How do contents in name value pair pass as arguments in Android Studio?

Suppose i have this
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("pin", "date"));
And When i use the following code
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://X.X.X.X/abcdef.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
what will be the post request? How will the arguments pass in the url?

found the answer
can refer this link for more details
arguments are passed as this
http://localhost/xyz.php?pin=date&package=123&requirements=xxx&last_date=25%20april

How to make Post Request using Smali code?

List<NameValuePair> params = new ArrayList<NameValuePair>(1);
params.add(new BasicNameValuePair("param-1", "12345"));
httppost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));
HttpResponse response = httpclient.execute(httppost);

Remove or replace special character in namevaluepair for http post request android

I have a problem when I tried to post my data it logged as :
[ObserverTRID=5QEET3TE10,
ObsType=Evaluate,
ObsDate=17-Jul-2014,
ObsTime=09:22:12,
// == loc
ObsTitle=bolllloooo,
//==obstset
MediaData={"MediaData":[{"RunNo":0,"Filename":"http://url/5QEET3TE10_3_5_20140717092206.jpg","MediaNo":4"Desc":01 Image_17-Jul-14No Marker.jpg}]},
PVPMediaCount=1,
SourceDevice=motorola XT1032 Android v19 App v2.0001,
ObsDept,
ObsSite,
TargetTRID=5QEET3TE10]
But I need to append every namevalue with "&" instead of "," This is my httppost request.
httppost.setEntity(new UrlEncodedFormEntity(mNameValuePairs));
This is my request i am posting the URL with the parameter nameevaluepair
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(mUrl);
if(mNameValuePairs==null){
mNameValuePairs = new ArrayList<NameValuePair>(1);
mNameValuePairs.add(new BasicNameValuePair("PostEvent", "Null"));
}
Log.e("namevalue ", mNameValuePairs.toString());
There I am settig entity by URLEncoding
httppost.setEntity(new UrlEncodedFormEntity(mNameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
String result = EntityUtils.toString(response.getEntity(),HTTP.UTF_8);
HttpEntity httpEntity = response.getEntity();

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
use this code in for parsing class

HttpPost response doesn't return the json object

I'm currently working on a project which needs to send a post request and get a json object from the server. Earlier I used Get method to access the json object. It worked fine. But because of some server changes I had to move to post method. Then it doesn't return me the json object that I got earlier from the 'get' method. I tried my best to come up with a solution but couldn't. Highly appreciate if anyone can help me to get through this problem.
private AdSniperAdObjectResponse postData(String url) {
//Bundle b = new Bundle();
HttpClient httpClient = HttpClientFactory.getThreadSafeClient();
//Log.d(TAG, "url: " + url);
try {
HttpPost httpPost = new HttpPost(url);
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Accept", "JSON");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(4);
nameValuePairs.add(new BasicNameValuePair("latitude", "-33.8736"));
nameValuePairs.add(new BasicNameValuePair("longitude", "151.207"));
nameValuePairs.add(new BasicNameValuePair("age", "35"));
nameValuePairs.add(new BasicNameValuePair("gender", "All"));
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity resEntity = httpResponse.getEntity();
if (resEntity != null) {
String resp = EntityUtils.toString(resEntity);
Above is the code that I use. Earlier I used HttpGet class. For HttpPost, the 'resp'variable is always null. Don't know what I did wrong.

should't this be like
HttpResponse httpResponse = httpClient.execute(httpPost);
if (httpResponse != null) {
String resp = httpResponse.toString();
and in case if server return JSONString..
say JSONObject data = new JSONObject(resp);
and then get values..

DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof (List<NameValuePair> ));
try with this and pass your data using this
jsonSerializer.WriteObject(reqStream, nameValuePairs );
reqStream.Close();
and again deserialize the response whatever you are getting

Before you attempt to get the HttpEntity, you should get the StatusLine and check that the status code is what you expect. I suspect that the real problem is that the server is sending an error response of some kind. And since you used an "Accept" header to request a JSON response, it is likely that the server is not sending any diagnostics in the response body ... so it is empty.

Guys I found the solution. It worked when I commented the following two lines.
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Accept", "JSON");
So thanks everyone for your answers. Highly appreciate.

Why my HttpPost can't receive all response data?

I'm on Android 1.5, and my code is like this:
HttpPost httpPost = new HttpPost(url);
HttpEntity entity = new UrlEncodedFormEntity(params, HTTP.UTF_8);
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost);
HttpEntity respEntity = response.getEntity();
String result = EntityUtils.toString(respEntity, DEFAULT_CHARSET);
After successfully executed these codes, the result is a stripped string. I've tried using browser to test the url+param, it works fine and got all data.
What's wrong with this code? Is there any parameters I need to specified?

Try using the ResponseHandler pattern instead and see if that gives you better results.

This works:
HttpResponse response=httpclient.execute(httppost);
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
