我正在尝试运行使用其他服务的Android应用程序，但我最终错误 [英] I Am Trying To Run An Android App That Uses Rest Service But I End Up In An Error

问题描述

以下代码用于获取下一个要输入的数据的数量。当我在浏览器中运行其余服务时，我得到结果{FetchSecondaryNumberResult：[{Res：2}]}。当我运行应用程序时，获取toast消息说发生意外错误！[最常见的错误：设备可能未连接到Internet或远程服务器未启动并运行]。我连接到网络，我使用async-http 1.4.4.jar这个程序。

请帮我解决这个问题。

the below code is used to get the number of datas to be entered next. when i run the rest service in browser i get result {"FetchSecondaryNumberResult":[{"Res":2}]}. when i run the app the get the toast message saying "Unexpected Error occcured!

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();

				//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();
              }
			 }

推荐答案

我发现了如何让它工作



错误是我用了fetchsecond.put（）;



必须用fetchsecond.get（）替换;

well i found out how to make it work

the mistake was i used fetchsecond.put();

this must be replaced by fetchsecond.get();
