   *    This would occur when end-users are running an older binary version than
   *    is available, and CodePush is making sure they don't get an update that
   *    potentially wouldn't be compatible with what they are running.
   * 3) The server said there is an update, but the update's hash is the same as
   *    the currently running update. This should _never_ happen, unless there is a
   *    bug in the server, but we're adding this check just to double-check that the
   *    client app is resilient to a potential issue with the update check.
   * 4) The server said there is an update, but the update's hash is the same as that
   *    of the binary's currently running version. This should only happen in Android -
   *    unlike iOS, we don't attach the binary's hash to the updateCheck request
   *    because we want to avoid having to install diff updates against the binary's
   *    version, which we can't do yet on Android.
