Depends on case and constant name

[gildor]

For example if constant is hard coupled to enclosing class I would use compantion object, like Integer.MAX_VALUE, if constant is just some constant value, something like BUFFER_SIZE, I rather use top level constant

[gildor]

also, sometimes you want to group constants to have better discoverability, like:
View.GONE
View.VISBLE

So you can have VIEW_GONE and VIEW_VISIBLE, but companion object version looks better

Thanks for the explanation 👍

One more thing: For private constants I use top level declaration, no reason to use companion object for such case (the same syntax, additional unnecessary class)

[fatih.yalmanbas]

Same here, actually i think that’s the primary use of top level declaration. Or if you wanna share same const for different classes in same file (which is again a rare use-case)
