Body
I am using below code to display image from url comming from webservice. I am not getting any error but also not able to display the image. getWebData is a static method in my Utils class: <pre><code>public static void getWebData(final String url, final WebDataCallback callback) throws IOException { Thread t = new Thread(new Runnable() { public void run() { HttpConnection connection = null; InputStream inputStream = null; try { connection = (HttpConnection) Connector.open(url, Connector.READ, true); inputStream = connection.openInputStream(); byte[] responseData = new byte[10000]; int length = 0; StringBuffer rawResponse = new StringBuffer(); while (-1 != (length = inputStream.read(responseData))) { rawResponse.append(new String(responseData, 0, length)); } int responseCode = connection.getResponseCode(); if (responseCode != HttpConnection.HTTP_OK) { throw new IOException("HTTP response code: " + responseCode); } final String result = rawResponse.toString(); UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() { callback.callback(result); } }); } catch (final Exception ex) { UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() { callback.callback("Exception (" + ex.getClass() + "): " + ex.getMessage()); } }); } finally { try { inputStream.close(); inputStream = null; connection.close(); connection = null; } catch(Exception e){} } } }); t.start(); } </code></pre> The WebBitmapField that makes use of the getWebData method is below. All you need to do is pass a URL to the constructor and it'll load the image: <pre><code>public class WebBitmapField extends BitmapField implements WebDataCallback { private EncodedImage bitmap = null; public WebBitmapField(String url) { try { Util.getWebData(url, this); } catch (Exception e) {} } public Bitmap getBitmap() { if (bitmap == null) return null; return bitmap.getBitmap(); } public void callback(final String data) { if (data.startsWith("Exception")) return; try { byte[] dataArray = data.getBytes(); bitmap = EncodedImage.createEncodedImage(dataArray, 0, dataArray.length); setImage(bitmap); } catch (final Exception e){} } } </code></pre>

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.
