This class was deprecated
in API level 26.
ProgressDialog
is a modal dialog, which prevents the
user from interacting with the app. Instead of using this class, you should
use a progress indicator like ProgressBar
, which can
be embedded in your app's UI. Alternatively, you can use a
notification
to inform the user of the task's progress.
A dialog showing a progress indicator and an optional text message or view. Only a text message or a view can be used at the same time.
The dialog can be made cancelable on back key press.
The progress range is 0 to max
.
