当 IRIS 扫描仪无法验证用户身份时,没有收到任何回调

问题描述

当 IRIS 扫描器无法对用户进行身份验证时,不调用 Android Biometric API 上的任何回调( onAuthenticationError 或 onAuthenticationFailed )。

安卓版本:10, 三星 S9,一个 UI 2.1

SDK:androidx.biometric:biometric:1.2.0-alpha01 (https://github.com/android/security-samples/issues/73)

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    
    Executor executor = ContextCompat.getMainExecutor(this);
    BiometricPrompt biometricPrompt = new BiometricPrompt(MainActivity.this,executor,new BiometricPrompt.AuthenticationCallback() {
        @Override
        public void onAuthenticationError(int errorCode,@NonNull CharSequence errString) {
            super.onAuthenticationError(errorCode,errString);

            Toast.makeText(getApplicationContext(),"Authentication error: " + errString + errorCode,Toast.LENGTH_SHORT)
                    .show();
        }

        @Override
        public void onAuthenticationSucceeded(
                @NonNull BiometricPrompt.AuthenticationResult result) {
            super.onAuthenticationSucceeded(result);
            Toast.makeText(getApplicationContext(),"Authentication succeeded!",Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onAuthenticationFailed() {
            super.onAuthenticationFailed();
            Toast.makeText(getApplicationContext(),"Authentication failed",Toast.LENGTH_SHORT)
                    .show();
        }
    });

    BiometricPrompt.PromptInfo promptInfo = new BiometricPrompt.PromptInfo.Builder()
            .setTitle("Biometric login for my app")
            .setSubtitle("Log in using your biometric credential")
            .setNegativeButtonText("Use account password")
            .setConfirmationRequired(true)
            .setAllowedAuthenticators(BiometricManager.Authenticators.BIOMETRIC_STRONG)
            .build();

    BiometricManager biometricManager = BiometricManager.from(this);
}
