将Android应用程序连接到Google Cloud Endpoints时出错：无法找到课程

I have built an API with Google Cloud Endpoints and I am trying to connect to it writing an Android application. I followed the following tutorial:

我已经使用Google Cloud Endpoints构建了一个API，我正在尝试连接到它编写Android应用程序。我按照以下教程：

https://developers.google.com/appengine/docs/java/endpoints/consume_android

So, I added the content of the jar on my "src" folder, I copied the listed libraries to lib and I added the code. When I tried to start the application, it crashed with the following error:

所以，我在我的“src”文件夹中添加了jar的内容，我将列出的库复制到lib并添加了代码。当我尝试启动应用程序时，它崩溃了以下错误：

Do you know the possible cause of this error?

你知道这个错误的可能原因吗？

EDIT: I also found this before the log reported above

编辑：我也在上面报告的日志之前发现了这个

1 个解决方案

#1

Add the sources.jar file also to libs folder of your android project, just like the other jar files.

将sources.jar文件也添加到android项目的libs文件夹中，就像其他jar文件一样。

Thanks Raffo for finding the typo error in my earlier post

感谢Raffo在我之前的帖子中找到了拼写错误
