What are the Android application components?

Android application components are the building block essentially used in the Android application. The application manifest file named Android manifest.xml couples the components. This describes each component of the application and describes how they interact, and then the processing activity takes place.

There are four main components, which are:

• Activities: They show the UI and handle the interaction of the users in smartphone screen.
• Services: They take care of the processing associated with the application.
• Broadcast Receivers: They handle the communication process between Android OS and application.
• Content Providers: They handle issues with data and database management.
