I'm writing an Android app in delphi 10.4.2 and when I write the scaling code in the OnGesture event of the image1 control, the IDE says "uncleared identifier" for the ScaleFactor. I've looked at it repeatedly, but I don't know where the problem is coming from, so I'm looking for help.
Here is my code:
unit Unit1;

interface

uses
  System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants,
  FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs,
  FMX.Controls.Presentation, FMX.StdCtrls, FMX.Objects, FMX.Layouts,
  FMX.ExtCtrls,
  FMX.Gestures,
  FMX.Edit,
  System.IOUtils;
type
  TForm1 = class(TForm)
    Label1: TLabel;
    Button1: TButton;
    ImageViewer1: TImageViewer;
    Image1: TImage;
    GestureManager1: TGestureManager;
    Button2: TButton;
    procedure Button1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure ImageViewer1Gesture(Sender: TObject;
      const EventInfo: TGestureEventInfo; var Handled: Boolean);
    procedure Image1Gesture(Sender: TObject; const EventInfo: TGestureEventInfo;
      var Handled: Boolean);
  private
    { Private declarations }
     FLastDistance: Integer; 
     const MIN_DIM = 100; 
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
  G_lujing:string='';
  G_myDir:string='MyBrain';
implementation

{$R *.fmx}
{$R *.LgXhdpiTb.fmx ANDROID}
{$R *.SmXhdpiPh.fmx ANDROID}
{$R *.iPhone55in.fmx IOS}

procedure TForm1.FormCreate(Sender: TObject);
var path: string; fileName:string;
begin
  path:=TPath.GetSharedDownloadsPath;
  path := TPath.GetDirectoryName(path);
  G_lujing:=TPath.Combine(path, G_myDir);
  try
    if not TDirectory.Exists(G_lujing) then  TDirectory.CreateDirectory(G_lujing);
    fileName := TPath.Combine(G_lujing, 'test.txt');
    if not FileExists(fileName) then TFile.WriteAllText(fileName, 'Hello world!');
  except on
    E: Exception do ShowMessage('An error occurred while creating the directory:' + E.Message);
  end;
end;

procedure TForm1.Image1Gesture(Sender: TObject;
  const EventInfo: TGestureEventInfo; var Handled: Boolean);
begin
  if EventInfo.GestureID = igiZoom then
  begin
    // Zoom the image using ScaleFactor
    Image1.Scale.X := Image1.Scale.X * EventInfo.ScaleFactor;
    Image1.Scale.Y := Image1.Scale.Y * EventInfo.ScaleFactor;
    // Adjust the image position based on the gesture focus point
    Image1.Position.Point := EventInfo.FocusPoint;
  end;
end;

end.

You cannot deploy a file using Deployment Manager to a folder outside of the application. It might help to know why you actually want to, as there are issues inherent with dealing with "public" folders, especially on later versions of Android. 

Here's what I was thinking: if the apk installer could deploy the local documentation to a public directory, it would make it easier for me to manually modify them later in the phone.

I am developing an Android app and I want to deploy a local file to the public directory of my phone. I have done the following and tried many times, but I am unable to deploy the file to my phone. What is the problem? Could any of you help me?
1. Select the compilation configuration and target platform: select "Debug configration - Android 64-bit platform" in Project > Deployment
2、Add the line for deploying images: In project>Demplyment, click the "add files" button, the parameters are as follows
local path=mypic\ 
Local Name=pic.jpg
Type=File
remote path={sdcard}\Download\MyBrain\mypic\   
remote name=pic.jpg
I don't feel like there's anything wrong with it, but I just can't deploy this image to my phone. What is the problem?
