Can you explain what components in Android are and how they interact with each other?

In Android, components are the fundamental building blocks of an application that perform different functions and interact with each other to ensure the application's operation. The main types of components:

• Activity — a screen with a user interface. Responsible for interacting with the user.
• Service — a component for performing background tasks without a user interface.
• Broadcast Receiver — receives and processes broadcast messages (events) from the system or other applications.
• Content Provider — provides access to application data to other applications.

Interaction between components occurs through Intent — an object that describes an action and data to be transferred. For example, an Activity can start another Activity or Service, send a Broadcast using an Intent.

Example of starting an Activity from another Activity:

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

Thus, components are connected through the Intent system, which provides a flexible and modular application architecture.
