Question

我在Android应用程序中遇到了一个问题，我无法从网站获取特定数据。我的应用程序崩溃了。这是我的代码：

    private void AddListenerOnButton() {
    spinner = (Spinner) getView().findViewById(R.id.spinner);
    final WebView webView = (WebView) getView().findViewById(R.id.webView1);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setRenderPriority(RenderPriority.HIGH);
    webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
    webView.getSettings().setDatabaseEnabled(true);
    webView.getSettings().setDomStorageEnabled(true);
    webView.getSettings().setAppCacheEnabled(true);
    webView.getSettings().setBuiltInZoomControls(true);

    spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
            String text1 = spinner.getSelectedItem().toString().trim();
            //WebClient wc = new WebClient();

            if (text1.equals("US Dollar - USD")) {          
                try {
                    Document doc = Jsoup.connect("http://en.wikipedia.org/").get();
                    Elements newsHeadlines = doc.select("#mp-itn b a");

                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

这是我的logcat：

这里发生了什么？我似乎无法理解发生了什么。任何帮助将不胜感激。

这条线是线索......

java.lang.NoClassDefFoundError: org.jsoup.Jsoup

您的应用程序在运行时找不到Jsoup库。不幸的是，我可以告诉你为什么我可以看到，但这里有一个链接，有很多很好的理由和修复......

Android java.lang.NoClassDefFoundError: org.jsoup.Jsoup
