity indicator.

Best practices

  • Always indicate progress when an action takes more than 2 seconds to complete.
  • Provide useful progress information. For example, if users are downloading an application, indicate the percentage of data that has been downloaded. Be as accurate as possible with the progress information.
  • For progress indicators, use concise, descriptive text to indicate what the action is (for example, "Loading data" or "Building an application list"). If an action takes a long time and you want to communicate what is happening at each stage, provide text that describes each stage (for example, "Downloading" or "Installing").
  • Use sentence case capitalization. Capitalize the first word and any other word that requires capitalization (such as a proper noun).
