GSON錯誤

Question

我用下面的代碼到我的JSON字符串轉換爲對象：

Gson gson = new Gson();    
EntPocketPCDataCollection entPocketPCDataCollection = gson 
      .fromJson(strJson, 
      EntPocketPCDataCollection.class); 

我有這些類：

public class EntPocketPCDataCollection extends ArrayList<EntPocketPCData> { 

    private static final long serialVersionUID = 1L; 

} 

和

public class EntPocketPCData { 

    private String strFormat = "Can not convert %s to %s value for column %s"; 

    public String Command; 
    public EntColumn[] Columns; 
    public List<List<String>> RowsList; 
    public String TypeName; 
} 

這些代碼行可以在Emulator，Asus tablet，galaxy note，galaxy s和HTC Sensation上正常工作。但是，僅在具有Android 2.2的HTC Desire HD A9191設備上出現以下錯誤。

爲什麼？

Answer 1

我們曾經嵌在我們的應用程序上的Desire HD與GSON一個問題，因爲不是我們gson.jar文件在運行時使用，但一個過時的版本，HTC發佈了它的ROM。我想你也有類似的問題。一種可能的解決方法是使用jarjar（http://code.google.com/p/jarjar/）以確保您的應用程序使用您的gson jar。

編輯 最可能的是同一個問題在這裏：GSON + HTC Desire: Conflict. Possible solution jarjar.jar causes error
