title: I don't get spreadsheets from Google docs
body: <p>I took example from <a href="https://stackoverflow.com/questions/30483601/create-spreadsheet-using-google-spreadsheet-api-in-google-drive-in-java">here</a>. But my code below gives me "No spreadsheets found", though I have several spreadsheets at this url <a href="https://spreadsheets.google.com/feeds/spreadsheets/private/full" rel="nofollow noreferrer">https://spreadsheets.google.com/feeds/spreadsheets/private/full</a>.
  I don't understand why I don't get any spreadsheets.</p>
  
  <pre><code>String CLIENT_ID = "132465@developer.gserviceaccount.com";
  URL SPREADSHEET_FEED_URL = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");
      File p12 = new File("key.p12");
      String[] SCOPESArray = {"https://spreadsheets.google.com/feeds", "https://docs.google.com/feeds"};
      final List SCOPES = Arrays.asList(SCOPESArray);
      GoogleCredential credential = new GoogleCredential.Builder()
              .setTransport(new NetHttpTransport())
              .setJsonFactory(new JacksonFactory())
              .setServiceAccountId(CLIENT_ID)
              .setServiceAccountScopes(SCOPES)
              .setServiceAccountPrivateKeyFromP12File(p12)
              .build();
  
      SpreadsheetService service = new SpreadsheetService("GoogleSheet");
  
      service.setOAuth2Credentials(credential);
      SpreadsheetFeed feed = service.getFeed(SPREADSHEET_FEED_URL, SpreadsheetFeed.class);
      List&lt;SpreadsheetEntry&gt; spreadsheets = feed.getEntries();
  
      if (spreadsheets.size() == 0) {
          System.out.println("No spreadsheets found.");
      }     else {
          SpreadsheetEntry spreadsheetEntry = spreadsheets.get(0);
          System.out.println(spreadsheetEntry.getTitle().getPlainText());
      }
  </code></pre>
