ZXing Delphi not function in 10.3.2

[stacker_liew 5]

I created a qr code scan app using ZXing Delphi (https://github.com/Spelt/ZXing.Delphi) in 10.3.1, it's working fine, but after upgraded to 10.3.2, it's no longer scan qr code anymore, does any one face same problem with me?

Hi, 

I tested the demo at

https://github.com/Spelt/ZXing.Delphi/blob/v_3.0/demo/advancedTestApp/main.pas

 

To make it work, I had to apply the following changes

 

// 1) Moved this code from FormCreate to FormActivate
{$IFDEF ANDROID}
	FPermissionCamera := JStringToString(TJManifest_permission.JavaClass.CAMERA);
{$ENDIF}
	PermissionsService.RequestPermissions([FPermissionCamera], AccessCameraPermissionRequestResult, DisplayRationale);

// 2) Commented this code in FormCreate, because it is called before the CAMERA permission has been granted. Moved in AccessCameraPermissionRequestResult().
UpdateCaptureSettings(TCameraKind.BackCamera);

// 3) Changed AutoFocus to ContinuousAutoFocus.
CameraComponent1.FocusMode := TFocusMode.ContinuousAutoFocus;

// 4) Modified the SampleBufferReady event:
procedure TForm1.CameraComponent1SampleBufferReady(Sender: TObject; const ATime: TMediaTime);
begin
  // TThread.Synchronize(TThread.CurrentThread, SyncBitmap);
	// ParseBitmap();

  TThread.Queue(nil,
      procedure ()
      begin
        SyncBitmap();
        ParseBitmap();
      end);
end;

 

Also, changed TBarcodeFormat.Auto to TBarcodeFormat.QR_CODE.

Hi

There was een update today of the Advanced Scan App.  Its is now simplified and handles permissions to the onActivate event.

 

There were more problems with this demo app. You can check the changes in the last week.
