How to determine if an Android Service is running in the foreground?

public static boolean isServiceRunningInForeground(Context context, Class<?> serviceClass) {
      ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
      for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
         if (serviceClass.getName().equals(service.service.getClassName())) {
            if (service.foreground) {
               return true;
            }

         }
      }
      return false;
   }

private boolean isServiceRunning(String serviceName){
    boolean serviceRunning = false;
    ActivityManager am = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
    List<ActivityManager.RunningServiceInfo> l = am.getRunningServices(50);
    Iterator<ActivityManager.RunningServiceInfo> i = l.iterator();
    while (i.hasNext()) {
        ActivityManager.RunningServiceInfo runningServiceInfo = i
                .next();

        if(runningServiceInfo.service.getClassName().equals(serviceName)){
            serviceRunning = true;

            if(runningServiceInfo.foreground)
            {
                //service run in foreground
            }
        }
    }
    return serviceRunning;
}

If you want to know if your service is running in foreground just open some others fat applications and then check if service is still running or just check flag service.foreground.

   for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
      if (serviceClass.getName().equals(service.service.getClassName())) {
         return service.foreground;
      }
   }
   return false;
