title: How to run jar file within Android Studio?
body: <p>I have a jar file of java classes. I want to create an apk of my jar file. I know how to add libs folder into my android project, but I do not know how to make connections. I need to refer to my jar file in MainActivity.java, as well as in AndroidManifest.xml? What should I write in these two files?
  Indeed, I spent good time googling for an answer and reading posts on stackoverflow and others, but I did not find the specific answer for my question.</p>
  
  <p>I hope you can help me.
