指纹扫描仪触发华为P10的家庭动作

Question

我正在使用FingerprintManager / BiometricPrompt（取决于Android版本）来访问KeyStore。然而，在具有用于“家庭”和扫描仪的单个电容键的电话（如华为P10）中，提到的指纹扫描功能会触发“家庭”操作！

对此有任何解决方法吗？可能是暂时封锁首页？

此代码或多或少：

@RequiresApi(Build.VERSION_CODES.M)
private fun fingerptintDoOnEncrypt(context: Context?, onSuccess: () -> Unit, onDismiss: () -> Unit) {
    try {
        "test".toByteArray().encryptWithAes(bioCipher, bioKey, "test")
        onSuccess()
    } catch (ex: UserNotAuthenticatedException) {
        val mFingerprintManager = context.getSystemService(Context.FINGERPRINT_SERVICE) as FingerprintManager

        val cancellationSignal = CancellationSignal()
        val callback = object : FingerprintManager.AuthenticationCallback() {
            override fun onAuthenticationSucceeded(result: FingerprintManager.AuthenticationResult) {
                currentDialog?.dismiss()

                lastBiometrySuccessful = true
                "test".toByteArray().encryptWithAes(bioCipher, bioKey, "test")
                onSuccess()
            }

            override fun onAuthenticationFailed() {
                Toast.makeText(context, s(R.string.biometry_failed), Toast.LENGTH_SHORT).show()
                super.onAuthenticationFailed()
            }

            override fun onAuthenticationError(errorCode: Int, errString: CharSequence?) {
                currentDialog?.dismiss()

                cancellationSignal.cancel()
                lastBiometrySuccessful = false
                if (errorCode == FingerprintManager.FINGERPRINT_ERROR_CANCELED) {
                    Toast.makeText(context, s(R.string.biometry_failed), Toast.LENGTH_SHORT).show()
                }
            }
        }

        context?.let {
            showAlert(context, cancellationSignal, onDismiss)

            // FingerprintManager.CryptoObject(mCipher)
            mFingerprintManager.authenticate(null, cancellationSignal, 0, callback, null)
        }
    }
}


@RequiresApi(Build.VERSION_CODES.P)
private fun biometryDoOnEncrypt(context: Context?, onSuccess: () -> Unit, onDismiss: () -> Unit) {
    try {
        // TODO - potencjalnie może powodować problemy, jeśli hasło wygaśnie krótko po tym
        "test".toByteArray().encryptWithAes(bioCipher, bioKey, "test")
        onSuccess()
    } catch (ex: UserNotAuthenticatedException) {
        if (context == null)
            return

        val biometricManager = BiometricPrompt.Builder(context)
                .setTitle(context.getString(R.string.biometry_dialog_title))
                .setDescription(context.getString(R.string.biometry_dialog_desc))
                .setNegativeButton(context.getString(android.R.string.cancel), context.mainExecutor, DialogInterface.OnClickListener { dialogInterface, i -> onDismiss() })
                .build()

        val cancellationSignal = CancellationSignal()

        val callback = object : BiometricPrompt.AuthenticationCallback() {
            override fun onAuthenticationSucceeded(result: BiometricPrompt.AuthenticationResult) {
                lastBiometrySuccessful = true
                "test".toByteArray().encryptWithAes(bioCipher, bioKey, "test")
                onSuccess()
            }

            override fun onAuthenticationFailed() {
                lastBiometrySuccessful = false
                Toast.makeText(context, s(R.string.biometry_failed), Toast.LENGTH_SHORT).show()
                super.onAuthenticationFailed()
            }

            override fun onAuthenticationError(errorCode: Int, errString: CharSequence?) {
                // nierozwiązywalny błęd, nie będzie więcej callbacków

                cancellationSignal.cancel()
                lastBiometrySuccessful = false
                if (errorCode == BiometricPrompt.BIOMETRIC_ERROR_CANCELED) {
                    Toast.makeText(context, s(R.string.biometry_failed), Toast.LENGTH_SHORT).show()
                }
            }
        }

        biometricManager.authenticate(cancellationSignal, context.mainExecutor, callback)
    }
}
