How to force Google Navigation to display only one route?

Question

Android

Inside my app, I'm running navigation from Google like this:

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?daddr=" + mCity));
intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
startActivity(intent);

Such a call should build a route from my current GPS location to the destination city. But often the application prompts me to choose one of several routes, as shown in the screenshot below. How can I force it to always display only one route, with no choice?
