How to implement a countdown timer in an Android app.

A CountDownTimer is a class in the Android SDK that is used to implement a countdown timer in an Android app. It counts down from a specified time (in milliseconds) to zero, and can be configured to send updates to a handler at specific intervals (e.g. every second) during the countdown. The CountDownTimer class can be subclassed to customize the behavior of the timer, such as adding custom logic to handle the completion of the countdown.
