I've just come across the same "thing" in my app the problem is that the function Ti.Platform.DisplayCaps.platformHeight
on android returns the value in pixel but in iOs is Dpi.
as workaround for this discrepancy I've put thi in my app:
if (osname == 'android')
{
densityMultiplier = Ti.Platform.displayCaps.logicalDensityFactor;
}
if (osname == 'iphone')
{
densityMultiplier = 1;
}
and to set the hight of the view:
$.myView.setHight(newHight * densityMultiplier)
I hope this is helpful.
