Webview Android Studio только белый или черный дисплей ⇐ Android

[Anonymous]

why is there no display on my android webview, if I try other urls like www.youtube.com it works fine, the infoinfopedia url if searched through the browser there is a warning "Your connection is not private" but can still be seen if you press the advanced option, but in the webview there is only a black or white display. is there a way to fix it?

my code :

package com.example.myapplication import android.annotation.SuppressLint import android.content.Context import android.net.ConnectivityManager import android.net.http.SslError import android.os.Build import android.os.Bundle import android.view.KeyEvent import android.view.View import android.view.WindowInsets import android.view.WindowManager import android.webkit.SslErrorHandler import android.webkit.WebView import android.webkit.WebViewClient import android.widget.ProgressBar import android.widget.Toast import androidx.appcompat.app.AppCompatActivity class MainActivity : AppCompatActivity() { lateinit var loading: ProgressBar private lateinit var url: String private lateinit var webView: WebView override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) setFullscreen() init() setupUI() } private fun setFullscreen(){ //Menyembunyikan action bar supportActionBar?.hide() //Mengatur layout menjadi Full Screen if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) { window.insetsController?.hide(WindowInsets.Type.statusBars()) } else { window.setFlags( WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN ) } } private fun init(){ url = "https://infoinfopedia.kesug.com/login.php" loading = findViewById(R.id.pb_loading) webView = findViewById(R.id.wv_page) } private fun setupUI(){ if (isOnline(this)){ loadWebview() } else { Toast.makeText(this, "Tidak ada koneksi internet", Toast.LENGTH_SHORT).show() } } @SuppressLint("ServiceCast") fun isOnline(context: Context): Boolean { val connectivityManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager val networkInfo = connectivityManager.activeNetworkInfo return networkInfo != null && networkInfo.isConnectedOrConnecting } private fun loadWebview(){ webView.webViewClient = myWebclient() webView.settings.javaScriptEnabled = true webView.loadUrl(url) } inner class myWebclient: WebViewClient() { override fun onPageFinished(view:WebView, url:String) { super.onPageFinished(view, url) loading.visibility = View.GONE } override fun shouldOverrideUrlLoading(view:WebView, url: String):Boolean { view.loadUrl(url) return true } } override fun onKeyDown(keyCode:Int, event: KeyEvent):Boolean { if ((keyCode == KeyEvent.KEYCODE_BACK) && webView.canGoBack()) { webView.goBack() return true } return super.onKeyDown(keyCode, event) } fun onReceivedSslError(view: WebView?, handler: SslErrorHandler, error: SslError?) { handler.proceed() // Ignore SSL certificate errors } } i have tried to add
fun onReceivedSslError(view: WebView?, handler: SslErrorHandler, error: SslError?) { handler.proceed() // Ignore SSL certificate errors }
