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?

Use URLEncoder to encode your URL parameter strings.

Encode your typeInfo and the { preceding it.
