title: Errors while running Vuforia samples in Android
body: <p>I am using ADT 23.0.I have installed NDK and set the environment variable.Set variable in class path variables and pointed to vuforia SDK path. Once I deploy the app and choose a sample then click start, It comes back to the previous page.. the camera is not opened.</p>
  
  <p>I got the following errors in my logcat:</p>
  
  <pre><code>SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length
  
   The library libVuforia.so could not be loaded
  </code></pre>
  
  <p>According one of the forum post's answer I have edited the XML file and given the absolute path ,</p>
  
  <pre><code>&lt;copy overwrite="true" todir="libs/armeabi-v7a"&gt;
              &lt;fileset dir="E:\vuforia-sdk-android-3-0-9\build\lib\armeabi-v7a"/&gt;
