That would be an impossible task as there are literally thousands of Android models on the market today. As an example: One of my apps is available for 1687 devices as reported by the Google Play developer console.
As Rob mentioned any Android device with a CPU that supports the ARMv7 instruction set and running Android version 2.2 or later should be compatible.
If you’re interested to get more info on what exactly didn’t work for the customer that cancelled the order you can log in to your Merchant account and look at the transaction details. You should see an email address there which you could use to inquire about which model was used and what the problem was.
If there is some compatibility issue with a specific device, you can manually exclude that device in the developer console. In the “Product Details” section scroll down to the “Supported Devices” section and click “Show Devices”. There you’ll be able to search for a specific device and exclude it.
