[help] Android build error

[victor-nerdunited]

• [x] I have read the README
• [x] I have done the setup for Android
• [] I have done the setup for iOS
• [] I have ran the sample app and it does not work there

Version

Technology	Version
Workmanager version	0.5.1
Xcode version	NA
Swift version	NA
iOS deployment target	NA
Flutter SDK version	>=2.18.0 <4.0.0

Describe the error The example app builds and runs. I created a new flutter app based off of flutter fire and added workmanager to it. The app builds and runs without workmanager, but if I add workmanager it wont build with this error:

$ flutter run
Using hardware rendering with device sdk gphone64 x86 64. If you notice graphics artifacts, consider enabling software rendering with "--enable-software-rendering".
Launching lib\main.dart on sdk gphone64 x86 64 in debug mode...

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':workmanager'.
> 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.gradle file like so:

     android {
         namespace 'com.example.namespace'
     }

     If the package attribute is specified in the source AndroidManifest.xml, it can be migrated automatically to the namespace value in the build.gradle file using the AGP Upgrade Assistant; please refer to https://developer.android.com/studio/build/agp-upgrade-assistant for more information.

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

I mentioned the example app runs before, but if I remove the relative reference to the workmanager plugin and use pub.dev then it fails with the same error as my app.

Please try again with the new version 0.5.2.
