Fabric proguard rules
<p>I have found on fabric page following note </p>

<blockquote>
  <p>For Fabric to properly de-obfuscate your crash reports, you need to
  remove this line from your ProGuard config:</p>
  
  <p>-printmapping mapping.txt</p>
</blockquote>

<p>Can anyone clear for me this thing. How I will reobfuscate crash logs by myself if I remove this line?</p>
