    <p>I am using TimerTask and ImageLoader class to load n image to an image item. </p> <pre><code>public class Imageloader implements Runnable{ private ImageItem item=null; private String url=null; /* * initializes the imageItem */ public Imageloader(ImageItem item,String url){ this.item=item; this.url=url; } private Image getImage(String url) throws IOException { item.setLabel(item.getLabel()+12); System.out.println("Test 5"); HttpConnection connection = null; DataInputStream inp = null; int length; byte[] data; try {System.out.println("Test 6"); connection = (HttpConnection) Connector.open(url); item.setLabel(item.getLabel()+13); connection.getResponseMessage(); System.out.println("Test 7"); length = (int) connection.getLength(); item.setLabel(item.getLabel()+14); System.out.println("Length is "+length); System.out.println("Test 8"); data = new byte[length]; inp = new DataInputStream(connection.openInputStream()); item.setLabel(item.getLabel()+15); System.out.println("Test 9"); inp.readFully(data); item.setLabel(item.getLabel()+16); System.out.println("Test 10"); return Image.createImage(data, 0, data.length); } finally { if (connection != null) connection.close(); if (inp != null)inp.close(); } } public void run() { System.out.println("Test 1"); Image image=null; try{ if (url!=null){ System.out.println("Test 2"); image=getImage(url); System.out.println("Test 3"); item.setImage(image); item.setLabel(item.getLabel()+17); System.out.println("Test 4"); } else{ item.setAltText("Map address specified is incorrect"); } } catch(IOException e){ item.setAltText("Map cannot be loaded now"); } } } public class MapTimer extends TimerTask{ DatagramConnection connection=null; String message=null; Imageloader imageretriever; ImageItem item=null; MapTimer (DatagramConnection connection,String message,ImageItem Img_map ){ this.connection=connection; this.message=message; this.item=Img_map; item.setLabel(item.getLabel()+1); System.out.println("Map is initizlized..."); } public void run() { System.out.println("Map starting..."); item.setLabel(item.getLabel()+2); String serverquery=null; try { item.setLabel(item.getLabel()+3); sendMessage(message); item.setLabel(item.getLabel()+4); //serverquery=receiveMessage() ; item.setLabel(item.getLabel()+5); //item.setLabel(" Loading...." ); //formatmessage(serverquery); String url="http://maps.google.com/maps/api/staticmap?center=Brooklyn+Bridge,New+York,NY&amp;zoom=14&amp;size=512x512&amp;maptype=roadmap"+ "&amp;markers=color:blue|label:S|40.702147,-74.015794&amp;markers=color:green|label:G|40.711614,-74.012318"+ "&amp;markers=color:red|color:red|label:C|40.718217,-73.998284&amp;sensor=false"; Imageloader Im=new Imageloader(item,url); item.setLabel(item.getLabel()+6); (new Thread(Im)).start(); item.setLabel(item.getLabel()+7); System.out.println("server map query is::: "+serverquery); } catch (IOException ex) { System.out.println("Error2"+ex); } catch(Exception e){ System.out.println("Error3"+e); } } /* * Sends a message via UDP to server */ private void sendMessage(String message) throws IOException{ Datagram packet_send=null; if (connection != null){ byte[] packetsenddata=message.getBytes(); packet_send = connection.newDatagram(packetsenddata,packetsenddata.length); connection.send(packet_send); packet_send = null; } } } </code></pre> <p>This is how I set the Timer;</p> <pre><code> MapTimer maptimer=new MapTimer (connection,mapquery ,Img_map ); Timer timer=new Timer(); timer.schedule(maptimer, 5000, 100000); </code></pre> <p>It's working fine with the enulator but as I deploy it on my mob,the image is not loading.. The image label is somewhat like <code>Stopping 234567234567</code> which implies that my timer is running fine. It is not entering the ImageLoader class... How do get to load this image?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
