POBlackberry: opening ConnectionFactory too many times?
text
Body
copied!<p>I'm not entirely sure how to use ConnectionFactory properly, but here is my ImageThread example which invokes ConnectionFactory every time there is an image, which there are a bunch on any given screen.</p> <pre><code>public class ImageThread extends Thread { private String url; private HttpConnection httpConn; private InputStream is; private JSONArray array; private Bitmap image; private ImageThreadCallback c; private static boolean hasImageCache = false; private static MultiMap imageCache; public ImageThread(String url, ImageThreadCallback c, String ident){ System.out.println("Connection begin!"); this.url = url; this.c = c; } public void notifyUs(){ this.c.update(image); } public void run(){ myConnectionFactory connFact = new myConnectionFactory(); ConnectionDescriptor connDesc; connDesc = connFact.getConnection(url); System.out.println("Connection factory!"); if(connDesc != null) { System.out.println("Connection not null!"); httpConn = (HttpConnection) connDesc.getConnection(); try { httpConn.setRequestMethod(HttpConnection.GET); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } is = null; try { final int iResponseCode = httpConn.getResponseCode(); UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() { System.out.println("Connection in run!"); // Get InputConnection and read the server's response InputConnection inputConn = (InputConnection) httpConn; try { is = inputConn.openInputStream(); System.out.println("Connection got inputstream!"); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } byte[] data = null; try { data = IOUtilities.streamToBytes(is); System.out.println("Connection got data!"); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } EncodedImage hai = EncodedImage.createEncodedImage(data, 0, data.length); image = hai.getBitmap(); notifyUs(); } }); } catch(IOException e) { System.err.println("Caught IOException: " + e.getMessage()); } } } } </code></pre> <p>I know the example is the same as the examples, but should ConnectionFactory be called every instance of ImageThread? I ask this question because my app all of a sudden loses connection, randomly, while using it. The input/output icon ceases to flicker. I'm thinking it could be a misuse of ConnectionFactory? </p> <p>Any ideas?</p>
