Based on AirBnB's experience, now you need to find React Native devs in addition to Java devs.
From my experience with RN, you do need to get into the native bits, but most of the development will be not native. So the number of skilled native device engineers required should be less.
So you can’t be a startup/small shop if you want to do this well.
The ones I’ve known personally hated it so much they moved to backend or full stack jobs.
For that reason I thought that there would be way more Android devs. After all, a teenager with a regular computer can start developing Android apps and download the APK in a cheap Android device without paying anything.
On the other hand you mentioned _experienced_ native Android devs, while my thought applies more to junior Android devs, and maybe the two things don't correlate as well as expected.
