KeyStore exception in log on Android 9 device #39

Open kfjtrifork opened 6 years ago

kfjtrifork commented 6 years ago

Thx for a great library. When running on a Android 9 device (Pixel) I see an error in the log. This happens both when target api is set to Android 9 (28) and earlier (tested with 26). This exception is not propagated to the calling app. This error does not occur when running older Android devices (tested on Android 8 and 6). I can't tell the severity of this error (the call to "KeyStore.entryInstanceOf" probably fails, which is part of an if statement) but hope you can :) BR, Kristian

Seeing the same error when using implementation 'online.devliving:securedpreferencestore:0.7.4'. Only on OS 9 devices.

Hi! Any news or feedback on this? I'm experiencing the same thing in Android 9.

Hi! Still I'm getting the same exception even after changing getKey() and getCertificate() methods instead of getEntry() in Android 9. Is there any updated solution on this?
