                HttpResponse response = httpclient.execute(httppost);
                final String the_string_response = convertResponseToString(response);


            }

Answer 1

To send more image in webservice. You have to change in webservice also. Add one more parameter in service part. so you can be able to send more than one image in one time.

and get the base64 string of second image like e.g. img_str2

like :

String image_str = Base64.encodeBytes(byte_arr);
String image_str2 = Base64.encodeBytes(byte_arr2);

and named new parameter in service like image2

 nameValuePairs.add(new BasicNameValuePair("image",image_str));
 nameValuePairs.add(new BasicNameValuePair("image2",image_str2));

Here image and image2 is 2 diff. parameter for images. these parameter names must also have to be define in your service side code.. so that service code can save your iamges.
