问题
I just started using Dagger Hilt for dependency injection on Android and I get a warning on Android Studio saying 'ApplicationComponent' is deprecated. Deprecated in Java.
I didn't find anything related to this warning while Googling, is it actually deprecated or is it safe to use?
I also noticed on Dagger's website that they don't mention it anywhere in the "Migrating to Hilt" guide and they use @InstallIn(SingletonComponent::class) which seems to be working but I have no idea why.
回答1:
ApplicationComponent being renamed to SingletonComponent, to allow usage of Hilt in non-Android Gradle modules link
回答2:
Is ApplicationComponent deprecated?
Yes, it is deprecated.
Instead of ApplicationComponent, you can use SingletonComponent.
This is an Hilt component for singleton bindings
