Scribe OAuth Java Google Calendar api. NO Client libraries

Question

I've some code for interacting with dropox. Here it is:

public class DropBoxRestClient {
    // Access codes #1: per application used to get access codes #2 
    private static final String API_APP_KEY = "NOT_OF_YOUR_CONCERN";

    public static void main(String[] args) {

        Scanner in = new Scanner(System.in);

        OAuthService service = new ServiceBuilder()
                                .provider(DropBoxApi.class)
                                .apiKey(API_APP_KEY)
                                .apiSecret(API_APP_SECRET)
                                .build();

        Response response = request.send();

        System.out.println("Got it! Lets see what we found...");

        System.out.println("END RESPONSE ===============");

        JSONObject rj = (JSONObject) JSONValue.parse(response.getBody());
        JSONArray contents = (JSONArray) rj.get("contents");
        for (int i=0; i<contents.size(); i++) {

        }
    }

        request.addHeader("Content-Type", "text/plain");
        request.addPayload("I love Cocain!");
        service.signRequest(accessToken, request);
        Response response = request.send();

        System.out.println("Is File Created? Lets see what we found...");
        System.out.println("HTTP RESPONSE: =============");

        Gson gson = new GsonBuilder().setPrettyPrinting().create();
        String jsonItem = gson.toJson(jsonAllObj);

        System.out.println(jsonItem);
    }

    private static void deleteFile(String path, OAuthService service, Token accessToken) throws ParseException {

        Gson gson = new GsonBuilder().setPrettyPrinting().create();
        String jsonItem = gson.toJson(jsonAllObj);

        System.out.println(jsonItem);
    }
}

(This code works perfectly BTW)
What I am in pain to know is whether I can do a similar thing with google APIs using scribe. The thing is I can't find NO APP_KEY or APP_ID. I've created a project in Google Developers Console with credentials OAUTH as Web App and there are no such APP keys or IDs.

You are almost there, from https://developers.google.com/console/help/new/#generatingoauth2

Go to the Google Developers Console.
Select a project, or create a new one.
In the sidebar on the left, expand APIs & auth. Next, click APIs. In the list of APIs, make sure all of the APIs you are using show a status of ON.
In the sidebar on the left, select Credentials.
Click Create new Client ID.
Select the appropriate Application Type for your project and enter any additional information required.

I want to make an app, which will be run in a web server (tomcat) and people connect to the web server. So, I've created a native application as a Google Chrome app. But there is no app_key or app_secret in it :( – jomicobasi Dec 03 '14 at 23:08
If you are trying to make a Google Chrome app, then i think thats not possible to use the same scenario, check: https://developers.google.com/accounts/cookbook/platforms/Chrome – Leandro Carracedo Dec 03 '14 at 23:41
You could obtain a client id and client secret if you generate them for a web app. – Leandro Carracedo Dec 03 '14 at 23:44
yes but are [CLIENT id and secret] == [APP id and secret]? If yes, then I've been going around the roundabout X( – jomicobasi Dec 04 '14 at 00:10

The answer is yes! :) – Leandro Carracedo Dec 04 '14 at 00:23
