Intent is a class which extends Object and the dictionary meaning of intent is intention or purpose. So, it can be described as the intention to do action."Intents are description of operation(message Object) to be perform."see this example

Intent  intent=new Intent(FirstActivity.this,SecondActivity.class);

its most significant use is in the launching of activities, where it can be thought of as the glue between activities. It is basically a passive data structure holding an abstract description of an action to be performed.
Android intents are mainly used to:
Start the service
Launch an activity
Display a web page
Display a list of contacts
Broadcast a message

Two types of intent are there
implicit intent and explicit intent
where implicit intent: intent provides information of available components provided by the system that is to be invoked.Example-

Intent intent=new Intent(Intent.ACTION_VIEW);  
intent.setData(Uri.parse("http://tech.queryhome.com"));  
startActivity(intent);

and Explicit intent: it provides details of class which is to be invoked.Example-

 Intent  intent=new Intent(FirstActivity.this,SecondActivity.class);
