How to get live app usage stats in android

The below code tracks todays usage of an app every second to get accurate usage time. The issue is it logs the same usage time every second, which is the usage time when the app was opened. The usage time does not change until the user reopens the app. The usage time should increase while I am using the app but it does not, how I can get live usage time of that app.

        Handler handler = new Handler(getMainLooper());

        handler.post(new Runnable() {
            @Override
            public void run() {
                long currentTime = System.currentTimeMillis();
                Calendar calendar = Calendar.getInstance();
                calendar.set(Calendar.HOUR_OF_DAY, 0);
                calendar.set(Calendar.MINUTE, 0);
                calendar.set(Calendar.SECOND, 0);
                calendar.set(Calendar.MILLISECOND, 0);
                long startMillis = calendar.getTimeInMillis();

                UsageStatsManager usageStatsManager = (UsageStatsManager) getSystemService(Context.USAGE_STATS_SERVICE);
                List<UsageStats> usageStats = usageStatsManager.queryUsageStats(UsageStatsManager.INTERVAL_DAILY,startMillis, currentTime);
                for(UsageStats stat : usageStats){
                    if(stat.getPackageName().equals(getPackageName())){
                        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
                            Log.d("MainActivity", "Usage time: " + stat.getTotalTimeVisible());
                        }
                    }
                }
                handler.postDelayed(this, 1000);
            }
        });

Heres the log while using the app(does not change if the app is running in foreground):

Even though you're polling getTotalTimeVisible every second, the time interval that you provide to queryUsageStats method through beginTime and endTime parameters is always the same (and refers to the past).

Because of that, the getTotalTimeVisible method call will always give you back the same value.
