i have some trouble when i used this code in android 4.0 i did not get Response but i got Response in 2.2,2.3,2.3.3 version
List<NameValuePair> pwadd = new ArrayList<NameValuePair>();
pwadd.add(new BasicNameValuePair("UName", UName));
HttpParams httpParameters = new BasicHttpParams();
HttpClient httpclient = new DefaultHttpClient(httpParameters);
HttpPost httppost = new HttpPost(
"http://10.0.2.2/new/webser/Load.php");
httppost.setEntity(new UrlEncodedFormEntity(pwadd));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
BufferedReader reader = new BufferedReader(
new InputStreamReader(is, "iso-8859-1"), 8);
sb = new StringBuilder();
sb.append(reader.readLine() + "\n");
String line = "0";
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
String response = sb.toString();
what should i do in this code to run in android 4.0 version?
try these in an async task. you need to make network stuff in a separate thread anyway
public static String PrepareSendPostData_DetailsActivity(String station_id) {
//Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("your url here");
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(100);
nameValuePairs.add(new BasicNameValuePair("param_1", "value_1"));
nameValuePairs.add(new BasicNameValuePair("param_2", "ok"));
nameValuePairs.add(new BasicNameValuePair("module", "dbgestion"));
nameValuePairs.add(new BasicNameValuePair("pdv_id", station_id));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
String responseBody = getResponseBody(response);
if (responseBody != null)
return responseBody;
else
return null;
} catch (ClientProtocolException e) {
Log.e("exception here", e.getMessage().toString());
return null;

response_text = _getResponseBody(entity);
} catch (ParseException e) {
e.printStackTrace();
} catch (IOException e) {
if (entity != null) {
try {
entity.consumeContent();
} catch (IOException e1) {
}
}
}
return response_text;
}
public static String _getResponseBody(final HttpEntity entity) throws IOException, ParseException {
if (entity == null) {
throw new IllegalArgumentException("HTTP entity may not be null");
}
InputStream instream = entity.getContent();
if (instream == null) {
return "";
}
if (entity.getContentLength() > Integer.MAX_VALUE) {
throw new IllegalArgumentException(
"HTTP entity too large to be buffered in memory");
}
String charset = getContentCharSet(entity);
if (charset == null) {
charset = HTTP.DEFAULT_CONTENT_CHARSET;
}
Reader reader = new InputStreamReader(instream, charset);
StringBuilder buffer = new StringBuilder();
try {
char[] tmp = new char[1024];
int l;
while ((l = reader.read(tmp)) != -1) {
buffer.append(tmp, 0, l);
}
} finally {
reader.close();
}
return buffer.toString();
}
public static String getContentCharSet(final HttpEntity entity) throws ParseException {
if (entity == null) {
throw new IllegalArgumentException("HTTP entity may not be null");
}
String charset = null;
if (entity.getContentType() != null) {
HeaderElement values[] = entity.getContentType().getElements();
if (values.length > 0) {
NameValuePair param = values[0].getParameterByName("charset");
if (param != null) {

return charset;

