Crash on Sample App startup, after adding local.properties and google-services.json

The bug is probably in EncryptedSharedPreferences from androidx.security:security-crypto. See more:
https://issuetracker.google.com/issues/164901843?pli=1

However it would be nice if you can think about some workaround for it, because otherwise we risk a crash on startup in our app, after implementing OKTA Push SDK in the way how do you suggest it in the sample.

Hi @pkrawczykObj For testing you can disable encryption by using shared preference.

    private val sharedPreferences: SharedPreferences = app.getSharedPreferences(passphraseSharedPref, Context.MODE_PRIVATE)

Replace encrypted shared preference with shared pref in

okta-devices-kotlin/push-sample-app/src/main/java/example/okta/android/sample/client/AuthenticatorClient.kt

Line 64 in bb9d6a7

private val sharedPreferences: SharedPreferences = EncryptedSharedPreferences.create(

Hi @FeiChen-okta

Ok and what are your recommendations for production version of the app to avoid this issue?

Hi @FeiChen-okta

The android encryption library uses tink and it looks like it has issues https://issuetracker.google.com/issues/158234058

My recommendation is try 1.1.0-alpha06 which was released yesterday. This updated tink to 1.8.0.
If that doesn't fix the issue then writing own encryption is another option.

Your recommendation does not fixed the issue and I switched to my own encryption. Maybe it would be worth to mention about it in Readme or change the sample implementation, because it caused the app crash on startup, which can be really painfull.
