kotlin - Hilt using in android library

Question

I would like to try Hilt DI in the android library.

It is a dependency on another project, with its own submodule. The very first problem I've encountered is the requirement of marking Application with @HiltAndroidApp. Now I do not have anything that extends Application in my library ofc but would like to utilize Hilt and its predefined components.

Is it possible or should I go with Dagger only in such a case? I've found a solution for Dagger, where library dependency injection is made totally independently (the client is unaware of the library's DI): Dagger solution, would love to hear any opinion on that, maybe someone already put a great effort into that issue and can share his insights.

Answer 1

If you're trying to include Hilt in an android library, then you should expect the android app (client of your library) to mark its Application with @HiltAndroidApp.

You should include your whole setup (entry points, modules, dependencies, ... whatever you want to have in your library) in the library module, and make the requirement for the client of the library to use the @HiltAndroidApp to use your library correctly.
