Android指纹扫描仪，检测用于身份验证的手指
[英]Android Fingerprint Scanner, detecting the finger used for authentication
问题描述
I'm looking to detect which finger is used for device authentication in Android Marshmallow. 
我正在寻找检测哪根手指用于Android棉花糖中的设备身份验证。 The callback used for getting the successful authentication is - 用于获得成功身份验证的回调是-
onAuthenticationSucceeded(FingerprintManager.AuthenticationResult result)
However I don't see how can I use the FingerprintManager.AuthenticationResult object to detect the finger used for authentication. 但是，我看不到如何使用FingerprintManager.AuthenticationResult对象来检测用于身份验证的手指。
Any help is appreciated on this. 任何帮助表示赞赏。

There is absolutely no way to do this, or to hack your way around it. 绝对没有办法做到这一点，或者破解它。 Sorry. 抱歉。
The underlying Fingerprint API is so secure and locked down, and it kind of has to be, as it's data that can be used to open the device and authenticate the user. 底层的指纹API是如此安全且被锁定，它必须具有一定的安全性，因为它的数据可用于打开设备并验证用户身份。

No, i think theres no such facility provided by android till now. 不，我认为到目前为止，Android还没有提供这种功能。 so, there is no way to found detecting the finger used for authentication. 因此，无法找到检测用于认证的手指的方法。
