What are Progress Bars?

The Progress bars are used to show the progress of some ongoing task for example if you are downloading some file(s) from the internet you can display the progress bar while the file is being downloaded. Another example could be that when you are creating an account you can show progress bar while the account is being created.

In Android, there is a class named ProgressDialog that is a type of dialog and allows you to show progress while doing some task(s).
