我得到了这个片段，它应该是来自youtube的某些视频的标题。
public static void getVids() {
try {
YouTubeService myService = new YouTubeService("mycompany-myapp-1");
String myFeed = "http://gdata.youtube.com/feeds/videos?start-index=1&max-results=25&vq=lizards&oi=spell";
printVideoFeed(myService, myFeed);
} catch (IOException ex) {
Toast toast = Toast.makeText(null, "Error "+ex.toString(), 5000);
toast.show();
} catch (ServiceException ex) {
Toast toast = Toast.makeText(null, "Error "+ex.toString(), 5000);
toast.show();
}
}
private static void printVideoFeed(YouTubeService service, String feedUrl) throws IOException, ServiceException {
VideoFeed videoFeed = service.getFeed(new URL(feedUrl), VideoFeed.class);
List<VideoEntry> allVideos = videoFeed.getEntries();
Iterator<VideoEntry> itAllVideos = allVideos.iterator();
String Titles = "";
while (itAllVideos.hasNext()){
VideoEntry oneVideo = itAllVideos.next();
TextConstruct oneVideoTitle = oneVideo.getTitle();
Titles = Titles + " | " + oneVideoTitle.toString();
}
Toast toast = Toast.makeText(null, "Working! " + Titles , 5000);
toast.show();
}
但是当我执行它时它崩溃了。下面是logcat说的:

你认为可能是什么问题?
谢谢!
我也遇到过类似的问题。解决方案应该是用这里找到的JavaMail库替换您的JavaMail库(JavaMail for Android)。
直接来自YouTube API团队:"我的理解是Java Google Data客户端库目前与Android运行时环境不兼容。"
这个链接是我找到答案的地方，以及你看到的错误消息。
