This is duplicated in PhysicalWebShareActivity. It would be nice to find a way
to share it, or at least the part that creates the Intent. Maybe add it as a
static method in PhysicalWebBroadcastService?

Done.

+        Intent intent =
+                new Intent(ContextUtils.getApplicationContext(), PhysicalWebBroadcastService.class);
+        intent.putExtra(PhysicalWebBroadcastService.DISPLAY_URL_KEY, url);
+        startService(intent);
+    }
+}
