1
00:00:05,180 --> 00:00:11,590
Alright, so to play the videos using the Standalone Player, we used it to create videoIntent and create

2
00:00:11,590 --> 00:00:19,100
playlistIntent methods to get an Intent, that we then used to start an activity in Google's YouTube Player app.

3
00:00:19,100 --> 00:00:24,010
Now if we go back and check the documentation again for the YouTubeStandalonePlayer, just scroll down and

4
00:00:24,010 --> 00:00:28,270
have a look, there's an overloaded version of the createVideoIntent.

5
00:00:28,270 --> 00:00:32,310
You can see this one here, it's actually got three additional parameters.

6
00:00:32,310 --> 00:00:38,310
Now one is an integer called timeMillis, which is how far into the video, playback should start.

7
00:00:38,310 --> 00:00:41,760
We want to start at the beginning so we're going to use 0 for that one.

8
00:00:41,760 --> 00:00:43,650
Now the next one is the one we want,

9
00:00:43,650 --> 00:00:47,040
a Boolean called autoplay that starts playing immediately.

10
00:00:47,040 --> 00:00:50,310
So we're going to set that one to True, boolean autoplay as you can see there. I'll just scroll over so we can

11
00:00:50,310 --> 00:00:53,390
that a little bit better.

12
00:00:53,390 --> 00:00:55,820
Now the next one, the final parameter's interesting.

13
00:00:55,820 --> 00:00:59,560
It's a boolean called like lightboxMode, you see this up here,

14
00:00:59,560 --> 00:01:03,190
and that's set to False to play the video in full screen mode.

15
00:01:03,190 --> 00:01:08,260
We're going to use False for that here, but we'll experiment with it later to see what differences that

16
00:01:08,260 --> 00:01:09,670
makes setting that.

17
00:01:09,670 --> 00:01:15,940
So the first thing we need to do is go back to our code in Android Studio,

18
00:01:15,940 --> 00:01:23,890
and go back to our StandaloneActivity, and this is obviously the code where we created our Intent. Now at the moment you

19
00:01:23,890 --> 00:01:29,260
can see that we've got our YouTubeStandalonePlayer.createPlaylistIntent, and then on the previous

20
00:01:29,260 --> 00:01:34,900
line, on line 40, we've got YouTubeStandalonePlayer.createVideoIntent, and at the moment we haven't got all those additional

21
00:01:34,900 --> 00:01:37,570
arguments.

22
00:01:37,570 --> 00:01:41,610
So if you go ahead and make those changes now that we talked about, so firstly I'm going to come up after the

23
00:01:41,610 --> 00:01:48,310
YouTube video id comma space 0 comma space true.

24
00:01:48,310 --> 00:01:51,280
comma space false.

25
00:01:51,280 --> 00:01:56,420
That's those three arguments that we just talked about, and the next thing we need to do is create the

26
00:01:56,420 --> 00:02:03,320
PlaylistIntent, and just going back to the documentation again for the PlaylistIntent.

27
00:02:03,320 --> 00:02:07,490
You can see up here, we've got similar parameters for the PlaylistIntent.

28
00:02:07,490 --> 00:02:12,650
We've got timeMillis, boolean autoplay and boolean lightboxMode again.

29
00:02:12,650 --> 00:02:15,260
But there's also this additional parameter here,

30
00:02:15,260 --> 00:02:18,530
the fourth one, which comes before the other three:

31
00:02:18,530 --> 00:02:25,310
the start index, and that's used to start playing a specific video in the playlist, but

32
00:02:25,310 --> 00:02:29,540
we want to start with the first one so we're going to be using index zero there for that.

33
00:02:29,540 --> 00:02:32,810
Alright so let's go back to the code. So this is now for the PlaylistIntent,

34
00:02:32,810 --> 00:02:38,710
the second bit of code, we'll create PlaylistIntent. So after the Playlist we want to add 0 because we're

35
00:02:38,710 --> 00:02:43,900
starting from the first video, 0 again, true,

36
00:02:43,900 --> 00:02:48,350
and then for lightboxMode this time we're going to select true and see what that looks like.

