Always report progress accurately. Don’t display inaccurate progress information just to make your app appear busy. Only use progress bars for tasks that are quantifiable. Otherwise, use an activity indicator.
Use progress bars for tasks with a well-defined duration. Progress bars are great for showing the status of a task, especially when it helps convey how much longer the task needs to complete.
Hide the unfilled portion of track in navigation bars and toolbars. By default, a progress bar’s track includes both filled and unfilled portions. When used in a navigation bar or toolbar, such as to denote a page loading, a progress bar should be configured to hide the unfilled portion of the track.
Consider customizing a progress bar’s appearance to match your app. A progress bar’s appearance can be adjusted to match your app’s design. You can specify, for example, a custom color for both the track and fill.
