AndroidHttpClient.execute正在恢复HTT presponse为空 [英] AndroidHttpClient.execute is returning httpresponse as null

问题描述

我想从下面的code访问我的URI

 的AsyncTask AsyncTask的=新的AsyncTask（）{        @覆盖
        保护对象doInBackground（对象... PARAMS）{
            AndroidHttpClient的HttpClient = AndroidHttpClient.newInstance（）;
            HttpUriRequest uriGetRequest =新HTTPGET（HTTP：//本地主机：8080 / restsql-0.8.6 / RES /）;
            HTT presponse HTT presponse = NULL;
            尝试{
                HTT presponse = httpClient.execute（uriGetRequest）;
                ;
            }赶上（例外五）{
                // TODO自动生成catch块
                如果（E！= NULL）{
                Log.e（ModelLoader，e.getMessage（），E）;
                }
                Log.e（型号装载机，同时呼吁执行错误）;
            }
            返回HTT presponse;
        }
    };
    asyncTask.execute（新对象（））;
 

但总是HTT presponse为空。即使没有异常。
我也象 https://google.co.in/ 其做工精细有效的URI检查。
我也从URI的浏览器工作正常。
由于没有抛出的异常，我无法进一步进行。

解决方案

  

在AVD连接到本地主机，你需要使用网址

  http://10.0.2.2/
 

而不是

 的http：//本地主机/
 

有关参考。

I am trying to access my uri from the below code

    AsyncTask asyncTask = new AsyncTask() {

        @Override
        protected Object doInBackground(Object... params) {
            AndroidHttpClient httpClient = AndroidHttpClient.newInstance("");
            HttpUriRequest uriGetRequest = new HttpGet("http://localhost:8080/restsql-0.8.6/res/");
            HttpResponse httpResponse = null;
            try {
                httpResponse = httpClient.execute(uriGetRequest);
                ;
            } catch (Exception e) {
                // TODO Auto-generated catch block
                if(e!=null){
                Log.e("ModelLoader", e.getMessage(), e);
                }
                Log.e("Model Loader", "Error while calling execute");
            }
            return httpResponse;
        }
    };
    asyncTask.execute(new Object());

But always the httpresponse is null. Even no exception is thrown. I have checked with a valid uri like https://google.co.in/ and its working fine. Also my URI from browser is working fine . As there is no exception thrown I am not able to proceed further.

解决方案

In AVD to connect to localhost you need to use url

       http://10.0.2.2/

instead of

        http://localhost/
