Build Error with AGP 8.0+: Namespace not specified

[aymanalhalali]

Hello,

I've recently updated my project's Flutter version and the Android Gradle Plugin to the latest version, and after doing so, I encountered a build issue with the insta_assets_picker package. The error occurs when trying to configure the project:

A problem occurred configuring project ':insta_assets_picker'.

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.

It seems that the newer version of AGP requires a namespace declaration in the module's build.gradle file. Here is the environment in which the error occurred:

• Flutter Version: 3.16.5
• Dart Version: 3.2.3
• Android Gradle Plugin Version: 8.1.2
• insta_assets_picker Version: 2.3.0-dev.1

According to the Android documentation on namespaces, this is a new requirement starting with AGP 8.0.

Could you please look into this issue? If it's a matter of updating the package to support the latest AGP requirements, an update would be greatly appreciated. I rely on insta_assets_picker for my project, and this build issue is a blocker for me.

Thank you for your work on this package and for any assistance you can provide.

Best regards, Ayman

Hum, as you can see in the repository there is no android configuration in this package, so I am not sure how this issue could occurs from this package. Did you fixed your issue ?

I was only able to solve it by using previous versions rather than upgrading to 8.0:

• ext.kotlin_version = '1.8.0'

• classpath 'com.android.tools.build:gradle:7.2.2'

• distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-all.zip

Hey @LeGoffMael , I'm having the same problem. The incriminated library should be insta_assets_crop, which is a direct dependency of insta_assets_picker.

I can open an issue here if you want

[inludese]

Simply add this to top level build.gradle into allprojects section

subprojects {
        afterEvaluate { project ->
            if (project.hasProperty('android')) {
                project.android {
                    if (namespace == null) {
                        namespace project.group
                    }
                }
            }
        }
    }

@inludese but this is not a fix, is a workaround

[LeGoffMael]

Thank you so much for your insights @AngeloAvv, I released a new insta_assets_crop version with the fix. This issue should be fixed in the new 2.3.1 version !
