Haxe Help - Manipulating Android Back Button Action

Basically, I use Stencyl engine to make games. The engine uses Haxe and doesn't support everything that Haxe supports.

I want to manipulate he android 'back button' press. Stencyl supports code mode where I can write a haxe code. I wanted to overwrite android's default back button press. When player is playing the game, if he press back button, the game goes to background. Instead, I want the level to restart when backbutton is pressed. Can this be accomplished with any available source for Haxe?

I tried searching for any code help but can't find one. That's why messaging here. Appreciate any help.

P.S: Stencyl developer may not be a real developer for you. If that's the case, I'm not a developer. I'm just someone who uses all the resources to achieve what I want. So please avoid such topics which isn't going to help anybody.

You could try below code

Lib.current.stage.addEventListener(openfl.events.KeyboardEvent.KEY_UP, checkKeypress);

...

private function checkKeypress(e:openfl.events.KeyboardEvent):Void
{
    switch (e.keyCode)
    {
        case openfl.ui.Keyboard.ESCAPE:
            e.stopImmediatePropagation();
            restartLevel();
    }
}
private function restartLevel():Void
{
    //your code to restart level here
}
