嗨，我受 Google Analytics 和我的 GWT 应用程序链接的困扰好几天了。 在我的应用程序中，我需要从 Google Analytics 接收数据处理（例如访问者数量）。 可能示例和库很旧（我认为）
我的问题，我如何解决接管数据？我附上我的代码，看看我是否刺伤了什么。谢谢你的回答！

System.out.println("Most fogja az acc bejegyzeseit lekerdezni");// debug
service.getAccountFeed(accountsFeedUri, new AccountFeedCallback() {

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());
