Image issue on ANDROID 2.2

Question

Hi All,

I have downloaded image from web and displayed in imageview,which works fine in Emulator and device.when i supposed to run on android 2.2 real device ,it throws null pointer Exception. what is the reason? I have used the following code..

public Bitmap downloadImage(String url) { Bitmap bm = null; try { URL myURL = new URL(url); final BufferedInputStream bis = new BufferedInputStream(myURL .openStream(), 1024); final ByteArrayOutputStream dataStream = new ByteArrayOutputStream(); BufferedOutputStream out = new BufferedOutputStream(dataStream, 1024); copy(bis, out); out.flush(); final byte[] data = dataStream.toByteArray(); BitmapFactory.Options bfo = new BitmapFactory.Options(); bfo.inSampleSize = 2; bm = BitmapFactory.decodeByteArray(data, 0, data.length, bfo); bis.close(); } catch (Exception e) { } return bm; }

static final int BUFF_SIZE = 1024;
static final byte[] buffer = new byte[BUFF_SIZE];

public static void copy(BufferedInputStream in, BufferedOutputStream out)
        throws IOException {
    try {
        while (true) {
            synchronized (buffer)
                                       {
                int amountRead = in.read(buffer);
                if (amountRead == -1) {
                    break;
                }
                out.write(buffer, 0, amountRead);
            }
        }
    } catch (Exception e) {
        if (in != null) {
            in.close();
        }
        if (out != null) {
            out.close();
        }
    } finally {
        if (in != null) {
            in.close();
        }
        if (out != null) {
            out.close();
        }
    }
}
