应用程序运行的时间

Question

如何确定应用程序运行的时间？每次启动和关闭应用程序时是否有广播？

我正在尝试记录使用应用程序所花费的时间。

Answer 1

如果您对记录自己的应用程序的使用感兴趣，可以使用System.currentTimeMillis()来获取开始时间，并使用应用程序关闭时返回的值进行区分。

要获得应用程序启动的整个时间，您可能需要在最重要的Activity类的onCreate()和onDestroy()之间进行区分。对于应用程序位于前台的时间，请在每个Activity类中使用onResume()和onPause()，并将每个类的时间相加。

Answer 2

代码：

ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
List<ActivityManager.RunningServiceInfo> services = activityManager.getRunningServices(Integer.MAX_VALUE);

long currentMillis = Calendar.getInstance().getTimeInMillis();
Calendar cal = Calendar.getInstance();

for (ActivityManager.RunningServiceInfo info : services) {
  cal.setTimeInMillis(currentMillis-info.activeSince);

  Log.i("TAG", String.format("Process %s has been running since: %d ms",info.process,  info.activeSince));
}

Answer 3

 long millisSinceBoot = SystemClock.elapsedRealtime();
         System.out.println("00000    "+millisSinceBoot);
         System.out.println("11111    "+values.get(position).activeSince+" "+values.get(position).process);
         long time = ((millisSinceBoot - values.get(position).activeSince)/1000);
         int[] vals = splitToComponentTimes(time);

         String time1 = vals[0]+":"+vals[1]+":"+vals[2];
         time_list.add(time);        
         timer.setText(time1);

         System.out.println("valssssss "+vals[0]+" "+vals[1]);
