Google authorization

[Jakethefish]

Здравствуйте.
Хочу написать простенькую программку что бы делать операции чтения-записи с Task.

Нашел простенький пример:

package com.main;
import com.google.api.client.auth.oauth2.draft10.AccessTokenResponse;
import com.google.api.client.googleapis.auth.clientlogin.ClientLogin;
import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAccessProtectedResource;
import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAccessTokenRequest.GoogleAuthorizationCodeGrant;
import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAuthorizationRequestUrl;

import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.jackson.JacksonFactory;

import com.google.api.services.tasks.v1.Tasks;
import com.google.api.services.tasks.v1.model.Task;
import com.google.api.services.tasks.v1.model.TaskList;
import com.google.api.services.tasks.v1.model.TaskLists;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;


public class Run {
	static Tasks service;
	
	  public static void setUp() throws IOException {
		    HttpTransport httpTransport = new NetHttpTransport();
		    JacksonFactory jsonFactory = new JacksonFactory();

		    // The clientId and clientSecret are copied from the API Access tab on
		    // the Google APIs Console
		    String clientId = "";
		    String clientSecret = "";

		    // Or your redirect URL for web based applications.
		    String redirectUrl = "";
		    String scope = "https://www.googleapis.com/auth/tasks";

		    // Step 1: Authorize -->
		    String authorizationUrl = new GoogleAuthorizationRequestUrl(clientId, redirectUrl, scope)
		        .build();

		    // Point or redirect your user to the authorizationUrl.
		    System.out.println("Go to the following link in your browser:");
		    System.out.println(authorizationUrl);

		    // Read the authorization code from the standard input stream.
		    BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
		    System.out.println("What is the authorization code?");
		    String code = in.readLine();
		    // End of Step 1 <--

		    // Step 2: Exchange -->
		    AccessTokenResponse response = new GoogleAuthorizationCodeGrant(httpTransport, jsonFactory,
		        clientId, clientSecret, code, redirectUrl).execute();
		    // End of Step 2 <--

		    GoogleAccessProtectedResource accessProtectedResource = new GoogleAccessProtectedResource(
		        response.accessToken, httpTransport, jsonFactory, clientId, clientSecret,
		        response.refreshToken);
		    service = new Tasks(httpTransport, accessProtectedResource, jsonFactory);
		    service.setApplicationName("EasyTaskListTracker");
		  }	  
	  public static void main(String args[]){
		  try {
			setUp();
		} catch (IOException e) {
			e.printStackTrace();
		}
		com.google.api.services.tasks.v1.model.Tasks tasks = null;
		try {
			tasks = service.tasks.list("@default").execute();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		for (Task task : tasks.items) {
		  System.out.println(task.title);
		} 
	  }
}

Как-то можно сделать так чтобы не приходилось каждый раз заходить в гугл и давать своё согласие на доступ к таскам?
То есть избежать этого

		    // Point or redirect your user to the authorizationUrl.
		    System.out.println("Go to the following link in your browser:");
		    System.out.println(authorizationUrl);

		    // Read the authorization code from the standard input stream.
		    BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
		    System.out.println("What is the authorization code?");
		    String code = in.readLine();
		    // End of Step 1 <--
