PDF on IOs

The pdf file isn't opened, but the os shows the Acrobat button choice. Clicking on it doesn't do anything.

procedure TForm1.RunPDFClick(Sender: TObject);
var
p: TTMSFNCPDFLib;
begin

p := TTMSFNCPDFLib.Create;
try
	p.BeginDocument(System.IoUtils.tpath.GetDocumentsPath + 'test.pdf');
	p.NewPage;
	p.EndDocument(True);
finally
	p.Free;
end;

end;

Due to security the file will not be opened. TMS iCL is available with some native controls that support opening files

Thanks
