KeyStore exception

[arcticfox1919]

My current version is 8.0.2.

I'm guessing this issue has not been fully fixed, or has created new problems?

The problem seems to be in this code(AndroidKeyStoreUtil.java:205):

try {
            final KeyStore keyStore = getKeyStore();
            final Certificate cert = keyStore.getCertificate(keyAlias);
            final Key privateKey = keyStore.getKey(keyAlias, null);
            if (cert == null || privateKey == null) {
                Logger.verbose(methodTag, "Key entry doesn't exist.");
                return null;
            }

            Logger.verbose(methodTag, "Key read from KeyStore");
            return new KeyPair(cert.getPublicKey(), (PrivateKey) privateKey);
        } 

You may be able to fix the problem with reference to this suggestion on stackoverflow.
