Hello...
I'm working with Titanium for some time for Android (2.3 +) and iOS (5.0 +) platform and always encounter various problems related to dimensions, resolutions due to the large number of devices and the lack of standard related to the size of the screens. Ever tried using dp, px (that we know would not do), try to make a relationship dpi of the device with the screen size and then place the objects proportional to that on the screen .... but still is not the best solution! any tips?
