A problem occurred configuring project ':video_compress'.

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.

 If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

Hey, did you get solution?

[temirfe]

For now it seems that package doesn't work with AGP and Gradle 8, I downgraded agp to 7.4.2 and gradle to 7.5

in my case if am using gradle 7.4 error unsupported class file major version 64
else using gradle 8.1.1 error package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

@danialali52 To fix this do this :
it is because the namespace property is not specified, you will have to go to in mac :
/Users/(your_username)/.pub-cache/hosted/pub.dev/video_compress(or whatever package has error)/ android/ build.gradle.

And in the build.gradle file you will see :

• group ' some package name (this is the namespace) ' .

• Just copy the group value and go to android block and write :

• namespace " group value i.e namespace value".

• Done , Save the file and re-run , it will work now.

• If you encounter the same problem in any other package, do the same thing.

• Eg. I have attached a screenshot for a package build.gradle file :
