Android 使用 Jetpack Compose 的深层链接导航到可组合项

当用户在我们的应用程序中输入地理围栏时，我们会向他们显示一个关于该区域的报价通知，单击该通知时，应将他们 bootstrap 到一个名为SingleNotification的特定可组合屏幕.我一直在关注google的codelab和documentation，但我还没有成功地导航到特定的屏幕.现在，单击通知或运行adb shell am start -d “eway://station_offers/date_str/www.test.com/TITLE/CONTENT” -a android.intent.action.VIEW命令即可打开应用程序.

该活动在 list 中声明如下:

    <activity
        android:name=".MainActivity"
        android:exported="true"
        android:label="@string/app_name"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
        </intent-filter>

        <intent-filter>
            <action android:name="android.intent.action.VIEW" />

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data
                android:host="station_offers"
                android:scheme="eway" />
        </intent-filter>
    </activity>

我们的MainNavController类包含NavHost，而NavHost又包含各种NavGraph.我只包括以下相关图表:

        NavHost(
            navController = navController,
            startDestination = NavigationGraphs.SPLASH_SCREEN.route
        ) {
....
            notificationsNavigation()
....    
    }

notificationsNavigation图定义如下:

fun NavGraphBuilder.notificationsNavigation() {
    navigation(
        startDestination = Screens.NOTIFICATION_DETAILS.navRoute,
        route = NavigationGraphs.NOTIFICATIONS.route
    ) {
        composable(
            route = "${Screens.NOTIFICATION_DETAILS.navRoute}/{date}/{imageUrl}/{title}/{content}",
            arguments = listOf(
                navArgument("date") { type = NavType.StringType },
                navArgument("imageUrl") { type = NavType.StringType },
                navArgument("title") { type = NavType.StringType },
                navArgument("content") { type = NavType.StringType }
            ),
            deepLinks = listOf(navDeepLink {
                uriPattern = "eway://${Screens.NOTIFICATION_DETAILS.navRoute}/{date}/{imageUrl}/{title}/{content}"
            })
        ) { backstackEntry ->
            val args = backstackEntry.arguments
            SingleNotification(
                date = args?.getString("date")!!,
                imageUrl = args.getString("imageUrl")!!,
                title = args.getString("title")!!,
                description = args.getString("content")!!
            )
        }
    }
}

Screes.NOTIFICATION_DETAILS.navRoute对应notification_details的值.

在geo fence广播接收器内，我构建了如下待定意图:

                        val deepLinkIntent = Intent(
                            Intent.ACTION_VIEW,
                            "eway://station_offers/${
                                offer.date
                            }/${
                                offer.image
                            }/${offer.title}/${offer.content}".toUri(),
                            context,
                            MainActivity::class.java
                        )
                        val deepLinkPendingIntent: PendingIntent =
                            TaskStackBuilder.create(context!!).run {
                                addNextIntentWithParentStack(deepLinkIntent)
                                getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT)!!
                            }
                        showNotification(offer.title, offer.content, deepLinkPendingIntent)

我想不出我在这里遗漏了什么.
