Time that an application is running

How do I determine how long an application has been running? Is there a broadc开发者_JAVA技巧ast each time an app is launched and shutdown?

I am trying to log the time spent using an application.

If you are interested in logging your own application's use, you can use System.currentTimeMillis() to get the start time, and diff it with the value returned when the app is closed.

To get the entire time the app is up, you would want to diff between onCreate() and onDestroy() of your foremost Activity class. For just the time the app is in the foreground, use onResume() and onPause() in each of your Activity classes and sum the time from each class.

Code:

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));
}
