Answer 1

    webview_id = (WebView)findViewById(R.id.webview_id);
    webview_id.getSettings().setJavaScriptEnabled(true); // enable javascript
    WebSettings webSettings = webview_id.getSettings();
    webSettings.setBuiltInZoomControls(true);
    webSettings.setDisplayZoomControls(true);
    webSettings.setPluginState(WebSettings.PluginState.ON);
    webSettings.setJavaScriptEnabled(true);
    webview_id.setInitialScale(90);
    webSettings.setLoadWithOverviewMode(true);
    webview_id.requestFocusFromTouch();
    webview_id.setWebViewClient(new WebViewClient() {
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            Snackbar.with(getApplicationContext()).dismiss();
            Snackbar.with(getApplicationContext()) // context
                    .text(description) // text to display
                    .show(MainActivity.this);
        }
        public void onPageFinished(WebView view, String url) {
            progressBar.setVisibility(View.GONE);
        }
    });


    if(isNetworkAvailable()){

        webview_id .loadUrl("http://helloworld.org/");
    }else{
        Snackbar.with(getApplicationContext()).dismiss();
        Snackbar.with(getApplicationContext()) // context
                .text("Please Check your Internet Connection") // text to display
                .show(MainActivity.this);
        progressBar.setVisibility(View.VISIBLE);
    }
}
