问题
I am trying to implement FingerPrint Scanner in my app.
I followed below tutorial: http://www.techotopia.com/index.php/An_Android_Fingerprint_Authentication_Tutorial
In Samsung Note 4, FingerPrintManager's isHardwareDetected() is returned as false even though I successfully registered two fingerprints from Settings.
Does anyone of you know what might be the reason? Thanks.
回答1:
I'm afraid the Note 4 doesn't support the Fingerprint API (just the Samsung Fingerprint). You should try your code with another device if possible.
回答2:
The issue is with the implementation of the Fingerprint scanner in some old Samsung phones such as the S5 and the Note 4.
Check this link Android M FingerprintManager.isHardwareDetected() returns false on a Samsung Galaxy S5 to see an example of how you can achieve this using the Samsung pass sdk.
You can also refer to http://img-developer.samsung.com/onlinedocs/sms/pass/index.html for the documentation of the pass sdk.
