java.lang.String cannot be converted to JSONObject

待解析字符串 jsonStr;

JsonObject object=new JsonObject(jsonStr);

运行代码后异常

org.json.JSONException: Value 20171218141710_0001.MP4,THM ,LRV,20971520 at 0 of type java.lang.String cannot be converted to JSONObject

也是头回遇到，解决方法

if(jsonStr.startsWith(“\ufeff”)){

jsonStr= jsonStr.substring(1);

}

加载解析之前就可以
