title: java.lang.NoClassDefFoundError: org.apache.commons.lang3.ArrayUtils
body: <p>I have an Android application, which is working fine. The application have two Java libraries. I installed the newest versions of Eclipse and the Android SDK package on another computer, and I imported in it the same application from the server, but when I run it, the program can't find the java libraries. I tried to remove them from "Build Path Property" and I added them again, but it still gives me this error: </p>
  
  <pre><code>  java.lang.NoClassDefFoundError: org.apache.commons.lang3.ArrayUtils
  </code></pre>

  <p>Thanks in advance.</p>
