Again: Android: 10 Android Build: QP1A.190711.020 Manufacturer: samsung Model: SM-G781W
It seems that this issue happens on Samsung phones running Android 10.
re...@gmail.com <re...@gmail.com> #4
I was able to reproduce the same issue using a Samsung Galaxy S20 running Android 10.
Basically, what I have to do to reproduce this issue was to register only Face Recognition (which is a weak authenticator) in the phone and then try to use the app that I'm implementing.
As soon as I registered a Fingerprint in the device, I was not able to reproduce this issue anymore.
Also, I've noticed that my app was also calling the same method twice because of the logic that I had on my observables.
In summary, the issue with BiometricManager.canAuthenticate(BIOMETRIC_STRONG)
is easier to reproduce if the method is called more than once in a row and on a Samsung phone with only Face Recognition registered.
I don't think that calling the method multiple times is the root cause of this issue, but I think it makes easier to the reproduce the issue. Possibly, the error occurs because the biometrics framework is not ready/busy to process the request and returns a KeyStoreException: 16
.
Description
BUILD INFO
STEPS TO REPRODUCE
I'm not sure, as the issue came from our crash report system. It is just a random crash that happened after calling
BiometricManager.canAuthenticate(BIOMETRIC_STRONG)
. It happened in the Settings screen of our app, which comes after the Login screen, which also calls the same method. In other words, it worked when it was first called, but then it failed later.EXPECTED RESULTS
The call to
BiometricManager.canAuthenticate(BIOMETRIC_STRONG)
should not crashOBSERVED RESULTS
