The video tutorial explains the four main components of Android applications: activities, services, broadcast receivers, and content providers. Each component serves a unique purpose and has a specific lifecycle. Activities are the entry points for user interaction, while services run in the background for long operations. Broadcast receivers handle system-wide events, and content providers manage shared data. The communication between these components is facilitated by Intents, and all components must be declared in the Android Manifest XML file.
