I want to add a finger print scanner in my android app for authentication. I have searched on google but found finger print support only for android marshmallow. I want to add this for android API version 14 to 23. How can I achieve this ?

  • Finger Print Sensor introduced in Android 6.0, Here is the google doc https://developer.android.com/about/versions/marshmallow/android-6.0.html. Also Finger print Sensor hardware came recently in Android phone so I don't think supporting API version 14 to 23 is useful. – Rajendra Aug 31 '16 at 07:38

You cannot. Fingerprint API was added in Marshmallow (API 23). You can still target API 14 with FingerprintManagerCompat. Pre Marshmallow it behaves as there would be no fingerprint hardware available.
