question: notify the host application that a key was not handled by the webview . except system keys , webview always consumes the keys in the normal flow or if shouldoverridekeyevent returns true . this is called asynchronously from where the key is dispatched . it gives the host application a chance to handle the unhandled key events . concode_field_sep int ERROR_FAILED_SSL_HANDSHAKE concode_elem_sep int ERROR_UNKNOWN concode_elem_sep int ERROR_FILE_NOT_FOUND concode_elem_sep int ERROR_UNSUPPORTED_AUTH_SCHEME concode_elem_sep int ERROR_BAD_URL concode_elem_sep int ERROR_PROXY_AUTHENTICATION concode_elem_sep int ERROR_TOO_MANY_REQUESTS concode_elem_sep int ERROR_HOST_LOOKUP concode_elem_sep int ERROR_AUTHENTICATION concode_elem_sep int ERROR_FILE concode_elem_sep int ERROR_REDIRECT_LOOP concode_elem_sep int ERROR_CONNECT concode_elem_sep int ERROR_UNSUPPORTED_SCHEME concode_elem_sep int ERROR_IO concode_elem_sep int ERROR_TIMEOUT concode_field_sep void onPageStarted concode_elem_sep void onLoadResource concode_elem_sep void onReceivedClientCertRequest concode_elem_sep void onReceivedLoginRequest concode_elem_sep void onPageFinished concode_elem_sep boolean shouldOverrideUrlLoading concode_elem_sep void onScaleChanged concode_elem_sep void onReceivedError concode_elem_sep void onReceivedSslError concode_elem_sep void onReceivedHttpAuthRequest concode_elem_sep void onFormResubmission concode_elem_sep boolean shouldOverrideKeyEvent concode_elem_sep void onTooManyRedirects concode_elem_sep void doUpdateVisitedHistory concode_elem_sep WebResourceResponse shouldInterceptRequest
