Android Emulator Support

Hi Team, i need create an android app for following size of screens:

480x700 - T-Mobile MyTouch 4G Slide, Samsung Epic Touch 4G, Samsung Galaxy S II
 
540x960 - HTC One, Series Motorola DROID RAZR MAXX, HTC EVO 3D
 
720x1280 - Samsung GALAXY Nexus, HTC Rezound

Now on Titanium Studio and documentation i cannot see the documentation about configure the emulator for support the screens

In the avd i can configure but my apps created on Titanium Studio are not showed.

Please, could the team explain to how can develop for support the models required for me ?

In titanium, in run configurations i have:

Screens WVGA854 and others, but, i need know the size of these screens?

thanks Jorge Luis
