1. Title:
   Quick Code Overview
2. Description:

3. 310 0:00 - 0:02
   Let's take a quick look
   at the layout of the app.
4. 2270 0:02 - 0:05
   Here are the Java classes.
5. 5100 0:05 - 0:10
   The Dinner class has methods for
   figuring out what dinner to suggest.
6. 9510 0:10 - 0:13
   The MainActivity shows the main screen.
7. 12990 0:13 - 0:17
   To start with the main screen only has
   this one button, What's for dinner?
8. 17360 0:17 - 0:21
   And when you press the button
   it fires off an intent
9. 20760 0:21 - 0:22
   to the show dinner activity.
10. 22088 0:22 - 0:26
    So the dinner shows here and
    then you get these buttons.
11. 26300 0:26 - 0:30
    And each of these buttons fires off
    an intent to start the appropriate
12. 29790 0:30 - 0:31
    activity.
13. 30670 0:31 - 0:31
    So for example,
14. 31390 0:31 - 0:36
    the Show Recipe button sends an intent
    to start the show recipe activity.
15. 36470 0:36 - 0:40
    And actually, Choose Again does
    not have a corresponding activity,
16. 39740 0:40 - 0:42
    it just has a method inside the class.
17. 42020 0:42 - 0:46
    Now this class here,
    the useInfoBoxFragment
18. 46170 0:46 - 0:50
    is a fragment that simply displays
    an info box and a heading.
19. 50770 0:51 - 0:54
    This lets you reuse the fragment
    wherever you need it, and
20. 53760 0:54 - 0:55
    helps simplify the code.
21. 55400 0:55 - 1:00
    And for example, the showRecipeActivity,
    the removeMealActivity,
22. 60260 1:00 - 1:04
    the orderDinnerActivity,
    all these activities use this fragment.
23. 64410 1:04 - 1:06
    And the app has a couple of menus.
24. 66200 1:06 - 1:10
    There's the main menu,
    which just shows the settings.
25. 69500 1:10 - 1:13
    But actually, we're not going to use
    the settings in this application.
26. 72980 1:13 - 1:19
    More interestingly, the food prefs menu,
    displays a list of food options.
27. 78720 1:19 - 1:24
    This pop-up is used whenever we want
    the user, choose the food preference.
28. 84010 1:24 - 1:27
    There's one other quick
    thing I want to mention.
29. 86840 1:27 - 1:29
    In the intro lesson to this
    course you learned how to
30. 89450 1:29 - 1:34
    implement the unconnected code to
    use the Google API Client Library.
31. 94250 1:34 - 1:38
    However, for both Google Analytics and
    Google Tag Manager,
32. 97790 1:38 - 1:43
    you do not need to implement any code
    to use the Google API Client Library.
33. 102540 1:43 - 1:47
    All the app needs is to specify
    the version of the client library
34. 107040 1:47 - 1:50
    in the android manifest, like this.
35. 109540 1:50 - 1:55
    And to specify the dependency on
    play-services in the build.gradle file.
36. 115030 1:55 - 1:59
    And these dependencies have already
    been set up for you in the What's For
37. 118560 1:59 - 1:59
    Dinner sample app.
