【中文标题】无法初始化 AccountKit android 工作室。初始化错误 501【英文标题】：unable to Initialize AccountKit android studio. Initialization Error 501 【发布时间】：2016-06-09 20:14:20 【问题描述】：我想使用 AccountKit 创建一个简单的应用程序，它会在成功登录时显示“hello world”消息。 “activity_main.xml”包含一个简单的“hello world”消息。语法没有错误，但是当我尝试在手机上运行此程序时，我收到有关帐户工具包 sdk 初始化的错误。我已经在给定的here 中清楚地初始化了 LoginActivity 中的 accountkit sdk。没有与 AccountKit 类关联的名为 initializeSdk() 的函数。请帮帮我。

【问题讨论】：
【参考方案1】：创建一个名为 DemoApplication 的新类或任何您喜欢的扩展 Application 的名称。在您的清单文件中注册此类，如下面的代码所示。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 Mainifest 的 Application 元素中注册这个类
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.androidyug.demoaccountkit">
