When should you use PendingIntent in Android development?

In Android development, a PendingIntent is used when you want to grant another application (or even your own application) the ability to perform a predefined action on your behalf at a later time, often in response to some event or user action. Some common scenarios where you might use a PendingIntent include:

• Notifications: To launch an activity or a service when the user taps on a notification.
• Alarms: To set an alarm that triggers a specific action in your application.
• Broadcasts: To send broadcasts to other applications when specific conditions are met.
