00:00:00,230 --> 00:00:01,070

Hi everyone.



2

00:00:01,140 --> 00:00:04,470

So now you're actually inside these mass activity class.



3

00:00:04,470 --> 00:00:08,930

So in this matter activity class we are going to actually declare a variable.



4

00:00:09,210 --> 00:00:11,670

So is this class distopian private.



5

00:00:12,030 --> 00:00:14,250

And at the top of this idea is strange.



6

00:00:14,520 --> 00:00:20,290

And the name of this variable is received received country right.



7

00:00:20,310 --> 00:00:21,140

Semicolon.



8

00:00:21,210 --> 00:00:25,670

So we are going to actually receive or get the country from the main activity class.



9

00:00:25,670 --> 00:00:26,120

Right.



10

00:00:26,400 --> 00:00:34,320

So now let's go to this other uncreate Smurfette here and after these lines of code here I'm going to



11

00:00:34,320 --> 00:00:36,680

actually put some codes here.



12

00:00:36,900 --> 00:00:41,680

But before that let's take a look at these codes here you can see that.



13

00:00:41,840 --> 00:00:42,570

Take a look at this.



14

00:00:42,570 --> 00:00:48,660

This comment here it says obtain the support map fragment and gets notified when the map is ready to



15

00:00:48,660 --> 00:00:49,230

be used.



16

00:00:49,290 --> 00:00:49,680

OK.



17

00:00:49,800 --> 00:00:55,110

So first it's going to actually get the support of a fragment here and it's going to find a fragment



18

00:00:55,200 --> 00:01:01,200

or that ID that map and it's going to actually call this if it gets map a seen it on this map fragment



19

00:01:01,200 --> 00:01:01,650

here.



20

00:01:01,650 --> 00:01:02,260

Right.



21

00:01:02,340 --> 00:01:08,040

So it is going to actually get them support my fragment and it's going to actually get notified when



22

00:01:08,040 --> 00:01:09,240

that map is ready.



23

00:01:09,240 --> 00:01:15,060

So before the map is ready all you want to get the country from the Minuteman activity you want to get



24

00:01:15,060 --> 00:01:19,410

to use the word that value that is actually passed to that intent.



25

00:01:19,410 --> 00:01:22,440

I want to get that value here before the map is ready.



26

00:01:22,680 --> 00:01:29,070

So after this line of code here that colors sits content to view it I can actually put my own logic



27

00:01:29,070 --> 00:01:29,700

here.



28

00:01:30,090 --> 00:01:31,180

Right.



29

00:01:31,220 --> 00:01:37,760

We need to access the intent that is actually used to send the data to this class.



30

00:01:38,070 --> 00:01:43,350

The intent that is used to transition to this class to this activity.



31

00:01:43,680 --> 00:01:52,730

So just in here intent and here know that the intent that is used to transition to this activity is



32

00:01:52,730 --> 00:01:53,710

the main activity.



33

00:01:53,810 --> 00:02:03,950

So I can just say main activity intent main activity intent assignment operator and I can just call



34

00:02:03,950 --> 00:02:07,280

this if it gets into that semicolon.



35

00:02:07,280 --> 00:02:13,010

That's it by just calling to decide if a good intent on an instance of type maps activities or not is



36

00:02:13,010 --> 00:02:16,520

that it is actually the this that's intent OK.



37

00:02:16,550 --> 00:02:18,260

Does that good intent.



38

00:02:18,290 --> 00:02:25,310

So by calling it an instance of type maps activity here we get the original intent that is used to transition



39

00:02:25,310 --> 00:02:31,570

to this activity here and we are assigning to these valuable here main activity intent.



40

00:02:31,580 --> 00:02:37,640

So now it's time to initialize or valuable that be declared in line number to anyone inside these maps



41

00:02:37,640 --> 00:02:38,660

activity class.



42

00:02:38,660 --> 00:02:42,780

So agency received country assignment operator.



43

00:02:42,980 --> 00:02:51,080

So now I can refer to this intent main activity intent that gets strange extra get something extra.



