I have such array:

var array: JsonArray? = JsonArray()

I would like to get its size in kb and mb also. I tried smth like this:

Singleton.array.toString().length.toString()

but it returns me 2 when I have empty array, so I decided that I did smth worng. Maybe someone has working way? I also saw this question.

First u need to getBytes and than convert it from there, length in your case is something totally different. – HyperX Oct 18 '19 at 13:27
I tried to get bytes but AS can't find such method so I decided that I can't get bytes from this array – Andrew Oct 18 '19 at 13:28
Because you are calling toString().length instead of toString().getBytes().length i guess – HyperX Oct 18 '19 at 13:32
no, this didn't help :( unresolved reference :(((( – Andrew Oct 18 '19 at 13:35
As you are using Kotlin this should be answer https://stackoverflow.com/questions/46701316/kotlin-equivalent-of-javas-string-getbytes – HyperX Oct 18 '19 at 13:44
The representation of an empty array is not an empty string, isn't it? – Jean-Baptiste Yunès Oct 18 '19 at 14:20
