@adamduren any word on the README update? It just needs to be a short blurb pointing to the [Android lifecycle guide](http://cordova.apache.org/docs/en/latest/guide/platforms/android/lifecycle.html) really. Looking at the javascript code for this plugin, I don't really think there is any need for anything else. We just need to list the quirk and point to the documentation.

> I have been testing my app in low memory conditions by setting the android developer setting of "Don't keep Activities" which simulates low memory conditions. Every time I use the capture plugin for video when returning from the capture activity the app crashes. It appears that the state is not saved and on resume there are now null references such as the callbackContext and results array. It is fixed by using the onRestoreStateForActivityResult and onSaveInstanceState methods.
