Why does my CSS and PHP include not load in my Web

问题:

I use a WebView in my app. When the app is not connected to the internet I want to serve the site locally. I was able to build the APK and install the app onto my device, but when I start the app offline, it is just showing the body PHP, but it did not call/load the CSS File or include the PHP files.

Directory structure in Android Studio :

This is my MainActivity:

public class Callback extends WebViewClient{
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl){
            Toast.makeText(getApplicationContext(), "No Internet Access!", Toast.LENGTH_SHORT).show();
            view.loadUrl("file:///android_asset/nointernet.php");
        }
    }

This is my "No Internet" page

<body>
    <!-- Navigation Bar -->
  <?php include 'assets\inc\navmobpage.php';  ?>
    <!-- Page Content -->
    <div class="container" align="center" style="background-color: white;padding-top: 50px;">
    <img src="assets\img\nointernet.png" width="100%" />
    <a class="btref" href="http://xx.xx.xx">REFRESH</a>
  </div>

  <?php include 'assets\inc\footmob.php';   ?>

    <!-- Bootstrap core JavaScript -->
    <script src="assets\general\jquery\jquery.min.js"></script>
    <script src="assets\general\bootstrap\js\bootstrap.bundle.min.js"></script>

  </body>

Android does not ship with a PHP server. Therefore for all common intents and purposes, it is not possible to serve a .php file locally.

You would need to rewrite your offline page to function without any PHP code.

I assume the CSS you refer to is also part of the PHP include and therefore is not loading for the same reason.
