The new feature now allows an app developer to upload several APK files–each one intended for a specific target device or set of devices–to only one product listing. Prior to the new feature for multiple APK uploads, app developers were allowed to upload only one APK file for every product listing. That has resulted in multiple listings of a single product, with each listing targeting a specific platform version, screen size, or chipset.
With this new feature, developers can now upload multiple apk files for their app into a single listing, with the different apk versions intended for different customers. For example, if u want your app to work properly on both Honeycomb and previous versions, you need not have several listings of the same app in the app store. You can simply place the apks under the same product listing, and the Android Market will choose the right apk to push to the user based on the the characteristics of the user’s device.
An awesome feature indeed !!! Way to go Google !! 🙂
