Dagger 2.11 Injecting in OkHttp Authenticator

Question

I have been using the dagger 2.11 AndroidInjection with no problems until i tried to Inject my Retrofit service in an OkHttp Authenticator in order to handle session timeouts.

AndroidInjection allows only for injections in Activities,Fragments,Services,ContentProviders and BroadcastReceicers.

My questions is how can i use the new Dagger AndroidInjection in a class that is not in the above list?

Answer 1

Just use inject to provide Retrofit, in the same module you provide also okhttp that is used by retrofit

@Singleton
@Provides
OkHttpClient providesOkHttpClient(){
    return new OkHttpClient.Builder()
            .connectTimeout(RETROFIT_API_CONNECTION_TIMEOUT_SECONDS, TimeUnit.SECONDS)
            .readTimeout(RETROFIT_API_CONNECTION_TIMEOUT_SECONDS, TimeUnit.SECONDS)
            .writeTimeout(RETROFIT_API_CONNECTION_TIMEOUT_SECONDS, TimeUnit.SECONDS)
            .build();
}

@Singleton
@Provides
Retrofit providesRetrofit(OkHttpClient client){
    return new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .client(client)
                    .build();
}

Then in your class:

public class MyClass {
   Retrofit mRetrofit;

   @Inject 
   public MyClass(Retrofit retrofit){
      mRetrofit = retrofit;
   }
}
