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.

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?

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.
