Question

 connection = (HttpURLConnection) new URL(params[0]).openConnection();
 connection.setRequestProperty("Cookie", mCookiesList.get(0) + ";" + mCookiesList.get(1));
 connection.connect();
 BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream()));

`

Further to that, `BufferedReader` is for reading text files. An image is a binary file, so that class would not be an appropriate choice. — Joe C, May 20 '17 at 06:38
so what to do to get an image file i m passing a url its getting imageview so how do i get it — VENKATESH PACHAKOLLA, May 20 '17 at 06:42
you have `connection.getInputStream()` so use it directly for `Bitmap` decoding (by means of `BitmapFactory` class) — pskink, May 20 '17 at 07:11

You can use javax.imageio.ImageIO class to construct a BufferedImage having an InputStream :

BufferedImage bufferedImage = ImageIO.read(connection.getInputStream());

Then, if you are going to write is to disk as a bitmap :

int imageWithInPixels = 200;
int imageHeightInPixels = 200;
BufferedImage bitmapImage = new BufferedImage(imageWithInPixels , imageHeightInPixels , BufferedImage.TYPE_INT_RGB);
bitmapImage.getGraphics().drawImage(
    bufferedImage , 0, 0, imageWithInPixels , imageHeightInPixels , null);
ImageIO.write(bitmapImage , "BMP", new File("filename.bmp"));
