Android : Pass WebView data between activity

My question is i hope simple. I have my site but is very heavy, and i want to display that site into WebView.

For example:

Can i load the website into MainActivity and pass data into WebActivity for display this data in another webview? and interact with that?

Example:

MainActivity:

 webView = (WebView) findViewById(R.id.webview);
        webView.measure(100, 100);

        WebSettings settings = webView.getSettings();

        settings.setLoadWithOverviewMode(true);
        settings.setJavaScriptEnabled(true);

        webView.setWebViewClient(new WebViewClient() {

            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);

                return true;
            }

            @SuppressLint("NewApi")
            @Override
            public void onReceivedSslError(WebView view, SslErrorHandler handler,     SslError error) {
                super.onReceivedSslError(view, handler, error);

                handler.proceed();
            }
        });

        if (savedInstanceState != null)
            webView.restoreState(savedInstanceState);

        else{

        webView.postUrl("https://site", EncodingUtils.getBytes(data, "base64"));

        }
    }

Now i must use webView.saveState?

i don't know if I did understand..
