Gradle 8 support

[gohar-ali-coingaming]

hi!

I am trying to implement customer.io flutter sdk and found this issue regarding name space.

---

• What went wrong: Failed to query the value of property 'buildFlowServiceProperty'.

  Could not isolate value org.jetbrains.kotlin.gradle.plugin.statistics.BuildFlowService$Parameters_Decorated@1cd91fd7 of type BuildFlowService.Parameters A problem occurred configuring project ':customer_io'. 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.

• 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. Get more help at https://help.gradle.org.

Fix is fairly simple, adding name space in the build.gradle should help. https://developer.android.com/build/configure-app-module#set-namespace

Hi @gohar-ali-coingaming,

Thanks for reaching out and opening the issue.

The issue is related with the Gradle version you are using (8.x) to build the app, which still needs to be fully supported by our Flutter SDK.

Our recommendations to solve the issue on your end are:

1- Downgrade Gradle to a 7.x version and try building again 2- Override and set the namespace dynamically as suggested in this SO Answer

Let us know how exploring the options go please and we can assist you forward from there as needed

Best, Hernan

thanks @halbano,

• Downgrade Gradle to a 7.x version is not an option for us, as we have spent a lot time upgrading it and we put effort to keep our project as updated as possible.
• I am gonna use the override subprojects namespace, however, customer-io is the only project with this issue. And would be great if we can avoid this kind of patches from our code.

Looking forward to updated SDK with latest gradle version support soon 💪

Any updates on this issue ? Downgrade Gradle to a 7.x version is also not an option for us

@levibostian When is support for version 8 planned?

Hey @Korefey, thank you for reaching out. Happy to inform it's part of current development cycle and while I can't give any timeline, I assure you it's been worked and we plan to roll out Gradle 8 support as well R8 full mode support that is enabled by default in Gradle 8.
