How to connect my application with a local server in android

I'm a beginner, and I need to find a way to connect a local server to an android app. I hope you can provide me with a book to teach me hoe to do it. I have searched all over google, but couldn't find any. Thanks in advance.

Please learn basic skills. Tutorials "step by step" may leave a gap in your knowledge.
