Question

我使用以下代码将我的Json字符串转换为object：

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

我有这些课程：

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;
}

这些代码可以在Emulator，Asus平板电脑，Galaxy note，galaxy s和HTC Sensation上运行，没有任何错误。但是我只在具有Android 2.2的HTC Desire HD A9191设备上出现以下错误。

为什么？

Answer 1

我们曾经在Desire HD上遇到过Gson的问题，因为我们的应用程序中嵌入的gson.jar文件并没有在运行时使用，而是HTC附带ROM的过时版本。我想，你有类似的问题。一种可能的解决方法可能是使用jarjar（http://code.google.com/p/jarjar/）来确保您的应用程序使用您的gson jar。

修改这里最常见的问题是：GSON + HTC Desire: Conflict. Possible solution jarjar.jar causes error

仅在设备HTC Desire HD A9191上出现Gson错误
