title: Android studio create .jar file instead of .aar file
body: <p>Hi I followed android documentation to create a library. But my problem is whenever I run the project means it is creating .aar file. I google it and found <a href="https://stackoverflow.com/questions/21417419/how-to-convert-aar-to-jar">How to convert AAR to JAR</a>
  this. I'm using iZip Unarchiver. But it is not extracting the .aar file. 
  But they accepted that answer. Can any one know how to extract .jar from .aar. Thank you.</p>
