[Android] `StageOrientation.DEFAULT` never triggers on `StageOrientationEvent.ORIENTATION_CHANGING` when event is prevented (`event.preventDefault`)

[2jfw]

OS: Android 10

AIR: 51.1.3.6

App Descriptor:

<aspectRatio>any</aspectRatio>
<autoOrients>true</autoOrients>

Aim: I want to receive the StageOrientationEvent but I don't want the stage to actually rotate. I'm using event.preventDefault() on StageOrientationEvent.ORIENTATION_CHANGING in order to block the stage from rotating.

Code:

private function init() : void
{
	stage.addEventListener(StageOrientationEvent.ORIENTATION_CHANGE,
	                       onChangeStageOrientation);
	stage.addEventListener(StageOrientationEvent.ORIENTATION_CHANGING,
	                       onChangingStageOrientation);
}

private function onChangeStageOrientation(event : StageOrientationEvent) : void
{
	trace("onChangeStageOrientation " + event.toString());
}


private function onChangingStageOrientation(event : StageOrientationEvent) : void
{
	trace("onChangingStageOrientation " + event.toString());

	if (event.afterOrientation == StageOrientation.ROTATED_LEFT
	    || event.afterOrientation == StageOrientation.ROTATED_RIGHT)
	{
		event.preventDefault(); // commenting out this line will have all events received correctly!
	}
}

Issue: In onChangingStageOrientation calling event.preventDefault() will cause onChangeStageOrientation to be never called. The function onChangingStageOrientation is also never called with event.afterOrientation == StageOrientation.DEFAULT, though the "prevent event" part should not affect the listener from triggering. Function onChangingStageOrientation is only called for StageOrientation.ROTATED_LEFT, StageOrientation.ROTATED_RIGHT and StageOrientation.UPSIDE_DOWN when the event is prevented default.

Other Observations: Using <aspectRatio>portrait</aspectRatio> or <aspectRatio>landscape</aspectRatio> will lead to no events dispatched at all. I would suggest, that both orientation events are always fired, as there can be scenarios, where you need them, no matter if the stage actually rotates or is set to a fixed aspect ratio and even when it does not auto orientate.

Just as an aside you can use the device orientation events in the application ane to achieve this: https://docs.airnativeextensions.com/docs/application/device-information/orientation-events

Ah, many thanks for pointing out! I'm actually using the Application ANE, so I will just switch to that functionality then 🍻👍

I can confirm this is working as intended and the events are dispatched, including the missing "default" orientation.

@ajwfrost : Could you briefly have a look into the missing "default" orientation event for the scenario from above?
