获取谷歌驱动器的帐户信息的问题

我正在开发一个谷歌驱动器上的Android应用程序，我想获取驱动器中使用的用户名和空间，并试图按照https://developers.google.com/drive/v2/reference/about/get这样做，我尝试了下面的代码，获取谷歌驱动器的帐户信息的问题

private static void printAbout(Drive service) { 
try { 
    About about = service.about().get().execute(); 

    System.out.println("Current user name: " + about.getName()); 
    System.out.println("Root folder ID: " + about.getRootFolderId()); 
    System.out.println("Total quota (bytes): " + about.getQuotaBytesTotal()); 
    System.out.println("Used quota (bytes): " + about.getQuotaBytesUsed()); 
} catch (IOException e) { 
    System.out.println("An error occurred: " + e); 
} 
    }

但是，它返回错误，并且日志猫显示

它不会允许你在主线程上这样做，因为它会锁定你的应用程序直到它完成。如果此过程需要超过5秒钟，则Android操作系统将关闭您的应用程序。

您需要使用像AsyncTasks这样的后台线程。
