getSymmetricKey() is null

[eitanaviv]

Hi there,
After calling generateSymmetricKey() for the first time the user's runs the app, and when reopening the app i'm calling getSymmetricKey() everything seems to be working fine.
But when restarting the device, getSymmetricKey() return null and app stops working of course.
I'm using this library with Realm.

My code:

Store store = new Store(getApplicationContext());
        Crypto crypto = new Crypto(Options.TRANSFORMATION_SYMMETRIC);
        SecretKey key;

        if (!store.hasKey(getALString())) {
            freshStart = true;

            key = store.generateSymmetricKey(getALString(), null);
        } else {
            freshStart = false;

            key = store.getSymmetricKey(getALString(), null);
        }

The above code get called on: public class MyApplication extends MultiDexApplication

Appreciate the help.
