Callback/broadcast 来自 android 设备的 Adding/Removing 指纹

Question

当您adding/removing从设备中提取指纹时，是否有任何回调或广播发送。

如果有多个指纹，有没有办法找到指纹的ID。

非常感谢任何帮助。

Answer 1

不，没有回调。每次都要检查是否录入了一些指纹，如下：

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 
}
