@InstallIn can only be used on @Module or @EntryPoint classes

Question

I am new at the dependency injection on Android. I am using Dagger-Hilt and in AppModule class that I generated for the DB providers I got an error and the project doesn't compile.

The error is @InstallIn can only be used on @Module or @EntryPoint classes This is my AppModule object. Where do I make mistake?

@Module
@InstallIn(ApplicationComponent::class)
object AppModule {

@Singleton
@Provides
fun provideAppDatabase(
    @ApplicationContext app: Context
) = Room.databaseBuilder(
    app,
    AppDatabase::class.java,
    "gelirkenal"
).build()

@Singleton
@Provides
fun provideItemDao(db: AppDatabase) = db.itemDao()
}

Answer 1

I set a import of Module as following:

import com.google.android.datatransport.runtime.dagger.Module

But the below is correct:

import dagger.Module

Answer 2

Change the following imports:

import com.google.android.datatransport.runtime.dagger.Module
import com.google.android.datatransport.runtime.dagger.Binds

To =>

import dagger.Module
import dagger.Binds
