ArcGIS调用离线地图

[Cactus_hxk]

想做一个Arcgis调用离线地图用例，可怎么也不行，忘大神们帮帮忙啊，
代码如下：

private MapView mapView = null;
    private ArcGISLocalTiledLayer local = null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        /*
        this.mapView = (MapView)this.findViewById(R.id.map);//设置UI和代码绑定
        String strMapUrl="http://map.geoq.cn/ArcGIS/rest/services/ChinaOnlineCommunity/MapServer";
        ArcGISTiledMapServiceLayer arcGISTiledMapServiceLayer = new ArcGISTiledMapServiceLayer(strMapUrl);
        this.mapView.addLayer(arcGISTiledMapServiceLayer);
        */
        String pathName = getSDPath()+"/arcgis/neimeng/Layers";
        try
        {
            String inPath = Environment.getExternalStorageDirectory().getPath();
            List<String> outPath = getExtSDCardPath();
            Log.d("aaaaa","onCreate:++++++++++++++++++"+outPath.size());
            for(String s : outPath){
                Log.d("aaaaa","onCreate:++++++++++++++++++"+s);
            }
            Log.d("aaaaa","onCreate: ------------------------------------"+inPath);
            File f=new File(pathName);
            if(f.exists())
            {
                Log.d("","onCreate: ------------------------------------"+f.exists());
                local = new ArcGISLocalTiledLayer("file://"+pathName);
                mapView.addLayer(local);
            }

        }
        catch (Exception e)
        {

        }

        }

执行到这句时就报：local = new ArcGISLocalTiledLayer("file://"+pathName);
报错信息如下：
