Steps to reproduce the Behavior

It's random. Personally I wasn't able to reproduce it but I received a few crash reports. Looking at the stacktrace I believe it may relate to xamarin/Essentials#380

Expected Behavior

App doesn't crash.

Actual Behavior

App crashes:

Code snippet

Preferences.get_IsLoginInfoSaved has the following code:

_settingsInstance.GetValueOrDefault(KeyUsername, null)

_settingsInstance is an ISettings instance.

I just magically started getting this error recently. i have two apps listening to the same firebase reference. when i call the setvalue() method i get this exception.

Having this issue too. Mine happens when I try to access Xamarin.Essentials.Preferences through "ViewAppeared" lifecycle method in MvvmCross Viewmodel.

Specifically when coming back from another activity.

Im getting this issue randomly as well on
var UserType = Plugin.SecureStorage.CrossSecureStorage.Current.GetValue("UserType");

with crosssecurestorage

we are using Xamarin.Android
were you able to solve this issue?

[guillermo-gerard]

I found this issue and even though I'm not using Essentials, I want to share how I stopped this from occurring:
I was using just sharedPreferences as I'm working on a xamarin android app, and I was trying to write a value from inside a catch block.
I just took off that from the catch block and I stopped receiving this exception.
I hope this may be useful for someone else...
