Can't Find Theme.AppCompat.Light 錯誤修改

You need to do next:

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

做一個項目總是報錯，Can't Find Theme.AppCompat.Light，郁悶半天，經過google找到此解決方案，記下。
