推荐答案

我得到了解决 - 这里是答案：

I got the solution — here is the answer:

new Thread(new Runnable()
    {
        public void run() 
        {
            RoadManager roadManager = new OSRMRoadManager();
            ArrayList<GeoPoint> waypoints = new ArrayList<GeoPoint>();
            GeoPoint startPoint = new GeoPoint(source_lat, source_longi);               
            waypoints.add(startPoint);
            GeoPoint endPoint = new GeoPoint(desti_lat,desti_longi);
            waypoints.add(endPoint);                    
            try 
            {
                road = roadManager.getRoad(waypoints);
            } 
            catch (Exception e)
            {
                e.printStackTrace();
            }

            runOnUiThread(new Runnable() 
            {
                public void run() 
                {
                    if (road.mStatus != Road.STATUS_OK)
                    {
                          //handle error... warn the user, etc. 
                    }

                    Polyline roadOverlay = RoadManager.buildRoadOverlay(road, Color.RED, 8, context);
                    map.getOverlays().add(roadOverlay);                 
                }
            });
        }
    }).start(); 

和我使用的两个JAR文件： SLF4J-Android的1.5.8.jar 和 osmdroid-Android的4.2.jar 和 osmbonuspack 库。

And I am using two JAR files: slf4j-android-1.5.8.jar and osmdroid-android-4.2.jar, and osmbonuspack library.
