我试图让我的Android应用程序中的浏览器功能正常工作，但应用程序在加载时崩溃。下面是当新的活动被加载代码：应用程序在加载浏览器时崩溃
@Override
public void onCreate(Bundle savedInstanceState) {
WebView webview = new WebView(this);
setContentView(webview);
webview.loadUrl("http://erik-edgren.nu/weather");
getWindow().requestFeature(Window.FEATURE_PROGRESS);
WebSettings webSettings = webview.getSettings();
webSettings.setJavaScriptEnabled(true);
}
这里是logcat的：

对不起，我忘了把super.onCreate（savedInstanceState）; onCreate（）的起始行。 – user370305 2012-04-05 14:07:26
