In this way, you compile & build different APKs' for the same application targeting different devices, and you include different-sized images in your res/drawable directory depending on the device resolution that each individual APK is aimed at. The different APKs' can be published on the Play Store under the same application heading and will be automatically filtered by the Play Store Services APK (i.e. the Play Store app present on every Android device) based on that device's hardware.
