I just tried the Demo application with an Android 4.0.3 AVD
=> no crash, the app loads and display the road exactly as on previous Android 
versions!

Very strange. 

Could you download and try the OSMBonusPackDemo app on your emulator?

Could you tell which osmdroid and osmbonuspack versions you use?

And could you provide your source code?

Thanks

osmdroid 3.0.8
osmbonuspack 2.1

Code:

package com.test.android;

import java.util.ArrayList;

import org.osmdroid.bonuspack.routing.OSRMRoadManager;
import org.osmdroid.bonuspack.routing.Road;
import org.osmdroid.bonuspack.routing.RoadManager;
import org.osmdroid.tileprovider.tilesource.TileSourceFactory;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;
import org.osmdroid.views.overlay.PathOverlay;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {
        private MapView map;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        map = (MapView) findViewById(R.id.mapview);
        map.setTileSource(TileSourceFactory.MAPNIK);
        GeoPoint startPoint = new GeoPoint(48.13, -1.63);
        MapController mapController = map.getController();
        mapController.setCenter(startPoint);
        mapController.setZoom(15);

        RoadManager roadManager = new OSRMRoadManager();
        ArrayList<GeoPoint> waypoints = new ArrayList<GeoPoint>();
        waypoints.add(startPoint);
        waypoints.add(new GeoPoint(48.4, -1.9)); //end point

        Road road = roadManager.getRoad(waypoints);

        PathOverlay roadOverlay = RoadManager.buildRoadOverlay(road, map.getContext());
        map.getOverlays().add(roadOverlay);
        map.invalidate();

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

}

I found. Look at: 
http://developer.android.com/reference/android/os/NetworkOnMainThreadException.h
tml

Basically, from SDK 3.0, we can't do network calls in the main thread. 

I didn't got the issue on OSMBonusPackDemo because 1/ It targets an earlier SDK 
version, and 2/ all network calls in the demo are done in threads (async 
tasks). 

You have 2 solutions: 
- Give to your project a target SDK version earlier than 3.0 (even if the 
emulator or phone used is > 3.0)
- Do the calls in threads => looking at the source code of the demo app could 
help you. 

I will add a note about that issue in the tutorials.
