Question

I have a very annoying problem, when I try to open an imported project with my version of Eclipse, it tells me that I can't do it unless I download the version 21 of something. Then it opens my SDK Manager and when I want to install the new packages to update my version, it's just impossible even after having accepted the terms and conditions.

Any help is welcome! Thanks in advance.