44

00:02:51,080 --> 00:02:56,630

And here I just need to pass the key in order to access the value that is passed to that intent.



45

00:02:56,810 --> 00:02:57,640

OK.



46

00:02:57,830 --> 00:03:02,240

Let's go back to this man with the glass to this maps activity engine here but just passing the key



47

00:03:02,240 --> 00:03:02,730

here.



48

00:03:02,830 --> 00:03:04,080

Are going to pass the value.



49

00:03:04,100 --> 00:03:11,090

So let's go back to my maps activity class and here we know that the key is let's refer to this country



50

00:03:11,090 --> 00:03:15,480

data source class that contradicts the semicolon.



51

00:03:15,590 --> 00:03:20,930

That's it by just referring to this key I can access the value and the value is going to be assigned



52

00:03:20,930 --> 00:03:23,120

to the received country valuable.



53

00:03:23,330 --> 00:03:25,730

And we know that the value is of type string.



54

00:03:25,730 --> 00:03:27,070

This is really important.



55

00:03:27,110 --> 00:03:28,980

So here there is a problem.



56

00:03:29,210 --> 00:03:37,660

What happens if they have value that is passed to this intent to this activity is actually not OK.



57

00:03:37,910 --> 00:03:42,380

So in that case we are going to actually have some problems.



58

00:03:42,400 --> 00:03:47,150

So in order to solve this problem after this line of code let's create an if statement and let's say



59

00:03:47,150 --> 00:03:54,970

if received country is equal to null then let's open and close this if statement by using these curly



60

00:03:54,980 --> 00:03:55,660

braces.



61

00:03:55,670 --> 00:04:00,780

In that case we are going to say that the received country is going to be there.



62

00:04:00,840 --> 00:04:08,270

Let's refer to this country data source class that default country name semi-hollow So the default country



63

00:04:08,270 --> 00:04:14,320

name is going to be assigned to the received country OK if the rest of the country is not.



64

00:04:14,660 --> 00:04:21,410

So now let's go through this on the map Reddam effort here and here you can see that you are accessing



65

00:04:21,410 --> 00:04:24,770

the Iceland by using these latitude and longitude.



66

00:04:24,890 --> 00:04:27,500

You create you're creating multiple options circle options.



67

00:04:27,500 --> 00:04:35,980

So we don't need to use these actually the calls here let's just delete all these codes here except



68

00:04:35,990 --> 00:04:39,730

this initialization of this map variable Google map.



69

00:04:40,040 --> 00:04:44,120

After this line of code now we're going to put some new logic's here.



70

00:04:44,300 --> 00:04:51,650

So here if you are going to use the geocoding capability and what is to according to geocoding is used



71

00:04:51,710 --> 00:04:56,830

to actually convert of value for example Canada or Canada.



72

00:04:57,040 --> 00:05:03,830

You are going to use a digital coding capability in order to access the latitude and longitude of Canada



73

00:05:03,870 --> 00:05:05,790

into the map.



74

00:05:05,990 --> 00:05:07,510

So that is called geocoding.



75

00:05:07,520 --> 00:05:16,840

But for now let's just create some for example valuables in order to hold the default latitude and longitude



76

00:05:16,850 --> 00:05:19,940

if they received country is actually not.



77

00:05:20,120 --> 00:05:22,760

So let's see what you're going to do next here.



78

00:05:22,760 --> 00:05:32,420

Let's create a variable of type double and the name of this variable is country latitude assignment



79

00:05:32,420 --> 00:05:39,920

operator and initially I'm going to assign the default latitude of the default country to this variable.



80

00:05:39,920 --> 00:05:45,620

So if you go to this country data source class you can see that the default country is Canada.



81

00:05:45,620 --> 00:05:46,380

Right.



82

00:05:46,850 --> 00:05:53,860

And here we specified the latitude and longitude of Canada here as the default country latitude and



83

00:05:53,860 --> 00:05:55,390

default country longitude.



84

00:05:55,430 --> 00:05:58,360

So let's go to these maps activity cles.



