JSONException: Value of type java.lang.String cannot be converted to JSONObject

Question

I have a JSON file with 2 JSON-Arrays in it: One Array for routes and one Array for sights.

A route should consist of several sights where the user gets navigated to

Answer 1

Here is UTF-8 version, with several exception handling:

static InputStream is = null;
static JSONObject jObj = null;
static String json = null;
static HttpResponse httpResponse = null;

public JSONObject getJSONFromUrl(String url) {
    // Making HTTP request
    try {
        HttpParams params = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(params, 10000);
        HttpConnectionParams.setSoTimeout(params, 10000);
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
        HttpProtocolParams.setUseExpectContinue(params, true);
        // defaultHttpClient
        DefaultHttpClient httpClient = new DefaultHttpClient(params);
        HttpGet httpPost = new HttpGet( url);
        httpResponse = httpClient.execute( httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        is = httpEntity.getContent();           
    } catch (UnsupportedEncodingException ee) {
        Log.i("UnsupportedEncodingException...", is.toString());
    } catch (ClientProtocolException e) {
        Log.i("ClientProtocolException...", is.toString());
    } catch (IOException e) {
        Log.i("IOException...", is.toString());
    }

    try {
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                is, "utf-8"), 8); //old charset iso-8859-1
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        is.close();
        reader.close();
        json = sb.toString();
        Log.i("StringBuilder...", json);
    } catch (Exception e) {
        Log.e("Buffer Error", "Error converting result " + e.toString());
    }
    // try parse the string to a JSON object
    try {
        jObj = new JSONObject(json);
    } catch (Exception e) {
        Log.e("JSON Parser", "Error parsing data " + e.toString());
        try {
            jObj = new JSONObject(json.substring(json.indexOf("{"), json.lastIndexOf("}") + 1));
        } catch (Exception e0) {
            Log.e("JSON Parser0", "Error parsing data [" + e0.getMessage()+"] "+json);
            Log.e("JSON Parser0", "Error parsing data " + e0.toString());
            try {
                jObj = new JSONObject(json.substring(1));
            } catch (Exception e1) {
                Log.e("JSON Parser1", "Error parsing data [" + e1.getMessage()+"] "+json);
                Log.e("JSON Parser1", "Error parsing data " + e1.toString());
                try {
                    jObj = new JSONObject(json.substring(2));
                } catch (Exception e2) {
                    Log.e("JSON Parser2", "Error parsing data [" + e2.getMessage()+"] "+json);
                    Log.e("JSON Parser2", "Error parsing data " + e2.toString());
                    try {
                        jObj = new JSONObject(json.substring(3));
                    } catch (Exception e3) {
                        Log.e("JSON Parser3", "Error parsing data [" + e3.getMessage()+"] "+json);
                        Log.e("JSON Parser3", "Error parsing data " + e3.toString());
                    }
                }
            }
        }
    }

    // return JSON String
    return jObj;

}
