Android Intent

Intents are used as a message passing mechanism. It works within your application, between the applications.  One of the most common uses for intents is to start new activities. It is either explicitly (by specifying the class to load) or implicitly (by requesting that an action be performed on a piece of data).


Explicit Intent

startActivity(new Intent(FirstActivity.this,SecondActivity.class));

Implicit Intent

Intent intent = new Intent (Intent.ACTION_DIAL, Uri.parse 
                           ("tel: 123-4567"));
StartActivity (intent);
