is there any way to to load a file other than `startActivity kotlinlang #compose

I think so, because that's the only way I know of which won't work in compose cus it doesn't use activities (which is required to use startActivityForResult)

am using something like that after all

Copy code

val context = +ambient(ContextAmbient)
context.startActivity(Intent(context, CustomActivityClass::class.java))

CustomActivityClass

has implemented

onActivityResult

which listens for a file

don't like the way I solved it cause will have to store the file as a global state but can't think of anything else

Load file from uri:

context.contentResolver.openInputStream(uri)?.use { it.readBytes() }

Why would you start new activity for that?

well it works nicely as long as you have the uri, the thing is how do I obtain it

it's my bad because I didn't mention it - I want to be able to pick a file from file browser (that's what I mean by

load a file

)

Maybe change question to "how to call other activity from Compose and get result".

Anyway, if anyone would like to launch a file picker, that's more or less it: https://pastebin.com/embed_iframe/DAgXkFi7 probably not the best solution as I'm new to android, but it gets the job done

isnt it written in kotlin nor using compose? I just assumed that there must be other, compose-specific way to do such thing (and by that I mean a component, like

TopAppBar

), turned out there is not even tho one would help

I'm not using anything compose specific in that pastebin snippet, but it's made for composable functions, you just have to provide context

Compose doesn't have a dedicated navigation solution yet, but we're planning to have one at some point
