    public static boolean isServiceRun(Context context,String serviceName){
        ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        
        List<RunningServiceInfo> rsis = am.getRunningServices(300);
        
        for (RunningServiceInfo runningServiceInfo : rsis) {
            if(runningServiceInfo.service.getClassName().equals(serviceName)){
                return true;
            }
        }
