集成 Spreadsheets API 的 Android 应用程序

Question

我的应用程序从用户帐户访问电子表格，之前通过 Google Plus 登录按钮进行身份验证，在 Google API 控制台中选择了所有适当的范围和凭据，并且我有一个登录的 GoogleApiClient，我可以使用它访问用户资料信息。

当我尝试初始化 SpreadSheetService 对象时:

SpreadsheetService service = new SpreadsheetService("SpreadSheetImport-v1");

我得到与类 com.google.common.collect.Maps 相关的异常:

我的 IDE 是 Eclipse ADT，我已经按照 Google Sheets Api 导入了谷歌 API 库，无论是使用那里描述的这种方法还是添加外部 jar ，都获得了相同的结果。

有什么想法吗？

Answer 1

找到解决方案...这还需要添加 google Guava图书馆。还有一个用于 eclipse 的插件。
