WebView 작업할때 Net::ERR_UNKNOWN_URL_SCHEME 에러 발생할때 (전화걸기,문자보내기 안된다)

하이브리드앱을 만들때 WebView 상에서 작업을 할때,

Net::ERR_UNKNOWN_URL_SCHEME

라는 메세지가 뜨고 전화걸기, 문자보내기 인텐트가 연동이 안될때, 아래의 소스를 참고하고 해결토록 하자.

private WebView webView1;
protected void onCreate(Bundle savedInstanceState) {
 
  webView1 = (WebView) findViewById(R.id.webView1);
  webView1.setWebViewClient(new WebViewClientClass());
 
  // 각종 권한 획득

WebViewClient 를 상속한 WebViewClientClass 에서 url 이 tel: , sms: , intent: 등의 주소로 들어올때 각각 if문안에

각각 Intent를 띄우는 형태로 처리되어 있다.
