我尝试使用android webview加载.jsp网页,但是webview打开时显示空白页面。在Chrome浏览器应用中成功加载了相同的网页。我尝试使用www.google.co.in加载相同的webview并且工作。这是我的代码。

 WebView webView = (WebView) view.findViewById(R.id.webView);
    webView.getSettings().setJavaScriptEnabled(true);

    webView.setWebViewClient(new WebViewClient() {
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            webViewProgressBar.setVisibility(View.VISIBLE);
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            webViewProgressBar.setVisibility(View.GONE);
        }


    });
webView.loadUrl(url);

提前致谢。

由于ssl异常,这种情况正在发生。要根据新的安全策略正确处理SSL证书验证并避免Google拒绝应用程序,只要服务器提供的证书符合您的期望,就更改您的代码以调用SslErrorHandler.proceed(),否则调用SslErrorHandler.cancel()。

例如,

@Override
    public void onReceivedSslError(WebView view, final SslErrorHandler handler, SslError error) {
    final AlertDialog.Builder builder = new AlertDialog.Builder(this);
    String message = "SSL Certificate error.";
        switch (error.getPrimaryError()) {
            case SslError.SSL_UNTRUSTED:
                message = "The certificate authority is not trusted.";
                break;
            case SslError.SSL_EXPIRED:
                message = "The certificate has expired.";
                break;
            case SslError.SSL_IDMISMATCH:
                message = "The certificate Hostname mismatch.";
                break;
            case SslError.SSL_NOTYETVALID:
                message = "The certificate is not yet valid.";
                break;
        }
        message += " Do you want to continue anyway?";

        builder.setTitle("SSL Certificate Error");
        builder.setMessage(message);
    builder.setPositiveButton("continue", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            handler.proceed();
        }
    });
    builder.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            handler.cancel();
        }
    });
    final AlertDialog dialog = builder.create();
    dialog.show();
}

更改后,它不会显示警告。
