HttpHostConnectException連接拒絕ConnectException ErrnoException

Question

我在我的應用程序中發生此異常的網絡進程，我不知道如何解決此問題。在其全球IP地址我使用從我們的服務器

<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> 
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
<uses-permission android:name="android.permission.RECORD_AUDIO" /> 
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> 

和URI已經是：我已經在我的清單應用某些權限，這裏是我申請我的整個應用程序的權限。它在瀏覽器中正常工作，但在應用程序中，此異常出現。這裏是堆棧跟蹤：

任何幫助將不勝感激。謝謝。

編輯： 好了，這裏是我的工具：

public static String getRequest(String path){ 
    String url = http://xxx.xx.xxx.xxx:8080/SampleApi/sample-apis; // Global URL of the API 
    String username = "sampleuname"; 
    String password = "samplepass"; 

    CredentialsProvider credProvider = new BasicCredentialsProvider(); 
    credProvider.setCredentials(new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT), 
      new UsernamePasswordCredentials(username, password)); 

    try{ 
     DefaultHttpClient httpClient = new DefaultHttpClient(); 
     httpClient.setCredentialsProvider(credProvider); 
     HttpGet httpGet = new HttpGet(url + path); 
     HttpResponse httpResponse = httpClient.execute(httpGet); // Okay, so the stack trace is pointing in this line 

     HttpEntity httpEntity = httpResponse.getEntity(); 
     if(httpEntity != null){ 
      inStream = httpEntity.getContent(); 
      String jsonString = convertStreamToString(inStream); 
      return jsonString; 
     } 
    } catch (UnsupportedEncodingException e) { 
     e.printStackTrace(); 
    } catch (ClientProtocolException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

    return "Request NULL"; 
} 

和我通話的AsyncTask：

public class LoginTask extends AsyncTask<String, Void, String> { 

    @Override 
    protected String doInBackground(String... path) { 
     Log.d(Constant.TAG_LOGIN, path[0]); 

     String apiRequestReturn = Utility.getRequest(path[0]); // So here's the other line pointed by the stack trace where I called Utility 
     if (apiRequestReturn.equals("")) { 
      Log.d(Constant.TAG_LOGIN, "WebService request is null"); 
      return null; 
     } else { 
      Log.d(Constant.TAG_LOGIN, "WebService request has data"); 
      return apiRequestReturn; 
     } 
    } 

    @Override 
    protected void onPostExecute(String result) { 
     super.onPostExecute(null); 

     //JSON PARSING 
    } 
} 

Answer 1

我LSO面對我的設備同樣的問題。具有json響應的URI在瀏覽器中正常工作，但在設備中引發異常。我只是重新啓動我的設備，然後它在移動端工作。您嘗試重新啓動您的設備。

Answer 2

請按照這些解決方案解決您的問題。

1>檢查你的清單文件的互聯網許可有沒有。

2>通過休息客戶端瀏覽器檢查您的URL並傳遞適當的請求。

3>打開手機中的網址如： - http://yourIP地址/端口這只是爲了檢查您是否有權限或不在移動中打開此網址。