On some devices it's working normally like on Galaxy S6 running Android 6.0.1, but on most other devices I get error.
Why some devices have problems with it and others don't?
I got this code, any suggestions why it's not returning any value to the "toBeSplit" String?
I call the method this way.
new Thread(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
getData();
}
}).start();
Here is the actual method, i have tried 1000 ways and it just aint working..
private void getData() {
StringBuilder builder = new StringBuilder();
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, timeout);
HttpConnectionParams.setSoTimeout(httpParams, timeout);
HttpClient client = new DefaultHttpClient(httpParams);
String yourUrl = "http://www.ratemyplays.com/form.php";
HttpGet httpGet = new HttpGet(yourUrl);
{
try {
HttpResponse response = client.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(content));
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
}
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
}
}
toBeSplit = builder.toString();
split2 = toBeSplit.split(",");
}
Use Code:
StringBuilder builder = new StringBuilder();
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, timeout);
HttpConnectionParams.setSoTimeout(httpParams, timeout);
HttpClient client = new DefaultHttpClient(httpParams);
String yourUrl = "http://www.ratemyplays.com/form.php";
HttpGet httpGet = new HttpGet(yourUrl);
{
try {
HttpResponse response = client.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(content));
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
}
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
}
}
String tempstr = builder.toString();
String str[] = tempstr.split(",");
Try to split as below:
try {
response = client.execute(request);
if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
InputStream in = response.getEntity().getContent();
StringBuilder sb = new StringBuilder();
String line = "";
BufferedReader bf = new BufferedReader(
new InputStreamReader(in));
while ((line = bf.readLine()) != null) {
sb.append(line);
}
m_response = sb.toString();
StringBuilder split = new StringBuilder();
split =m_response.split(",");
}
} catch (ClientProtocolException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();

client.Execute(RequestMethod.GET);
String response=client.getResponse();

Q: how to add json data to this request?
A: Set your content type, length and write the payload.
Here's an example:
http://localtone.blogspot.com/2009/07/post-json-using-android-and-httpclient.html
JSONObject holder = new JSONObject();
...
JSONObject data = new JSONObject();
...
// Some example name=value pairs
while(iter.hasNext()) {
Map.Entry pairs = (Map.Entry)iter.next();
String key = (String)pairs.getKey();
Map m = (Map)pairs.getValue();
JSONObject data = new JSONObject();
Iterator iter2 = m.entrySet().iterator();
while(iter2.hasNext()) {
Map.Entry pairs2 = (Map.Entry)iter2.next();
data.put((String)pairs2.getKey(), (String)pairs2.getValue());
}
holder.put(key, data);
}
...
StringEntity se = new StringEntity(holder.toString());
...
httpost.setHeader("Accept", "application/json");
httpost.setHeader("Content-type", "application/json");
...
I am creating an HttpPost object in Android to communicate with a server operated by a client. Unfortunately the server isn't providing either of us with very useful error messages; I would like to see the content of the HttpPost object as a string so I can send it to our client and he can compare it with what he's expecting.
How can I convert an HttpPost object into a string that reflects how it would look as it arrived at the server?
Should use it after execute
public static String httpPostToString(HttpPost httppost) {
StringBuilder sb = new StringBuilder();
sb.append("\nRequestLine:");
sb.append(httppost.getRequestLine().toString());
int i = 0;
for(Header header : httppost.getAllHeaders()){
if(i == 0){
sb.append("\nHeader:");
}
i++;
for(HeaderElement element : header.getElements()){
for(NameValuePair nvp :element.getParameters()){
sb.append(nvp.getName());
sb.append("=");
sb.append(nvp.getValue());
sb.append(";");
}
}
}
HttpEntity entity = httppost.getEntity();
String content = "";
if(entity != null){
try {
content = IOUtils.toString(entity.getContent());
} catch (Exception e) {
e.printStackTrace();
}
}
sb.append("\nContent:");
sb.append(content);
return sb.toString();
}

