我试图做一个Android应用程序，需要与谷歌小号preadsheet API工作。我在这个新的，所以我开始与API的3版本：https://developers.google.com/google-apps/s$p$padsheets/

I'm trying to do an Android app that needs to work with Google spreadsheet API. I'm new in this, so I'm starting with the version 3 of the api: https://developers.google.com/google-apps/spreadsheets/

我跟所有的步骤，下载的所有jar文件到 LIB 在我的项目文件夹，子文件夹，然后我加入到构建路径在Eclipse中像往常一样。因此，虽然没有Java示例进行的Oauth 2.0，我只是想宣布：

I followed all the steps, downloaded all the jar files to lib subfolder in my project folder and then I added to the build path in Eclipse as usual. So although there is no Java example to perform Oauth 2.0, I just tried to declare:

SpreadsheetService service = new SpreadsheetService("v1");

但是当我仿效这种简单的线条它给了我一个错误：

but when I emulate this simple line it gives me an error:

java.lang.NoClassDefFoundError: com.google.gdata.client.spreadsheet.SpreadsheetService

我用所有包含在文档中的罐子和我有进口：

I'm using all the jars included in the documentation and I have the import:

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

但我完全失去了。我不知道自己还能做些什么刚刚启动，连接到谷歌API和带有S preadsheets工作。

but I am totally lost. I dont know what else to do just to start, connect to Google APIs and work with the spreadsheets.

推荐答案

感谢你这么这么多的蝎子！有用！！我一直在想这个时间过长。 确定这里是我的解决方案： 我开始一个新项目，其中包括这些罐子：

Thank you so so much Scorpion! It works!! I've been trying this for too long. Ok here is my solution: I started a new project and included these jars:

gdata-client-1.0
gdata-client-meta-1.0
gdata-core-1.0
gdata-spreadsheet-3.0
gdata-spreadsheet-meta-3.0
guava-13.0.1  

和我的code：

    SpreadsheetService spreadsheet= new SpreadsheetService("v1");
    spreadsheet.setProtocolVersion(SpreadsheetService.Versions.V3);

    try {
        spreadsheet.setUserCredentials("username", "password");
        URL metafeedUrl = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");
        SpreadsheetFeed feed = spreadsheet.getFeed(metafeedUrl, SpreadsheetFeed.class);

        List<SpreadsheetEntry> spreadsheets = feed.getEntries();
        for (SpreadsheetEntry service : spreadsheets) {             
            System.out.println(service.getTitle().getPlainText());
       }
    } catch (AuthenticationException e) {           
        e.printStackTrace();
    }

当然，

这是在不同的线程中执行不是在主线程。有没有Java文档的OAuth 2.0，但我会尝试，如果我不能做到这一点，我会问这里。 再次，非常感谢你，我希望能帮助你，当我工作的这段时间就好了。 ：）

of course this is executed in a different thread not in the main thread. There is no java documentation for OAuth 2.0 but I will try and if I can't do it I'll ask here. Again, thank you very much and I hope to help you when I work on this time enough. :)
