Failed to init Secured Preference Store. Exception: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String about secured-preference-store HOT 4 OPEN

couldn't reproduce this issue but 57f976c safeguards the code that might have caused this issue. @minadaki can you please try the latest code and see if it fixes the issue?

Hello,
Thank you for your fast reply.
Unfortunately, even with the latest version, the app still crashes.

The library fails to initialise:

Failed to init Secured Preference Store. Exception: java.lang.ArrayIndexOutOfBoundsException: length=1; index=1 at devliving.online.securedpreferencestore.SecuredPreferenceStore.<init>(SecuredPreferenceStore.java:76) at devliving.online.securedpreferencestore.SecuredPreferenceStore.init(SecuredPreferenceStore.java:134)

The actual crash takes place later when the app tries to use Secured Shared Preferences:

This is how I initialise the library:
private static final String SECURE_PREFS_NAME = "secPrefs"; private static final String SECURE_KEY_PREFIX = "testvss"; private static final byte[] SECURE_PREFS_SEED = "seed".getBytes(); SecuredPreferenceStore.init(getApplicationContext(), SECURE_PREFS_NAME, SECURE_KEY_PREFIX, SECURE_PREFS_SEED, new DefaultRecoveryHandler2());

Testing device:
Samsung S8, Android Oreo (8.0.0)

from secured-preference-store.

Haven't been able to reproduce this so far. Have you tested on any other device except the Samsung? @minadaki

from secured-preference-store.

I tried on a Motorolla phone running Android Oreo and it worked fine.
After that I uninstalled my app from the Samsung S8 phone and cleared all the app's cache and data.
Upon re-installing the app, the library initialised successfully and no crashes occurred.
So where does that leave us? If I upload a new version of my app in Playstore including the changes, will the app crash after updating or not? Does update of the app clear cache and data (simulating the uninstall-install scenario) ?
