Nodes are instructions, like "turn left at street xx", "turn right at road 
yy",... 
I've not tried your FROM/TO path, but having no instruction doesn't necessarily 
means there is an error. 
The right way to check errors is looking if Road.mStatus==STATUS_DEFAULT. 

If you really have an error, here is a good way to analyze what happens: look 
at the logcat, you will see the url sent: copy/paste it in a browser, and see 
how the answer look like.

I attached the code... Becouse the same example was working five days ago. I 
just put some markers un the map... Like tutorial 1. And it was working ok!! I 
tried to change from/to... But the result it's the same... I also copy the path 
from/to of your example in Paris and it doesn't work. So i decide to create an 
issue becouse it's really extrange...
Please if you have a minute, see the code... Thank you very much!!

I forgot... If you download your app example "OSMBonusPackDemo_v2.4.1.apk" it 
doesn't work either. The app draw the path but doesn't put the markers... 
Becouse the arrayList mNodes size = 0...

Oh my God, OSRM service has changed their input parameters! And their online 
doc has not been updated yet. 
I just fixed that, and published corrected jar and apk (v3.0, embarking some 
other minor improvements). I will commit OSRM source change very soon.

Me too... I have the same problem, I'm using the osmbonuspack_v4.4.jar library.
I don't know why road.mNodes.size() = 0 
but I have resolved changing road.mNodes.size() to road.mRouteHigh.size()
more exactly, replacing the original code (in Tutorial_1) with this code

Drawable nodeIcon = getResources().getDrawable(R.drawable.marker_node);
        for (int i=0; i<road.mRouteHigh.size(); i++){
                GeoPoint node = road.mRouteHigh.get(i);
                Marker nodeMarker = new Marker(map);
                nodeMarker.setPosition(node);
                nodeMarker.setIcon(nodeIcon);
                nodeMarker.setTitle("Step "+i);
                map.getOverlays().add(nodeMarker);
        }  

Thank you very much for your work

I have found a solution, you must put this code

StrictMode.ThreadPolicy policy = new StrictMode.
ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy); 

at the beginning of your main activity

this method is valid just in debug fase, but after this fase is better change 
it with an AsyncTask

The problem was try to connect in HTTPConnection mode inside of GUIThread
for that reason we need to define 

StrictMode.ThreadPolicy policy = new 
StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy); 

alternatively, we can declare an AsynTask to Connect in HTTPConnection mode
because the call 

Road road = roadManager.getRoad(waypoints);

uses HTTPConnection

Your analysis and solution are correct. 
You can also refer to the "Important note about network calls" in Tutorial_0.
