1

00:00:00,330 --> 00:00:06,750

So because you want to access the user's location you need to create value but of type fuse location



2

00:00:06,750 --> 00:00:08,000

provide that API.



3

00:00:08,070 --> 00:00:08,930

So what is this class.



4

00:00:08,940 --> 00:00:10,450

Let's go to the Android documentation.



5

00:00:10,450 --> 00:00:15,660

Any in here just enter this you are a developer that and dot com slash index that.



6

00:00:15,720 --> 00:00:16,800

TMF OK.



7

00:00:16,980 --> 00:00:24,270

So inside the search bar just typing here fused location provided API so it can actually give us this



8

00:00:24,540 --> 00:00:24,860

link.



9

00:00:24,870 --> 00:00:26,290

It says in Google said it's true.



10

00:00:26,330 --> 00:00:27,380

So just click on it.



11

00:00:28,320 --> 00:00:30,030

Let's wait a little bit here.



12

00:00:30,090 --> 00:00:30,950

So it's going up.



13

00:00:30,960 --> 00:00:35,250

Open this page for us to fuse location provide that API.



14

00:00:35,430 --> 00:00:39,440

So it says public interface views like kitchen pro-white API.



15

00:00:39,450 --> 00:00:42,110

So this is actually an interface right.



16

00:00:42,150 --> 00:00:46,800

The main entry point for interacting with diffused the location pro-white there.



17

00:00:47,040 --> 00:00:53,670

So we must have access to these actually use the location provide that API in order to access the user's



18

00:00:53,670 --> 00:00:54,420

location.



19

00:00:54,600 --> 00:00:56,640

Okay this is actually the main entry point.



20

00:00:56,640 --> 00:00:58,200

This is very important.



21

00:00:58,260 --> 00:01:04,470

The method must be used in conjunction with the Google API client so you can see this here it is familiar



22

00:01:04,470 --> 00:01:09,840

to you you already use this piece of code inside are actually the uncreate method in order to initialize



23

00:01:09,840 --> 00:01:12,550

our Google API client instance right.



24

00:01:12,630 --> 00:01:20,600

So you can see this here and now you can see it is constancy a key location change the key marked location.



25

00:01:20,610 --> 00:01:22,360

And let's actually look at these methods.



26

00:01:22,470 --> 00:01:28,800

For example this one pending glissade it says flushers any location is currently being patched and sends



27

00:01:28,800 --> 00:01:36,030

them to all registers and we have the location update it says returns the best most recent location.



28

00:01:36,030 --> 00:01:41,520

Currently available look at this if it here gets last location so we are going to use this method in



29

00:01:41,520 --> 00:01:46,220

order to access that user's location we have location availability here.



30

00:01:46,320 --> 00:01:51,690

So it is actually called returns the availability of location data right.



31

00:01:51,940 --> 00:01:53,450

And all these if it's.



32

00:01:53,550 --> 00:01:54,180

Right.



33

00:01:54,470 --> 00:01:58,480

And we can see that can actually give us some descriptions about these methods.



34

00:01:58,480 --> 00:02:04,590

So this is them for that we are going to use GET last location insets returns the best most recent location



35

00:02:04,620 --> 00:02:05,900

currently available.



36

00:02:05,970 --> 00:02:12,700

If a location is not available which should happen very rarely null will be returned.



37

00:02:12,860 --> 00:02:18,670

Okay the best accuracy available while respecting the location permissions will be returned.



38

00:02:18,660 --> 00:02:23,120

This provides a simplified way to get location.



39

00:02:23,130 --> 00:02:30,660

It is particularly well suited for applications that do not require an accurate location and that do



40

00:02:30,660 --> 00:02:36,310

not actually want to maintain extra logic for allocation updates updates.



41

00:02:36,690 --> 00:02:37,800

So that's enough.



42

00:02:37,800 --> 00:02:44,100

Let's actually go to our Android studio and inside the curly braces of this statement I can actually



43

00:02:44,100 --> 00:02:50,220

create a value of idea but of type fuse location provide that API and the name is going to be just the



44

00:02:50,220 --> 00:02:54,560

fuse location provide that API and puts an assignment operator here.



45

00:02:54,720 --> 00:02:58,840

So because the fuse location pro-white that API is an interface.



46

00:02:58,920 --> 00:03:04,210

This means that we cannot create an object by using the new keyboard.



47

00:03:04,420 --> 00:03:05,090

OK.



48

00:03:05,550 --> 00:03:06,820

So just typing here.



49

00:03:06,870 --> 00:03:10,920

Location services that fused.



50

00:03:10,950 --> 00:03:15,780

So I just need to put a capital F that fuse location API semi-colon.



51

00:03:15,930 --> 00:03:19,140

So now its going actually to give us the fuse location API.



52

00:03:19,140 --> 00:03:24,750

So now this variable holds that right the main entry port in order to actually access the user's location.



53

00:03:24,750 --> 00:03:28,000

So let me actually create a new line here so that you can see this value better.



54

00:03:28,320 --> 00:03:35,070

So now it's time to initialize our location rowdier but that we declared inside our main activity class.



55

00:03:35,070 --> 00:03:36,230

So let me scroll to the top.



56

00:03:36,270 --> 00:03:43,110

You can see this variable here location and we have not yet initialized this location very well so now



57

00:03:43,140 --> 00:03:44,090

it's time to do that.



58

00:03:44,100 --> 00:03:48,950

Let's actually scroll down here and let's go inside this show they use their location method after this



59

00:03:48,950 --> 00:03:51,950

line of code that actually gets the fuse the location API.



