Deep linking's picked up popularity recently and I'm hoping to understand them a lot better sooner than later.
I've configured my app for deep linking and can open it from a deep link (testing on a local environment).
However, I can't know any information about /where/ the app was opened... or can I?
For example, if my users install my app, and they share a deep link on Facebook... I can't necessarily "force" them to include any parameters for tracking or analytics purposes!
So in this situation... I'm wondering, how can I know the page they shared it on? I want to get this data. Or is it just impossible? Or, as a last resort, will I have to just "guess" by say, checking what activity was switched out of before my app's activity was launched? (If it is possible...)
