A Correct answer
Explanation

When Android starts up, it scans for activities that have the CATEGORY_LAUNCHER intent filter in their manifest. These activities are the app's entry points. Android displays their icons and names on the home screen (launcher), allowing users to tap them to launch the application. This is correct behavior.

AI explanation

This statement accurately describes real Android launcher behavior. When the device boots (or the launcher/home app starts), the system's Home app queries the package manager for all activities whose intent-filter declares the ACTION_MAIN action together with the CATEGORY_LAUNCHER category. For each match, it reads the associated icon and label from the manifest (or activity-alias) and places that icon on the home/app-drawer screen so the user can launch the app. This is exactly how Android populates the launcher — it's the standard, documented mechanism (Android Developers guide on the manifest element and intent filters), so the statement is True, not False.
