我收到了这个片段，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();
}
但是当我执行它时崩溃了。这是logcat所说的：
