what I have tried updated latest version of room and dagger hilt in app.gradle dependencies tried following link error: cannot find symbol @dagger.hilt.InstallIn(value = {ApplicationComponent.class}) all other stackoverflow links as well I have changed jdk version from android studio it did not help I want to know where I am making mistake
I solved problem by adding InstallIn annotation to repoModule and by removing following implementation "androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03" hilt dependcy
