Hello everyone. Anyone here got an idea why I can't launch this PendingIntent for Compose Navigation deeplinking from my Glance widget. I get android.app.PendingIntent$CanceledException when I execute the action.

PendingIntent code

internal fun openDeepLinkPendingIntent(context: Context, uriString: String): PendingIntent? {
    val intent = Intent(
        Intent.ACTION_VIEW,
        uriString.toUri()
    )
    return TaskStackBuilder.create(context).run {
        addNextIntentWithParentStack(intent)
        getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_IMMUTABLE)
    }
}

My ActionCallback:

class OpenTaskDetailsAction : ActionCallback {
    override suspend fun onRun(context: Context, glanceId: GlanceId, parameters: ActionParameters) {
        val taskId = parameters[PendingTasksWidgetParamKeys.TASK_ID_KEY]
        taskId?.let {
            val pendingIntent = openDeepLinkPendingIntent(context, it)
            println("Pending Intent is present: $pendingIntent")
            pendingIntent?.send()
        }
    }
}

More info: I am not directly passing the MainActivity in the Intent because it lives in a different module from the widgets. So I just registered an intent-filter inside the main app manifest file.

Never mind. I didn't properly format my URI.

Note, you are doing a launch trampoline here, by using the ActionCallback and then launching the activity.

You could directly pass the intent with the URI to the actionStartActivity(intent)

I figured that out after looking at the docs and used actionStartActivity instead. Though one slight problem with this, it doesn't create synthetic backstacks from a deeplink since we can't use TaskStackBuilder with normal activity intents. The end result is that we don't have the expected backstacks, the navigation up (back button at the top bar) that is linked to navController can't pop the stack to go back. Activities are just laid on top of each other, while leaving the main activity created from the launcher intent still active.

Unless there's something else I'm missing

[Marcel Pinto]

I don’t remember exactly how but you should be able to recreate the same behavior using some of the Intent flags and taskAffinity for your activities. Check https://developer.android.com/guide/components/activities/tasks-and-back-stack

[Racka N]

After reading this, I can stop multiple tasks and activities being launched over one another. Unfortunately, I still can't mimic what TaskStackBuilder does with compose-navigation since with actionStartActivity onNewIntent is called on a new instance of the activity and not the activity that's already on the stack even with FLAG_ACTIVITY_SINGLE_TOP

[Racka N]

Ok, just noticed some very strange behavior. Deeplinks to destinations that aren't in a nested graph (defined directly in the root graph instead of being inside navigation builder) create the expected backstacks and don't launch a new activity if it's already in the stack. But those inside navigation builder exhibit the behavior stated in the previous post.

Seems like an issue related to compose-navigation and not the Intents. Thank's for help, I'll investigate this further with regards to compose navigation.

👍 in the meantime feel free to open a FR in glance to create an action for pending intents. It should be fairly simple to add
