android basic auth okhttpclient

I am connecting to my rest api using retrofit and okHttp client. When I disable Basic authentication on Tomcat everything works flawlessly. When Basic Auth is enabled on Tomcat I get 404 Page not found. Here is my authentication and error output.

    okHttpClient.setAuthenticator(new Authenticator() {
        @Override
        public Request authenticate(Proxy proxy, Response response) throws IOException {
            String credential = Credentials.basic(rest_user, rest_pw);
            return response.request().newBuilder().header("Authorization", credential).build();
        }

        @Override
        public Request authenticateProxy(Proxy proxy, Response response) throws IOException {
            return null;
        }
    });

Solution

  • Problem solved using RequestInterceptor. 

      restAdapter = new RestAdapter.Builder()
            .setConverter(new GsonConverter(gson))
            .setRequestInterceptor(new RequestInterceptor() {
                @Override
                public void intercept(RequestFacade request) {
                    String credentials = DownloadService.rest_user + ":" + DownloadService.rest_pw;
                    String base64EncodedCredentials = Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);
                    request.addHeader("Authorization", "Basic " + base64EncodedCredentials);
                }
            })
            .setEndpoint(DownloadService.URL)
            .setClient(new OkClient(okHttpClient))
            .build();
