Progress Dialog - Android Studio - Kotlin

Progress Dialog in Android Studio using Kotlin

What are Progress Bars?

Progress bars are used to indicate that a task is running in the background, such as downloading files or creating a user account. They help improve user experience by providing visual feedback during long operations. 

In Android, ProgressDialog is a dialog-based component used to display loading or progress status while a task is being processed. This post explains how to implement a simple Progress Dialog in Android Studio using Kotlin.
