Build Fails: Namespace Not Specified in Module ‘:livechatt’

 When trying to build the project, the build fails due to a missing namespace declaration in the :livechatt module’s build configuration. This issue prevents the Gradle assembleRelease task from completing successfully.

Environment
• Android Gradle Plugin version: [Specify AGP version]
• Gradle version: [Specify Gradle version]
• Kotlin version: [Specify if applicable]
• OS: [macOS/Linux/Windows, and version]

Steps to Reproduce
1. Clone the repository.
2. Run ./gradlew assembleRelease or try to build the project via Android Studio.
3. Build fails with the error below.

```
> Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
> Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.
```

FIX:
```
android {
namespace 'com.example.livechatt' // replace with the actual package name
}
```

Inspect the :livechatt module's build configuration, then run ./gradlew assembleRelease to reproduce the missing-namespace failure. Confirm the module's actual package name and add the namespace declaration so the release assemble task completes successfully.
