AsyncHttpClient fetchSecond=new AsyncHttpClient();
		fetchSecond.put("http://pharmamax.solutionsmax.com/PackageMax.svc/FetchSecondaryNumber", params,new AsyncHttpResponseHandler()
		{
			@Override
			public void onSuccess(String response)
			{
				Toast.makeText(getApplicationContext(), response, Toast.LENGTH_SHORT).show();
			try{
				JSONObject obj3 = new JSONObject(response);
				JSONArray jsonArray3 = obj3.getJSONArray("FetchSecondaryNumberResult");
			    int length = jsonArray3.length();
			    if(length!=0)
			    {
			    	for(int i=0;i<length;i++)
			    	{
			    		JSONObject user = jsonArray3.getJSONObject(i);
			    		 //result=user3.getString("Res").toString();
			    		 number.setText(user.get("Res").toString());
			    	}
			     }
			     else
			     {
			    	 Toast.makeText(getApplicationContext(), "no data", Toast.LENGTH_LONG).show();
			     }
			}catch(JSONException e){
				Toast.makeText(getApplicationContext(), "Exception", Toast.LENGTH_LONG).show();
				//e.printStackTrace();
			}
			
			}
			@Override
			public void onFailure(int statusCode, Throwable error,String content){
				//Toast.makeText(getApplicationContext(), content, Toast.LENGTH_LONG).show();
				 if(statusCode == 404){
                  Toast.makeText(getApplicationContext(), "Requested resource not found", Toast.LENGTH_LONG).show();
              } 
				 else if(statusCode == 500){
                  Toast.makeText(getApplicationContext(), "Something went wrong at server end", Toast.LENGTH_LONG).show();
              }
				 else{
					 Toast.makeText(getApplicationContext(), "1", Toast.LENGTH_LONG).show();
                  Toast.makeText(getApplicationContext(), "Unexpected Error occcured! [Most common Error: Device might not be connected to Internet or remote server is not up and running]", Toast.LENGTH_LONG).show();
              }
