created issue #1

Nov 27, 2020 11:00AM

We've had reports from users that BiometricPrompt occasionally doesn't show up when they expect it to, and I found a simple repro when investigating something entirely unrelated - I've attached a sample project.

I haven't investigated the root cause, but when I attach a debugger and stick a breakpoint on this line I can see that BiometricViewModel gets stuck in a state where it thinks it's showing but in fact isn't.

BUILD INFO

Device type: Pixel 4 (emulator)
OS version: 30
Biometric library version: 1.1.0-rc01

STEPS TO REPRODUCE

Install the attached repro app (./gradlew app:iD).
Repeatedly press the 'SHOW PROMPT' button - keep clicking when the biometric prompt dialog shows, so it is immediately dismissed.

EXPECTED RESULTS: When you call authenticate the prompt should always either be shown to the user or call one of the error/failure callbacks.

OBSERVED RESULTS: The prompt gets stuck in a state where it will not show again, and does not call any of the callbacks.

NUMBER OF TIMES YOU WERE ABLE TO REPRODUCE: 10/10
