00:00:00,240 --> 00:00:01,100

Hello everyone.



2

00:00:01,110 --> 00:00:07,800

So it is the story I want to tell you that because we want to access the user's location we want to



3

00:00:07,890 --> 00:00:11,040

we need to actually to first ask for the permission.



4

00:00:11,040 --> 00:00:16,140

So it's very important that first we must actually ask for the parent permission because we want to



5

00:00:16,140 --> 00:00:21,300

access the use that it's location and it is actually called a dangerous permissions so we must ask.



6

00:00:21,750 --> 00:00:26,660

First of all we need to actually put that permission inside the manifest file so that I should add that



7

00:00:26,660 --> 00:00:30,510

up just click on View and then tool windows and that we can project.



8

00:00:30,630 --> 00:00:36,520

So as you can see the shortcut for the match is comment 1 if you are using a Windows machine the shortcut



9

00:00:36,520 --> 00:00:37,880

should be must be different.



10

00:00:37,890 --> 00:00:40,420

So I think it is actually control one.



11

00:00:40,590 --> 00:00:41,510

So just click on it.



12

00:00:43,010 --> 00:00:49,420

So here let's actually open the app folder here and then let's double click on this manifests here.



13

00:00:49,580 --> 00:00:54,550

If you don't have this manifest file here you just to open this folder and it is actually the object



14

00:00:54,640 --> 00:00:55,810

manifesto and fight.



15

00:00:56,060 --> 00:00:59,690

So let me double click on this tab and write manifested XML.



16

00:00:59,900 --> 00:01:06,620

So inside this android manifested exemplified here after the ending tag of this manifest and before



17

00:01:06,620 --> 00:01:07,260

the ending.



18

00:01:07,310 --> 00:01:10,160

Or should it be for this application.



19

00:01:10,490 --> 00:01:16,340

I would actually put these permissions here which is open attack and just type in here use is permission



20

00:01:17,300 --> 00:01:21,650

and the name is going to be course location and access course location.



21

00:01:21,650 --> 00:01:23,140

So what is this permission.



22

00:01:23,300 --> 00:01:29,300

It is actually that the permission that is going to give us the location actually the approximate location



23

00:01:29,360 --> 00:01:31,130

of the users device.



24

00:01:31,200 --> 00:01:31,640

OK.



25

00:01:31,790 --> 00:01:35,730

So the course of course location is going to give us the approximate location.



26

00:01:35,750 --> 00:01:38,590

We have another location called Falling location.



27

00:01:38,600 --> 00:01:43,800

So it is the final location is a little bit more actually exact it is more precise.



28

00:01:44,120 --> 00:01:49,370

But the problem with accessing a final location is that it going to actually eat more battery.



29

00:01:49,370 --> 00:01:55,020

So we are going to stick with this one access course location is actually enough for this application.



30

00:01:55,040 --> 00:01:56,750

It's going to just give us the approximate location.



31

00:01:56,750 --> 00:02:02,960

So let's put up a slash and the end in type in order to actually close the stack here.



32

00:02:02,960 --> 00:02:03,970

So that's it.



33

00:02:04,040 --> 00:02:07,030

And now we need to actually at the meditator.



34

00:02:07,330 --> 00:02:09,830

OK so let's see how we can do that.



35

00:02:09,830 --> 00:02:15,920

So now you may ask that so why we have to add them to the top because we need to tell the Andray manifest



36

00:02:16,190 --> 00:02:18,950

that we are going to use the Google Play services.



37

00:02:18,950 --> 00:02:21,250

So it is very important that we at the Met at 8am.



38

00:02:21,380 --> 00:02:25,510

So after you can see this application Typepad here right it is actually their starting.



39

00:02:25,730 --> 00:02:27,740

And it is the ending tag here.



40

00:02:27,740 --> 00:02:28,350

Right.



41

00:02:28,370 --> 00:02:32,600

So after this starting tag and before these activities here.



42

00:02:32,770 --> 00:02:33,050

OK.



43

00:02:33,050 --> 00:02:34,460

I created some space.



