After searching i found that the latest revision (#12 from Feb 2013) of the Android Support Library doesn't contain some classes that it should have (FragmentTabHost, and a few more) 搜索后，我发现Android支持库的最新版本（2013年2月＃12）不包含它应该具有的某些类（FragmentTabHost等）

tried to delete and download again, and again it didn't contain the classes it should, 尝试再次删除并下载，但又没有包含应有的类，

I found this link to the previous release (if you want a different release you can just change the number - 01,02...,09,10,11,12) 我发现此链接指向以前的发行版（如果您要使用其他发行版，则可以更改数字-01,02 ...，09,10,11,12）

I replaced the support folder, copied the new (older) jar , and that solved all the problems. 我替换了support文件夹，复制了新的（较旧的）jar，这解决了所有问题。
