Library to record user interaction with my app

I have a small app. And for testing, I want to record what people do in the app. What I mean, I would like to log every button press, swap etc in my app, so later I can do most popular "scenarios" using UIautomator for testing.

Is there any library for that? I have tried Google, but there was only some B2B company, and UIautomator uses adb for capturing events.
