android - how can I inject a dependency in a method? -

i'm beginner dependency injection.. dagger 2. i'm trying figure out if/how can this:

@inject public void somemethodname(int someinteger, someobject dependency){  // dependency.  } 

or need put dependency in class var? appreciated. in case variable someinteger not dependency, being added caller... matter?

can call this:

this.somemethodname(5);  

android studio not above calling method (i'm assuming because i'm doing wrong)

1. you need create component annotated @component.
2. the component accepts module provides dependencies.
3. every component's name create starts dagger prefix, e.g. mycomponent.

let's @ following example:

    @singleton     @component(modules = demoapplicationmodule.class)     public interface applicationcomponent {         void inject(demoapplication application);     } 

we created applicationcomponent single injection method. we're saying want inject dependencies in demoapplication.

moreover, in @component annotations specify module provision methods.

this our module looks like:

@module public class demoapplicationmodule {    private final application application;     public demoapplicationmodule(application application) {        this.application = application;     }    @provides @singleton someintegerhandler provideintegerhandler() {        return new mysomeintegerhandlerimpl();   }  } 

what we're saying creating demoapplicationmodule module can provide desired dependencies in injection place specified our component.

 public class demoapplication extends application {    private applicationcomponent applicationcomponent;     @inject someintegerhandler handler;     @override public void oncreate() {      super.oncreate();      applicationcomponent = daggerapplicationcomponent.builder()          .demoapplicationmodule(new demoapplicationmodule(this))          .build();      applicationcomponent.inject(this);      handler.somemethodname(5);    }   } 

see documentation kind of dependencies can obtain. additionally obtaining raw instance can obtain provider, factory or lazy instance. http://google.github.io/dagger/api/latest/dagger/component.html

you can create scoped dependencis, lifecycles of depend on lifecycle of injection places, activities or fragments.

hope gave basic notion of dagger is.
