问题 I am using BiometricPrompt in my application. It works well and shows the dialog when call the authenticate() method. But this dialog gets closing when I click outside the dialog. How to prevent it? How to make BiometricPrompt's dialog non-cancelable? Here is no method like biometricPrompt.setCancelable(false) . 回答1: You have to use the version 1.0.0-beta01 or later. Now it is the default behavior: Touches outside no longer cancel authentication. Back button cancel authentication still. You

问题 I need to integrate Biometric authentication using Fingerprint and Face authentication. Fingerprint authentication works perfectly but when I set only Face authentication I am getting Biometric not enrolled response from BiometricManager.from(context) method as follows, val biometricManager = BiometricManager.from(context) when(biometricManager.canAuthenticate()){ BiometricManager.BIOMETRIC_SUCCESS ->{ Log.e(TAG, "App can authenticate using biometrics.") } BiometricManager.BIOMETRIC_ERROR_NO

问题 we are currently trying to sign data with biometrics, which we use the androidx.biometric library for. The Problem is, if no Fingerprint ist installed but a face registered we cannot generate any keys. With Fingerprint only or with the combination of fingerprint and face everything works perfect. With only the face registered we get the following exception during key generation: Caused by: java.security.InvalidAlgorithmParameterException: java.lang.IllegalStateException: At least one
