Facebook错误某些设备的无效密钥哈希
问题描述：
该错误仅适用于已安装Facebook应用程序的设备，否则仅适用于未安装Facebook应用程序的设备，它可以正常工作. 而且它显示的哈希密钥不是我保存在facebook的开发人员网站中的密钥.
the error is only for devices which have facebook app installed otherwise for the devices which don't have facebook app installed, it's working properly. And the hash key it is showing is not one which I have saved in developers site of facebook.
在此方面的任何帮助，我将不胜感激. 请参考图片以获取错误的屏幕截图
I would appreciate any help on this. please refer image for screenshot of error
答
将Hash密钥添加到Facebook的开发者控制台.
Add your Hash key to Developer Console of Facebook.
此问题可能是由于密钥存储而发生的.
This issue might be happened because of key store.
