Android에서 호스트 이름을 확인할 수 없습니다.

Question

서버에서 데이터를 가져 와서 표시 할 앱을 만들고 있습니다. 사용자에게 로그인을 요청하면 호스트 이름 (예 : stackoverflow.com)을 입력하면 프로그램이 중단되고 IP를 입력하면 제대로 작동하며 (예 : 198.252) 사이트에서 데이터를 가져올 수 있습니다. .206.16 (스택 오버플로의 IP 주소). 그래서이 문제가 아니다

내 AndroidManifest.xml에이

<uses-permission android:name="android.permission.INTERNET"/> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 

포함되어 있습니까 :

이

private String buildURL(Param... params) 
{ 
    String server = SessionInfo.getInstance().getServer(); 
    try{ 
     server = InetAddress.getByName(server).getHostAddress(); 
    } catch (UnknownHostException e1){ 
     Log.d("UNKNOWN HOST EXCEPTION", e1.toString()); 
     e1.printStackTrace(); 
    } 
    String sessionId = SessionInfo.getInstance().getSessionId(); 
    String url = "http://" + server + "/" + SITE_ADDRESS + "/api/login"; 
    return url; 
}

Answer 1

은 (후손 여기 설명을 다시 게시) 그것을 자신을 해결 좀 이상해. 입력 된 호스트 이름은 server/이며 충돌했습니다. 이 도메인은 브라우저에서 액세스 할 수 있습니다. 그러나 URL의 '전체'버전 인 server.companyname.com을 사용하여 문제가 해결되었습니다.
