After doing what Pratheep has suggested below, I recommend reviewing the following:
Here's something else to keep in mind. Is the mobile app report suite going to eventually going to handle both Mobile AND web traffic? If so, you may need to think through exactly how you want to map your Marketing Channels as well. Also, Mobile apps handle campaign traffic differently than browsers, particularly deeplinks, and the like, so you will need to understand how to set up the rules to identify this kind of traffic.
Following the guides and reading the blogs that Pratheep has touched on will definitely get you started. There are more of us here to help you out when you run into more questions.
Thanks, Jeff. I will def. read those resources. You asked the right question in your response so I will narrow my ask.
I am looking to understand how to set up marketing channels for the app only (setting up rules for deeplinks vs. tracking code for browsers). The app uses a separate report suite from the website (browser tracking).
