body: <p>I get lastest code and step by step from <a href="https://wiki.videolan.org/AndroidCompile" rel="nofollow noreferrer">page</a></p>
  
  <pre><code>$ sh compile.sh -a x84
  You must define ANDROID_NDK, ANDROID_SDK before starting.
  They must point to your NDK and SDK directories.
  </code></pre>
  
  <p>I pointed NDK and SDK on the terminal on Gnome CentOS 7</p>
