My android app is getting device not supported when trying to download with tablet

I have an android app on the market called D Bitly and I have a tablet user trying to download it and is getting "device not supported". I have double checked the market settings and it says that all devices are supported.

I have done a quick google search and I am not coming up with anything.

It requires 2 permissions:

android.permission.INTERNET

android.permission.ACCESS_NETWORK_STATE

and is for android 2.2 and up.

Any help would greatly be appreciated!

Edit: for those of you looking for an exact answer. The problem was being caused by copy protection. I have implemented the licensing service and removed the copy protection and all seems to be okay. Not exactly sure why copy protection doesn't play nicely wit开发者_Python百科h tablets or newer OS...

Your app is available for download for the XOOM and Galaxy Tab, so it's not a tablet-specific issue.

It's possible that the user in question has a modded ROM or something, perhaps causing some confusion with the Market servers. Beyond that, it may just be something peculiar with that Dell model.
