* What went wrong: A problem occurred configuring project ':vitamio'. > Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl. > Namespace not specified. Please specify a namespace in the module's build.gradl

It seems that you are encountering an issue with configuring the project ':vitamio' in Android Studio. Specifically, the problem is related to creating an instance of type 'com.android.build.api.variant.impl.LibraryVariantBuilderImpl' and the namespace not being specified in the module's build.gradle file.

To resolve this issue, you can try the following steps:

1. Open the build.gradle file of the ':vitamio' module.
2. Look for the android block and ensure that the namespace is specified. It should look something like this:

   android {
       namespace "your.namespace.here"
       // other configuration options
   }

Make sure to replace "your.namespace.here" with the appropriate namespace for your project.

3. Sync your project with the Gradle files to apply the changes.

If the issue persists, it could be caused by other factors specific to your project setup. In that case, providing more details about your project structure and the steps you have taken so far to configure it would help in troubleshooting the problem further.
