Sure! Here is an SEO-friendly HTML answer for the interview question "Difference between activity and service in Android":

Focus Keyword: Android Activity vs. Service

In Android, an activity represents a single screen with a user interface. It is typically a visual component that the user interacts with to perform actions within the app.

On the other hand, a service is a component that performs operations in the background without a UI. Services are used for tasks that need to continue running even when the app is not in the foreground.

While activities are more visible to the user and are essential for the user interface, services provide background functionality and can communicate with activities or other app components.

Understanding the differences between activities and services is crucial for developing efficient and well-performing Android apps.
