Handling Retrofit multiple dependent providers

I’not used to work with DI, but from theory point of view I decided to go to Toothpick for clarity and simplicity. However I got some issue resolving injection of Retrofit in my app.

I create a module “NetworkModule”

public class NetworkModule extends Module {
    public NetworkModule(String urlPath) {
        bind(Gson.class).toProvider(GsonProvider.class);
        bind(Retrofit.class).toProviderInstance(new RetrofitProvider(urlPath, new GsonProvider().get()));
}

As you see some providers depends from others. RetrofitProvider need previously injected Gson dependency. How to deal with that ?

Try adding a inject annotation to the constructor of the provider. Toothpick needs the inject annotation on the constructor to create factories.

Something like this:

class GsonProvider 
@Inject
constructor(): Provider<Gson> {
...
}

@kelsos ok thank for the fix.
