我正在開發一個Android應用程序,我想在給定的查詢中搜索youtube中的第一個結果。Android:使用API Level 11(或更高版本)的Youtube API
首先,我開始使用以下網址:
"http://gdata.youtube.com/feeds/api/videos?q="+ query + "&max-results=1"
它的工作原理很好的爲Android API級別10(或更少),但它並不適用於API級別11(或更高版本)的工作。
然後,我嘗試使用Youtube API。我最初有SAXParser錯誤,但後來它工作正常。 再一次,它可以很好地適用於API級別10(或更低),但不適用於API級別11(或更高級別)。
這裏是我的代碼:
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);
}
此代碼拋出以下異常(API> = 11):

什麼是做在YouTube上簡單查詢的最佳方式?
是什麼,您有什麼似乎是確切的問題,即在api 10中工作但不是11? – 2012-01-29 21:53:53
當我使用API 11時,它會在此行中引發異常: 'VideoFeed videoFeed = service.query(query,VideoFeed.class);' 當我使用api 10時,我可以獲取視頻。 – TGomews 2012-01-30 15:11:48
你可以在你原來的帖子中發佈異常嗎? – 2012-01-30 19:28:59
