Android APP - send via BroadcastChannel to website

[erich.wanker]

Das Hardware Back - denke ich - sollte so aussehen (ungetestet):

(aber WIE sende ich via BroadcastChannel ?)

Delphi-Quellcode:

uses FMX.Platform,FMX.VirtualKeyboard,FMX.Helpers.Android;

procedure THeaderFooterForm.FormKeyUp(Sender: TObject; var Key: Word;
  var KeyChar: Char; Shift: TShiftState);

var FService : IFMXVirtualKeyboardService; 
begin
  if Key = vkHardwareBack then
    begin
      TPlatformServices.Current.SupportsPlatformService(IFMXVirtualKeyboardService, IInterface(FService));
      if (FService <> nil) and (vksVisible in FService.VirtualKeyBoardState) then
        begin
          // Back button pressed, keyboard visible, so do nothing...
          key:=0;
        end
      else
        begin
          key:=0;
??????.. Sende via BroadcastChannel :   broadcaster.postMessage("_mein_hardware_back"); 
        end;
     end
..
