Hybrid app developer here (Apache Cordova). The work that I do is pretty close to web development + some hooks into native code (which is done by plugins) -- so your skills should transfer pretty readily.

The only headache that Donn eludes to that I've experienced had to do with Android's scoped storage. It's taken them a few tries to get it right, and their documentation hasn't really provided good best practices, so I've had to roll with the punches a few times. But I really haven't had to deal too much with Donn's other points.
