How can I use it in an Activity

[woxingxiao]

Thanks for your excellent work for this lib. 👍👍

But why the BiometricHelper has to be instanced in a fragment? How can I use it in an activity?

class BiometricHelper(private val fragment: Fragment) 

Isn't this a better way?

class BiometricHelper(private val context: Context)

Hello,
Sorry this is not possible due to the implementation of Google of BiometricPrompt.
You absolutely need a Fragment or a FragmentActivity:
