Android：使用API​​等级11（或更高版本）的Youtube API

Question

我正在开发Android应用，我想在youtube中搜索给定查询的第一个结果。

首先，我开始使用以下网址：

"http://gdata.youtube.com/feeds/api/videos?q="+ query + "&max-results=1"

适用于Android API级别10（或更低），但不适用于API级别11（或更高级别）。

然后，我尝试使用 Youtube API 。我最初在SAXParser上有错误，但它运行正常。 再一次，它适用于API级别10（或更低），但不适用于API级别11（或更高级别）。

这是我的代码：

try{
    YouTubeQuery query = new YouTubeQuery(new URL("http://gdata.youtube.com/feeds/api/videos"));
    query.setOrderBy(YouTubeQuery.OrderBy.RELEVANCE);
    query.setFullTextQuery(pesquisa);
    query.setMaxResults(1);

    VideoFeed videoFeed = service.query(query, VideoFeed.class);

}
catch (Exception e) {
     Log.e("Exception", "exception", e);                    
}

此代码抛出以下异常（api> = 11）：

在youtube中进行简单查询的最佳方法是什么？

试试这个

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
