Android Alarm Manager is a utility for scheduling time-based operations in Android apps. It lets you set triggers to execute code at specific times, even if the app is not running. You create an `AlarmManager` instance, configure an `Intent` with the desired operation, and schedule it using methods like `setExact()` for exact timing or `setInexactRepeating()` for periodic tasks. This tool is essential for tasks such as reminders, updates, and background services, ensuring timely and efficient app functionality.
