Intent is a messaging object that can be use to pass data between different components (activities/service/BroadcastReceivers...), in other words Intents are asynchronous messages which allows Android components to request functionality from other components.

In Android we have two types of Intents.
Implicit Intent
Intent which will be used to call system apps like Gmail,Gallery,SMS...
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, textMessage);
sendIntent.setType("text/plain")
startactivity(sendIntent);
Intent which will be used to call our application components (Activities/Services...) which we know the exact name of the activity.
startactivity(intent);
