[Android] 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
  checkVerify();
 
}

            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.INTERNET, Manifest.permission.CAMERA,

                    Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CALL_PHONE}, 1);
        }
    }
}
 
private class WebViewClientClass extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
        //Log.d("WebViewClient URL : " , request.getUrl().toString());
 
        String url = request.getUrl().toString();
        if (url.startsWith("tel:")) {

                    startActivity(marketIntent);
                }
 
                return true;
            } catch (Exception e) {
                Log.d("shouldOverrideUrlLoading()","intent part Error");
                e.printStackTrace();
            }
 
 
        } else {
 
            view.loadUrl(request.getUrl().toString());
        }

        //return super.shouldOverrideUrlLoading(view, request);
    }
}

 

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

각각 Intent를 띄우는 형태로 처리되어 있다.
