title: how to import library and modules to android studio properly
body: <p>I want to use this library (<a href="https://github.com/ikimuhendis/LDrawer" rel="nofollow">https://github.com/ikimuhendis/LDrawer</a>) in my project. but when i import it as new modules i can't see where it is? and then some gradle error occur like this:</p>
  
  <p>cant find runProguard</p>
  
  <p>and then i replaced this with minifyEnabled
  then this error occur "change gradle version Error:Library projects cannot set applicationId. applicationId is set to in default config"</p>
  
  <p>then i clear applicationId but i still have this error!
  i can't understand what is sample folder, library folder, or root folder in project! i have to import which one?!</p>
  
  <p>I import sample project and root of this project with import new project but i have errors! newly i migrate to android studio from eclipse bcz many  open source project that using android studio.I guess all of my question because i can't understand android studio structure properly!  </p>
