问题
I am currently doing research on Android fingerprint API.
As I have cloned the fingerprint sample, 'FingerprintDialog' https://github.com/googlesamples/android-FingerprintDialog
There is a mechanism for checking if new fingerprint is added to the device and ask for password instead of fingerprint once after the addition of new fingerprint.
However, I cannot find any material online about detecting the removal of fingerprint in the App. As the result, I would like to know if there is any method that I can detect the removal of fingerprint in my App.
Thank you all in advance.
