How do I connect Android apps with Google Sheets spreadsheets?

Question

I\'m trying to do an Android app that needs to work with Google spreadsheet API. I\'m new in this, so I\'m starting with the version 3 of the api: https://developers.google.

Thank you so so much Scorpion! It works!! I've been trying this for too long. Ok here is my solution: I started a new project and included these jars:

gdata-client-1.0
gdata-client-meta-1.0
gdata-core-1.0
gdata-spreadsheet-3.0
gdata-spreadsheet-meta-3.0
guava-13.0.1  

and my code:

    SpreadsheetService spreadsheet= new SpreadsheetService("v1");
    spreadsheet.setProtocolVersion(SpreadsheetService.Versions.V3);

    try {
        spreadsheet.setUserCredentials("username", "password");
        URL metafeedUrl = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");
        SpreadsheetFeed feed = spreadsheet.getFeed(metafeedUrl, SpreadsheetFeed.class);

        List spreadsheets = feed.getEntries();
        for (SpreadsheetEntry service : spreadsheets) {             
            System.out.println(service.getTitle().getPlainText());
       }
    } catch (AuthenticationException e) {           
        e.printStackTrace();
    }

of course this is executed in a different thread not in the main thread. There is no java documentation for OAuth 2.0 but I will try and if I can't do it I'll ask here. Again, thank you very much and I hope to help you when I work on this time enough. :)
