@ifynn 这个能不能实现取决于安卓的API,目前我还没发现有这种API,支付宝的黑科技,不知道用什么手段是实现的。

@uccmawei 通过指纹id、设备id能否实现?

android API中应该能获取到指纹id、设备id

我之前试过了,能算作是指纹的唯一性的属性的值,都拿不到,你可以再试下看有没有新发现。

@uccmawei 我简单看了下,FingerprintManager 中的 getEnrolledFingerprints() 方法貌似能实现指纹变更检验。需要本地存储当前已经记录的指纹 id,然后利用该方法与本地存储的进行比较,如果有新增就说明指纹变更了。

boolean hasSystemFeature = packageManager.hasSystemFeature(PackageManager.FEATURE_FINGERPRINT);
if (hasSystemFeature) {
//do something
}
