Finally the Google Android Market will allow developers to upload different versions of the same app without creating separate listings. This means that when a developer uploads their app for the phone they can also upload the Tablet version. This should create easier and cleaner updating of apps on the market. On top or this, app developers will no longer need to add change logs and update descriptions in so many different locations.
Multiple APK support gives you a variety of ways to control app distribution. For example, you could use it to create separate APKs for phones and tablets under the same product listing. You could also use it to take advantage of new APIs or new hardware capabilities without impacting your existing customer base.
The Market will now decide which app version you need based on screen size whether its the GL texture-compression formats or standard Android version. Now users will only see the app with comments and listing details without having to find the correct version for the device they are using. This has been something that app developers and your average user alike will be able to appreciate. No more downloading the wrong version of an app for your device.
Now that the Google Android Market allows multiple uploads with one listing we will likely see the Market grow even faster than it already is. Along with growth we may see many more apps available for Tablets in the near future since they will not have to be completely separate from the phone version in the listing.
Let us know as a developer if this new feature of the market has helped you in your current processes as well as how much easier things have been made for you. As a user we would also be interested to know if this has improved your experience on the Android Market as far as finding the correct version of the app your looking for.
