Description

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.
