My basic code is:

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.display);


        progress = (ProgressBar) findViewById(R.id.progressBar1);
        webview = (WebView) findViewById(R.id.webView1);
        webSettings = webview.getSettings();
        webSettings.setBuiltInZoomControls(true);
        webSettings.setJavaScriptEnabled(true);
