我非常有兴趣学习如何开发使用指纹认证的Android应用程序。

我如何实现指纹认证？

Answer 1

<强> Fingerprint Authentication是你想要的:

This release offers new APIs to let you authenticate users by using their fingerprint scans on supported devices, Use these APIs in conjunction with the Android Keystore system.

To authenticate users via fingerprint scan, get an instance of the new FingerprintManager class and call the authenticate() method. Your app must be running on a compatible device with a fingerprint sensor. You must implement the user interface for the fingerprint authentication flow on your app, and use the standard Android fingerprint icon in your UI. The Android fingerprint icon (c_fp_40px.png) is included in the Fingerprint Dialog sample. If you are developing multiple apps that use fingerprint authentication, note that each app must authenticate the user’s fingerprint independently.

To use this feature in your app, first add the USE_FINGERPRINT permission in your manifest.

<uses-permission
        android:name="android.permission.USE_FINGERPRINT" />
