Hi,

I think it's my mistake, I guess I should not invoke BiometricPrompt from onResume it will cause an infinite loop.

Running on Samsung A50 Android 9 or Emulator Nexus 5X API 27

Android Studio 3.5.1
compileSdkVersion 29
minSdkVersion 21
targetSdkVersion 29

def biometric_version = "1.0.0-rc01"
implementation "androidx.biometric:biometric:$biometric_version"

Scenario 1:
- No biometric or device credentials (PIN, pattern, password) configured
- Biometric prompt not showing
- Tap on Toast button
- Activity is not responding (can't tap on button)

Scenario 2:
- Device credential configured (Pattern)
- Biometric prompt showing pattern authentication
- Tap on Cancel
- Tap on Toast button
- Activity is not responding (can't tap on button)

Expected output : Toast showing when button tapped

But I do not have issue if I remove "setDeviceCredentialAllowed", that's what make me thing there is something wrong

Steps to reproduce:
- Fingerprint configured in settings
- Biometric prompt showing
- Tap on cancel
- Tap on Toast button
- Toast is showing

Scenario 2:
- Device credential configured (Pattern)
- Biometric prompt showing pattern authentication
- Tap on Cancel
- Tap on Toast button
- Activity is not responding (can't tap on button)

Behaviour is not the same between biometric and credentials authentication

Assigning back to triage queue so it's not lost in mine, will take a look soon.
