What's the differences between me using lateinit var and by lazy, for stuff that gets init'd after create (), like Android, games etc

sreich: by lazy initializes the field on first access (according to the function passed), whereas lateinit must be initialized/assigned explicitly

Effectively though it's the same especially for short statements

I think especially for things like android, you would use lateinit when the time of initialization is dependent on external circumstances (availability of contexts e.g.) whereas bylazy could be used anytime, but is simply made lazy to reduze initialization time

lateinit

is

var

!

i am aware that lateinit is var, I mostly use it for fields which require a context in their constructor for example and therefor are assigned in

onCreate

lazy shouldn't be used when the lazy-block is dependent on the state of the containing object because it isn't really determined when it is called by design (you have to be aware in your code). but aside from this you could use it any other time. But I would not use it everytime because there is still some overhead of lazy to direct initialization, depends on use case
