解决这个我按照这些步骤

:Remove all Android Library projects and external jars from the build path. 
:Place all external .jars in libs folder, the ADT should now place them under ' Android Dependencies'. 
:Re-import all your previous Android Library projects the normal way. 

后，它显示com.google.api不能得到解决，但我添加了所有相关的jar文件库已经

因此，您的图书馆com.apprevelations.daaku加载好，但你看到关于谷歌API的错误。 也许你只是错过了项目清洁。

Eclipse -> Project -> Clean... 

你还可以尝试：

Android Application -> Properties -> Android -> Google APIS(4.2.2 or any) -> Apply -> ok 
Eclipse -> Project -> Clean...
