07/15/2021, 10:21 AMhow can I receive image uri into my app? Do I need to receive Intent in my activity, and somehow send it to NavHost?

07/15/2021, 1:34 PMYou'll want to use the Activity Result APIs: https://developer.android.com/reference/kotlin/androidx/activity/compose/package-summary#rememberlauncherforactivityresult

07/15/2021, 1:35 PMthanks for answer, but maybe wasn't clear enough, sorry
I'm confused how to receive intent to my app, when using intent filter. So I can share image into my app. Basically this for compose.
I know I have to make deeplink in NavHost, but not completely sure how Uri should be passed to there. I guess I need to receive it in Activity, and somehow send it to composable destination.

07/15/2021, 1:45 PMYou don't need to do anything, NavHost will take care of that part for you
As long as you have the intent filter and deep link, that's all you need
When you are deep linked to a destination, you'll get another argument: https://developer.android.com/reference/androidx/navigation/NavController.Companion#KEY_DEEP_LINK_INTENT()
That argument has the full Intent

07/15/2021, 1:52 PMcool, thank you!
gonna try it out
do you mind helping me out a bit more? I'm confused how to create composable deeplink. How does this look to you:
Copy code
composable(
route = "myroute",
deepLinks = listOf(
navDeepLink {
uriPattern = "<app://com.app.myapp>" // ???
action = Intent.ACTION_OPEN_DOCUMENT
mimeType = "image/*"
}
)i

navDeepLinkuriPatternYour action and mime type should match the intent filter in your manifest - if you want to be in the share menu of other apps, that would be
ACTION_SENDp

Copy code
