    copied!<p>I'm trying to download an image from server and save the image on mobile phone.I'm able to download the image but I need to resize the image and then store the image to mobile.</p> <p>the code is like this.</p> <pre><code>public void requestPlatform(String strURL) throws IOException { try { System.out.println("requestPlatform"); byte [] imageBytes = null; if ((im = getImage1(strURL)) != null) { im=resizeImage(im, width, height); if(im!=null) { System.out.println("Image"); } else System.out.println("NoImage"); imageBytes=get_Byte_Array(im); fileCon=(FileConnection)Connector.open("file:///root1/photos/diwali1.jpg",Connector.READ_WRITE); fileCon.create(); if(fileCon.exists()) { System.out.println("File created"); } else { System.out.println("File not created"); } out = fileCon.openDataOutputStream(); if(imageBytes!=null) { out.write(imageBytes, 0, imageBytes.length); } if(out!=null) { out.close(); } if(fileCon!=null) { fileCon.close(); } im2=Image.createImage(imageBytes, 0, imageBytes.length); canvas.repaint(); } } catch (Exception e) { System.err.println("Msg: " + e.toString()); } } public byte[] get_Byte_Array(Image img) { int[] imgRgbData = new int[img.getWidth() * img.getHeight()]; byte[] imageData2 = null; try { img.getRGB( imgRgbData, 0, img.getWidth(), 0, 0, img.getWidth(), img.getHeight() ); } catch( Exception e ) { } ByteArrayOutputStream baos = new ByteArrayOutputStream(); DataOutputStream dos = new DataOutputStream( baos ); try{ for( int i = 0; i &lt; imgRgbData.length; i++ ) { dos.writeInt( imgRgbData[i] ); } imageData2 = baos.toByteArray(); baos.close(); dos.close(); }catch(Exception e) { } return imageData2; } </code></pre> <p>The problem is when I'm trying to resize the image and then save it on phone it just creates a file but there is no image.So i think there is some mistake while i'm converting image to byteArray.</p>
