Intent :
----------
Think of intent as a message to communicate an action. It is a description of what you want done, example: VIEW VIDEO, PLAY GAME etc.
They are commands which when called would act as communicators between the three core components of Android, i.e. Activities, Services and Broadcast Receivers.
While you are interacting with one activity, you might want to switch to another one; this is done by defining a proper Intent for the action. Here one Activity uses Intent to request the launch of another Activity. Thus, it is evident that using intents, one Android component can request action from the other components of Android.
Three of the core components of an application — activities, services, and broadcast receivers — are activated through messages, called intents.
Intent Types :
-------------------
Delving further, Intents can be Explicit or Implicit.
Explicit Intent:
An Explicit Intent is exactly what it means literally: an "explicit intention" to perform an action. Simply put, in this case, we define explicitly the Android component (Activity, Service or Broadcast Receiver) that needs calling.
Implicit Intent :
Here we do not specifically define the component that needs to be called. However, the Intent contains enough information to direct the system to fetch the correct one.
