代码示例1
// Check if we're running on Android 6.0 (M) or higher
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    //Fingerprint API only available on from Android 6.0 (M)
    FingerprintManager fingerprintManager = (FingerprintManager) context.getSystemService(Context.FINGERPRINT_SERVICE);
    if (!fingerprintManager.isHardwareDetected()) { 
        // Device doesn't support fingerprint authentication     
    } else if (!fingerprintManager.hasEnrolledFingerprints()) { 
        // User hasn't enrolled any fingerprints to authenticate with 
    } else { 
        // Everything is ready for fingerprint authentication 
    }
}
