getContentResolver 오류 해결 방법

Question

?

private static class BrowserObserver extends ContentObserver {      private static String lastVisitedURL = "";      private static String lastVisitedWebsite = "";        //Query values:      final String[] projection = new String[] { Browser.BookmarkColumns.URL };  // URLs      final String selection = Browser.BookmarkColumns.BOOKMARK + " = 0";  // history item      final String sortOrder = Browser.BookmarkColumns.DATE;  // the date the item was last visited          public BrowserObserver(Handler handler) {          super(handler);      }          @Override      public void onChange(boolean selfChange) {          onChange(selfChange, null);      }          @Override   public void onChange(boolean selfChange, Uri uri) {          super.onChange(selfChange);            //Context m_context = Settinglock.class;    //Retrieve all the visited URLs:          //ContentResolver cor = mContext.getContentResolver();          Cursor cursor = mContext.getContentResolver().query(Browser.BOOKMARKS_URI, projection, selection, null, sortOrder);                 //Retrieve the last URL:          cursor.moveToLast();          final String url = cursor.getString(cursor.getColumnIndex(projection[0]));            //Close the cursor:          cursor.close();            if ( !url.equals(lastVisitedURL) ) {  // to avoid information retrieval and/or refreshing...              lastVisitedURL = url;                //Debug:              Log.d(url, "URL Visited: " + url + "\n");          }      }  }

인터넷에서 url이 변경되면 그것을 캐치하는 동작을 만들고 있는데요

위의 소스에서 getContentResolver부분에서 자꾸 에러가 납니다

왜 에러가 나는지 알 수 있을까요?

Answer 1

context.getApplicationContext() 으로 한번 바꿔서 해보세요
