Android Application Design tips: Google Play and attributes

Google Play filters apps visible to usersProgramSo that users can only view and download applications compatible with their devices.

Google Play checks the <uses-SDK> attribute in each application list to establish its compatible version range, then, the application is displayed and hidden based on the comparison of the user's Android system version API.
