TWA Deeplink Param Tracking

//Deeplinks should work, as the LauncherActivity is prepared to handle them. Having said that, when starting the application from a deep link the parameter identifying the traffic coming from the Trusted Web Activity won't be appended (eg: &twa=1). So, the traffic coming into the application from a deep link is likely to be counted as regular mobile traffic.
it is possible to modify the LauncherActivity to append "&twa=1" in deep links, with something like this:

public class CustomQueryStringLauncherActivity extends LauncherActivity {
    @Override
    protected Uri getLaunchingUrl() {

        // Get the original launch Url.
        Uri uri = super.getLaunchingUrl();

        // Append the extra parameter to the launch Url
        return uri
                .buildUpon()
                .appendQueryParameter("twa", "1")
                .build();
    }
}
