What are the uses of the progressdialog in Android?

ProgressDialog is a dialog box in Android used to display the progress of a task. It is mainly used for the following purposes:

1. Displaying the loading progress of tasks: When an application needs to load data or perform a long-running task, a ProgressDialog can show the progress of the task, giving users a visual feedback.
2. Prevent user actions: Sometimes it is necessary to prevent user actions while performing a task. ProgressDialog can display a modal dialog during task execution to prevent the user from performing other actions until the task is complete.
3. Notify users to wait: When an application needs to perform some time-consuming tasks, a ProgressDialog can display a waiting animation to inform users that the operation is in progress and ask them to be patient.
4. Displaying the success or failure of a task: Once the task is completed, the ProgressDialog can show the success or failure message of the task and provide appropriate feedback to the user.

It’s important to note that ProgressDialog has been deprecated in Android API Level 26, and it is recommended to use ProgressBar and AlertDialog instead.
