ExceptionInInitializerError in Android app?

问题

In my Android app the WebView activity class has following line,

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

And in JSInterface class, I'm initializing Google "SpreadSheetService" like below,

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 -----

When I run the application I'm getting the following exception,

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

which has the below trace

Based on this documentation An ExceptionInInitializerError is thrown to indicate that an exception occurred during evaluation of a static initializer or the initializer for a static variable. Check your code has any static initialization logic.
