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

编辑：我也在上面报告的日志之前发现了这个
02-26 16:51:57.780: W/dalvikvm(1230): Unable to resolve superclass of Lcom/google/api/services/utenteendpoint/Utenteendpoint$Builder; (20) 02-26 16:51:57.780: W/dalvikvm(1230): Link of class 'Lcom/google/api/services/utenteendpoint/Utenteendpoint$Builder;' failed
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。
感谢Raffo在我之前的post中找到了拼写错误
