dagger

I use Dagger2 for DI in my android application. I found that I have to write inject method for every class that uses @Inject field. Is there a way that I can just inject the parent class so that I don't have to call inject on every subclass? Take Activity for example. I have a BaseActivity that that every Activity extends from. Is there a way that I can just create an inject method in the component for BaseActivity and just call inject in BaseActivity's onCreate, and @inject fields in sub activities get injected automatically? Kirill Boyarshinov It cannot be done right now. Explanation by

Can anyone point out the difference between Dagger and Butterknife ? I know that Butterknife is a view injection library and Dagger is a dependency injection library. But the documentation online seems a bit overhead for me. According to Butterknife documentation, you can do non-activity injections as well, which is what Dagger does? Or did I misunderstand something? ButterKnife is targeted to inject views only. Non-activity injection just means that you can provide your own view root to inject views from (like with manually inflated views, etc.). Dagger is a bit more complicated. It can

PROBLEM I need to call API from domains entered by USER and I need to edit my Retrofit singleton before the call accordingly to the inserted data. Is there a way to "reset" my singleton, forcing it to recreate? or Is there a way to update my baseUrl with my data (maybe in Interceptor?) just before call? CODE Singletons @Provides @Singleton Retrofit provideRetrofit(SharedPreferences prefs) { String apiUrl = "https://%1s%2s"; apiUrl = String.format(apiUrl, prefs.getString(ACCOUNT_SUBDOMAIN, null), prefs.getString(ACCOUNT_DOMAIN, null)); OkHttpClient httpClient = new OkHttpClient.Builder()

From dagger-discuss@ : I have a class that gets some dependencies from the object graph, and other dependencies from a caller at runtime. public class ImageDownloader { // Get these dependencies from the injector. private final HttpClient httpClient; private final ExecutorService executorService; // Get these from the caller. private final URL imageUrl; private final ImageCallback callback; ... } I came up with a solution, where I define a Factory, public class ImageDownloader { ... public static class Factory { private final HttpClient httpClient; private final ExecutorService executorService

I'm trying to run Dagger 2 as well as Lombok on my Java project. Lombok has to run first, of course, but whether it actually does seems to be up to chance. At first I suspected I could specify the order by the respective position of the library jars in the class path, but that order evidently gets ignored. Is there a way to specify the order for them to run somehow, or do I simply have to live with not being able to combine two APs ? I have produced an SSCCE test case . A simple git clone & mvn compile is enough to demonstrate the issue - if you comment line 18 and uncomment lines 20-21 in App

EDIT 2018-02-08: Sample project demonstrating how to do this at https://github.com/ravn/dagger2-named-string-inject-example - Note: the whole source is in a single file ! I am looking at whether dagger can replace guice for us (as our deployment Java platform is slow). I construct a map of configuration strings at runtime, which I would like to have dagger inject as needed. E.g. If I have java.util.Map<String, String> map = new java.util.TreeMap<String, String>(); map.put("key", "value"); and @Inject Thermosiphon(Heater heater, @Named("key") String value) { this.heater = heater; System.out
