Feb 19, 2020 11:16AM

When Biometric prompt is shown in App with setDeviceCredentialAllowed(true), It is not dismissed when device home button is pressed. It throws BiometricPrompt.ERROR_USER_CANCELED error and keeps the System UI as is.

Note : I am using androidx.biometric:biometric:1.0.1

I don't know what's going on with the link - I can't edit, it's supposed to be: https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:biometric/biometric/src/main/java/androidx/biometric/BiometricFragment.java;l=379-383;drc=e09aec149238b29f9f828fdf25280e29e245d2b1

Fix workaround of forcing strong biometrics

Expand for full commit details

Fix workaround of forcing strong biometrics 
 
1. Use mPromptInfo.getAllowedAuthenticators() to decide whether to use 
   fake crypto object to force strong biometric, instead of the 
   consolidated authenticators. 
2. Replace isStrongBiometricAllowed() with isAtLeastStrength().

Still seeing this issue on Android 10 Pixel 4.

[Deleted User] <[Deleted User]> #7Feb 25, 2021 05:32AM

Our team is facing this issue as well. What are the alternatives available right now apart from cloning the library and changing the behavior?

sy...@atlassian.com <sy...@atlassian.com> #8Jul 13, 2021 08:11PM

Biometric prompt is also not dismissed if user goes to different apps on API levels below 29. The same behavior is not true for API 29 and above. Is there any workaround for this?
