I'm interested in this too, I remember having it, or something like it. 

Who do you assume the other app is using onNewIntent? It seems like that should be up to the OS to determine which one to call? AFAICR Android is responsible for calling onCreate in response to your activity not existing. Remember your app is more than an activity. It may have zero or many activities. 

What I do remember is working in QtActivity and QtApplication to provide Android support. I think my issue was with Alarm manager or push notifications...
