Android Github repo api使用Dagger应用程序构建调用应用程序，但是我试图通过运行assembleAndroidTest来生成DaggerTestApplicationComponent，并且它在我下面的stacktrace中中断了
我试图将大多数主要类镜像为测试类，但是它使我无法阅读堆栈跟踪，尤其是当它在某个地方构建时，我接受了我错了
请帮助，欢迎咨询。
ApplicationComponent -------------------------------
@Singleton
@Component(modules = {
ApplicationModule.class,
ActivityBindingModule.class,
ServiceModule.class,
RepoServiceModule.class,
})
public interface ApplicationComponent {
void inject(MyApplication myApplication);
}
ApplicationModule ------------------------------
@Module
public class ApplicationModule {
private final Application application;
ApplicationModule(Application application) {
this.application = application;
}
@Provides
Context provideApplicationContext() {
return application;
}
}
ActivityBindingModule -----------------------------
@Module(subcomponents = {
MainActivityComponent.class
})
public abstract class ActivityBindingModule {
@Binds
@IntoMap
@ActivityKey(MainActivity.class)
abstract AndroidInjector.Factory<? extends Activity> provideMainActivityInjector (MainActivityComponent.Builder builder);
}
ServiceModule -------------------------------------
@Module(includes = NetworkModule.class)
public abstract class ServiceModule {
@Provides
@Singleton
static Moshi provideMoshi() {
return new Moshi.Builder()
.add(AdapterFactory.create())
.add(new ZoneDateTimeAdapter())
.build();
}
@Provides
@Singleton
static Retrofit provideRetrofit(Moshi moshi, Call.Factory callFactory, @Named("base_url") String baseUrl) {
return new Retrofit.Builder()
.callFactory(callFactory)
.addConverterFactory(MoshiConverterFactory.create(moshi))
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.baseUrl(baseUrl)
.build();
}
}
RepoServiceModule -----------------------------
@Module
public abstract class RepoServiceModule {
@Provides
@Singleton
static RepoService provideRepoService(Retrofit retrofit) {
return retrofit.create(RepoService.class);
}
}
我已经创建了一些反映这些测试类的测试类（这是我认为的问题所在。）。
TestApplicationComponent -------------------------
@Singleton
@Component(modules = {
ApplicationModule.class,
TestActivityBindingModule.class,
TestRepoServiceModule.class,
ServiceModule.class,
})
public interface TestApplicationComponent extends ApplicationComponent {
}
TestActivityBindingModule -------------------------
@Module(subcomponents = {
TestMainActivityComponent.class,
})
public abstract class TestActivityBindingModule {
@Binds
@IntoMap
@ActivityKey(MainActivity.class)
abstract AndroidInjector.Factory<? extends Activity> bindMainActivityInjector(TestMainActivityComponent.Builder builder);
}
TestRepoServiceModule ---------------------------
@Module
public abstract class TestRepoServiceModule {
@Binds
abstract RepoService bindRepoService(TestRepoService repoService);
}
可以提供任何其他需要的类。

谢谢
最佳答案
该错误基本上表明您正在尝试注入
ScreenNavigator进入BaseActivity，但是Dagger不知道如何获取实例，因为它缺少提供方法，或者您错过了ScreenNavigator构造函数的@Inject批注
