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

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 Files\adt-bundle-windows-x86-20131030\sdk\extras\android\support\v7\appcompat. 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????

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 Files\adt-bundle-windows-x86-20131030\sdk\extras\android\support\v7\appcompat, then you have to move your own project somewhere on drive C:\ (e.g. C:\Users\User\workspace)

this work for me

Do as below:

Go to File -->Import -->Import the library project into your workspace(select the project exists here C:\Program Files\adt-bundle-windows-x86-20131030\sdk\extras\android\support\v7\appcompat).

Then Right Click on your project-->Select Android --> Add-->Select the library project you have imported.

don't forget to checkmark the library project in Project-->Right Click-->Properties-->Java Build Path--->Order and Export

  • Remove all of your library projects
  • Do a clean of the project with the dependecies
  • Add the problematic library again
  • Add all of the other libraries
