android - Dagger 2 scopes in a class -

so have class injectable:

@singleton public class friendmessagelistimpl {      @inject riotrostermanager riotrostermanager;      @singleton     @inject     public friendmessagelistimpl() {     } } 

my component injected in application class:

appcomponent = daggerappcomponent.builder()                 .appmodule(new appmodule(this))                 .build(); 

---

@singleton @component(         modules = {                 appmodule.class         } ) public interface appcomponent {       /**      * core      */     void inject(...); } 

the objected injected first time background service running.

the objects should singleton application scope, mean 1 instance long service lives. i'm not sure if case, reason singleton seems not have application scope. there way can force it? , scope supposed have considering code?

from understood, have 1 component created in application class, , altought object injected thru constructor, shares same scope component. wrong?

from description seems background service running after app first started application object stays live (until service stopped , activities finished). seems pretty fine, not need create graph again, existing instance.
