Track WebViews
Enable tracking in WebViews
Section titled Enable tracking in WebViewsWhere to inject your WebViews ?
Section titled Where to inject your WebViews ?It is essential that the following steps are done before an URL is loaded in your WebView. With that in mind, you should inject your webviews in onCreate()
in Activity and onCreateView()
in Fragment.
No matter where you decide to add the following injection code, keep in mind that it will not take effect until the next WebView content reload.
Inject a variable to detect when you load your page from a WebView
Section titled Inject a variable to detect when you load your page from a WebViewIf your page can be loaded both in a WebView and in a browser, you will need to differentiate both, in order to inject the proper CS Tag first.
You may have already set up a way to handle this differentiation. If not, here’s how to inject a variable to detect when the page is being loaded from a WebView, before adding our JavaScript Bridge.
val isWebViewJS = "window.isWebView = true;" val webView = findViewById<WebView>(R.id.webview) webView.settings.javaScriptEnabled = true webView.webViewClient = object : WebViewClient() { override fun onPageStarted(view: WebView?, url: String?, favicon: Bitmap?){ webView.evaluateJavascript(isWebViewJS){ _ -> } super.onPageStarted(view, url, favicon) } }
Inject the Bridge between the CS Tag in WebView mode and the SDK
Section titled Inject the Bridge between the CS Tag in WebView mode and the SDKUse the following API:
CsWebViewManager.injectEventTrackingInterface(@NonNull WebView webView) // to start tracking the specific WebView
It will inject our JavaScript Bridge in order to connect the CS Tag in WebView mode and our SDK.
Inject the CS Tag in WebView mode into your HTML page
Section titled Inject the CS Tag in WebView mode into your HTML pageAfter doing all the above, in order for the implementation to be completed, you will need to make sure our CS Tag in WebView mode is injected on your pages. To do so, refer to 📚 Mobile Apps WebView Tracking Documentation.
Let’s sum it up
Section titled Let’s sum it upLet’s illustrate our implementation with an Activity. In your onCreate()
method, you will add the following:
override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_web_view)
// Inject the variable to detect that you are in a WebView context val isWebViewJS = "window.isWebView = true;" val webView = findViewById<WebView>(R.id.webview) webView.settings.javaScriptEnabled = true webView.webViewClient = object : WebViewClient() { override fun onPageStarted(view: WebView?, url: String?, favicon: Bitmap?){ webView.evaluateJavascript(isWebViewJS){ _ -> } super.onPageStarted(view, url, favicon) } }
// Inject the Bridge between the CS Tag in WebView mode and the SDK CsWebViewManager.injectEventTrackingInterface(webView)
webView.loadUrl(DEFAULT_WEB_VIEW_CONTENT_URL) webView.reload() }
If you are using Fragments, the approach is similar, but should be done in the onCreateView()
method, as stated previously.
Validate your implementation of WebView tracking
Section titled Validate your implementation of WebView trackingCurrently, there is no way of validating the implementation on the native side only.
Validating the implementation on the web side
Section titled Validating the implementation on the web sideOnce you arrive on the screen with the tracked WebView, you should see an initial confirmation log message:
WebView detected and WebView tracking enabled on native side
Specific logs are then emitted for:
- Page views fired by the WebView Tracking Tag in the same format as for screen views:
Screenview - Screen name: {{page name given}} - Screen number: 11
- Taps and swipes detected by the WebView Tracking Tag in the same format as for defaults taps and swipe but with the target matching an HTML DOM element value:
Tap - Target: {Last view info: div:eq(0)} - Unresponsive: false
Going further: If you still have doubt, you can look for logs by filtering on WebViewEventProcessor
. Their presence will confirm that it is well implemented on both web and native sides.