60

00:03:52,140 --> 00:03:58,170

I can just type in a location assignment operator and now I can get you to access I can refer to this



61

00:03:58,180 --> 00:04:03,090

fuse location provider IP or so just type in your fuse the location provider API and now we can call



62

00:04:03,090 --> 00:04:06,840

this method and this instance gets last location.



63

00:04:06,840 --> 00:04:07,300

Right.



64

00:04:07,500 --> 00:04:11,970

And as the argument we must pass the Google API client instance.



65

00:04:12,030 --> 00:04:13,780

So we already have that in a sense right.



66

00:04:13,780 --> 00:04:16,900

So just typing here Google API client instance semi-colon.



67

00:04:16,980 --> 00:04:21,420

So you know that we actually created this value but here in line number 23 inside our main activity



68

00:04:21,420 --> 00:04:24,090

class and the initialized this rally about here.



69

00:04:24,120 --> 00:04:27,680

So now we are we need to pass this value here.



70

00:04:27,720 --> 00:04:33,690

This will be the client here as the argument to the Smurfit So now it can actually give us the location



71

00:04:33,750 --> 00:04:35,770

if it is actually not null.



72

00:04:35,880 --> 00:04:37,990

So we need to actually check for that condition.



73

00:04:37,990 --> 00:04:40,690

So here it is called defensive programming.



74

00:04:40,710 --> 00:04:43,290

We must check for any conditions.



75

00:04:43,470 --> 00:04:44,860

Conditions may actually go wrong.



76

00:04:44,910 --> 00:04:48,010

OK the user may not be able to access the location.



77

00:04:48,030 --> 00:04:49,520

We must check for that condition.



78

00:04:49,530 --> 00:04:58,320

So I cant just create an if statement here I can say if location is not equal to non-HD OK that I open



79

00:04:58,620 --> 00:05:04,920

and close this if statement by using curly braces and open incredible is followed by a closing curly



80

00:05:04,920 --> 00:05:07,390

brace inside this statement.



81

00:05:07,620 --> 00:05:15,690

Now I am a hundred and fifty percent sure that this location here is not actually not because I am inside



82

00:05:15,690 --> 00:05:18,270

the curly braces of this statement right.



83

00:05:18,300 --> 00:05:24,100

So here I can say double here and the name of this variable is going to be letter.



84

00:05:24,130 --> 00:05:30,390

So I am actually creating a local variable of type double here latitudes assignment operator.



85

00:05:30,730 --> 00:05:37,420

And now because I have the location here this location actually holds the latitude and longitude coordinates.



86

00:05:37,420 --> 00:05:44,410

So here I can say location that latitude that gets latitude Senechal right and now I can say double



87

00:05:45,880 --> 00:05:46,750

longitude.



88

00:05:48,490 --> 00:05:55,520

Assignment operator location that gets longitude semicolon right.



89

00:05:55,690 --> 00:06:05,250

And now I can actually just type in here TXI the location that said text and insight Apprentice's here.



90

00:06:05,500 --> 00:06:07,710

I can just type in here.



91

00:06:07,830 --> 00:06:14,500

Actually latitude plus two coats and just put a comma here.



92

00:06:14,500 --> 00:06:17,220

Space plus longitude.



93

00:06:17,350 --> 00:06:23,880

So I want to actually outputs the latitude and longitude of the use user's location to the actually



94

00:06:24,010 --> 00:06:24,670

screen.



95

00:06:24,910 --> 00:06:30,940

OK so because we want to access the user's location it is necessary that you run your application on



96

00:06:30,940 --> 00:06:37,240

your actual Android device because the emulator does not have the capability to actually understand



97

00:06:37,240 --> 00:06:39,360

the user's location right.



98

00:06:39,460 --> 00:06:47,060

So here first let's also create an else statement for this if statement here.



99

00:06:47,200 --> 00:06:49,850

So here we are thinking that if the location is not equal to.



100

00:06:49,860 --> 00:06:50,470

All right.



101

00:06:50,560 --> 00:06:55,750

So what happens if the location is actually not in that case we can actually create an else statement



102

00:06:55,780 --> 00:06:58,780

and let the user know that the application.



103

00:06:58,840 --> 00:06:59,590

Would that be able.



104

00:06:59,620 --> 00:07:02,160

We would not be able to access the location now.



105

00:07:02,170 --> 00:07:11,510

So here I can say to the location that said text and instead of prentices I can say the app the app



106

00:07:12,940 --> 00:07:23,050

is not actually able to access the location the location.



107

00:07:23,230 --> 00:07:30,850

Now try again later try again later.



108

00:07:30,870 --> 00:07:38,070

So let me create a new line here so as you can see the idea I put this plus operator here is a concatenation



109

00:07:38,070 --> 00:07:41,070

operator in order to concatenate this value with this value.



110

00:07:41,070 --> 00:07:43,360

When I tried to actually create a new light.



111

00:07:43,370 --> 00:07:44,750

You're right.



112

00:07:44,790 --> 00:07:46,020

So that's it.



113

00:07:46,020 --> 00:07:51,660

So we need to actually also create some efforts it's we need to actually call the Smurfette from another



114

00:07:51,660 --> 00:07:53,450

location from other methods.



115

00:07:53,460 --> 00:07:58,170

So we just created this custom effect here and we are not calling it from other methods yet.



116

00:07:58,290 --> 00:07:59,940

So let's see how we can do that.
