Migrate from Hilt (Dagger2) to Koin for Dependency Injection

[shubham0204]

Due to issues #4 originating from Hilt, the project is now being migrated to Koin. Koin is a light-weight DI framework written in Kotlin, and has been adopted by the developer community widely.

This code compiles however once run, the following error happens where the generated files are not in the expected directory structure?

It might be that installing Oboe 1.4.3 might solve the issue of not finding the symbol in the error output

[shubham0204]

This is a known issue https://github.com/shubham0204/Sentence-Embeddings-Android/issues/1 on the Sentence-Embeddings-Android repository. The library cannot be used in apps that run on x86-64 Android (emulators).

I suggest that you try running the app on an Android mobile device (ARM-based).

yep. the Docs-QA pops up when an android is connected. Well done and thanks
