推荐答案

你应该做的是，

1.  Select your android project
2.  press ctrl +alt + shift + S
3.  Select SDK from the project settings
4.  Check the files under the class path tab
5.  There must be android.jar ,res ,annotations.jar
Probably there should be missed one or several files in step 5.
Then,
6.  Go to Android SDK home path field and add your SDK folder again
files  even though  you have all the jars and still  you are getting the error ,then remove all the jars from the class path and add them again ( like in step 6).
7.  Build menu -Rebuild  your  project.

现在你的错误应该消失。

Now your errors should disappear.
