Dagger 2, Providing Application Context in Module

Question

Im pretty new in Android development and newer in DI. I am using Kotlin on a personal project where I am experimenting with Dagger 2. I managed to set it up for a util class

You can try modifying your App module like this.

@Module
class ApplicationModule(private val application: Application) {

    @Provides
    @Singleton
    fun provideContext(): Context {
        return application.applicationContext
    }

    @Provides
    @Singleton
    fun provideSharedPreferences(context: Context): SharedPreferences {
        return context.getSharedPreferences(PREF_FILE_NAME, Context.MODE_PRIVATE)
    }
}

Then you can build the dagger component like this from your Application class.

val appComponent = DaggerAppComponent.builder()
                .applicationModule(ApplicationModule(this))
                .build()

Inject values in presenter like this.

application.appComponent.inject(this)
