Best way to scrape data from an App without Modifying it?

I'm trying to find a way to scrape data from an Android app on a large scale, ideally legally. I've been an Android Dev for about 12 years now, and this is the first time I've jumped into something like this.

I don't want to modify the Android App. I'm thinking that it's possible for me to take one of the open source emulators, modify it so that all apps are debuggable and hide the fact that it's an emulator. Ideally I'd like to dump the UI and extract the text that I'm looking for, but if that's not sufficient, maybe I can peak at the network traffic coming in and out?

1. Has anyone else done this?
2. Am I reinventing the wheel here? Is there a better way to do this already?
3. Any advice / tips?