44

00:02:34,460 --> 00:02:37,400

Here it is the place actually to add the metadata.



45

00:02:37,400 --> 00:02:40,180

So just open it and just typing here Mr. data.



46

00:02:40,670 --> 00:02:45,590

And then here let's actually create a new line here let me create on your line and just type in here



47

00:02:45,980 --> 00:02:49,300

actually name and inside the quotes here.



48

00:02:49,370 --> 00:02:57,280

Just type in here come that Google dot Android dot GM s dot version.



49

00:02:57,800 --> 00:02:59,270

OK that version.



50

00:02:59,720 --> 00:03:03,790

And then here as you can see we added this name here right.



51

00:03:03,800 --> 00:03:09,260

You need to actually add another value here and it is actually called value.



52

00:03:09,290 --> 00:03:15,260

So just type in here value and here this is value right so inside the quotes instead of course just



53

00:03:15,260 --> 00:03:19,270

typing here at sign integer and just typing here.



54

00:03:19,270 --> 00:03:21,180

Google Play services version.



55

00:03:21,190 --> 00:03:26,560

So the autocomplete feature of Android studio is going to help you to choose this one so just pleasant



56

00:03:27,050 --> 00:03:32,770

person on your keyboard and in order to end this tablet you're going to self-closing this like right.



57

00:03:32,890 --> 00:03:39,020

I just need to put on slash here and here you can see that the Android to do you put this into here



58

00:03:39,040 --> 00:03:40,260

for me automatically.



59

00:03:40,330 --> 00:03:40,810

Right.



60

00:03:41,020 --> 00:03:42,960

So this is our metadata.



61

00:03:43,180 --> 00:03:49,630

And here I want to specify that this application is going to be used only in portrait mode not in landscape



62

00:03:49,630 --> 00:03:52,470

mode but only in portrait mode so how we can do that.



63

00:03:52,570 --> 00:03:55,940

So here you can see it is actually activity tach right.



64

00:03:55,960 --> 00:03:57,800

This is actually distorting Tadg.



65

00:03:57,940 --> 00:04:00,900

So here it says android named main activity.



66

00:04:01,000 --> 00:04:08,960

Let's actually create our space here and here just type the screen orientation screen orientation and



67

00:04:09,520 --> 00:04:12,380

just choose portrait's right.



68

00:04:12,380 --> 00:04:18,060

So now here we are telling the activity that this activity here main activity is going to be only used



69

00:04:18,380 --> 00:04:21,050

in portraits mode not in landscape mode.



70

00:04:21,110 --> 00:04:22,220

OK.



71

00:04:22,220 --> 00:04:23,370

So that's it.



72

00:04:23,720 --> 00:04:28,400

And now we actually added all the codes that we needed for now.



73

00:04:28,460 --> 00:04:32,820

OK so far we've added all the cards that we needed here to these and manifest why.



74

00:04:32,870 --> 00:04:38,380

So now it's time to go to the main activity class and here you can see these fits right.



75

00:04:38,390 --> 00:04:39,000

Right.



76

00:04:39,080 --> 00:04:44,520

So now I'm going to actually create a new method inside these main activity and inside this man I can



77

00:04:44,550 --> 00:04:50,370

declasse actually so at the top of the bottom of the fight after the ending curly brace of this on can



78

00:04:50,380 --> 00:04:50,990

action fake.



79

00:04:51,020 --> 00:04:56,540

I'm going to create m if I want to create a comment here that says I should custom if it's like a custom



80

00:04:57,120 --> 00:04:57,610

methods.



81

00:04:57,770 --> 00:05:01,120

So the custom effects are the methods that I actually added myself.



82

00:05:01,280 --> 00:05:01,740

OK.



83

00:05:01,970 --> 00:05:05,160

So let's put these Misfit's here below this comment.



84

00:05:05,220 --> 00:05:10,760

So because we are going to use this method only inside this main activity class we can actually declare



85

00:05:10,800 --> 00:05:12,620

RMF as private for now.



86

00:05:12,710 --> 00:05:13,160

OK.



