  Classes, SysUtils, Forms, Controls, Graphics, Dialogs;

type

  { TForm1 }

  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    procedure Minimize(Sender: TObject);

  public

  end;

var
  Form1: TForm1;
  Count: integer;

implementation

{$R *.lfm}

{ TForm1 }

procedure TForm1.FormCreate(Sender: TObject);
begin
  Application.OnMinimize := @Minimize;
  Count := 0;
end;

procedure TForm1.Minimize(Sender: TObject);
begin
  Count := Count + 1;
  Caption := IntToStr(Count);
end;

I know there is a much better (native) solution, but I was unable to
find it. So one potential workaround can be: add a Timer to your Form.
Then update it e.g. every 0.1 seconds, and keep some memory of what
was the last time of update. E.g. like this:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var 
LastUpdate: TDateTime;begin  if (Now - LastUpdate) * 24*60*60 > 1.0
then    WriteLn('App was offline for more than one second, resuming
operation');  LastUpdate := Now;end;

Does this do the trick? (tested only on Windows)
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i unit
Unit1; {$mode objfpc}{$H+} interface uses  Classes , SysUtils , Forms
, Controls , Graphics , Dialogs , StdCtrls; type   { TForm1 }   TForm1
= class(TForm)    Label1: TLabel;    procedure FormCreate(Sender:
TObject);  strict private    FDeactivated: Integer;  private   
procedure MyDeactivate(Sender: TObject);  public   end; var  Form1:
TForm1; implementation {$R *.lfm} { TForm1 } procedure
TForm1.FormCreate(Sender: TObject);begin  Application.OnDeactivate :=
@MyDeactivate;  FDeactivated := 0;end; procedure
TForm1.MyDeactivate(Sender: TObject);begin  Inc(FDeactivated); 
Label1.Caption := IntToStr(FDeactivated);end; end.

Quoteor he press the home button on device we would like the keep
count of that....

You can try handle  jForm "OnSpecialKeyDown" event to check for
"home"  key...

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.AndroidModule1SpecialKeyDown(Sender: TObject; 
keyChar: char; keyCode: integer; keyCodeString: string; var mute:
boolean);begin    if keyCode = 3 then        // 4 --> keyback      
begin           ShowMessage(keyCodeString);    //HOME ...    end;end;

I think the original question needs to be refined.

If you are trying to establish if the user is still "active" and if
they are not active then make them reenter their credentials, then
another approach may be required.
One way to do that is have the user regularly contact the server.
