问题 I want to use Dagger2. Say I have the following dependencies: Class A depends on class B Class B depends on class C I tried to create a Module that provides B and C, and a Component that provides A, however only B is injected into A, and the reference to C in B remains null. What is the classes structure I need to implement using dagger? 回答1: You can either use constructor injection or field injection; and either constructor-inject or module-inject. Constructor-@Inject might be buggy, because

问题 In order to learn Dagger 2 i decided to rewrite my application but I'm stuck with finding the proper solution for the following problem. For the purpose of this example let's assume we have an interface called Mode : public interface Mode { Object1 obj1(); //some other methods providing objects for app } and two implementations: NormalMode and DemoMode . Mode is stored in singleton so it could be accessed from anywhere within application. public enum ModeManager { INSTANCE,; private Mode mode

问题 This question was created from first part of PowerMock + Robolectric + Dagger2 So i'm a little bit again. Sorry. I test custom view class which contain: android ui elements some logic static methods callings dagger2 dependencies So i use next tools for testing Robolectric for UI elements mocking unit tests for logic testing PowerMock for static methods mocking Robolectric + PowerMock integration problem is known and solution is known - https://github.com/robolectric/robolectric/wiki/Using