87

00:05:13,220 --> 00:05:16,040

Later we may want to actually to change this access modifier.



88

00:05:16,040 --> 00:05:22,850

But for now I just want to use this method inside this main activity class so private and return type



89

00:05:22,850 --> 00:05:29,780

of this method is going to be void and the name of this Smurfette is going to be actually show the user



90

00:05:31,480 --> 00:05:38,350

location write and put up that apprentices this movie is not going to accept any prime interest and



91

00:05:38,350 --> 00:05:41,120

just open and close the Smurfit by using these curly braces.



92

00:05:41,140 --> 00:05:49,690

So inside this method first we need to actually ask the user in order to give us the permission in order



93

00:05:49,690 --> 00:05:51,740

to access the location.



94

00:05:51,760 --> 00:05:52,140

OK.



95

00:05:52,240 --> 00:05:54,300

So it is called runtime permission.



96

00:05:54,310 --> 00:05:58,690

We must ask the user because it is actually necessary.



97

00:05:58,690 --> 00:06:00,740

It is called A Dangerous permission.



98

00:06:00,850 --> 00:06:06,730

In Android to access the user's location so the user must be actually aware of that permission.



99

00:06:06,730 --> 00:06:09,240

So it is called a runtime permission.



100

00:06:09,250 --> 00:06:10,650

So let's see how we can do that.



101

00:06:10,660 --> 00:06:15,670

First let's create a variable of type in teacher and the name of this variable is going to be permission



102

00:06:15,670 --> 00:06:24,220

check permission check and put an assignment operator here and just type in here context compacts that



103

00:06:24,520 --> 00:06:26,560

check self permission.



104

00:06:27,540 --> 00:06:31,180

First if it actually accepts two arguments the first one is the context.



105

00:06:31,180 --> 00:06:35,900

So the context is main activity right because the main activity is going to actually access the location.



106

00:06:35,910 --> 00:06:42,500

So main activity that this is the context the comma the second argument is going to be the actual permission.



107

00:06:42,540 --> 00:06:47,970

So because we want to access the user's location the users approximate location actually I'm going to



108

00:06:48,150 --> 00:06:51,550

just type in here and manifest that permission.



109

00:06:51,840 --> 00:06:53,240

That just they've been here.



110

00:06:53,250 --> 00:06:55,940

Course we've chapiter c course location.



111

00:06:56,160 --> 00:07:00,420

So it's going to put the actual name here automatically for us and then put a semicolon at the end of



112

00:07:00,420 --> 00:07:01,200

this statement.



113

00:07:01,410 --> 00:07:04,910

So let me ask you to create a new line here so that you can see these values.



114

00:07:04,920 --> 00:07:09,390

So as you can see if we create that are valuable if that is your permission check and we assign this



115

00:07:09,390 --> 00:07:13,520

value to this valuable context compact that checks of permission.



116

00:07:13,740 --> 00:07:15,650

And as the arguments first.



117

00:07:15,660 --> 00:07:18,060

We need to pass the the context.



118

00:07:18,240 --> 00:07:20,740

And the second argument is going to be the actual location.



119

00:07:20,760 --> 00:07:26,070

So this code here is going to actually return a value of that material and it's and it is going to be



120

00:07:26,070 --> 00:07:27,840

assigned to this body of it.



121

00:07:28,020 --> 00:07:31,600

So now I can create an if statement right.



122

00:07:31,620 --> 00:07:41,450

I can actually say if permission check is equal to package manager that permission granted.



123

00:07:41,450 --> 00:07:47,770

So as you can see I need to put a capital P in order to actually see the autocomplete feature ID or



124

00:07:47,770 --> 00:07:49,910

to complete the options here.



125

00:07:50,060 --> 00:07:51,750

So it was permission granted.



126

00:07:51,770 --> 00:07:57,650

So this means that if their permission to value is equal to the Permission granted here this means that



127

00:07:57,710 --> 00:08:03,260

the user has actually gave us their permission to access the location right.



128

00:08:03,260 --> 00:08:07,610

In that case we can actually open and close this method by using the curly braces.



