Automatic Screen Tracking in Kotlin SDK Alpha

This guide walks you through the automatic screen tracking feature available in the Kotlin SDK.

Overview

The Kotlin SDK provides a setNavigationDestinationsTracking API for automatically tracking user navigation within your Android application by leveraging a NavController.

The API listens to any screen changes and sends the corresponding screen events to RudderStack.

Workflow

• The setNavigationDestinationsTracking API utilizes OnDestinationChangedListener to detect any navigation changes.
• It also integrates with the onStart lifecycle callback of the user activity to ensure screen events are captured when the app is foregrounded or when any configuration changes occur.
• If multiple NavController instances are used in the Android app, you must call this API separately for each instance.

Usage

This section explains how to use the setNavigationDestinationsTracking API depending on your app setup:

Jetpack Compose navigation

If your app uses Jetpack Compose with NavController, you can set up the navigation tracking as follows:

@Composable
fun MyApp() {
    val navController = rememberNavController()

    LaunchedEffect("first_launch") {
        analytics.setNavigationDestinationsTracking(navController, this@MainActivity)
    }

    MyNavHost(navController = navController)
}

Fragments navigation

If your app uses Fragments with the navigation component, use the following setup in MainActivity:

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        val binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)

        val navHostFragment = supportFragmentManager
            .findFragmentById(R.id.nav_host_fragment) as NavHostFragment
        val navController = navHostFragment.navController

        analytics.setNavigationDestinationsTracking(navController, this@MainActivity)
    }
}
