How do I get the version number of the current FMX project in Delphi 12?

Question

The Delphi 12 IDE allows editing of the FMX module version number in Project | Options | Application | Version Info.

How can I access the build number of my FMX project in code?

Answer 1

GetVersionString (from FMX.Platform.IFMXApplicationService) returns a string with the version number of the application.

All the details are available here:

• https://docwiki.embarcadero.com/Libraries/Athens/en/FMX.Platform.IFMXApplicationService.GetVersionString

Answer 2

Delphi's documentation sucks. It doesn't show the correct way to use the function.

It should be like this:

function GetAppVersion: string;
var
  AppService: IFMXApplicationService;
begin
  if TPlatformServices.Current.SupportsPlatformService(IFMXApplicationService, IInterface(AppService)) then
    Result := AppService.AppVersion
  else
    Result := 'Version info not available';
end;
