I've added zxing core prebuilt jar to my Android studio project. However, I am unable to access any of the classes. If I do com.google.zxing it doesn't recognize the import nor any other package. The error I receive is Cannot resolve symbol zxing. I did add it as a dependency to my project, so I'm not sure what is going on. zxing core is added as another module.
The first time I tried this, I imported the core files with javadoc. I'm not sure if this was the problem. I tried again importing the core jar, except this time without the javadocs. I am able to access the classes now.
