推荐答案

经过研究我得到了答案，现在它在 4.4.2 上顺利运行.

After research I got my answer and now its running smoothly on 4.4.2.

public class WebViewTwo extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.web_view_two);

    WebView webView = (WebView) findViewById(R.id.webView2);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.setWebViewClient(new HelloWebViewClient());

    webView.loadUrl("http://www.google.co.in");
}

private class HelloWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {

        view.loadUrl(url);
        return true;
    }
}}
