How to decode the image from json object?

Question

I am trying to post the image in Base64 format string to the web server. And I need to retrieve it back from the web server and decode it in Bitmap format so that I can display the image in listview.But I am getting the error while decoding. Please take a look at the code I've posted here..

Encoding:

ByteArrayOutputStream byteArrayBitmapStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, COMPRESSION_QUALITY, byteArrayBitmapStream);
byte[] b = byteArrayBitmapStream.toByteArray();
String encodedImage = MyBase64.encode(b);

Decoding:

byte[] byteArray =  Base64.decode(jsonObject.getString("imageData"), Base64.DEFAULT) ;
System.out.println("byte[]:"+byteArray);
Bitmap bmp1 = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

Here is the log:![Error showing in logcat]

hey u want to decode image from json object

then u first store image url in database and access by json

then than get bitmap image from url

use following code

try {
        URL url = new URL(url);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
