title: Android Telegram App --> java.lang.UnsatisfiedLinkError: No implementation found for void
body: <p>Unfortunally a similar question was removed at Stackoverflow some weeks ago, I must make a new question.</p>
  
  <p>Im trying to build an own Telegram app for android via source @ <a href="https://github.com/DrKLO/Telegram">https://github.com/DrKLO/Telegram</a></p>
  
  <p>I can not get it to work, it stops on startup with the following error, any ideas on where to start, Im quite new to Android Studio.</p>
