Answer 1

Try this

webview.webViewClient = AppWebViewClient()

Client

  class AppWebViewClient() : WebViewClient() {

        override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {

            view.loadUrl(url)
            return true
        }


    override fun onReceivedSslError(view: WebView, handler: SslErrorHandler, error: SslError) {
        var message = "SSL Certificate error."
        when (error.primaryError) {
            SslError.SSL_UNTRUSTED ->
            message = "The certificate authority is not trusted."
            SslError.SSL_EXPIRED ->
            message = "The certificate has expired.";
            SslError.SSL_IDMISMATCH ->
            message = "The certificate Hostname mismatch.";
            SslError.SSL_NOTYETVALID ->
            message = "The certificate is not yet valid.";
        }
        message += "\"SSL Certificate Error\" Do you want to continue anyway?";
        //Log your message
        handler.proceed()

    }
    }

Answer 3

Check if you have declared network permission in AndroidManifest.xml

Answer 4

Use this.

        startWebView("your url");

//Method
      private void startWebView(String url) {



    webView.setWebViewClient(new WebViewClient() {

        //If you will not use this method url links are opeen in new brower not in webview
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }

        //Show loader on url load
        public void onLoadResource (final WebView view, String url) {

        }
        public void onPageFinished(WebView view, String url) {

        }

    });
    webView.getSettings().setJavaScriptEnabled(true);
    webView.loadUrl(url);
}

Answer 5

I am using this code and also your link work perfectly for me just check this code:

final WebView webView=findViewById(R.id.webv);
    webView.getSettings().setLoadWithOverviewMode(true);
    webView.getSettings().setUseWideViewPort(true);
    webView.loadUrl("https://sandbox.m.dana.id/d/ipg/inputphone?ipgForwardUrl=%2Fd%2Fportal%2Fcashier%2Fcheckout%3FbizNo%3D20191120111212800110166711700294814%26timestamp%3D1574243577619%26originSourcePlatform%3DIPG%26mid%3D216620000000451758252%26sign%3DEUuaP%252Bv3VB90wR%252ByxacDNBhc9F0YHQdRkpYwToc7pp%252FKSEphzL7Oonlt4bA0DHUeAjKkMCb%252B7FqUR81OUudGuFOHTh8Y84OKh2dW24VqzQf%252Bw6TM8goPHGHjCGGohEgK1OEBvIsG%252FmNbbUYEuNPPiAGoWgyiYqdNRTexr%252FTzJipYG%252FQGzzFcccEBAca5GxRwocyvgQ80P3p7LEsPcbhLKnVOq64L6ZrGW7kdthIUVxzgip4WVDajrb8%252F9fXXQOM%252BVwGHiaAzah03sRqDF%252FwR%252BElY2Hpllfs%252F1UX8TtkFVnQP8ag%252FrL9OXzWryIVRgsLYXLkYkV4lA6l8Hb13Hfbcow%253D%253D");
    WebSettings webSettings = webView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webView.setWebViewClient(new WebViewClient() {
        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            webView.setVisibility(View.VISIBLE);
        }
    });

these two line is for scaling webview content 100%(Fit to screen):

    webView.getSettings().setLoadWithOverviewMode(true);
    webView.getSettings().setUseWideViewPort(true);

Add Permission in manifest.xml

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