following post Dagger + Retrofit. Adding auth headers at runtime i'm trying to configure the okHttp & adding the jwt auth key to the okHttp by adding interceptor,for this i have created separate interceptor & added it to the Dagger's component so that it can be exposed anywhere.

Now once i hit the login i get the token,setting it using the setJwtToken() method of JwtAuthenticationInterceptor class & when i'm trying with the next endpoints i'm getting 401 error since jwtToken is coming null even though i have setted it.

Below i'm attaching my interceptor,component & module code snaps.

Module

@Provides
 @Singleton
 OkHttpClient provideOkhttpClient(Cache cache) 
 OkHttpClient.Builder client = new OkHttpClient.Builder();
 client.addInterceptor(provideHeaderInterceptor());
 client.cache(cache);
 return client.build();
 


 @Provides
 @Singleton
 Retrofit provideRetrofit(OkHttpClient okHttpClient) 
 return new Retrofit.Builder()
 .addConverterFactory(GsonConverterFactory.create())
 .baseUrl(mBaseUrl)
 .client(okHttpClient)
 .build();
 

 @Provides
 @Singleton
 JwtAuthenticationInterceptor provideHeaderInterceptor()
 return new JwtAuthenticationInterceptor();
 

Component

@Component(modules = AppModule.class, ApiModule.class, StorageModule.class)
@Singleton
public interface NetComponent 
 Retrofit retrofit();
 OkHttpClient okHttpClient();
 SharedPreferences sharedPreferences();
 Gson gson();
 Cache cache();
 KRITILog log();
 JwtAuthenticationInterceptor headerInterceptor();

JwtAuthenticationInterceptor.java

@Singleton
public class JwtAuthenticationInterceptor implements Interceptor 
 private String jwtToken;

 @Inject
 public JwtAuthenticationInterceptor() 

 public void setJwtToken(String jwtToken) 
 this.jwtToken = jwtToken;
 

 @Override
 public Response intercept(Chain chain) throws IOException 
 Request original = chain.request();

 Request.Builder builder = original.newBuilder()
 .header("Authorization","Bearer " +jwtToken);
 //String.format("Bearer %s", jwtToken));

 Request request = builder.build();
 return chain.proceed(request);
 

problem is this line

client.addInterceptor(provideHeaderInterceptor());

there you are creating a new instance of the JwtAuthenticationInterceptor, different from the one provided by dagger. JwtAuthenticationInterceptor should be a dependency of that method. Eg

@Provides
@Singleton
OkHttpClient provideOkhttpClient(Cache cache, JwtAuthenticationInterceptor interceptor) 
 OkHttpClient.Builder client = new OkHttpClient.Builder();
 client.addInterceptor(interceptor);
 client.cache(cache);
 return client.build();
