title: Adding .java library to an Android project
body: <p>I have a library I want to add to my Android Application. But the problem is that the library is separated into <code>.java</code> files. Now I have tried to add a module to do the job but it does not work. My problem is I do not know how to add a bunch of <code>.java</code> files to my Android project to use throughout my app. I am new to Android dev and I have looked around but cannot find a clear explanation of how to add my type of library to an Android project.<img src="https://i.stack.imgur.com/QICJ5.png" alt="enter image description here"></p>
