title: Duplicate resources com_crashlytics_export_strings.xml in Android during build process after adding Crashlytics
body: <p>I have added latest version of <code>react-native-firebase</code> <code>crashlytics</code> 8.1.1 and I'm getting an error in Android during the build:</p>
  <blockquote>
  <p>Duplicate resources in com_crashlytics_export_strings.xml</p>
  </blockquote>
  <p>Any ideas how is possible to fix this issue? This file was automatically generated by Crashlytics.</p>

  <p>P.S: if delete <code>com_crashlytics_export_strings.xml</code> it would be possible to make app build. However, I'm not sure how important that file is. Will Crashlytics work correctly if there wouldn't be this file in the project?</p>
