Android Post a JSON Object to the WEB SERVICE.


Android Post a JSON Object to the WEB SERVICE.

Impotent:
here developer better use the posting with in separate thread, if you want to use in main thread it's getting exception.

(any button click)button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) { 

final int TIMEOUT_MILLISEC = 10000;  // = 10 seconds
Thread t = new Thread(){
       public void run() {
        Looper.prepare(); 
    HttpParams httpParams = new BasicHttpParams();
    HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT_MILLISEC);
    HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
    HttpClient client = new DefaultHttpClient(httpParams);
    HttpPost request = new HttpPost("----- any post url here -----");
    //set post request type
    request.setHeader(HTTP.CONTENT_TYPE, "application/json; charset=utf-8");
    //request result type
    request.setHeader("Accept", "application/json; charset=utf-8");
JSONObject json = new JSONObject();
    try {
json.put("object_key1", "Value1").toString();// Example key, values 
json.put("object_key2", "Value2").toString();
json.put("object_key3", "Value3").toString();
JSONArray mainArr = new JSONArray();
   for(int i = 0; i < 3; i++){      
       JSONObject mainObj = new JSONObject();
       
   mainObj.put("key1", "any Value");
   mainObj.put("key2", "any Value");
       
   JSONArray innerArr = new JSONArray();
       
   for(int k = 0; k < 4 ; k++){        
       JSONObject innerObj = new JSONObject();
       innerObj.put("inner_key1", "any Value");
       
       innerArr.put(innerObj);
    }

  mainObj.put("innerArr", innerArr).toString();        
  mainArr(mainObj);
       }   
       
       json.put("inner_array", mainArr).toString();
Log.i("jason Object", json.toString());
StringEntity se = new StringEntity(json.toString());
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json"));
request.setEntity(se);      
HttpResponse response = client.execute(request); 
String temp = EntityUtils.toString(response.getEntity());
       Log.i("tag_responce", temp);
} catch (Exception e) {
e.printStackTrace();
}
Looper.loop(); //Loop in the message queue
           }
       };
       t.start();  
       
       }
   });
