How do I determine how long an application has been running? Is there a broadcast each time an app is launched and shutdown?
I am trying to log the time spent using an application.

See Which Apps Are Running in the Background If you don't see Developer Options, scroll down and select About phone, then look for Build number and tap it seven times. Tap Running Services. It shows the apps currently running on your Android, how much RAM they're consuming, and how long each has been running.
Right-click the Start button (Windows Key+X) to bring up the hidden quick access menu and select Command Prompt. Then type: net stats srv and hit Enter. There you'll see Statistics since which gives you the date and time your system has been up and running.
An Android process is started whenever it is required. Any time a user or some other system component requests a component (could be a service, an activity or an intent receiver) that belongs to your application be executed, the Android system spins off a new process for your app if it's not already running.
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));
}
