안드로이드 앱 카카오톡 공유하기 (4011오류) - 해결

0. 요약

  안드로이드에서 onCreateWindow, onCloseWindow 설정을 안하면... 4011 오류가 발생할 수 있습니다.

  태블릿에서요. 

  스마트폰에서는 거의 안나타나는 듯.. 

 

 

I. 원인
 1. 클릭하면 : intent가 아니라 https://~~ 로 시작
 1-1. javascript 가 작동안한다고 생각 하였으나.. 아님.

 1-2. 4011 오류가 나타남. 

II. 발단 
 1. 카카오 안드로이드 하이브리드 구현시 추가할 사항 문서를 보게 됨  
   https://developers.kakao.com/docs/latest/ko/javascript/hybrid

 2. 아래 코드를   WebviewActivity.java,  private void loadWebView(String url) 에 추가하였더니..  로그를 찍음. 

            @Override
            public boolean onCreateWindow(WebView view, boolean isDialog, boolean isUserGesture, Message resultMsg) {
                log.d("webview", "WebViewActivity --- window.open 협의가 필요합니다.");

                return true;
            }
            @Override
            public void onCloseWindow(WebView window) {
                 log.d("webview", "WebViewActivity --- onCloseWindow");
    }

  3. 그래서 아래와 같이 적용 



III. WebviewActivity.java 에서(예임. 각각의 웹뷰)

 1. 멀티윈도우 추가
        mWebView.getSettings().setDomStorageEnabled(true);
        mWebView.getSettings().setSupportMultipleWindows(true);
