Issue in making http call in android due to String format - illegal character in query at index 81

In my application, I have to get the data from JSON service based on TYPE and SUB TYPE selected by user and show the data to user.

I know how to make an http request, how to parse the response, but the URL is creating an issue.

The URL is like this:

http://abc.abc.ab.abc/myappnameapiii/index.php/Api/getAllInfoctoryUser_type?data={"type":"TYP","sub_type":"SUB"}

I tried escaping the " with StringEscapeUtils. But that didn't help.

Sample code:

String baseUrl = "http://abc.abc.ab.abc/myappnameapiii/index.php/Api/getAllInfoctoryUser_type?data={";
String typeInfo = "\"type\":\""+selectedType+"\",\"sub_type\":\""+selectedSubType+"\"}";
typeInfo = StringEscapeUtils.escapeJava(typeInfo);
String finalUrl = baseUrl + typeInfo;

//Call asynctask using finalUrl
....
....

I am getting this exception when I make an http request:

java.lang.IllegalArgumentException: Illegal character in query at index 81: http://abc.abc.ab.abc/myappnameapiii/index.php/Api/getAllInfoctoryUser_type?data={\"type\":\"TYP\",\"sub_type\":\"SUB\"}

Here is what I tried for resolving this:

First:

I tried unescaping the typeInfo just before I make a call in my AsyncTask like this:

try {
        String finalUrl = baseUrl.concat(typeInfo);*/
        String finalUrl = StringEscapeUtils.unescapeJava(url[0]);
        object = RestJsonClient.connect(finalUrl);
    } catch (Exception e) {
        e.printStackTrace();
    }

This doesn't help. It throws exception as:

java.lang.IllegalArgumentException: Illegal character in query at index 81: http://abc.abc.ab.abc/myappnameapiii/index.php/Api/getAllInfoctoryUser_type?data={"type":"TYP","sub_type":"SUB"}

Second:

Referring this question I tried using UTF-8 encoding according to answer on that post.

Code snippet:

String baseUrl = url[0];
String typeInfo =  URLEncoder.encode(url[1], "UTF-8");

String finalUrl = baseUrl.concat(typeInfo);
//String finalUrl = StringEscapeUtils.unescapeJava(url[0]);
object = RestJsonClient.connect(finalUrl);

Here, I passed the URL to asynctask in two Strings instead of one finalUrl string.

This also throws exception such as:

java.lang.IllegalArgumentException: Illegal character in query at index 81: http://abc.abc.ab.abc/myappnameapiii/index.php/Api/getAllInfoctoryUser_type?data={%5C%22type%5C%22%3A%5C%22MANUFACTURER%5C%22%2C%5C%22sub_type%5C%22%3A%5C%22GOLD%5C%22%7D

I am clueless regarding what to do now. It would be great if someone can help.

P.S: The same url shows the result in browser. The url is correct and data is there on server.

EDIT

According to @Tejas's comment, I tried passing the data in a POST request's body like this:

    List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add(new BasicNameValuePair("type", "TYP"));
    params.add(new BasicNameValuePair("sub_type", "SUB"));
    //request.setEntity(new UrlEncodedFormEntity(params));

    object = RestJsonClient.post( baseUrl, params);

Code of RestJsonClient.post method is working fine in my other calls. So I am not posting all of the code here. The snippet from that method after I get the response is:

    HttpEntity httpentity = response.getEntity();

    if (httpentity != null) {
        InputStream instream = httpentity.getContent();
        String result = convertStreamToString(instream);
        System.out.println("result: " + result);
        json = new JSONObject(result);
        instream.close();
    }

Now there is no error. I get response from the service with status code OK (200). But no data in result.

08-10 10:33:42.150 7003-7003/pkg.name W/System.err: org.json.JSONException: No value for data

Its not possible for me to request the change in service if its required. Can someone help me with passing parameters properly in GET request?
