【Multiple APK Support】

　　Multiple APK support is a feature on Google Play that allows you to publish different APKs for your application that are each targeted to different device configurations. Each APK is a complete and independent version of your application, but they share the same application listing on Google Play and must share the same package name and be signed with the same release key. This feature is useful for cases in which your application cannot reach all desired devices with a single APK.
