Update :

code :

public byte[] getUrlImgContent(String urlstring) throws IOException { byte[] imageRaw = null; URL url = new URL(urlstring); HttpURLConnection urlConnection = (HttpURLConnection) url .openConnection(); urlConnection.setUseCaches(false); urlConnection.connect(); if (urlConnection.getResponseCode() == HttpURLConnection.HTTP_OK) { try { InputStream in = new BufferedInputStream( urlConnection.getInputStream()); ByteArrayOutputStream out = new ByteArrayOutputStream(); int c; while ((c = in.read()) != -1) { out.write(c); } out.flush(); imageRaw = out.toByteArray(); urlConnection.disconnect(); in.close(); out.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return imageRaw; } return null; }
