android - Android 应用程序中的 ExceptionInInitializerError？

Question

在我的 Android 应用程序中，WebView Activity 类有以下行，

webView.addJavascriptInterface(new JSInterface(this), "Android");   

在 JSInterface 类中，我正在初始化 Google“SpreadSheetService”，如下所示，

import com.google.gdata.client.spreadsheet.SpreadsheetService;

--- some more imports ---


public class JSInterface {
    Context mContext;

    public SpreadsheetService service;

    /** Instantiate the interface and set the context */
    JSInterface(Context c) {
        mContext = c;
        service = new SpreadsheetService("List Demo");
    }

    ------- some more code -----

当我运行应用程序时，出现以下异常，

01-19 21:38:00.652: E/AndroidRuntime(4085): java.lang.ExceptionInInitializerError

它有下面的轨迹

我搜索了谷歌，但没有得到任何解决方案。知道为什么我会收到这个异常吗？

彼得

Based on this documentation抛出 ExceptionInInitializerError 以指示在评估静态初始化程序或静态变量的初始化程序期间发生异常。检查您的代码是否有任何静态初始化逻辑。
