"Attempt to invoke interface method 'int android.security.IKeystoreService.exist(java.lang.String, int)' on a null object reference" error about secured-preference-store HOT 7 OPEN

Looks like the KeyStore instance was null when creating the EncryptionManager instance. May be the device doesn't have a AndroidKeyStore implementation. I'll try and see why is it throwing a NullPointerException when the expected would be a KeyStoreException or NoSuchProviderException.

Hello. I am facing the same stack trace from my apps. Did you get a clue how to make a workaround for it?

@texnedo I could not actually reproduce it on any devices that I have. Are you using the latest version of the library with the recovery handler? And the recovery handler is not getting invoked?

from secured-preference-store.

I don't use this library, but work with AndroidKeyStore directly. I was just googling to find any solution for my issue. What does this recovery handler do? Could you navigate me in your repo the place where I can find it?

@texnedo In that case the recovery handler wouldn't be very useful for you I guess as it doesn't solve the issue; just provides the library a way to start over.

@skhugh were you trying to access the secured preferences from a remote service? This error seems to be related to this:

Is there any better way to solve this problem. From firebase's crashlytics, we found a large number of crash logs of this type of problem.