85

00:05:58,730 --> 00:06:00,360

So here I can defer.



86

00:06:00,410 --> 00:06:04,790

So initially I'm going to initialize this very well and ensure that I'm going to assign the default



87

00:06:04,790 --> 00:06:08,500

latitude the default country that is actually to this rally.



88

00:06:08,780 --> 00:06:16,350

So when I refer to this country that are sort of class that default country latitude semicolon.



89

00:06:16,760 --> 00:06:24,740

Let's create another variable of type double country longitude assignment operator and just refer to



90

00:06:24,740 --> 00:06:33,280

this country data source class country data source as it is with capital C country data source.



91

00:06:33,280 --> 00:06:37,380

Otherwise the autocomplete feature of Andrew sudi isn't going to help us.



92

00:06:37,480 --> 00:06:44,560

So we must use the capital C in order to access the country that source class that default country longitude



93

00:06:44,730 --> 00:06:45,670

semicolon.



94

00:06:45,970 --> 00:06:52,900

So here let's create a variable of type country data source so I can say country data source and the



95

00:06:52,900 --> 00:06:55,650

name is country data source assignment operator.



96

00:06:55,900 --> 00:06:59,280

So let's go to our main activity class and here let me scroll to the top.



97

00:06:59,330 --> 00:07:05,920

You can see that I created a static variable of type country datasource inside this class and inside



98

00:07:05,920 --> 00:07:11,380

the uncreate in fact I initialized this variable by using this hash table by the above right by using



99

00:07:11,380 --> 00:07:16,780

these countries and messages which is a hash table and I passed this hash table valuable to the constructor



100

00:07:17,170 --> 00:07:22,720

of this class so it is going to construct a new instance of type data source class and it's going to



101

00:07:22,720 --> 00:07:25,330

assign to this valuable country data source.



102

00:07:25,390 --> 00:07:32,290

So we already specified by the U.S. and Canada France Brazil United States Japan.



103

00:07:32,650 --> 00:07:37,120

So we can actually use this instance that we created in say this class.



104

00:07:37,120 --> 00:07:38,550

Let's go back to my maps activity.



105

00:07:38,540 --> 00:07:42,620

So first let me show you that it is actually a static variable.



106

00:07:42,670 --> 00:07:46,350

It is a class variable by just referring to the main activity class.



107

00:07:46,370 --> 00:07:52,650

I can direct the access this country data source instance without creating a new instance of the main



108

00:07:52,660 --> 00:07:53,380

activity.



109

00:07:53,680 --> 00:08:00,610

So let's go back to my maps activity class and I can just refer to this main activity main activity



110

00:08:02,850 --> 00:08:06,620

that country data source semicon and that's it.



111

00:08:06,720 --> 00:08:12,210

And now we initialized this roudy table by just accessing the country data source for instance that



112

00:08:12,210 --> 00:08:14,380

we have inside this main activity class.



113

00:08:14,730 --> 00:08:20,690

So here let's actually create a variable of type stream.



114

00:08:20,700 --> 00:08:28,320

So just in here is strange and the name of this valuable it's going to be country message assignment



115

00:08:28,320 --> 00:08:37,650

operator and now I'm going to refer to this country data source country data source that gets the info



116

00:08:37,680 --> 00:08:40,080

of the country get the info of the country.



117

00:08:40,080 --> 00:08:46,830

So here I just need to pass the country in order to get the value or the message or the info of that



118

00:08:46,830 --> 00:08:47,430

country.



119

00:08:47,550 --> 00:08:53,280

So if I go to this main activity class here you can see that V is specified for for example the country



120

00:08:53,310 --> 00:08:57,750

as the key and the message or the info as the value.



121

00:08:57,780 --> 00:09:02,800

So let's go back to country data source class here at the bottom of the file we created.



122

00:09:02,810 --> 00:09:03,600

I'm afraid you're right.



123

00:09:03,600 --> 00:09:08,910

Get the info out of the country and hear this if it accepts an argument of type string.