129

00:08:07,790 --> 00:08:09,980

So let's create an else statement here.



130

00:08:10,040 --> 00:08:16,520

LS So else means what else means that this expression he had evaluated to false.



131

00:08:16,550 --> 00:08:19,690

So now it is going to execute this else it's.



132

00:08:19,850 --> 00:08:26,330

So in that case if this condition is false and the user actually denied to access the location the right



133

00:08:26,480 --> 00:08:30,050

to access the location in that case you are going to execute this statement.



134

00:08:30,050 --> 00:08:36,890

So here I can't just CTX the location that a said text and I can just put two codes here and here I



135

00:08:36,890 --> 00:08:46,040

can say this app is not allowed to access the location.



136

00:08:46,170 --> 00:08:46,970

Right.



137

00:08:46,980 --> 00:08:49,970

So this is the else statement and that is actually to go inside this.



138

00:08:49,990 --> 00:08:54,840

And so this means that the user has actually gave us that the actually the permission so we can actually



139

00:08:54,840 --> 00:08:55,900

put the quotes here.



140

00:08:56,040 --> 00:08:57,380

But inside this Elsa's statement.



141

00:08:57,390 --> 00:08:59,790

Let's add another quote here it is.



142

00:08:59,790 --> 00:09:04,130

This means that the user is not actually doesn't allow us to access the location right.



143

00:09:04,140 --> 00:09:09,990

So we can actually ask the user we can actually create our requests here in order to ask the user to



144

00:09:10,020 --> 00:09:14,970

give this application the permission to access the location.



145

00:09:14,970 --> 00:09:16,680

So let's see how we can do that.



146

00:09:16,680 --> 00:09:20,480

So I'm going to paste this line of code here and then I'm going to explain to you what's going on here.



147

00:09:20,490 --> 00:09:21,510

Exactly.



148

00:09:21,510 --> 00:09:23,820

So as you can see I actually pasted this line of code here.



149

00:09:23,820 --> 00:09:27,920

It says activity compact that request permissions.



150

00:09:28,080 --> 00:09:31,160

So it is going to actually actually create a request.



151

00:09:31,160 --> 00:09:33,210

I was going to ask the user to access the location.



152

00:09:33,210 --> 00:09:36,350

First we need to pass the context main activity that this come up.



153

00:09:36,510 --> 00:09:39,180

And the second argument is this one new stream.



154

00:09:39,180 --> 00:09:42,590

So here it is going to create the paramecia right streamed.



155

00:09:42,660 --> 00:09:46,040

It is actually an array right new An at a upstreams.



156

00:09:46,440 --> 00:09:48,950

And as the first value of this.



157

00:09:48,990 --> 00:09:54,090

Here we are going to pass this value inside the curly braces manifest that permission that access course



158

00:09:54,090 --> 00:10:01,090

location come up here and it is actually to devalue number one here so what is this value let me actually



159

00:10:01,090 --> 00:10:04,270

just again type this out here again.



160

00:10:04,270 --> 00:10:11,710

So the first value is activity Compaq's write activity compact that request permissions.



161

00:10:11,710 --> 00:10:14,450

So let me tell you this is actually the request code.



162

00:10:14,500 --> 00:10:16,520

Ok the first argument is the request code.



163

00:10:16,660 --> 00:10:20,920

So here I just this is actually just a simple request right.



164

00:10:20,950 --> 00:10:22,040

So I just passed the value.



165

00:10:22,040 --> 00:10:27,310

Number one if you want to you can actually change it to any other values or you can just create a constant



166

00:10:27,310 --> 00:10:32,010

for this value but it is just a simple request or just past the value number one.



167

00:10:32,140 --> 00:10:32,700

OK.



168

00:10:33,010 --> 00:10:38,020

So make sure that it is actually a unique value that you are not using inside your application.



169

00:10:38,020 --> 00:10:41,140

So number one is not use the inside for that application.



170

00:10:41,140 --> 00:10:43,390

So I just pass on to that number one here.



171

00:10:43,420 --> 00:10:47,630

So now we can go inside this statement.
