Actually, the Nexus 7 is a large , tvdpi , and the Galaxy Nexus is normal and xhdpi . However, I think you are right to exclude as few devices as possible; it's probably best not to rule out large or tvdpi devices across the board.
Fortunately, you can exclude devices from the distribution through the Play Store based on each model:
- Go to the Developer Console.
- Scroll down to "Supported devices" and click "Show devices."
- Scroll or find "Nexus 7".
- Click Exclude.
- Click Finish.
Once you get the kinks developed on the Nexus 7, just go back and turn it on again.
