There is no deobfuscation file associated with this App Bundle

I have just encountered the following message after uploading my app: There is no deobfuscation file associated with this App Bundle. If you use obfuscated code (R8/proguard), uploading a deobfuscation file will make crashes and ANRs easier to analyze and debug. Using R8/proguard can help reduce app size

Can someone kindly be of assistance?

You don’t mention in your question, but I’m assuming you are getting this message from the Android Play Store, not from VoltBuilder itself.

Is it a warning or an error?

If it’s just a warning, it’s likely your app will still be approved.

Yes, this would be a warning and not an error from Google Play Store upon uploading. You should be able to continue and apps will still be approved.

Thank you!