I usually do post in this way (The server answer is a JSON object) :
try {
postJSON.put("param1", param1);
postJSON.put("param2",param2);
} catch (JSONException e) {
e.printStackTrace();
}
String result = JSONGetHTTP.postData(url);
if (result != null) {
try {
JSONObject jObjec = new JSONObject(result);
}
} catch (JSONException e) {
Log.e(TAG, "Error setting data " + e.toString());
}
}
And postData is:
public static String postData(String url, JSONObject obj) {
// Create a new HttpClient and Post Header
HttpClient httpclient = null;
try {
HttpParams myParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(myParams, 30000);
HttpConnectionParams.setSoTimeout(myParams, 30000);
httpclient = new DefaultHttpClient(myParams);
} catch (Exception e) {
Log.e("POST_DATA", "error in httpConnection");
e.printStackTrace();
}
InputStream is = null;
try {
HttpPost httppost = new HttpPost(url.toString());
//Header here httppost.setHeader();
StringEntity se = new StringEntity(obj.toString());
httppost.setEntity(se);
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
// // Do something with response...
is = entity.getContent();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
// convert response to string
BufferedReader reader = null;
String result = null;
try {
reader = new BufferedReader(new InputStreamReader(is, "UTF-8"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
result = sb.toString();
} catch (Exception e) {
Log.e("log_tag", "Error converting result " + e.toString());
} finally {
try {
if (reader != null)
reader.close();
if (is != null)
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if (result != null) {
try {
#SuppressWarnings("unused")
JSONObject jObjec = new JSONObject(result);
} catch (JSONException e) {
Log.e("log_tag", "Error parsing data " + e.toString());
}
}
return result;
}
Hope it helps
Well i actually did HTTP-Post using NameValuePair...... I am showing the code which i use to do an HTTP-Post and then converting the Response into a String
See the below Method code:
public String postData(String url, String xmlQuery) {
final String urlStr = url;
final String xmlStr = xmlQuery;
final StringBuilder sb = new StringBuilder();
Thread t1 = new Thread(new Runnable() {
public void run() {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(urlStr);
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("xml", xmlStr));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
Log.d("Vivek", response.toString());
HttpEntity entity = response.getEntity();
InputStream i = entity.getContent();
Log.d("Vivek", i.toString());
InputStreamReader isr = new InputStreamReader(i);
BufferedReader br = new BufferedReader(isr);
String s = null;
while ((s = br.readLine()) != null) {
Log.d("YumZing", s);
sb.append(s);
}
Log.d("Check Now",sb+"");
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
t1.start();
try {
t1.join();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("Getting from Post Data Method "+sb.toString());
return sb.toString();
}
I'm sorry for a little duplication, here, here, but they say, that if you read the the last byte of the body of response and close the input stream. It is ready for another request. But look what I got here, and I always get this error when executing a new request.
Invalid use of SingleClientConnManager: connection still allocated
public String detectGooglePost(String text) throws SystemException {

HttpPost httpPost = new HttpPost(createURI(qParams));
httpPost.addHeader("X-HTTP-Method-Override", "GET");
try {

} catch (UnsupportedEncodingException e) {
throw new SystemException("Problem when buidling Google request entity", e);

try {

}
int sc = response.getStatusLine().getStatusCode();
if (sc != HttpStatus.SC_OK)
throw new SystemException("google status code : " + sc);
StringBuilder builder = getBuilder(response);
String language = processJson(builder.toString());
return language;
}
private StringBuilder getBuilder(HttpResponse response) throws SystemException {
HttpEntity entity = response.getEntity();
if (entity == null)
throw new SystemException("response entity null");
StringBuilder builder = new StringBuilder();
BufferedReader in = null;
String str;
try {
in = new BufferedReader(new InputStreamReader(entity.getContent()));
while ((str = in.readLine()) != null)
builder.append(str);
} catch (IOException e) {
throw new SystemException("Reading input stream of http google response entity problem", e);
} finally {
IOUtils.closeQuietly(in);
}
if (builder.length() == 0)
throw new SystemException("content stream of response entity empty has zero length");
return builder;
}
How should I release the connection ? The stream is read and closed. But still when detectGooglePost(text) method is called again (singleton HttpClient instance), it throws that error.
Man it must work, try this :
HttpResponse response;
String responseBody;
try {
response = httpclient.execute(request);
int sc = response.getStatusLine().getStatusCode();
if (sc != HttpStatus.SC_OK)
throw new SystemException("google status code : " + sc);
HttpEntity entity = response.getEntity();
if (entity == null)
throw new SystemException("response entity null");
responseBody = EntityUtils.toString(entity);
} catch (Exception e) {
request.abort();
throw new SystemException("Problem when executing Google request", e);
}
