You need to override the onReceivedSslError() method of the WebViewClient for the webpage to display. Here is what your code should look like :

private WebView WebDimrah;
private WebSettings WebSettingDimrah;

@SuppressLint("SetJavaScriptEnabled")
@RequiresApi(api = Build.VERSION_CODES.KITKAT)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);


WebDimrah  = (WebView)findViewById(R.id.WebView1);
WebSettingDimrah  = WebDimrah.getSettings() ;
WebDimrah.getSettings().setJavaScriptEnabled(true);

WebDimrah.setWebViewClient(new WebViewClient() {
@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {

handler.proceed();

      }
   });
 WebDimrah.loadUrl("https://facebook.com");

}

Also, in your Android.xml file (manifest) add this line: android:usesCleartextTraffic="true" inside the ... tag.

sorry but now i had a blank page – Dimas Rahmadian Nov 17 '19 at 11:45
@DimasRahmadian i'll add some code to the one above. Try it again. – Mayokun Nov 17 '19 at 11:46
@DimasRahmadian try the above code. Also I believe you have added the necessary permissions to your manifest file i.e `` – Mayokun Nov 17 '19 at 11:55
I have added it, but it's still blank – Dimas Rahmadian Nov 17 '19 at 11:59
@DimasRahmadian can you show a copy of your Logcat ? – Mayokun Nov 17 '19 at 11:59
@DimasRahmadian i just figured out the issue. The webpage would display on android versions lower than API 29. It displays on API 28 and lower. – Mayokun Nov 17 '19 at 12:32
Honestly it's my new experience, and now what should i do sir? – Dimas Rahmadian Nov 17 '19 at 12:38
@DimasRahmadian, if what Mayokun said is true, then you might want to check here https://stackoverflow.com/questions/52594637/webview-is-not-loading-page-in-android-9-0 – Wale Nov 17 '19 at 13:09
@DimasRahmadian the newly edited code would work on Android 9 (API Level 28) and below. The issue is for Android Q (API Level 29) which I have opened an issue for :https://stackoverflow.com/questions/58901080/android-q-api-level-29-doesnt-load-https-websites-gives-error-neterr-acc – Mayokun Nov 17 '19 at 13:48
@DimasRahmadian add this `android:usesCleartextTraffic="true"` to your `Android.xml` file inside the .... tag. The code above works fine now. – Mayokun Nov 17 '19 at 14:02
@Mayokun thankyou sir, my problem has been solved, you're a good person. thank you and sorry for my bad english. – Dimas Rahmadian Nov 18 '19 at 04:20
@Whales thanks for your help too, and sorry for my bad english – Dimas Rahmadian Nov 18 '19 at 04:20
