title: Unity3D with multiple jars (android jar + pure java lib)
body: <p>I'm new to Unity3D and I have some projects already done with Java which need to be included in my Unity3D project.</p>
  
  <p>I want to add multiple jars into Unity3D project but it looks like jars are not have any dependency between them when they are running in Unity project.</p>
  
  <p>For this,</p>
  
  <ul>
  <li><p>I tried to add all the jars related in Assets/Plugins/Android folder (Multiple some pure java jar files in the folder with an Android jar to invoke the methods of jars)</p></li>
  <li><p>I tried to make only one jar file (By creating an Android project with all the jars included)</p></li>
  </ul>
  
  <p>With these 2 methods, I can build my project as Android based, but they showed errors say related library is not exist</p>
  
  <p>Is there any way I can use multiple jar library into Unity3D project with dependency to other jars?</p>
  
  <p>In other words, I want this structure</p>
  
  <p>| Main Project(Unity) | --dependency--> | Jar lib 1 | --dependency--> | Jar lib 2 |</p>
  
  <ul>
  <li>Jar lib 1: Library I need to call method directly</li>
  <li>Jar lib 2: A library which lib 1 uses</li>
  </ul>
