Question

Change the "Web page unavailable" page when there is no internet connection

Good afternoon. I'm new to android. A question arose: There is actually webview that will open a certain site. If you turn off the Internet, the window "Web page unavailable" appears, etc.

Is it possible to change this particular page?

You can add a check for the presence of an Internet connection and, if there is no Internet connection, feed the necessary information to WebView. Eg:

if (isConnected()) {
    //Стандартная Ваша загрузка
} else {
    // Показываем текст:
    webView.loadData("Извините, интернета нет, вот мое сообщение/пожелание", "text/html", "utf-8");
    //Либо кормим подготовленную страницу:
    //webView.loadUrl("file:///android_asset/myPage.html");
}

You can catch the error by blocking the WebView onReceivedError, then replace html-ky or close webview

 webView.setWebViewClient(new WebViewClient() {
    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            super.onReceivedError(view, errorCode, description, failingUrl);
            //logic
    }
 });
