AIR for Android maximum screen size?

Question

Hey folks!
Sorry if this question was already made here, but I couldn't find. Does anyone know if  AIR for Android has a maximum screen size for apps? I have this app developed for 1080p resolution, and my device (CS918 with Rockchip RK3188) is set to 1080p as well. But when I run it through FlashDevelop debug, it downsizes to 720p, still showing in fullscreen. My AIR is version 14.0.
Maybe it's my device, but since I don't have any other Android devices to test, I can't tell yet.
Thank you.

Thanks for letting me know! Here's the main thing I said:
What you say about fullscreen isn’t correct. That just dictates whether the status bar is showing or not.
The thing that controls how the stage is scaled is stage.scaleMode. The default value is “showAll”, and under that the stage will scale up so that either the height of the stage fills the height of the dvcid, or the width fills the width, depending on the ratio of the stage and the device.
“noBorder” is another useful mode. You could design a 14:9 stage and have content near the edges that isn’t vital. The stage would then scale to fill the screen, but would allow some content to go off the edges. It’s easy to support a range of devices, from 4:3 to 16:9, with that single 14:9 stage.
Some people use “noScale”, and then do all the mathematics themselves to get the contents of the stage to scale correctly. I just let Flash do that for me!
What moonlight says about calculating the pixels that are visible on a given device is true, and useful. Here’s my function for finding out where the top of the stage falls on the current device:
private static var landscapewidth:int = Math.max(Capabilities.screenResolutionX,Capabilities.screenResolutionY);
private static var landscapeheight:int = Math.min(Capabilities.screenResolutionX,Capabilities.screenResolutionY);
public static function landscapeTopEdge(thestage:Stage){
  return thestage.stageHeight * .5 - (thestage.stageWidth / landscapewidth * landscapeheight) * .5;
Because I pass in the stage to the function I can use its width and height as part of the calculation. That saves hard coding it for a particular stage size.
It’s a static function because I have it in a class with other device utilities. I would call it like this:
var topedge: Number = DeviceUtils.landscapeTopEdge(this.stage);
