Final answer:
A pending intent is an Android development concept that lets other apps execute an intent later, often used for scheduling actions like alarms.
Step-by-step explanation:
A pending intent is an intent that can be passed to other apps so that they can execute the intent at a later time. In the context of Android application development, a pending intent allows you to grant permission to another application to perform an action defined by an intent, on behalf of your application, at a later point in time. This is particularly useful for tasks such as setting up alarms, where you want an action to occur at a predetermined time, regardless of whether your application is currently running.
