Summary

Aplication Fundamentals

• Android package .apk contains the content that the app requires at runtime
• Android App Bundle .aab contains the rest of the content with metadata.
• All Android apps run isolated from other applications for security. The app is also only has access to what it needs in order to work and nothing more.

App Components

• Activities - single screen with a user interface
• Services - general purpose to keep app running in background
• Broadcast Receivers - allows system to deliver events to the app
• Content Providers - manages shared set of app data in SQL database
