dagger

I'm wondering if there is a way for Dagger to know that it should recreate an object when new data is available. The instance I am speaking of is with the request headers I have for retrofit. At some point (when the user logs in) I get a token that I need to add to the headers of retrofit to make authenticated requests. The issue is, I'm left with the same unauthenticated version of retrofit. Here's my injection code: @Provides @Singleton OkHttpClient provideOkHttpClient(Cache cache) { HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor(); interceptor.setLevel

Dagger 2 is around the corner but the available examples wouldn't even compile right off the box, and the documentation is a copy-paste-replace from Dagger 1. Does anyone have an example of a proper application working on Google's Dagger 2? I've just published sample app based on Gradle which integrates Dagger2, retrolambda, butterknife and lombok. You can find it here: https://github.com/mgrzechocinski/dagger2-example . Hope it would help :) I've just ported u2020-mvp app to Dagger 2. We use it as our sandbox app. Dagger 2 has nice implementation of scopes by the way. Components are really

I am using dagger2 library. whenever I am trying to run my project is says not able to create instance of view model class. main activity where I am trying to create an instance ((MovieApplication) getApplication()).getAppComponent().inject(this); mViewModel = ViewModelProviders.of(this).get(MoviesDataViewModel.class); My factory class public class ViewModelFactory implements ViewModelProvider.Factory { private MoviesDataViewModel mViewModel; @Inject public ViewModelFactory(MoviesDataViewModel viewModel) { this.mViewModel = viewModel; } @Override public <T extends ViewModel> T create(Class<T>

I have a library project/module that is used by both Android apps and regular java apps. In Dagger 1 this project/module has property complete = false . Within there is an @Inject field that is not satisfied by any class implementation or @Provides method. The idea is to force the "top" module(s) which has complete = true to provide system specific implementation Just for the sake of example: In the library project I have ActLogin activity that have field @Inject @Named("app version") mAppVersion . The value of this field is used when logging in into a server. ActLogin is used by several apps

I am new to Dagger 2. I have 2 Activities, I want to use injected ViewModel for both. Here is my ViewModuleFactory : @Singleton public class ProductViewModelFactory implements ViewModelProvider.Factory { private final Map<Class<? extends ViewModel>, Provider<ViewModel>> creators; @Inject public ProductViewModelFactory(Map<Class<? extends ViewModel>, Provider<ViewModel>> creators) { this.creators = creators; } @SuppressWarnings("unchecked") @Override public <T extends ViewModel> T create(Class<T> modelClass) { Provider<? extends ViewModel> creator = creators.get(modelClass); if (creator == null

有待修正。。。 对于全同多粒子态，有密度算符 \(\rho_N\) ，现在要对其约化，求出单体的约化密度算符。由于全同粒子中，各个粒子地位相同，所以 \(N\) 粒子的约化单体密度算符为 \[ \rho=N\text{tr}_{2,3,\cdots,N}(\rho_N) \] 其中系数 \(N\) 是因为有 \(N\) 个全同的粒子。求trace就是选取一组完备基矢量，作用在 \(\rho\) 两边，然后对所要约化的粒子积分(求和)。为求trace，取一个多粒子的对称化基矢组 \(|b_1,b_2,\cdots,b_N\rangle\) ，它是完备的，表示 \(N\) 个粒子处于一共这 \(N\) 个态上。于是有 \[ \rho(b,b')=N\int\cdots\int\text{d}b_2\text{d}b_3\cdots\text{d}b_N\langle b,b_2,\cdots,b_N|\rho_N| b',b_2,\cdots,b_N\rangle \] 上面对粒子 \(2,3,\cdots,N\) 积分，而对第一个粒子保留不作积分。由于选取的是对称化基矢量，所以上式左边不能写成 \(\langle b|\rho|b'\rangle\) ，而只能写为 \(\rho(b,b')\) . 这就是单体密度矩阵(因为它一般不写成算符的形式，只写成矩阵元的形式
