Android split screen to run two apps stage height problem

[pol2095]

Problem Description

On Android when I run two apps using split screen simultaneously, stage height can change.

• AIR SDK 51.2.2.6
• Android 16
• I reproduce it on Pixel 7 Pro and Pixl 10 Pro

Steps to Reproduce

Image 1 : without spleet screen, stage height is 1080

Image 2 : I split screen using Google Chrome (or other app) and my Air app, stage height is 1080

Image 3 : tap and hold the screen divider line and drag it left, stage height is 1017 ???

Image 4 : tap and hold the screen divider line and drag it right (initial position : Image 2) stage height is 954 ???

minimal code example:

package
{
	import flash.display.Sprite;
	import flash.display.StageAlign;
	import flash.display.StageScaleMode;
	import flash.events.Event;
	import flash.text.TextField;
	import flash.text.TextFormat;
	import flash.events.MouseEvent;

	public class Main extends Sprite
	{
		private var textField:TextField = new TextField();
		
		public function Main()
		{
			this.addEventListener(Event.ADDED_TO_STAGE, addedToStageHandler);
		}
		
		private function addedToStageHandler(e:Event):void
		{
			this.removeEventListener(Event.ADDED_TO_STAGE, addedToStageHandler);
			stage.scaleMode = StageScaleMode.NO_SCALE;
			stage.align = StageAlign.TOP_LEFT;
			
			textField.background = true;
			textField.border = true;
			textField.y = 80;
			textField.width = 500;
			textField.height = 200;
			
			var format:TextFormat = new TextFormat();
			format.size = 40;
			
			textField.defaultTextFormat = format;
			this.addChild(textField);
			
			var sprite:Sprite = new Sprite();
			sprite.graphics.beginFill(0x0000FF);
			sprite.graphics.drawRect( 0, 0, 200, 200);
			sprite.graphics.endFill();
			sprite.y = textField.y + textField.height + 20;
			sprite.addEventListener(MouseEvent.CLICK, mouseClickHandler);
			this.addChild( sprite );
		}
		
		private function mouseClickHandler(event:MouseEvent):void
		{
			textField.text = "\n\nstageHeight : " + stage.stageHeight;
		}
	}
}

I don't know if it's an Air or Android bug, but it's impossible to use Screen.mainScreen.safeArea if stage height can change... in Image 2 the top of the stage is under status bar and the bottom of the stage is under navigation bar but that's not the case in Image 4. I represented the stage bounds in a red rectangle : Image 2

Image 4

status bar height : 63 navigation bar height : 63 954 + 63 + 63 = 1080
