こんにちは、Google アナリティクスと GWT アプリケーションのリンクで何日も苦しんでいます。私のアプリでは、Google アナリティクスから受け取ったデータ (訪問者数など) を処理する必要があります。おそらくサンプルとライブラリが古い (と思います)

私の質問は、どうすればデータを引き継ぐことができますか? 私のコードを添付して、何かを刺したかどうかを確認します。答えてくれてありがとう!

private static void getAccounts(String accountsFeedUri) {
    System.out.println("Most fogja az acc bejegyzeseit lekerdezni");// debug

    service.getAccountFeed(accountsFeedUri, new AccountFeedCallback() {

        @Override
        public void onSuccess(AccountFeed result) {

            System.out
                    .println("Sikerült lekérdezni az account bejegyzéseit");// debug
            AccountEntry[] entries = result.getEntries();
            System.out.println("Megy a lekérdezés");// debug
            AccountEntry targetEntry = entries[0];
            queryData(targetEntry.getTableId().getValue());
            if (entries.length == 0) {
                System.out.println("Nincs ga accod");// debug
            } else {
                System.out.println("Megy a lekérdezés");// debug
                // AccountEntry targetEntry = entries[0];
                queryData(targetEntry.getTableId().getValue());
            }
        }

    });
