What is the concept of pending intent? Why and when do we use Waiting for Intent?

Question

My question is simple. What is the concept of pending intent? Why and when do we use pending intentions? Please also give an example code.

Answer 1

A PendingIntent itself is simply a reference to a token maintained by a system that describes the source data used to receive it. This means that even if his own application process is killed, the PendingIntent itself will remain suitable for other processes that were provided to it.
