I've published an app for Android 2.2+. Android Market says it's supported by over 968 devices. Now a customer says he can't install the app. Android Market gives him this error message:
"Your device isn't compatible with this item."
So I checked if his "Archos 101 Internet Tablet (A101T)" (Firmware 2.4.82, Android 2.2.1, not rooted) was accidently excluded. From what I can see, this device is not even listed when clicking "Device Availability" in the Developer Console. When I search for Archos devices, I get the following list:
No A101T!
Q: Why isn't this device even listed? How can I make my app work on it?
Why isn't this device even listed?
Because that device model does not have the Android Market on it. It does not pass the CTS and does not ship from ARCHOS with the Android Market.
