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.

Kind of Intent which is not called immediately, but after some time like reaction to some action. In other way, you can give your permissions to other application with it.
It is used for example in widgets. When you click button, it performs defined with pending intent.
