Datasnap application dies after a while

Hello everyone,

 

I am using Delphi 10.3.3

 

got here Android 10 (also Android 8). Battery Optimization is off . The problem only happens if my Device is on the charger. After approximately 48hrs it dies .

I tried to solve this by waking the device up periodically (after 8hrs) . Today it last sent data to the server at 3:00 , so I thought it is dead. But to my big surprise ,

it still woke up at 08:00 . Unfortunately after touching the screen , to try to open something . Android forced me to close the app.

Here is the part of the code :

(excuse me for the length, it looks to be long , but is is the bare minimum , I thought I'd include every procedure and function I use in order to perhaps help someone smarter then me see if I am leaking memory or doing something horrible, note : this very same code is NOT crashing or hanging after weeks if Device is not on the charger) 

procedure TMain.Timer1Timer(Sender: TObject);
var SyncTime : TDateTime;
    TransferTime : TDateTime;
begin
  if FDEviceName = 'error' then Exit;

  Timer1.Enabled:=false;

  SyncTime:=inireadDt(FilePath+'/Configuration/settings.conf','Tasks','SyncTime');

  if MinutesBetween(now,SyncTime) >= 1 then
  begin
    if isDeviceIdleMode = false then
    begin
      BatteryLevel := GetBatteryLevel;
      GetWifiStatus;

      SendDeviceStatus;

      iniwrite(FilePath+'/Configuration/settings.conf','Tasks','SyncTime',now);

      if GetBatteryCharging = 0 then WakeTime := 0;

      if GetBatteryCharging in [1,2] then inc(WakeTime);
      // to prevent app from dying we wake up device on the charger after 8 hrs
      if WakeTime = 480 then
      begin
        WakeUpNow;
        WakeTime:=0;
      end;

    end;
  end;

  Timer1.Enabled:=true;
end;

function TMain.GetBatteryLevel;

      -49..0 : SignalStrength:=4;
      -59..-50 : SignalStrength:=3;
      -70..-60 : SignalStrength:=2;

    end;

Help would be much appriciated. Thank you for your time.

Hi,

 

I only do this FULL_WAKEUP because it keeps my software running actually longer . (But only when on charger. )

 

So I only wake up in order to help my software stay alive, i would be fine without this... maybe I will do it with

PARTIAL_WAKE_LOCK

instead.

 

 

If the Device is NOT on the charger ... it runs for weeks (with or without FULL_WAKEUP).

I think its no problem to re-start a WakeUp several times, e.g. by timer every 10 sec., to keep it alive.

The user won't notice this.

I have altered the WakeUpNow procedure a bit :


  

procedure TMain.WakeUpNow;
var
  PowerManager : JPowerManager;
  WakeLock : JPowerManager_WakeLock;
begin

  PowerManager := TJPowerManager.Wrap(TAndroidHelper.Context.getSystemService(TJContext.JavaClass.POWER_SERVICE));

//  WakeLock := PowerManager.newWakeLock(TJPowerManager.JavaClass.FULL_WAKE_LOCK or TJPowerManager.JavaClass.ACQUIRE_CAUSES_WAKEUP,StringToJString('NE_PACK'));
  WakeLock := PowerManager.newWakeLock(TJPowerManager.JavaClass.PARTIAL_WAKE_LOCK,StringToJstring('NE_PACK'));

  WakeLock.acquire;

  WakeLock.release;
  WakeLock:=nil;

end;

I am not 100% sure , but this will wake up the CPU and imediatelly allow it to go back to sleep or whatever it was doing.

 

I also altered the Timer1.Timer1Timer Procedure a bit , for more security I start a Anonymous Thread for this job. Also I have changed the Connection and Communication Timeout to 100ms instead of 500ms .
  

procedure TMain.Timer1Timer(Sender: TObject);
var SyncTime : TDateTime;
    TransferTime : TDateTime;
begin
  if FDEviceName = 'error' then Exit;

  Timer1.Enabled:=false;

  SyncTime:=inireadDt(FilePath+'/Configuration/settings.conf','Tasks','SyncTime');

  if MinutesBetween(now,SyncTime) >= 1 then
  begin
    if isDeviceIdleMode = false then
    begin
     // created a thread and set the timeout to 100 intead of 500
      TThread.CreateAnonymousThread(procedure()
      begin
        BatteryLevel := GetBatteryLevel;
        GetWifiStatus;

        SendDeviceStatus;
      end).Start;

      iniwrite(FilePath+'/Configuration/settings.conf','Tasks','SyncTime',now);

      if GetBatteryCharging = 0 then WakeTime := 0;

      if GetBatteryCharging in [1,2] then inc(WakeTime);
      // to prevent app from dying we wake up device on the charger after 8 hrs
      if WakeTime = 480 then
      begin
        WakeUpNow;
        WakeTime:=0;
      end;

    end;
  end;

  Timer1.Enabled:=true;
end;

 

Now I will have to wait. Unfortunately for me it takes almost 2 Days to find out if this solved my problem . Or not.

Good luck.

So this means the changes work at least fine for a short period now ?

 

So I thought your original issue should some kind of reproduceable, or was it more or less unpredictable ?

Nevertheless, I think that permanently re-ensuring that you really want to stay wake should solve it, since that starts a new wake session hopefully.

it is Reproducible 🙂 it dies after approx 48hrs 😞 . Always but only on Charger.

 

I made now this above version and another where I only send data every 15 minutes to see if that makes a difference.

 

If neither of them does . Then I will simply check if I am on charger and send data for maybe 8 hrs and after that stop until someone turns the device on .

 

Maybe I am attacking this from a completely wrong standpoint, maybe the Android Device is not meant to be used like this.

(if I only have the timer... it works, I am dying 100% because of sending data, and this only happens on the Charger, which is perhaps happening because on the
Charger the Android Device is doing a lot more Maintenance jobs and maybe killing my app to release memory for itself... )

I am running in Kiosk mode 🙂 ( sorry I thought it was irrelevant... ) but this only helps that much if my app dies... it is simply restart... but only if the user actually interacts with the thing.

I would not believe this if not seeing it with my own eyes .

 

it looks like I need to check if I am in Interactive mode . If I am not in interactive mode then I must do the Reports Back to the Server less often . 15 Minutes instead of 1 Minutes for example.

And behold I started the App on 31.03.2021 14:02:40 , and it is 06.04.2021 06:11 and is still running . All other Versions with Anonymous Threads etc. all died. Only this one with 15 Minutes between the jobs survived. I've read somewhere that an app is only allowed to execute once in 10 minutes if in Doze mode. But can't seem to recall where . Maybe this was the reason why it was killed after two days when running on a 1 Minute Interval.

The code looks like this :

  

  if isInteractive = true then
    SyncPeriod := 1
  else
    SyncPeriod := 15;

  SyncTime:=inireadDt(FilePath+'/Configuration/settings.conf','Tasks','SyncTime');

  if MinutesBetween(now,SyncTime) >= SyncPeriod then
  begin
    if isDeviceIdleMode = false then
    begin
      BatteryLevel := GetBatteryLevel;
      GetWifiStatus;

      SendDeviceStatus;

      iniwrite(FilePath+'/Configuration/settings.conf','Tasks','SyncTime',now);
    end;
  end;
