继续解析数据的错误org.json.JsonException:Value <!DOCTYPE

I have looked at several answered posted here and on Google and am still confused why I am getting this error. The json variable I created reads out I do not have permission. I changed the permissions to allow all and this did not solve the error. I also played around with my URL using my computers IP address of 196.... and the online examples of When I use my IP I get the above error. When I used the 127.0 I get failed to connect error, which I assume is because the IP address does not go anywhere. I tested my PHP code and it input data into MySQL db. So I know that my problem is in my java code. I am posting my code below and trying to post minimal code so I do code dump. If you want me to post more code let me know.

        try {

        // check for request method
            // request method is POST
            // defaultHttpClient
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);
            httpPost.setEntity(new UrlEncodedFormEntity(params));

            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity = httpResponse.getEntity();
            is = httpEntity.getContent();

        }else if(method.equals("GET")){
            // request method is GET
            DefaultHttpClient httpClient = new DefaultHttpClient();
            String paramString = URLEncodedUtils.format(params, "utf-8");
            url += "?" + paramString;
            HttpGet httpGet = new HttpGet(url);

            HttpResponse httpResponse = httpClient.execute(httpGet);
            HttpEntity httpEntity = httpResponse.getEntity();
            is = httpEntity.getContent();

    } catch (UnsupportedEncodingException e) {
    } catch (ClientProtocolException e) {
    } catch (IOException e) {

    try {
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                is, "iso-8859-1"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "
        json = sb.toString();
    } 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 (JSONException e) {
        Log.e("JSON Parser", "Error parsing data " + e.toString());

    // return JSON String
    return jObj;

So what do I need to do to get permission?
The Error message I am getting for

catch (Exception e) {
        Log.e("Buffer Error", "Error converting result " + e.toString());


Error parsing data org.json.JSONException: Value DOCTYPE of type java.lang.String cannot be converted to JSONObject

    已采纳 will be your local android device where it's not likely you have a web server running. The permission you need in your manifest is INTERNET, make sure you have it and then update your question to post the exact error and error codes you get if you are still experiencing issues
