I have just included the android v7-appcompat library in my project.I have successfully added the jars to the build path and am now using the Theme.AppCompat theme.Now,I get this strange error:

[Dex Loader] Unable to execute dex: Multiple dex files define Landroid/support/v7/app/ActionBar$Callback; [2013-10-09 11:11:50 - DelTest2] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Landroid/support/v7/app/ActionBar$Callback;

EDIT

My project now contains three folders,each of which contains the android v7 appcompat:

+Android Private Libraries
+Android Dependencies
+Referenced Libraries

Which one of these libraries must I delete in order to make my project work?

Its showing error that your project contains multiple android-support-v4.jar.

One which is actually in your project and another is in the library which you have added in your project. Just remove the one library which you have added in your project. And then clean and run your application.

That's it.
