Question

I’m trying to get the browser function in my Android application to work but the application crashes upon load. Here’s the code when the new activity is loaded:

@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);
}

And here is the LogCat:

How can I fix this problem?

Thanks in advance.

Try this, And let me know what happen

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

getWindow().requestFeature(Window.FEATURE_PROGRESS);
    WebView webview = new WebView(this);
    WebSettings webSettings = webview.getSettings();
    webSettings.setJavaScriptEnabled(true);
    setContentView(webview);

    webview.loadUrl("http://erik-edgren.nu/weather");
}
