1
00:00:00,400 --> 00:00:03,120
We're going to test the app
at the end of this video.

2
00:00:03,120 --> 00:00:05,490
So now would be a good
time to pause me and

3
00:00:05,490 --> 00:00:09,150
start your emulator if it
isn't running already.

4
00:00:09,150 --> 00:00:13,600
We're ready to fill our new data model
object with data from the Dark Sky API.

5
00:00:14,660 --> 00:00:17,430
We're setting the current
weather in MainActivity.

6
00:00:17,430 --> 00:00:19,817
Lets open it up and have a look.

7
00:00:19,817 --> 00:00:24,670
So our MainActivity's here in
the ui package now, MainActivity.

8
00:00:24,670 --> 00:00:29,024
We have this getForecast method,
which is using

9
00:00:29,024 --> 00:00:34,133
the third party library OkHttp
to get data from Dark Sky.

10
00:00:34,133 --> 00:00:38,352
A successful request ends up calling
the onResponse method, down here.

11
00:00:42,952 --> 00:00:47,095
Line 82 shows that we are setting
the current weather using a method called

12
00:00:47,095 --> 00:00:48,335
getCurrentDetails.

13
00:00:49,630 --> 00:00:52,660
We can scroll down to where it's declared,
or

14
00:00:52,660 --> 00:00:55,290
there are some keyboard shortcuts as well.

15
00:00:55,290 --> 00:00:58,960
If you hold Cmd on a Mac or
the Ctrl key on Windows and

16
00:00:58,960 --> 00:01:05,690
click on the method name, Android Studio
will jump to where the method is declared.

17
00:01:05,690 --> 00:01:08,970
If you're interested in more
keyboard shortcuts like this,

18
00:01:08,970 --> 00:01:11,260
I've included links in the teachers notes.

19
00:01:11,260 --> 00:01:13,720
The links are to the IntelliJ website,

20
00:01:13,720 --> 00:01:16,670
which is the base tool that
Android Studio is built upon.

21
00:01:18,160 --> 00:01:23,310
The code inside getCurrentDetails methods
here is using the JSONObject class

22
00:01:23,310 --> 00:01:27,550
to convert the string of JSON
data received from the API

23
00:01:27,550 --> 00:01:31,660
into a Java object that we can access and
manipulate.

24
00:01:31,660 --> 00:01:34,370
We're filling up the current model object,

25
00:01:34,370 --> 00:01:38,250
fortunately we can leave most
of this code totally alone.

26
00:01:38,250 --> 00:01:41,027
But we now want to fill up
the whole forecast object and

27
00:01:41,027 --> 00:01:43,350
not just the current object.

28
00:01:43,350 --> 00:01:45,890
Let's add a new method to do just that.

29
00:01:45,890 --> 00:01:49,330
And in this new method,
we can call getCurrentDetails,

30
00:01:49,330 --> 00:01:52,190
as well as new methods to get
the hourly forecast details.

31
00:01:53,290 --> 00:01:57,732
So above getCurrentDetails,
let's add some space.

32
00:01:57,732 --> 00:02:00,125
Our new method will be private.

33
00:02:00,125 --> 00:02:02,170
It will return a Forecast.

34
00:02:02,170 --> 00:02:04,230
Let's call it parseForecastData.

35
00:02:06,980 --> 00:02:09,156
And it'll take a string of jsonData.

36
00:02:12,628 --> 00:02:14,350
Now, first, we need a Forecast variable.

37
00:02:16,700 --> 00:02:20,069
Forecast, we'll call it Forecast,
and it'll be new Forecast.

38
00:02:23,185 --> 00:02:27,690
Once we get done building that object,
this is what we'll return.

39
00:02:27,690 --> 00:02:29,989
Before we forget, let's return it.

40
00:02:33,928 --> 00:02:38,300
Our forecast object has a member
variable for the current forecast.

41
00:02:38,300 --> 00:02:41,000
We generated a setter method for
it inside our model.

42
00:02:42,130 --> 00:02:43,513
So we can set that up here.

43
00:02:45,557 --> 00:02:50,850
Forecast.setCurrent, which
takes a current object.

44
00:02:50,850 --> 00:02:55,414
And in here we can just call
the getCurrentDetails method directly,

45
00:02:55,414 --> 00:02:59,670
since it returns a current object for
us, getCurrentDetails.

46
00:02:59,670 --> 00:03:06,631
Now we'll pass along the same jsonData
stream we're using for our method And

47
00:03:06,631 --> 00:03:12,860
we get an unhandled JSON exception error
because getCurrentDetails throws one.

48
00:03:12,860 --> 00:03:15,760
Let's throw it again,
as we're going to call this new method

49
00:03:15,760 --> 00:03:18,740
from the same place we were
previously calling getCurrentDetails.

50
00:03:19,750 --> 00:03:23,470
We can use the quick fix to add
throws JSONException to this method.

51
00:03:26,040 --> 00:03:30,005
Let's update our code now to set the whole
forecast instead of just the current

52
00:03:30,005 --> 00:03:31,155
weather conditions.

53
00:03:31,155 --> 00:03:32,608
We will go all the way back up to the top.

54
00:03:37,335 --> 00:03:39,820
We'll replace this current
variable with a forecast.

55
00:03:41,270 --> 00:03:44,960
Forecast forecast, and there we go.

56
00:03:46,140 --> 00:03:48,934
And now onto the error hunt to fix things.

57
00:03:48,934 --> 00:03:52,272
We can either scroll
down to the new error or

58
00:03:52,272 --> 00:03:55,920
click on it over here
on the right-hand side.

59
00:03:55,920 --> 00:04:00,670
This line here, line 83,
is taken care of inside our new method.

60
00:04:00,670 --> 00:04:03,461
We can replace it with our forecast.

61
00:04:03,461 --> 00:04:10,450
So forecast, And
we use the same jsonData string.

62
00:04:11,470 --> 00:04:15,540
But now instead of getCurrentDetails,
we want parseForecastData.

63
00:04:15,540 --> 00:04:20,090
There are a few more errors here caused
by removing the current member variable.

64
00:04:20,090 --> 00:04:21,220
We go down to those and

65
00:04:21,220 --> 00:04:25,010
we simply need to access this
through the forecast variable now.

66
00:04:25,010 --> 00:04:28,625
Let's add a new variable here just
to make it a little bit easier.

67
00:04:32,110 --> 00:04:34,517
So Current,
our variable name down there is current.

68
00:04:37,597 --> 00:04:40,387
And that'll be forecast and getCurrent.

69
00:04:42,410 --> 00:04:51,700
Let's test it out Very nice.

70
00:04:51,700 --> 00:04:53,450
All of our data is still being displayed.
