Question

What is pendingIntent in android ? and when we should use it ? , I tried to read about it in android documentation, but unfortunately I didn’t get the answer !

Answer 1

A PendingIntent is an Intent action that you want to perform, but at a later time. Think of it a putting an Intent on ice. The reason it’s needed is because an Intent must be created and launched from a valid Context in your application, but there are certain cases where one is not available at the time you want to run the action because you are technically outside the application’s context (the two common examples are launching an Activity from a Notification or a BroadcastReceiver.

By creating a PendingIntent you want to use to launch, say, an Activity while you have the Context to do so (from inside another Activity or Service) you can pass that object around to something external in order for it to launch part of your application on your behalf.
