create android project and android-support-v7-appcompat is not included in lib(eclipse)
Question: I fixed the problem. I used the workspace which was given by a python
professor. I guess some sets do not match. After changing workspace, it works.
Thank all you guys answer.

When i create a new android project, i ask eclipse create the activity for me.
the code need to be imported v7, but there is not v7 in the lib. The error
message shows up and stop the creating process. Anyone know how to fix it?（And
i want to fix it in one time. i dont want it show up every time i create new
project）(also if i cant fix it, eclipse cannot finish creating process,it
means there are some unknown file have not be created before the error.this is
the biggest problem)

Answer: This is because you need to reference support v7 in your project.missing
library. So you can solve this problem by following steps

    
    
    1.  File->Import (android-sdk\extras\android\support\v7). Choose "appcompat"
    2.  Project-> properties->Android. In the section library "Add" and choose "appCompat"
    

That's it. I hope this answer is helpful to you friend :)
