These are the errors in my picture. I do not know how to work with it, and I have tried to change the library, but without success.
Please help me if you can.
This seems to be more of an issue with your eclipse work-space or the way you have created the project. You should check your build path and make sure all the libraries are present.
Also in your left pane, i don't see any Reference Libraries which would list down all the libraries in use.
