Question

我需要一些来自Javascript的项目，所以我使用Gson将JSON字符串转换为值，如下面的代码所示。

来自Java脚本：

 var  Items = [{ "ItemName": "Item1", "ItemPos": "1", "ItemValue":"value1"},{ "ItemName": "Item2", "ItemPos": "2", "ItemValue":"value2"}];

调用原生Android方法将这些值传递为 JSON.parse（items）。

在Native类中，我检索了以下值，

 List<Items> ItemsList; 
 Gson gson = new Gson();
 ItemsList= gson.fromJson(args[0].toString(), new TypeToken<List<Items>>(){}.getType());

我已将Item类声明如下。

  public class Items
   {
    public String Name;
    public String Position;
    public String Value;

  }

这些实现方法在本机源中运行良好。但是在对源进行混淆之后，这些实现方法无法正常工作。我收到“查找失败”错误。在反编译混淆代码时，Item类不存在于该位置“找不到匿名类”。甚至 List ItemsList的声明也不存在。如何解决这个问题？

Answer 1

I think that compiler may ignore the item class during Obfuscating

you must manually mention your missed class name in your proguard.txt file like as follows

-keep public class <your_class_name>

Answer 2

尝试添加：

-keep class com.xxx.yyy$Items { *; }

在Android中混淆后找不到匿名类
