Android用來判斷某個服務是不是已經Working

/**     * 用来判断服务是否运行.     * @param context     * @param className 判断的服务名字：包名+类名     * @return true 在运行, false 不在运行     */          public boolean isServiceRunning(Context context,String className) {                      boolean isRunning = false;              ActivityManager activityManager =                   (ActivityManager)context.getSystemService(ACTIVITY_SERVICE);               List<ActivityManager.RunningServiceInfo> serviceList               = activityManager.getRunningServices(Integer.MAX_VALUE);              if (!(serviceList.size()>0)) {                  return false;              }              for (int i=0; i<serviceList.size(); i++) {                  if (serviceList.get(i).service.getClassName().equals(className) == true) {                      isRunning = true;                      break;                  }              }              Log.i(TAG,"service is running?=="+isRunning);              return isRunning;          }