124

00:09:09,120 --> 00:09:13,700

So here we are returning this value.



125

00:09:13,770 --> 00:09:17,170

You are referring to this hash table value but that gets country.



126

00:09:17,220 --> 00:09:22,480

So if I pass the country the key you're going to get the value right.



127

00:09:22,520 --> 00:09:23,400

Good country.



128

00:09:23,400 --> 00:09:29,080

This means that past that key an access the value of this has been actually valuable.



129

00:09:29,130 --> 00:09:32,400

So let's go back to main maps activity class and here.



130

00:09:32,430 --> 00:09:37,820

When I say get the info of the country here we just need to pass the key which is going to be the country.



131

00:09:37,820 --> 00:09:43,840

So we have already actually a variable that is called received country.



132

00:09:43,860 --> 00:09:51,320

We actually get this value from the main activity and we are passing this as the key to this effort



133

00:09:51,690 --> 00:09:57,990

and it's going to give us the message devalue and we're going to assign that value to this country message.



134

00:09:57,990 --> 00:09:58,610

Right.



135

00:09:59,040 --> 00:10:03,610

So now it's time to start the geocoding process.



136

00:10:03,660 --> 00:10:07,220

So first of all we need to create an instance of type geocoder.



137

00:10:07,410 --> 00:10:14,140

So just step in here geocoder and the name is going to be geocoder assignment operator new geocoder.



138

00:10:14,270 --> 00:10:14,930

Right.



139

00:10:14,930 --> 00:10:20,720

So here we just need to pass the context which is going to be maps activity that this maps activity



140

00:10:20,750 --> 00:10:22,470

that this semicolon.



141

00:10:22,670 --> 00:10:29,220

So first let me tell you that at any point in the accordion process something can go wrong.



142

00:10:29,330 --> 00:10:29,750

OK.



143

00:10:29,840 --> 00:10:38,090

So we must put our logic into the try catch block in order to capture the exceptions that we may have



144

00:10:38,930 --> 00:10:43,210

in their geocoding process so let's just open here to try.



145

00:10:43,220 --> 00:10:48,920

So we have this triple check and after the I think the price of this Troy block I can't say catch on



146

00:10:49,030 --> 00:10:49,520

here.



147

00:10:49,550 --> 00:10:51,670

Let's use the exception.



148

00:10:51,730 --> 00:10:56,420

I e this open and closed this catch by using curly braces.



149

00:10:57,740 --> 00:11:04,610

So not is that this Iowa exception is a subclass of exception and we can use it in order to actually



150

00:11:04,620 --> 00:11:11,690

capture capture the errors and the exceptions that that may occur inside our project.



151

00:11:11,690 --> 00:11:14,080

So let's go inside is Charlie Black here.



152

00:11:14,090 --> 00:11:20,240

So here first we need to access the address of the country as a string value so that we can actually



153

00:11:20,240 --> 00:11:25,730

start geocoding by using that address and we can convert that string value to the latitude and longitude



154

00:11:25,730 --> 00:11:27,440

of that country name.



155

00:11:27,620 --> 00:11:33,380

So first I need to create a value of type strange and the name of this variable is going to be country



156

00:11:33,620 --> 00:11:37,370

address assignment operator.



157

00:11:37,550 --> 00:11:46,380

And here let's referred to two up valuable that we created inside our class called received country.



158

00:11:46,400 --> 00:11:53,780

So not is that this valuable this value is actually received from the main activity by using the speech



159

00:11:53,780 --> 00:11:54,960

recognition framework.



160

00:11:54,980 --> 00:11:56,380

But using the voice intent.



161

00:11:56,630 --> 00:11:58,480

So that's why it is called received country.



162

00:11:58,490 --> 00:12:03,310

So here it is going to be the address we assign it to this valuable country address.



163

00:12:03,470 --> 00:12:12,320

After this line of code let's create a list of country addresses so I can say list at inside the angle



164

00:12:12,320 --> 00:12:17,160

brackets we need to specify the data type of the objects that we're going to have inside this list.



