Hello,
how to deactivate all android device hardware buttons when I run the application.
Eg: Back, Home, Recent apps, Volume Up, Volume Down, Power button

Thank you for your answers.

procedure TfrmMain.FormKeyUp(Sender: TObject; var Key: Word; var KeyChar: Char;
Shift: TShiftState);
begin
if Key = sgiUpRightLong then
begin
Key := 0;
end;

if Key = sgiUpLeftLong then
begin
Key := 0;
end;

if Key = vkHardwareBack then
begin
Key := 0;
end;

if Key = ????? then
begin
....
end;
end;

OK,
FMX.KeyMapping ....
