eclipse - Cannot add android.support.v7 to my project build path

Question

I am trying to add android-support-v7-appcompat to my project build path:

This is what I have done: Right-click on my own project -> build path -> configure build path -> choose Android on the left column and then click "Add". I choose "android-support-v7-appcompat". This name appears then in the right column of the table, on the left appears the path where the library is located: C:Program Filesadt-bundle-windows-x86-20131030sdkextrasandroidsupportv7appcompat. And it has a beautiful green check mark on the left!

I click Apply or Ok.

Then I go to this screen again, but though the path is still on the left in the table, there is a red cross on the left and a question mark, where "android-support-v7-appcompat" should have been. I have done exactly what is described in http://developer.android.com/tools/support-library/setup.html (title "Adding libraries with resources").

Has someone any idea????

Answer 1

the way how to preserve "green check mark" after reopen Properties window is putting your own project on the same letter drive, where is located project android-support-v7-appcompat

so if you have it located in C:Program Filesadt-bundle-windows-x86-20131030sdkextrasandroidsupportv7appcompat, then you have to move your own project somewhere on drive C: (e.g. C:UsersUserworkspace)

this work for me
