Question

我正在尝试解析以下json

{
  "Id": "233ffba3-9796-4fff-32e3-535116e1297c",
  "Content": "lorem ipsum",
  "DateCreated": "2014-12-06T16:02:25Z",
  "ChatId": "33485bff-a95f-4a19-982d-532364db384d",
  "AccountId": "2da98191-c3de-49f0-a424-89ba7a0f448e",
  "Internal": false,
  "Quotation": false
}

到这个班级

public class Message extends Syncable<Message> implements Comparable<Message> {

    public UUID Id;
    public String Content;
    public Date DateCreated;
    public UUID ChatId;
    public UUID AccountId;
    public Boolean Internal;
    public Boolean Quotation;
    public Account Account;
    public Chat Chat;
    public Centipede<MessageRead> MessageRead;

    public Message() {
        this.MessageRead = new Centipede<MessageRead>();
    }
}

得到这个奇怪的错误

昨天一切正常，今天，Android Studio更新后，我收到了这个错误。

Answer 1

更新后可能您的Gson库丢失了试试这个

1）将Gson jar（在我的情况下，gson-2.2.4.jar）放入libs文件夹

2）右键单击它并点击'Add as library'

3）确保compile files('libs/gson-2.2.4.jar')文件中包含build.gradle

4）做一个干净的建筑

Answer 2

尝试从UUID更改为String，看看是否有效。
