Can't Upload Large String to Server

Question

I am trying to upload a string to server by post.. This is my code..

String URL = "http://myUrl/add?user_id="+user_id
        + "&text=" + text 
        + "&type=" + type;

URL = URL.replaceAll(" ", "%20");
URL = URL.replaceAll("\n", "%0A");
try {
    // defaultHttpClient
    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(URL);

    HttpResponse httpResponse = httpClient.execute(httpPost);
    HttpEntity httpEntity = httpResponse.getEntity();
    String result = EntityUtils.toString(httpEntity);

} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
} catch (ClientProtocolException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

This code is working when i am uploading a small string.. but when i am trying to send large string (more than 2 lines) for example.. it doesn't work.. Any suggestions?

Thank you :)

Method Get has Maximium Chars limit, instead Use Post

String URL = "http://myUrl/add";
try {
    // defaultHttpClient
    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(URL);
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("user_id", user_id));
    nameValuePairs.add(new BasicNameValuePair("text", text));
    nameValuePairs.add(new BasicNameValuePair("type", type));
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
    HttpResponse httpResponse = httpClient.execute(httpPost);
    HttpEntity httpEntity = httpResponse.getEntity();
    String result = EntityUtils.toString(httpEntity);

    } catch (UnsupportedEncodingException e) {
    e.printStackTrace();
    } catch (ClientProtocolException e) {
    e.printStackTrace();
    } catch (IOException e) {
    e.printStackTrace();
}

You should use \" to send a string:

String URL = "myUrl/add?user_id="+user_id 
+ "\"&text=\"" + text 
+ "\"&type=\"" + type;

Also you should use POST instead GET

You transfer your data as part of the query string, which is part of the URL. There is a maximum length on URLs which depends heavily on the client and server software. As far as I know there is no standard which defines this maximum.

Anyways, you should transfer a large amount of data in the HTTP request body. See here for an example.

Use NameValuePair for sending the data, you are using HTTP POST to send the data in GET Style. I will strongly recommend use of NameValuePair to send the data.A small example is List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("email","email")); DefaultHttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(url); httpPost.setEntity(new UrlEncodedFormEntity(params)); HttpResponse httpResponse = httpClient.execute(httpPost); HttpEntity httpEntity = httpResponse.getEntity();
