Why do Android apps written in actionscript 3.0 in Adobe Flash weigh so much?

Question

Android

Hello.
I created a simple calculator (or rather, not even a calculator, but simply by pressing a button a number is displayed) on actionscript 3.0 in Adobe Flash
Here is the code:

import flash.events.Event;
stop();
Multitouch.inputMode=MultitouchInputMode.TOUCH_POINT;

this.btn1_btn.addEventListener(TouchEvent.TOUCH_BEGIN,f1);
this.btn2_btn.addEventListener(TouchEvent.TOUCH_BEGIN,f2);
this.btn3_btn.addEventListener(TouchEvent.TOUCH_BEGIN,f3);
this.btn4_btn.addEventListener(TouchEvent.TOUCH_BEGIN,f4);
this.btn5_btn.addEventListener(TouchEvent.TOUCH_BEGIN,f5);
this.btn6_btn.addEventListener(TouchEvent.TOUCH_BEGIN,f6);
this.btn7_btn.addEventListener(TouchEvent.TOUCH_BEGIN,f7);
this.btn8_btn.addEventListener(TouchEvent.TOUCH_BEGIN,f8);
this.btn9_btn.addEventListener(TouchEvent.TOUCH_BEGIN,f9);
this.btn0_btn.addEventListener(TouchEvent.TOUCH_BEGIN,f0);

function f1(e:TouchEvent):void{this.monitor_txt.appendText('1');}
function f2(e:TouchEvent):void{this.monitor_txt.appendText('2');}
function f3(e:TouchEvent):void{this.monitor_txt.appendText('3');}
function f4(e:TouchEvent):void{this.monitor_txt.appendText('4');}
function f5(e:TouchEvent):void{this.monitor_txt.appendText('5');}
function f6(e:TouchEvent):void{this.monitor_txt.appendText('6');}
function f7(e:TouchEvent):void{this.monitor_txt.appendText('7');}
function f8(e:TouchEvent):void{this.monitor_txt.appendText('8');}
function f9(e:TouchEvent):void{this.monitor_txt.appendText('9');}
function f0(e:TouchEvent):void{this.monitor_txt.appendText('0');}

When publishing this calculator, the .apk file weighs almost 9 megabytes.
Why? because there's nothing here

Answer 1

Along with the archive comes Adobe AIR Runtime, a virtual environment for running AIR applications on devices, an analogue (UNITY or JRE), if AIR is already installed on the device, it is not necessary to attach it to the archive, look in the APK packaging settings, the type parameter: Include AIR, the size will be reduced, but without AIR the user will not launch the application, in this case, the developers release 2 versions: APK (without AIR) and APK (with AIR)

Answer 2

Open the APK and see what weighs so much ;-) Well, this is a regular archive.

Answer 3

Adobe AIR was automatically added
