BiometricHelper- Fingerprint recognition, face recognition, custom pop-ups, super easy to use

Making the address Yards cloud address

Based on android native fingerprint recognition and facial recognition tools, you can customize pop-ups as required

Project presentations

Features and functions:

• Support system pop-ups
• SDK pop-ups are supported
• Supports custom pop-ups

FAQ

• Why does facial recognition popup window not appear when accessing SDK?
  • Many phones don’t have face unlock
  • Face unlock is not enabled
  • Face unlock is available and the recognition popup window may not appear when face unlock is enabled
  • Currently, I know Samsung S21 is capable of facial recognition. If you have more models, you can leave a message if you turn up the popup window of facial recognition
• Why is there no fingerprint recognition when accessing SDK?
  • The fingerprint unlock function is not supported or disabled

Copy the code

Main calling code

private fun showDialog(enableAndroidP: Boolean) {
    BiometricPromptManager.Builder(this)
    // Start android popover default true, set to false Facial recognition does not take effect
            .enableAndroidP(enableAndroidP)
            .setCallback(fingerprintCallback)
            .title("Please verify fingerprints/faces entered.")
            .cancelText("Cancel")
    // enableAndroidP false Only for android 8 or later
            .setImgRes(R.drawable.ic_fingerprint)
            .failTitle("Failed to identify fingerprints.")
            .failContent("Try it again.")
    // Custom pop-ups (using factory mode, inheriting IBiometricDialog)
    //.setCustomDialog(BiometricDialogCustomImpl())
            .build()
}
