[Android] conn.getResponseCode()에서 에러

안드로이드에서 웹을 접속해 띄워보려고 하는데,

잘 돌아가다가 conn.getResponseCode()에서 에러가 났다.

e.printStackTrace()를 catch부분에 두고 찍어보니

인터넷사용권한을 줘야 한다고 되어있어서

나름 그 권한 설정을 한다는게 application 태그 밑에 두었던 것이 문제였다.

(/AndroidManifest.xml 에서 users-permission)

위에처럼 uses-sdk 밑에 uses-permission을 주고 나서야 정상적으로 작동이 되었다.
