Android WebView Not Displaying Certain Websites-CodePudding

Trying to create an Android app for my site which can simply display the webpage in the Android app.

I have the following code in MainActivity.java

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        WebView mywebview = (WebView) findViewById(R.id.webView);
        /*WebSettings webSettings = mywebview.getSettings();
        webSettings.setJavaScriptEnabled(true); Works with and without this commented part*/
        mywebview.loadUrl("https://www.javatpoint.com/");

    }
}

The above is working fine and displays the 'https://www.javatpoint.com/' webpage correctly in the Android app.

However, the moment I change the "mywebview.loadUrl("https://www.javatpoint.com/");" to my own test website "mywebview.loadUrl("https://pricepurple.com/j4f/xaph1.html");" , it displays a blank screen on the emulator as well as the connected mobile app.

I have granted all the necessary permissions in the manifest.xml file, like,

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

And since it is working for 'https://www.javatpoint.com/' but not for my site 'https://pricepurple.com/j4f/xaph1.html', I assume there is some configuration issue??

Any help will be appreciated.

PS: Mentioned a test page on my test site, so that problem can be analyzed properly. Once the root cause and fix is known, I'' edit the q to update it to example.com with specific details

Make this link from https://pricepurple.com/j4f/xaph1.html to https://www.pricepurple.com/j4f/xaph1.html. You may be missing a www.

You need to use setWebChromeClient to enable javascript in your WebView. But don't worry, you can use both setWebChromeClient and setWebViewClient in the same time. Just like in official docs:

  // Let's display the progress in the activity title bar, like the
  // browser app does.
  getWindow().requestFeature(Window.FEATURE_PROGRESS);

  webview.getSettings().setJavaScriptEnabled(true);

  final Activity activity = this;
  webview.setWebChromeClient(new WebChromeClient() {
    public void onProgressChanged(WebView view, int progress) {
      // Activities and WebViews measure progress with different      scales.
      // The progress meter will automatically disappear when we reach 100%
      activity.setProgress(progress * 1000);
    }
  });
  webview.setWebViewClient(new WebViewClient() {
    public void onReceivedError(WebView view, int errorCode, String      description, String failingUrl) {
      Toast.makeText(activity, "Oh no! "   description,      Toast.LENGTH_SHORT).show();
    }
  });

  webview.loadUrl("https://pricepurple.com/j4f/xaph1.html");

Try this. uncomment those websetting lines and after this line setJavaScriptEnabled(true) write setDomStorageEnabled(true)

like this webSettings.setDomStorageEnabled(true)
