Getting NoClassDefFoundError after introducing AndroidEntryPoint about codelab-android-hilt

That might be the issue, try with api project(':api')

AGP doesn't give Hilt or Dagger enough information for the annotation processor so api needs to be used. This is currently under investigation and the team plans to improve it. Was implementation working with Dagger?

It seems like there's a problem with Dex files. Are you using multidex in your app? I assume that you have the LocationOwner as a transitive dependency of the app module, right? You're importing the other module as api and not implementation.

Thanks for your answer! This particular interface live in the API module and as far as I can see it is being imported with implementation project(':api'). We do use Multidex, but as minSdk is 21, we do not use support multidex.

[titovnick]

Yes, it works for dagger right now. Will try with 'api' and will write you back

Okay, with api project(':module') it works, but had to replace two or three in order to make it work. Why do you think it works for Dagger but not for Hilt? Thanks for your help, will never figure it out myself.

[manuelvicnt]

I'm surprised that it worked for Dagger, to be honest. Not sure if it wasn't picking up the right implementation or what but we've seen problems like it in the past with Dagger.

This is a known problem that the team is trying to fix as using api in these cases is not a good practice. Hope it gets fixed in the upcoming released. Stay tuned :)
