Q :

How to resolve the error “No resource found that matches the given name” when adding library v7 AppCompat in Eclipse?

Ans :

You should add that support library to your project. To add:

Right click on project, then go to :

properties > Java Build Path > Libraries

here Add External JARs...

add android-support-v7-appcompat.jar (path/to/sdk/extras\android\support\v7\appcompat\libs)

Additionally you also have to copy that jar to libs folder of your project, if it is not there automatically.

and you should use the @style/Theme.AppCompat theme for your application for support-v7 to be working
