Hello! Does anyone tried to implement deeplinks with newer navigation type-safe args ? If so, any examples of how to do it? I left on the thread what I got so far 🧵

[Lisandro Di Meo]

composable<Route1>(
deepLinks = listOf( navDeepLink { uriPattern = "<example://compose/{id}>" } )
) {
   val (id) = it.toRoute<Route1>()
   Text(text = "Id is $id")
}

I've tried to launch this by running the command on adb shell am start -d "<example://compose/15>" -a android.intent.action.VIEW, and the intent filter is the following:

<data android:scheme="example" />
<data android:host="compose" />

But throws a serialization error 🤔

Now wouldn't it be helpful if we also knew what Route1 looked like?

[Lisandro Di Meo]

Indeed, I forgot to add it. Thanks:
data class Route1(val id: Int)

[Lisandro Di Meo]

I think I figured out how to do it, but perhaps there is another way

[Stylianos Gakis]

What did you try which did work?

[Lisandro Di Meo]

composable<Route1>(
             deepLinks = listOf(
                 navDeepLink { uriPattern = "<example://compose/{id}>" }
             )
         ) {
             val routeInstance = it.arguments?.getInt("id")?.run { Route1(this) } ?: it.toRoute()
             Text(text = "Route is $routeInstance")
         }

[Lisandro Di Meo]

I was looking to have a composable route that can be navigated from deeplinks and using a type safe route

[Lisandro Di Meo]

That worked, but I don't know if there is another way (more standard perhaps)

[Ian Lake]

You'll want to use the navDeepLink<Route1> API: https://androiddev.social/@ianlake/112599858226100367

[Lisandro Di Meo]

Amazing! Thanks Ian. Here's the result:

composable<Route1>(
    deepLinks = listOf(
        navDeepLink<Route1>("<example://compose/{id}>"),
    ),
) {
    val routeInstance = it.toRoute<Route1>()
    Text(text = "Route is $routeInstance")
}

Pretty sure the "basePath" is supposed to just be what it says, the base path, not to include anything about the args themselves. Here are some test which show examples of how it works https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:navigati[…]/java/androidx/navigation/NavDeepLinkBuilderTest.kt;l=135-156
Also take a look at the docs here https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:navigati[…]Fnavigation%2FNavDeepLinkDslBuilder.kt%20function:navDeepLink
So the {id} part in there looks wrong.

[Lisandro Di Meo]

Hm, I tried without the {id} and it didn't work. I'll take a look on that anyways
