Illegal character in query in URL Connection

Question

I am trying to get JSON data from an URL and I have checked the URL via my browser, it's showing me valid JSON data whilst, if I do the same, I am getting the following error:

Illegal character in query at index 47: http://bangladeshelections.org/candidate?where={

index 47 is the first braces after where.

I have tried the following code to get the URL

here, value is an array from the previous activity.

 District = value[0]; Municipality = value[1]; Type = value[2]; Ward = value[3]; url_all_products = url_all_products + "District\":\""+District+"\",\"Municipality\":\""+ Municipality+"\",\"Type\":\""+Type+"\",\"Ward\":\""+Ward+"\"}"; Log.i("Monkey", url_all_products.charAt(47) + "bulls"); new LoadAllProducts(getApplicationContext()).execute();

The following code's are I am using to get JSON data in an Async Thread

 URL url = new URL(url_all_products); HttpClient client = new DefaultHttpClient(); HttpGet request = new HttpGet(); request.setURI(new URI(url_all_products)); HttpResponse response = client.execute(request); BufferedReader in = new BufferedReader(new InputStreamReader(response.getEntity().getContent())); StringBuffer sb = new StringBuffer(""); String line=""; while ((line = in.readLine()) != null) { sb.append(line); break; } in.close(); return sb.toString();

Thank you.

That is an illegal character in a query string. URLEncode your query string. — pvg

Your query string uses illegal characters - the easiest way to avoid this without external libraries is to use java.net.URI to construct your URL from its components. It includes a constructor that accepts a query string and will perform the proper encoding for you. For example to encode:

http://host.com/path?query=queryparam#fragment

new URI("http", "host.com", "/path/", "query=queryparam", "fragment").toURL();

See the docs at

http://docs.oracle.com/javase/6/docs/api/java/net/URI.html

no, you use URL and construct the whole thing just by adding strings together. java.net.URI is a different class.
Can you please give me an example with this situation? I am sorry but I did not get how to do so. I am stucked for a while now.
i edited it, please read the docs and at least try it, i'm not really going to write your code for you
