No.

So now

  • wait for the Pre-launch report (maybe 1-2 hours) and
  • if you then do not see any errors / warnings / issues
  • download the APK from the Play Developer console and
  • test this APK on your test devices.
  • After that (if everything looks fine) release the app as a production version.
