JSoup.connect（String url）。java.lang.ExceptionInInitializerError .get

Question

我在Android AIR原生擴展中遇到了JSoup的奇怪問題。

我試圖從YouTube加載一個頁面以從評論中提取一些數據。

這裏是 「得罪」 代碼：

private class ConnectToYouTube { 
    public String html = null; 
    public Exception error = null; 
} 

private class ConnectToYouTubeTask extends AsyncTask<String, Void, ConnectToYouTubeResult> 
{ 
    @Override 
    protected ConnectToYouTubeResult doInBackground(String... params) 
    { 
     ConnectToYouTubeResult result = new ConnectToYouTubeResult(); 

     String videoId = params[0]; 

     try { 
      Document doc = Jsoup.connect("http://www.youtube.com/watch?v="+videoId).get(); // in the catlog this is line 138 
      Elements foo = doc.select("#comment-text"); 
      result.html = foo.html(); 
     } catch (IOException e) { 
      result.error = e; 
     } 

     return result; 
    } 
}

是@ user1814155是正確的，我花2天這樣的：d

Make sure the Jsoup library is in the Libs folder. I spend a good 2 hours banging my head against this error when that was the problem. Hope this helps, cheers. – user1814155
