Hi @longquangpham90, thanks for the report!

I can see see that you're encountering an "Error class: unknown class" error in the rendered HTML. However, I can't see see any obvious problem. I'd like to help, but I'd need more info. I'm not familiar with Android development. Can you share the project, or an example? How can I reproduce it? What versions of Gradle/Kotlin/Android/Dokkatoo are you using? What's the project structure? How many subprojects have you got? What configuration have you used?

Hi @aSemy
I have invite project example
Could you help me check project it
My project setup with multi module, we want to have document the same folder module project and by pass issue Error class: unknown class
Many thanks!

Thanks! I can't see anything wrong.

I can see that it's quite a large project, and I don't have time to investigate something of this size really. Also, because the project is quite big I can't download it, for security reasons.

I did have a look through though, and I have some notes:

• I couldn't find the source code for the FragmentSplashBinding class (GitHub doesn't let you search for code in branches, so maybe I missed it). Are you sure such a class exists?
• I can see that the project uses script plugins. That might interfere with Dokka discovering information from AGP. I recommend using convention plugins instead.

Thanks @aSemy
"FragmentSplashBinding" is a class generated by the Android Data Binding Library when you use Data Binding in your Android app. It is generated from a layout XML file named "fragment_splash.xml" in this case. This class contains references to UI components in the layout XML

Ahh okay. So if it's generated, you might need to tell Dokkatoo to use the generated sources. Those generated files are used during compilation, so Dokkatoo should detected them automatically, but I guess that's not the case...

I'd really like to fix it, but I'm really not an Android dev. Could you help me out and create a smaller reproducer? Does it need to be a multi-module project, or does it also happen in a single module project?

To fix it in the meantime, you could try telling Dokkatoo about the source directory. Something like this:

// build.gradle.kts

// ...

dokkatoo {
    dokkatooSourceSets.named("main") {
        sourceRoots.from( /* TODO tasks.named("nameOfTaskThatGeneratesSources") */ )
    }
}
