无法初始化AccountKit Android Studio。 初始化错误501

Question

我想使用AccountKit创建一个简单的应用程序，该应用程序在成功登录后显示“ hello world”消息。 “ activity_main.xml”包含一个简单的“ hello world”消息。 语法上没有错误，但是当我尝试在手机上运行时，我收到有关帐户工具包SDK初始化的错误。 我已经在LoginActivity中明确初始化了accountkit sdk，如此处所示 。 没有与AccountKit类关联的名为initializeSdk（）的函数。 请帮我。

创建一个名为DemoApplication或您希望扩展Application的任何新名称的新类。 如下面的代码所示，在您的清单文件中注册此类。 然后在DemoApplication.java文件的onCreate（）中初始化Fb Account工具包

public class DemoApplication extends Application {

  @Override
  public void onCreate() {
       super.onCreate();
       AccountKit.initialize(getApplicationContext());
  } 
}

然后在您的Mainifest的Application元素中注册此类

<?xml version="1.0" encoding="utf-8"?>
