You should import as new module for your android project follow the below steps to add as a new module

 1.Go to file -> New - > Import Module

and select your zxcvbn library location path and click finish. This will add a new module to your existing android project.

Then you should add a new module i,e your ( zxcvbn library ) to your project dependency to do that

 2.Click project structure options - > dependency select your  zxcvbn library and click ok and synch project

Now your java library included in your android project
