Hi all,
I have been testing ORIENTATION_CHANGE, ORIENTATION_CHANGING and RESIZE events across iOS and Android. Tests done using AIR3.7/Flex4.6.0.
I've been starting the app in 'default' orientation, then rotating it.
I've also started the app in landscpe mode, then rotated it back.
Almost all devices work fine (though there are differences in the order of events between iOS and Android) except that, disturbingly, ORIENTATION_CHANGE does not fire on iPod 4th (iOS6.1.3) or iPhone 5 (iOS6.1.4) when starting in landscape, even though ORIENTATION_CHANGING does. Not sure if it's iOS related or not. It seems to happen on devices where the springboard doesn't rotate to orientation (i.e. rotating iPad reshuffles the icons on springboard, but rotating the iPhone/iPod does not) - this means that the app rotates just after it is launched.
Is this a bug that is likely to be addressed? Watching for 'ORIENTATION_CHANGE' event is pretty standard behaviour for detecting orientation changes!
Here is my test:
iOS - start in portrait (iPad1 iOS5.1.1, iPod4th iOS6.1.3, iPhone5 iOS 6.1.4)
RESIZE
RESIZE
Now rotate the device left
ORIENTATION_CHANGING
RESIZE
ORIENTATION_CHANGE
iPod 4th and iPhone 5 - start landscape before launching app
RESIZE
ORIENTATION_CHANGING
RESIZE
.... no 'change' event 
<-- HERE IS THE ERROR
Now rotate device back to default
ORIENTATION_CHANGING
RESIZE
ORIENTATION_CHANGE
iPad 1 - start landscape before launching app
RESIZE
RESIZE
Now rotate the device left
ORIENTATION_CHANGING
RESIZE
ORIENTATION_CHANGE
And for those that are interested, here is the difference between Andoid (phone only - tablet tests to come) and emulator:
Emulator (Flash debug player - start default)
RESIZE
RESIZE
Rotate left
ORIENTATION_CHANGING
RESIZE
RESIZE
ORIENTATION_CHANGE
Android Samsung Galaxy S3 - start default
RESIZE
RESIZE
Rotate back to default
ORIENTATION_CHANGING
ORIENTATION_CHANGE
RESIZE
Android Samsung Galaxy S3 - start landscape
RESIZE
RESIZE
Rotate back to default
ORIENTATION_CHANGING
ORIENTATION_CHANGE
RESIZE
