hello Erel,
Whenever you get the time, would it be possible for you to add a 7" tablet screen size to B4A AVD Manager, maybe you can base it on the 2nd generation Nexus 7 using the N7 2nd gen DPI.
You have already created 4" and 6" phones, round and square watch faces, a 10" tablet but you've not created a 7" tablet screen side, this is all that is missing from the screen size drop down list.
