title: 64 bit version issue in react-native android app by google play store

  <p><strong>In August 2019, Play store will require that new apps and app updates with native libraries provide 64-bit versions in addition to their 32-bit versions.</strong></p>

  <p><strong>Update</strong></p>
  
  <p>I added <code>x86_64</code> to my <code>build.gradle</code> and I now see the <code>x86_64</code> folder in the apk but I think some of the files are missing.</p>
  
  <p>Here is, how my <code>x86</code> folder looks like:</p>
