title: Using a Library Project
body: <p>I have a android application, say 'OldApp', which uses some native methods within itself, and I have to use it as a library for a new app, say 'NewApp'.</p>
  
  <p>This is the first time i work with this request and i have a doubt:</p>
  
  <p>the OldApp has some classes, and one of these is the JNI Wrapper and contains the native methods, for example:</p>
  
  <pre><code>public class LibOldApp {
  
     private static native int method1();
     ....
     ....
  }
  </code></pre>
  
  <p>Can i use all the classes/methods of the OldApp or only the wrapper, and native methods?</p>
  
  <p>thank you..</p>
