答案 0 :(得分：1)
错误消息表示您尝试将JSON字符串值作为JSON对象访问。
答案 1 :(得分：0)
请发布您的代码和json回复， 在这种情况下，您可以尝试将String转换为jsonObject。
JSONObject jsonObject=new JSONObject(responseWeb);// responseWeb is String variable and you can convert string to JsonObject like this.
答案 2 :(得分：0)
如果要将字符串转换为JSONObject，则需要执行以下操作：
JSONObject obj = new JSONObject("{a string}");
更新：
data的外观如何？
JSONObject jo = new JSONObject(data);
也许您需要添加大括号：
JSONObject jo = new JSONObject("{" + data + "}");
答案 3 :(得分：0)
您正试图在代码中的某处将JSONString转换为JSONObject：
com.sunmobileappnow.mobileappnow.LoginActivity $ SigIn.doInBackground（LoginActivity.java:145）
或者你可以使用JSONTokener：
Object json = new JSONTokener(data).nextValue();
if (json instanceof JSONObject)
//you have an object
else if (json instanceof JSONArray)
//you have an array
