Converting BufferedReader to JSONObject or Map

InputStream inputStream = connection.getInputStream();

BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
    StringBuilder builder = new StringBuilder();
    String line;
    while ((line = bufferedReader.readLine()) != null) {
        builder.append(line + "\n");
        }

JSONArray jsonArray = new JSONArray(builder.toString());
for (int i = 0; i < jsonArray.length(); i++) {
     JSONObject json = jsonArray.getJSONObject(i);

    if (!json.get("object").equals(null)) {
        JSONArray objectJsonArray = json.getJSONArray("object");
            for (int i = 0; i < objectJsonArray.length(); i++) {
                JSONObject json = objectJsonArray.getJSONObject(i);     
            }       
    }
}

Hope it helps.

And what about this:

BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
JsonReader reader = Json.createReader(in);
JsonObject object = reader.readObject();
String s = object.toString();

First do it as string. you can use custom librarys for that like

 String message = org.apache.commons.io.IOUtils.toString(rd);

or a StringBuilder

    StringBuilder sb = new StringBuilder();

    String line;
    br = new BufferedReader(new InputStreamReader(is));
    while ((line = br.readLine()) != null) {
        sb.append(line);
    }

Then you can parse it. Since it's an object because of the "{" (array begin and ends with []) you need to create an JSONObject.

JSONObject json = new JSONObject(sb.toString());

then you can access your elements with

//{ "status": "ERROR", "errorCode": "MISSING_PARAMS", "errorMessage": null, "requestId": "20141014181739_11625805172", "downstreamModuleErrorCode": null, "object": [ "activity_code", "activity_name", "points", "frequency", "strategy", "vsa_app_access_token" ]}

json.getString("status");

or the array with

JSONArray jsonArray = new JSONArray(json.getString("object"));

or you use the method getJSONArray()

JSONArray jsonArray = json.getJSONArray("object");
