Select 10 Existing Android Code Into Workspace and 9 click Next.
Browse to the SDK installation 8 directory and then to the Support Library 7 folder. /extras/android/support/v7/appcompat/.
Click 6 Finish to import the project. For the v7 5 appcompat project, you should now see a 4 new project titled android-support-v7-appcompat.
