I use Google Endpoints for my Android application. I want to upload an image to Blobstore:

Endpoint to get upload url:

@ApiMethod(name = "generateImageUploadUrl")
    public UploadUrl generateImageUploadUrl() {
        BlobstoreService blobstoreService =
                BlobstoreServiceFactory.getBlobstoreService();

        String blobUploadUrl = blobstoreService.createUploadUrl("/blob/upload");
        return new UploadUrl(blobUploadUrl); // UploadUrl is an inner class to store the url
    }

Code in Android app to upload image:

        HttpClient httpClient = new DefaultHttpClient();
        HttpPost postRequest = new HttpPost(url);
        MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
        try{
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 75, bos);
            byte[] data = bos.toByteArray();
            ByteArrayBody bab = new ByteArrayBody(data, "forest.jpg");
            reqEntity.addPart("picture", bab);

            postRequest.setEntity(reqEntity);
            HttpResponse response = httpClient.execute(postRequest);
            HttpEntity entity = response.getEntity();
            BufferedReader reader = new BufferedReader(new InputStreamReader(entity.getContent(), "UTF-8"));
            String sResponse;
            StringBuilder s = new StringBuilder();
            while ((sResponse = reader.readLine()) != null) {
                s = s.append(sResponse);
            }

            s.toString();
        }
        catch(Exception e){
            e.getCause();
        }

How do I get the final URL of the image?
