dagger-2

问题 How do I use the new AndroidInjector.inject and still be able to provide an Activity instance inside an Activity Module? The Dagger docs don`t make it clear how to archive this. The use case is the following: I have an Activity Module which provides a Presenter to my Activity, but the Presenter needs a reference to the Activity. I used to have something like @Inject Presenter presenter; public onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ((CustomApplication)

问题 What options do I have to make a single instance of all the models classes in an Android application?

问题 I am having trouble with the Dagger 2 dependency injection framework. I would like to create an EagerSingleton . I assume that dagger 2 creates lazy loaded singletons when I use the @Singleton annotation. How do I create EagerSingleton using the Dagger 2 framework ? 回答1: I solved this by creating an EagerModule which had a single provide method which returned Void . Everything I wanted created eagerly I specified as parameters to that method. Then I added a Void init() method to the Component

问题 All examples on how to combine ViewModel with dagger2 has been to use constructor injection on the ViewModelFactory. Like this: private final Map<Class<? extends ViewModel>, Provider<ViewModel>> providers; @Inject public ViewModelFactory(Map<Class<? extends ViewModel>, Provider<ViewModel>> providers) { this.providers = providers; } While the module could look something like this. @Module abstract class ViewModelModule { @SuppressWarnings("unused") @Binds @IntoMap @ViewModelKey(value =

问题 All the following are used with dagger 2.10 and dagger.android package. Say I have a class I'd like to inject in multiple activities. public class DemoSharedClass { Activity activity; @Inject public DemoSharedClass(Activity activity) { this.activity = activity; } } Then, using the latest Dagger APIs, my classes are defined as public class DemoActivity extends DaggerActivity { @Inject DemoSharedClass demoSharedClass; // ... } public class Demo2Activity extends DaggerActivity { @Inject

问题 With dagger-android one now can simply write the following and successfully inject the app's dependencies: @Module public abstract class MainActivityModule { @ContributesAndroidInjector abstract MainActivity contributesMainActivity(); } @Singleton @Component(modules = { AndroidSupportInjectionModule.class, AndroidInjectionModule.class, AppModule.class, MainActivityModule.class }) public interface ApplicationComponent { void inject(BaseApplication baseApplication); @Component.Builder interface

问题 I'm getting the error while trying to get the new Android dagger classes from Dagger v2.11 working in our project. I'm not exactly sure what the problem is, as I've taken into account the Android documentation over at https://google.github.io/dagger//android.html and still cannot get over this issue. Any ideas on what's wrong with this setup? MyApplication: public class MyApplication extends Application implements HasActivityInjector { @Inject AndroidInjector<Activity> androidInjector;

问题 I have a module to provide a Retrofit interface. @Module class NetModule(val base: String) { @Provides @Singleton fun provideOkHttpClient(): OkHttpClient { return OkHttpClient.Builder() .addInterceptor(object: Interceptor { override fun intercept(chain: Interceptor.Chain): Response { val request = chain.request() info("Request for ${request.url()}") return chain.proceed(request) } }).build() } @Provides @Singleton fun provideGson(): Gson { return GsonBuilder()
