DriveChain Android Services for AndroidInjectors

This component provides Dagger2 modules for services that already exist within Android, designed to be used with the new AndroidInjectors in Dagger 2.10+. Note that using this and the other Android Services module included in DriveChain is not supported and probably impossible. This module relies on you binding an application into the graph with a Component.Builder and relies on the Activity instance bound into the graph by using a DispatchingAndroidInjector<Activity>.

Installation

Add the dependency to your build.gradle file

compile "com.github.InkApplications.DriveChain:android-services:2.+"

Any of the Modules can be included in your application’s Dagger component:

    @Component(modules = arrayOf(AndroidApplicationModule::class))
    interface MyApplicationComponent {}

Add your application to the graph by adding a builder with a @BindsInstance to your component:

    @Component(modules = arrayOf(AndroidApplicationModule::class))
    interface MyApplicationComponent {
        @Component.Builder interface Builder {
            @BindsInstance fun application(app: Application): AppComponent.Builder
            fun build(): AppComponent
        }
    }

Then build the component in your Application class:

    DaggerAppComponent
        .builder()
        .application(this)
        .build()
        .inject(this)

If the module requires the activity, it must be marked as an @ActivityScope:

    @Module abstract class ActivityBuilderModule {
        @ActivityScope @ContributesAndroidInjector(modules = [AndroidCompatActivityModule::class]) abstract fun myActivity() : MyActivity
    }

Available Modules

There are three primary modules provided by this library:

AndroidApplicationModule

This module provides dagger injections for the services that lurk within the Android Application class.

AndroidSystemServiceModule

This module provides dagger injections for the services that are hidden behind the Context.getSystemService(String) factory. All the services will be type-safe when they are injected with this module. No more casting!

AndroidCompatActivityModule

This module provides injections for the services inside the Activity class. These require an instance of the Support Library’s AppCompatActivity and are limited to the ActivityScope.

Usage

Once the modules are installed, you can start requiring standard Android services in your classes like any other injection:

class Foo @Inject constructor(
    private val resources: Resources,
    private val notificationManager: NotificationManager
)
