The following link was very useful: https://medium.com/swlh/okhttp-interceptors-with-retrofit-2dcc322cc3f3

OkHttpClient.Builder httpBuilder = new OkHttpClient.Builder();

//Gson Builder
GsonBuilder gsonBuilder = new GsonBuilder();
Gson gson = gsonBuilder.create();
Timber.plant(new Timber.DebugTree());

// HttpLoggingInterceptor
HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor(message -> Timber.i(message));
httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);


/**
 * injection of interceptors to handle encryption and decryption
 */

//Encryption Interceptor
EncryptionInterceptor encryptionInterceptor = new EncryptionInterceptor(new EncryptionImpl());
//Decryption Interceptor
DecryptionInterceptor decryptionInterceptor = new DecryptionInterceptor(new DecryptionImpl());


// OkHttpClient. Be conscious with the order
OkHttpClient okHttpClient = new OkHttpClient()
    .newBuilder()
    //httpLogging interceptor for logging network requests
    .addInterceptor(httpLoggingInterceptor)
    //Encryption interceptor for encryption of request data
    .addInterceptor(encryptionInterceptor)
    // interceptor for decryption of request data
    .addInterceptor(decryptionInterceptor)
    .build();

//Retrofit
Retrofit retrofit = new Retrofit.Builder()
    .client(okHttpClient)
    .baseUrl(BASE_URL)
    // for serialization
    .addConverterFactory(GsonConverterFactory.create(gson))
    .build();

//ApiService
apiService = retrofit.create(ApiService.class);
