public static boolean isHarmonyOs(){
    try {
        Class<?> buildExClass = Class.forName("com.huawei.system.BuildEx");
        Object osBrand = buildExClass.getMethod("getOsBrand").invoke(buildExClass);
        return "harmony".equalsIgnoreCase(osBrand.toString());
    }catch (Throwable e){
	return false;
