Dear All,
I am a beginner in Android and I have to develop an application that plays
video from YouTube.com. I have playlist and some videos in it so I have to
list these videos first. I populated playlists in my list view but I cannot
extract videos list in playlist. It is giving me XML parsing exception. Can
you help me?
My code is as below.
class YoutubeServices {
private YouTubeService youTubeService;
private PlaylistLinkFeed feed;
private List<PlaylistLinkEntry> entries;
private String urlForPlaylist =
"http://gdata.youtube.com/feeds/api/users/YpyHr_nAd4lQo3FvQeNo1Q/playlists?v2";;
private String urlToDownloadAtomOfVideo =
"http://gdata.youtube.com/feeds/api/users/YpyHr_nAd4lQo3FvQeNo1Q/playlists/";;
private String playlist[][] = new String[3][];
private String playlistVideosList[][] = new String[3][];
//One calls this class as below.
//YoutubeServices m = new YoutubeServices("emailaddress", "password");
//m.getData();
//m.getVideosFromPlaylist("PlayListID");
public Main(String username, String password) {
youTubeService = new YouTubeService("App Name",
"AI39sixxxxxxxxxxx<<<< This is developers key >>>>xxxxxxxxxxxxxxxxxxxx");
Log.d("","YouTube Service is created.");
//youTubeService.setUserCredentials("emailaddress", "password");
try {
youTubeService.setUserCredentials(username, password);
} catch (AuthenticationException e) {
Log.d("AuthenticationException", ""+e);
}
}
public String[][] getData(){
try {
URL playlistUrl = new URL(urlForPlaylist);
feed = youTubeService.getFeed(playlistUrl, PlaylistLinkFeed.class);
entries = feed.getEntries();
playlist = new String[3][entries.size()];
for(int i=0; i<entries.size(); i++){
playlist[0][i] = entries.get(0).getTitle().getPlainText();
Log.d("Title ", ""+entries.get(0).getTitle().getPlainText());
playlist[1][i] = entries.get(0).getSummary().getPlainText();
Log.d("Description " , ""+entries.get(0).getSummary().getPlainText());
playlist[2][i] = entries.get(0).getId();
Log.d("ID ", ""+entries.get(0).getId());
}
} catch (MalformedURLException e) {
Log.d("MalformedURLException Error ", ""+e);
} catch (IOException e) {
Log.d("IOException Error ", ""+e);
} catch (ServiceException e) {
Log.d("ServiceException Error ", ""+e);
}
for(int i=0; i<playlist.length; i++){
for(int j=0; j<playlist[i].length; j++){
Log.d("", ""+playlist[i][j]);
}
}
return playlist;
}
public String[][] getVideosFromPlaylist(String playList){
URL playlistUrl;
try {
playlistUrl = new URL(urlToDownloadAtomOfVideo+playList+"?v2");
Log.d("URL", ""+urlToDownloadAtomOfVideo+playList+"?v2");
YouTubeQuery query = new YouTubeQuery(playlistUrl);
//Here I have error
VideoFeed videoFeed = youTubeService.query(query, VideoFeed.class);
for(VideoEntry entry : videoFeed.getEntries()){
Log.d("Title",""+entry.getTitle().getPlainText());
Log.d("Summery",""+entry.getSummary().getPlainText());
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (ServiceException e) {
e.printStackTrace();
}
return playlistVideosList;
}
}
