[Camera Plugin] should be installable on api 16+ even if it will not work #30854
Description
I saw that issue that is to make camera plugin compatible with api 16 and more #19083
My use case is a bit different and maybe easier to fix.
My app is compatible android 16+ and I need camera for a small feature. So I want to provide this feature only for android 21+. Problem is that the camera plugin doesn't allow me to compile and android 16 at all.
It should allow me to install it. As there will be no problem until I use it, which will be not the case as I'll check the android version to prevent this feature.
For now I'm getting:

If someone can tell me how fix this or what to change on the camera plugin I can do a PR for that.
