Hello everyone! Today in this article, we'll be uncovering the fundamental components of Android apps and breaking them down for easy understanding. Let's dive right in.
Android apps typically consist of four main components:
- Activities
- Services
- Broadcast Receivers
- Content Providers
Let's take a closer look at each of these components:
Activities
An activity is like a window that users can interact with to
perform tasks. It might contain multiple fragments that handle specific parts
of the interface. For example, think of the login screen of a social media app.
Services
Services are behind-the-scenes workers that handle tasks
without a user interface. An example is a music app that keeps playing music
even if you switch to a different app or lock your screen.

Broadcast Receivers
Broadcast receivers listen for system-wide announcements, such as a low battery warning or device booting up. Apps can also create their own broadcasts. They help an app respond to specific events.

Content Providers
Content providers manage data and make it available to other
apps. They use methods like insert(), query(), update(), and delete() to
interact with the data. Each content provider has a unique URI, allowing apps
with proper permissions to access and share data. An example is accessing SMS
messages using the content://sms/inbox URI.
