title: React native keychain error when using setGenericPassword function
body: <p>I am using <a href="https://www.npmjs.com/package/react-native-keychain" rel="nofollow noreferrer">keychain</a> package to store credentials. After I build the app this package doesn't work but throws an error.
  This is the error:</p>
  <pre><code>Attempt to invoke virtual method 'void com.oblador.keychain.cipherStorage.CipherStorageFacebookConceal.throwIfInsufficientLevel(com.oblador.keychain.SecurityLevel)' on a null object reference
  </code></pre>
  <p>The same code works fine when it is compiled on my friend's pc.
  SO, why is that?  We build the same app on the same phone and I got this error.
  How can I solve this?</p>
