Send data from android to web api service

Question

I have a problem in my android Background service. While send the data using http protocol it shows ClientProtocolException

My WebAPI is

 [AcceptVerbs("GET", "POST")]
 [ActionName("InsertLocationDetails")]
 public string InsertLocationDetails([FromBody]LocationDetails locDetails )
 {
 return objLocationService.InsertLocationDetails(locDetails.UserId,locDetails.DateTime.ToString(),
 locDetails.Latitude,locDetails.Longitude,locDetails.Status.ToString(),locDetails.Location.ToString());
 }

I have my LocationDetails class with paramaters

 public class LocationDetails
 {
 public int UserId { get; set; }
 public Double Latitude { get; set; }
 public Double Longitude { get; set; }
 public string Status { get; set; }
 public string DateTime { get; set; }
 public string Location { get; set; }
 }

In my Android background code i m using http protocol. I need to communicate with my web api service to insert the datas

 public String insertLocationDetails(int userid,String newtime,String status,double latitude,double longitude,String address,String city,String country) 
{ 
 HostUrl="http://URL/ServiceName/InsertLocationDetails"; 
 HttpClient httpClient = new DefaultHttpClient();
 HttpPost httpPost = new HttpPost(HostUrl);
 try
 { 
 List<NameValuePair> params = new LinkedList<NameValuePair>();
 params.add(new BasicNameValuePair("UserId",String.valueOf(userid)));
 params.add(new BasicNameValuePair("DateTime", newtime));
 params.add(new BasicNameValuePair("Latitude",String.valueOf(latitude)));
 params.add(new BasicNameValuePair("Longitude",String.valueOf(longitude)));
 params.add(new BasicNameValuePair("Status",status));
 params.add(new BasicNameValuePair("Location",(address+","+city+","+country)));
 httpPost.setHeader("Content-Type", "application/json");
 httpPost.setHeader("Accept", "application/json");
 HttpEntity entity = new UrlEncodedFormEntity(params, "UTF-8");
 httpPost.setEntity(entity);
 ResponseHandler<String> handler = new BasicResponseHandler();
 result =httpClient.execute(httpPost,handler);
 }
 catch (ClientProtocolException e)
 { 
 e.printStackTrace();
 Log.e(TAG, "ClientProtocolException in callWebService(). " + e.getMessage());
 }
 catch (IOException e)
 { 
 e.printStackTrace();
 Log.e(TAG, "IOException in callWebService(). " + e.getMessage());
 }
 return result;
 }}

Actually my jquery code is working properly and inserting values

My Javascript code is working properly

function insertLocationDetails()
{
 var url=serverUrl();
 var urlpath={
 UserId : userid,
 DateTime : datetime, 
 Latitude: latitude,
 Longitude : longitude, 
 Status: status,
 Location : address };
 $.ajax
 ({
 cache: false,
 async: true,
 type: "POST",
 dataType: "json",
 contentType: "application/json;charset=utf-8",
 url: url +"InsertLocationDetails",
 data: JSON.stringify(urlpath),
 success: function (result) 
 {
 var result = eval(result);
 for (var property in result) 
 {
 }
 }
 });
}

Kindly help me figure out the Exception in my Android Background service please give a correct code to make communication with my service

• NewDroidDev: hei @Arun how did you fix your problem here I tried your code and I get the same error the ClientProtocolException became null what is wrong can you please help me how would your fix it thanks

Answer 1

You are sending the request body as application/x-www-form-urlencoded but setting content type as JSON.

Instead of using;

`httpPost.setHeader("Content-Type", "application/json");`

use;

`httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");`
