Solution 1
Your CoffeeMachine needs CoffeeMaker. And you have declared that Dagger will take care of providing that dependency to the CoffeeMachine by annotating the constructor with @Inject. But Dagger says:
CoffeeMaker cannot be provided without an @Provides-annotated method
Because you haven’t specified anywhere how CoffeeMaker object should be created. @Injecting SimpleMaker is not enough, because SimpleMaker != CoffeeMaker. So, you have to specify explicitly, that when Dagger wants CoffeeMaker then provide him SimpleMaker.
Change your module to this:
@Module
public class SimpleModule {
@Provides
Cooker providerCooker() {
return new Cooker("tom", "natie");
}
@Provides
CoffeeMaker provideCoffeeMaker(Cooker cooker) {
return new SimpleMaker(cooker);
}
}
