Answer 1

经过长时间的斗争，我找到了自己的解决方案来解决上述问题。 Facebook最近发布了他们的新SDK，以提高安全性。 在您的应用中使用facebook SDK有一些要求。

1. 该应用程序应该发送提交，并需要Facebook批准才能在Facebook内使用，以使您自己的应用程序显示朋友的详细信息，访问位置和其他特殊权限批准手续类似于谷歌app store的批准手续。

2. 该应用程序必须列在Google Play中，或者您可以将其作为测试用户进行集成（例如，在Google Play中进行beta测试）。

3. 应用程序应具有正确的程序包名称，启动活动，域名，网站URL和电子邮件。

4. 注册的应用程序ID必须与必须为在不同计算机上开发的用户生成的应用程序名称和哈希密钥匹配

5. 需要添加基本的应用程序信息，包括屏幕截图 ， 描述和应用程序徽标

6. 成功批准后，将在您的应用名称附近显示“有效”符号。

我希望这对别人有用 !!!

花了很多时间试图解决这个问题后，我想为仍在寻找的人添加以下内容：

1. 您将在列表中看到的具有user_friend权限的唯一朋友是已登录并批准您的应用的其他用户。 即如果没有其他人使用它，你将不会在列表中（我知道，如果你全部阅读，这是显而易见的）
2. 最简单的测试方法是设置测试应用程序，在“角色”下的facebook界面中添加测试用户，确保测试用户是朋友，然后在应用程序上每次使用时登录。 只有这样他们才会出现在列表中。

3. 除非你特别要求，否则你的应用程序将不具有user_friends权限（但是，你不需要通过Facebook查看它，因为它是基本权限的一部分） – 我将它添加到Splash Segment中的onCreateView（来自SDK中的Scrumptios / Login示例如下：

    LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button); loginButton.setReadPermissions(Arrays.asList("user_friends")); 

4. 使用Facebook测试用户界面作为测试用户登录Facebook，以validation他们是否已接受正确的权限（在应用程序下）。
