> If the cordova activity is suspended while waiting for a callback, it can be woken up in a state where the plugin which should be responsible for that callback is not present, and the app will throw a NullPointerException.
> There may be something deeper going on here, but we should probably not throw in any case -- at least we can restart in a stable state.
> From the original pull request (https://github.com/apache/cordova-android/pull/58):
> bq.I had a situation where the camera application would actually fail and it seems that the onActivityResult method would fall into an unusual state and throw an exception.
> bq.The simple fix was to ensure that if the plugin manager returned null for a callback, we didn't then attempt to use the callback.
