特定三星设备上的指纹崩溃

Question

我最近发布了一个新应用程序,其中包含对通过指纹进行身份验证的支持

这在我们所有的测试设备上运行良好:
- OnePlus Three
- OnePlus Five
- 三星S6 Edge
- 三星S7
- 三星S8

但是当发布时,我们开始通过这个堆栈跟踪从Fabric崩溃:

根据Fabric的说法,这些设备正在经历崩溃:
- Galaxy A5
- Galaxy S5 Mini
- Galaxy A3(2016)

所有这些都运行Android 6.0.1.

看到他们都是三星设备,我开始怀疑Knox可能是问题,即使它没有专门列在堆栈跟踪中的任何地方.但我不知道如何解决它,或解决它.

我在三星自己的网站上发现了类似的问题,但没有修复:https:

在堆栈跟踪中命名的权限是系统权限,没有用户应用程序可以获得.只有系统应用才可以.

有没有人知道如何解决这个问题？

不确定您是否能够找到解决方案，作为解决方法，我只是将我们的调用包装在权限检查中。

inline val Activity.fingerprintManager: FingerprintManagerCompat?
  get() = (
    if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.USE_FINGERPRINT) == PackageManager.PERMISSION_GRANTED) {
      FingerprintManagerCompat.from(this)
    } else { null }
  )
