title: React native android application has stopped
body: <p>I've stuck with an android version of an application (this one with "Welcome to React Native!" text). After this, I did exact steps as a documentation says. After build android version of this application, i copied signed version of APK file on my device and install it - when i'm trying to launch it then i receiving message "<strong>Unfortunately, FirstProject has stopped</strong>". Debug version of this application working fine. I've spent almost a week trying to run this, and i didn't find any solution. Do any one have any idea what i'm doing wrong?</p>
  
  <p>Regards</p>
