What are the advantages of using ApplicationContext compared to ActivityContext in Android?

ApplicationContext lives throughout the entire runtime of the application, whereas ActivityContext is tied to the lifecycle of a specific Activity. This provides several advantages of ApplicationContext:

• Memory leak prevention: Using ApplicationContext prevents leaks that can occur when holding a reference to ActivityContext after the Activity has been destroyed.
• Availability everywhere: ApplicationContext is accessible from anywhere in the application, even if the Activity has not yet been created or has already been destroyed.
• Use for global operations: For example, accessing system services, creating Toast messages, starting services, etc.

Example of using ApplicationContext to create a Toast:

Toast.makeText(getApplicationContext(), "Message", Toast.LENGTH_SHORT).show();

While ActivityContext is better suited for UI operations related to a specific Activity, ApplicationContext is suitable for tasks that do not depend on the UI or the Activity's lifecycle.
