使用MapContainer的OutOfMemoryError

Question

在我的初始屏幕之后，我的主窗体包含一个MapContainer，在其中显示几个点。它在Simulator上运行良好。但是，在设备上，几秒钟后，电话仅挂起，应用程序崩溃。这与我添加多个点的方式有关系吗？我已经显示了下面的代码。我还添加了LogCat stackTrace。

public void addMarkers(MapContainer mc)
   {
       Vector v=  new Vector();
       try
       {
        Style s = new Style();
        s.setFgColor(0xff0000);
        s.setBgTransparency(0);
        FontImage markerImg = FontImage.createMaterial(FontImage.MATERIAL_PLACE, s, 7);
        EncodedImage ei = EncodedImage.createFromImage(markerImg, false);
        List lx = (List) Storage.getInstance().readObject("CASES");
        Coord c = null;
       for(Object m: lx)
       {
           Map p= (Map) m;
           c = new Coord(Double.parseDouble(p.get("latitude").toString()), Double.parseDouble(p.get("longitude").toString()));
           v.add(c);
           mc.addMarker(ei, c, "Hi marker", "Optional long description", new ActionListener() {
                public void actionPerformed(ActionEvent evt) {
                    ToastBar.showMessage("You clicked the marker", FontImage.MATERIAL_PLACE);
                }
            });
       }
       mc.fitBounds(BoundingBox.create(v));

       }catch(Exception er){er.printStackTrace();}       
   }

下面是我的LogCat strackTrace
