1
00:00:02,750 --> 00:00:04,060
So now for the important part,

2
00:00:04,070 --> 00:00:08,990
testing this on a real phone. For this, I'm reinstalling the expo client on my iPhone so that all the permissions

3
00:00:08,990 --> 00:00:13,940
I did set up there in the past during testing and so on are reset so that they can show this from scratch

4
00:00:14,450 --> 00:00:20,330
and I opened up my expo dev window in the browser here, it was always open but now I brought it on

5
00:00:20,390 --> 00:00:24,050
the screen so that we have the barcode there to scan.

6
00:00:24,050 --> 00:00:29,840
So with that, we can of course scan this with the help of the camera application here which I point

7
00:00:29,840 --> 00:00:35,090
that the barcode so that I can tap this to open it, on Android you have the scanner in the expo app

8
00:00:35,250 --> 00:00:37,600
but I'll show this in a second.

9
00:00:37,700 --> 00:00:38,530
Got that,

10
00:00:38,630 --> 00:00:43,740
here's the app and now I can add a place, test this

11
00:00:43,760 --> 00:00:45,350
and now you'll see something interesting.

12
00:00:45,350 --> 00:00:48,760
If I click take image, I'm asked for permissions and I click

13
00:00:48,800 --> 00:00:51,800
okay but now this will actually fail.

14
00:00:51,920 --> 00:00:53,570
You see that warning here at the bottom,

15
00:00:53,600 --> 00:00:55,510
this failed.

16
00:00:55,550 --> 00:00:59,750
Now the reason for why this failed is that I'm asking for the wrong permission here in the image

17
00:00:59,750 --> 00:01:00,510
picker.

18
00:01:00,530 --> 00:01:04,760
Now previously, I had to change this because on the simulator, I was also getting an error

19
00:01:04,760 --> 00:01:10,760
there. Now this should actually be fixed by not just asking for the camera roll permission here but also,

20
00:01:11,090 --> 00:01:14,520
we can simply add a second argument here, for permissions camera,

21
00:01:14,540 --> 00:01:17,250
so we need both - camera and camera roll.

22
00:01:17,420 --> 00:01:22,190
Now previously, changing this to camera roll fixed the issue because we did ask for the camera permission

23
00:01:22,190 --> 00:01:28,400
first but in the end, you need to ask for both and whenever you reinstall the expo client or relaunched

24
00:01:28,400 --> 00:01:32,210
the app on a new device, you definitely need to ask for both

25
00:01:32,210 --> 00:01:35,590
for this to work. So make sure you do ask for both

26
00:01:35,660 --> 00:01:38,240
and with that added, with both permissions added here,

27
00:01:38,240 --> 00:01:42,500
this will now always work because now we're asking for both permissions even though we're only using

28
00:01:42,500 --> 00:01:43,660
the camera here

29
00:01:43,850 --> 00:01:50,330
but since this package could also use the camera roll, we need to get both permissions and thereafter,

30
00:01:50,390 --> 00:01:53,790
close expo and rescan that barcode here,

31
00:01:56,540 --> 00:02:00,160
like this and open this in expo again and now it should work.

32
00:02:00,150 --> 00:02:10,100
So now if we go here and we enter test here and then I take an image, now I'm asked for whether I want

33
00:02:10,100 --> 00:02:17,450
to grant access and I do and now I'll take this amazing image here which is very meta because I take

34
00:02:17,450 --> 00:02:22,820
an image of the screen where I record that I take an image and I can use that photo,

35
00:02:22,820 --> 00:02:27,640
here it is and now let's choose a location on the map,

36
00:02:27,680 --> 00:02:29,410
maybe this one, save

37
00:02:29,420 --> 00:02:35,060
this, seems to work or get my current location which I don't want to here, so I'll just click

38
00:02:35,060 --> 00:02:36,560
save place

39
00:02:36,560 --> 00:02:40,540
and here it is, add it, you can view it, you can view the details.

40
00:02:40,580 --> 00:02:41,540
So this seems to work

41
00:02:41,540 --> 00:02:47,930
and now let me also close this and reopen it so that we see whether it was really stored in a database.

42
00:02:48,080 --> 00:02:53,320
So it should now load this place hopefully and it does and all the data is there.

43
00:02:53,330 --> 00:03:00,290
So this is now our application running on a real iPhone and we fixed this important permission error,

44
00:03:00,350 --> 00:03:03,230
let's now also run it on an Android device.
