웹뷰로 sd_test.php파일을 불러온후 페이지내 스캐너버튼클릭->openScan()함수가 호출되어
안드로이드에서 스캐너구동->스캔값을 가져와서 다시 sd_test.php파일에 함수를통해 보내려고 합니다.
현재 onActivityResult 에서 sData값까지 가져오는건 확인했습니다. 그다음
webView.loadUrl("javascript:"+strJavaScript);이렇게 호출하면 안되는데...제가 잘못구현을 한건가봅니다..
아직 안드로이드한지가 얼마안되서...모르는게 많구요..ㅠ
비동기식 네이티브방식이 따로있는지.. 방법을 계속 구글링하는데 갈피를 못잡습니다. 조언좀 주세요
