Activities

  • Activities are the primary building blocks of an Android application. They represent a single screen or user interface (UI) and handle user interactions.
  • Activities are responsible for displaying content, collecting user input, and managing the application’s lifecycle.

Services

  • Services are background processes that run independently of activities.
  • They are used to perform long-running tasks, such as network operations, data processing, or playing music.
  • Services can be started, stopped, and bound to activities as needed.

Broadcast Receivers

  • Broadcast receivers are components that listen for and respond to system-wide events, such as incoming phone calls, battery level changes, or network connectivity.
  • They are typically used to handle events that require immediate action or to notify other components of a change in state.

Content Providers, Android for programmers an app driven approach

  • Content providers are components that manage and share data between different applications.
  • They provide a secure and consistent way to access data from various sources, such as databases, files, or web services.
  • Content providers can be used to share data between activities within the same application or with other applications.

Android Application Lifecycle

The Android application lifecycle refers to the sequence of events that an application goes through from its creation to its termination.Understanding the application lifecycle is important for managing resources, handling user interactions, and ensuring a consistent user experience.
