1
00:00:02,390 --> 00:00:04,640
So what will we build in this module?

2
00:00:04,670 --> 00:00:11,390
We'll build a simple app and in this app, I'll not focus too much on the app itself, we'll build a basic

3
00:00:11,390 --> 00:00:17,240
app here, we'll not add too many features because I instead want to focus on all these core native device

4
00:00:17,240 --> 00:00:17,930
features.

5
00:00:18,080 --> 00:00:24,140
So we'll build a a simple application which allows us to manage some great places we found let's say.

6
00:00:24,530 --> 00:00:29,820
So on the starting screen, we'll have a list of those places where we maybe have an image,

7
00:00:29,930 --> 00:00:36,110
then the title and then here, the address of that place and we'll have such a list here where we

8
00:00:36,110 --> 00:00:38,090
can view all these places.

9
00:00:38,090 --> 00:00:46,130
Now once we tap such a place, we're taken to the detail screen for that place where we see a bigger

10
00:00:46,130 --> 00:00:56,510
image, where we then also see the address and below that, we see a map preview which we can also tap to

11
00:00:56,510 --> 00:00:58,780
open a full screen map,

12
00:00:58,790 --> 00:01:05,360
so to go to a new screen essentially where we of course also can go back, just as we can go back here

13
00:01:05,390 --> 00:01:06,130
by the way,

14
00:01:06,260 --> 00:01:12,320
so where we can go back, where we then see a full screen map representation of that place.

15
00:01:12,320 --> 00:01:19,790
Now of course to add new places, we'll have a way of doing that, we'll have a plus or a create button here

16
00:01:19,880 --> 00:01:20,950
in the menu

17
00:01:21,020 --> 00:01:29,120
and when we tap this button, we're taken to yet another new screen which allows us to add a place.

18
00:01:29,120 --> 00:01:36,080
Now on this screen, we can enter a title with a regular text input but we can also and that's now the

19
00:01:36,080 --> 00:01:37,440
interesting part,

20
00:01:37,490 --> 00:01:40,790
we can also take an image and display a preview here,

21
00:01:40,790 --> 00:01:50,960
so we have a take image button here below that which we can press and that should open up the device camera

22
00:01:50,990 --> 00:01:58,010
of course so that we can take a photo with the device camera and below that, I will also have

23
00:01:58,010 --> 00:02:02,180
a map preview and we can locate the user,

24
00:02:02,210 --> 00:02:14,170
so we have a locate button here or a choose on map button which obviously should fit onto the page and

25
00:02:14,350 --> 00:02:15,230
not overlap it.

26
00:02:15,340 --> 00:02:20,260
But these are the two buttons we'll have here - choose on map and locate and that will then either

27
00:02:20,260 --> 00:02:26,020
pick the location where the user is currently at and populate this map preview with it or if we click

28
00:02:26,020 --> 00:02:29,880
choose on map, we'll also open that full screen map here

29
00:02:30,040 --> 00:02:35,200
but now in a mode where we can tap on a place there and then this place will be selected and we can

30
00:02:35,200 --> 00:02:43,120
then click save up here to save that place and use that place here for this screen and there ultimately,

31
00:02:43,120 --> 00:02:46,810
we'll also have a save button which we can press to add this new place.

32
00:02:47,020 --> 00:02:54,690
Now new places will be stored in a SQLite database.

33
00:02:54,690 --> 00:02:59,790
Now of course, you might want to store them on a web server but you already learned how that would work.

34
00:02:59,790 --> 00:03:05,160
So in this module, I want to focus on a new storage technique which you also need in some apps where you

35
00:03:05,160 --> 00:03:08,290
store something on the device, in an on device database

36
00:03:08,520 --> 00:03:14,580
and that is of course also a common scenario, not all data needs to be stored on web servers. Maybe you

37
00:03:14,580 --> 00:03:18,960
have an app where you need to store everything on a web server but you also might have some data in

38
00:03:18,960 --> 00:03:22,580
some apps which you only need to store locally on the device.

39
00:03:22,590 --> 00:03:26,470
The advantage of storing it locally of course is that you need no Internet connection,

40
00:03:26,490 --> 00:03:29,210
the disadvantages that it can't be shared with other users

41
00:03:29,220 --> 00:03:34,640
but if it's exclusive to this app installation, then you might absolutely want to store it locally.

42
00:03:34,710 --> 00:03:39,720
So therefore this is what we're about to build. Regarding the navigation and so on, it's not the most complex

43
00:03:39,720 --> 00:03:46,140
app because we had plenty of practice with that but we'll have plenty of amazing native device features

44
00:03:46,140 --> 00:03:51,160
in there - camera, maps, user location, files storage and also SQLite,

45
00:03:51,180 --> 00:03:56,310
so with that, you'll have a solid understanding of how to tap into such features and add them to your application

46
00:03:56,490 --> 00:03:58,050
when you're done with this module.
