The error 'app:lintVitalRelease' occurs when the Android Lint tool detects issues in your APK that prevent it from being signed with a release key. This issue affects developers who have not properly configured their build variants for release builds, leading to an inability to upload debuggable APKs on Google Play.

This error can be frustrating as it prevents users from installing and using the app, and requires additional troubleshooting to resolve. In this guide, we will walk you through the steps to fix this issue and successfully generate a signed APK.

💡 Why You Are Getting This Error

The primary reason for this error is that the build variant of your module has not been set to release. When building in debug mode, Android Lint checks for issues that would prevent the app from being signed with a release key, which includes the 'app:lintVitalRelease' check.
Another possible cause is that there are still debugging statements or variables in your code that are causing the Lint tool to flag issues.