37
00:02:48,350 --> 00:02:52,640
So that's the four arguments now for the createPlaylistIntent.

38
00:02:52,640 --> 00:02:58,340
So those should be the only two changes we need to make, and the videos we start from the Standalone menu

39
00:02:58,340 --> 00:03:00,680
should now start playing automatically.

40
00:03:00,680 --> 00:03:04,730
So we're going to run the program to see, so let's go back to our emulator

41
00:03:04,730 --> 00:03:13,160
first though. we're going to put it back in landscape mode.

42
00:03:13,160 --> 00:03:17,350
Alright, so I'm going to play the video, and go back and check it out.

43
00:03:17,350 --> 00:03:20,080
So first we need to go into the Standalone submenu.

44
00:03:20,080 --> 00:03:25,180
We're going to click on play video, and you can see that's now working. The Standalone submenu options for

45
00:03:25,180 --> 00:03:28,660
playing the video works, and the video started playing automatically.

46
00:03:28,660 --> 00:03:35,690
So I'll pause that, and we'll go back, click on Play Playlist, and you can see the video's also autoplaying there

47
00:03:35,690 --> 00:03:41,090
as well. So I'll pause that as well. Alright, now the Playlist videos do look a little bit different though,

48
00:03:41,090 --> 00:03:45,140
when I rotate the device into portrait. You can really see the difference, so

49
00:03:45,140 --> 00:03:49,520
basically instead of running full screen, the video is going to run in a dialogue on top of our activity.

50
00:03:49,520 --> 00:03:53,420
It's an interesting effect and it's nice to know that you can do that if you want to, so let's go back and see

51
00:03:53,420 --> 00:03:59,030
how that works. So what we'll do is we'll go back to portrait mode,

52
00:03:59,030 --> 00:04:03,940
and you can see that's overlaying there now. We'll play this, and just to see how that works, 

53
00:04:03,940 --> 00:04:10,020
and if I pause the video again and go back, click on Playlist, you can see how this lightboxMode effectively

54
00:04:10,020 --> 00:04:13,530
looks like a video that is for all intent purposes

55
00:04:13,530 --> 00:04:15,940
is playing over the top of our activity. It's an

56
00:04:15,940 --> 00:04:20,550
interesting effect there, but obviously it's still working in portrait mode which is good.

57
00:04:20,550 --> 00:04:25,980
So what's happening here is that Google had prevented the activities in their player from being destroyed

58
00:04:25,980 --> 00:04:27,870
when the orientation changes.

59
00:04:27,870 --> 00:04:30,720
And as I mentioned we will be seeing how to do that ourselves.

60
00:04:30,720 --> 00:04:35,700
So as a result of doing that, Google have also had to write code to cope with the change of orientation,

61
00:04:35,700 --> 00:04:40,020
and resize their layout themselves instead of relying on the default behavior.

62
00:04:40,020 --> 00:04:46,200
Now when the lightboxMode isn't used, the activity makes no attempt to handle the resolution change,

63
00:04:46,200 --> 00:04:51,630
which is why we get a landscape screen on the side. But in lightboxMode, Google have to deal with the resizing

64
00:04:51,630 --> 00:04:56,280
themselves, so it can be done if you decide to do that but it's quite a bit of extra coding.

65
00:04:56,280 --> 00:04:59,010
Alright, so that's the solution, or our solution to the challenge.

66
00:04:59,010 --> 00:05:01,820
Congratulations if you managed to complete it.

67
00:05:01,820 --> 00:05:06,140
So I'll finish the video here, and in the next one, we're going to have a look at that request code that we

68
00:05:06,140 --> 00:05:09,340
saw a few videos back. So I'll see you in the next video.
