Android how to access fingerprint from external bio-metric device?

Question

For above version SDK 23 using permissions I am able to fetch result from fingerprint using external biometric device.

 //Get an instance of KeyguardManager and FingerprintManager//
keyguardManager =
  (KeyguardManager) getSystemService(KEYGUARD_SERVICE);
fingerprintManager =
  (FingerprintManager) getSystemService(FINGERPRINT_SERVICE);

textView = (TextView) findViewById(R.id.textview);


if (!fingerprintManager.isHardwareDetected()) {
    textView.setText("Your device doesn't support fingerprint authentication");
}
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.USE_FINGERPRINT) != PackageManager.PERMISSION_GRANTED) {
  textView.setText("Please enable the fingerprint permission");
}

if (!fingerprintManager.hasEnrolledFingerprints()) {
  textView.setText("No fingerprint configured. Please register at least one fingerprint in your device's Settings");
}

if (!keyguardManager.isKeyguardSecure()) {
  textView.setText("Please enable lockscreen security in your device's Settings");
} else {
  try {
        generateKey();
      } catch (FingerprintException e) {
        e.printStackTrace();
      }
}

But I am stuck to get fingerprint result from below version of SDK 23.

Please provide some ideas if someone handle fingerprint authentication in below version of SDK 23 by using external bio-metric device.

AFAIK There is no any direct library available to get fingerprint data from external bio-metric device.

If you're using any external bio-metric device, then you have to check for their developer SDK. Every different device has their SDK to access its data . So I'm suggesting you to check their developer section about the SDK.
