title: Skobbler Android SDK: How to add more language files
body: <p>I am trying to use a different audio advice language for navigation, however when I set the <code>SKAdvisorSettings</code> to use a new language (en_us) it said it could not find the file. After some research I found this link saying I needed to add the sound files to the <code>.zip</code> file:</p>
  
  <p><a href="http://forum.skobbler.com/showthread.php/7250-Language-files-for-2-5-0-and-2-5-1" rel="nofollow noreferrer">http://forum.skobbler.com/showthread.php/7250-Language-files-for-2-5-0-and-2-5-1</a></p>
  
  <p>However when I unzip, add the file, and zip again (using Mac, right click, compress), the map fails to initialize and the only error shown is <code>E/SKPrepareMapTextureThread: Shaders or Common files not found</code></p>
  
  <p>Maybe I do not know how to add files to a <code>.zip</code> without otherwise affecting it, or I am missing how I am supposed to add the sound files to the project completely.</p>
  
  <p>tl;dr: I want to be able to add more sound files to the navigation advice.</p>
  
  <p>Thanks</p>