165

00:12:17,330 --> 00:12:19,850

So it is going to be of type address.



166

00:12:19,940 --> 00:12:25,580

So we already have a class called address in Android that location package.



167

00:12:25,820 --> 00:12:29,190

Let me show you the and the documentation first.



168

00:12:29,210 --> 00:12:32,300

So here it is the android documentation inside the search bar.



169

00:12:32,300 --> 00:12:34,190

Let's search for address.



170

00:12:34,190 --> 00:12:38,780

So here you can see and with that location that address let's click on it and here you can see that



171

00:12:38,780 --> 00:12:44,700

it is actually a class that extends the object class and implements the parsable interface.



172

00:12:44,930 --> 00:12:51,860

So take a look at this description it says a class representing an address or a set of strings describing



173

00:12:51,890 --> 00:12:57,970

a location the address format is a simplified version of X..



174

00:12:58,220 --> 00:13:04,040

So don't about these values here for not just take a look at this summit here and this address locale



175

00:13:04,040 --> 00:13:11,720

constructs and and address object object set to the given locale and with all other fields initialized



176

00:13:11,780 --> 00:13:13,370

to not or false.



177

00:13:13,460 --> 00:13:18,050

We have this clear latitude removes any latitude associated with this address.



178

00:13:18,080 --> 00:13:24,130

You can actually take take a look at this or if it's here for example get at me an area get address



179

00:13:24,140 --> 00:13:30,280

line we can get the country name get through us and all these benefits here.



180

00:13:30,320 --> 00:13:31,050

Right.



181

00:13:31,070 --> 00:13:38,330

So don't worry just let's go back to android studio and now that we have this address class here let's



182

00:13:38,330 --> 00:13:45,800

name this valuable as country atlases country addresses assignment operator.



183

00:13:45,920 --> 00:13:55,190

So let's leave first to the still code for instance geocoder that gets from location name here so you



184

00:13:55,190 --> 00:13:58,270

can see that we have two versions of this for it through this movie.



185

00:13:58,280 --> 00:14:00,710

Again we have two versions of this.



186

00:14:00,710 --> 00:14:05,480

The first one accepts through argument and the second version accepts some more arguments for example



187

00:14:05,810 --> 00:14:13,160

and I accept that the name the max resolves the lower left latitude longitude with the upper right attitude



188

00:14:13,190 --> 00:14:14,990

and the upper right longitude.



189

00:14:14,990 --> 00:14:20,780

So if you're going to use the first version that actually only accepts two arguments location name and



190

00:14:20,780 --> 00:14:22,220

the max resorts.



191

00:14:22,280 --> 00:14:26,960

So we know what is the location and the location name is the country atomists just referred to this



192

00:14:27,440 --> 00:14:29,450

instance to this valuable country address.



193

00:14:29,450 --> 00:14:30,000

Come on.



194

00:14:30,170 --> 00:14:33,130

And the message is always going to be 10 semicolon.



195

00:14:33,380 --> 00:14:38,980

So it's going to give us 10 results maximum by using this country address.



196

00:14:39,020 --> 00:14:48,980

So here let's create an if statement so if country addresses country addresses is not equal to null



197

00:14:49,450 --> 00:14:50,050

here.



198

00:14:50,090 --> 00:14:56,630

We need to actually check for this condition here and only in that case we can assign some real values



199

00:14:57,020 --> 00:15:00,070

to these valuable country and country longitude.



200

00:15:00,290 --> 00:15:08,120

So instead this if statement I can refer to this country land latitude country latitude assignment operator



201

00:15:08,420 --> 00:15:15,080

so insight is least we have values of plate address right country addresses.



202

00:15:15,350 --> 00:15:19,490

So we said that we are going to have 10 maximum results.



203

00:15:19,490 --> 00:15:25,760

So let me tell you that the first result is going to be that the actually the precise one the most precise



204

00:15:26,030 --> 00:15:29,490

address that we can get from this list here.



205

00:15:29,510 --> 00:15:34,400

So I can refer to this country address's country addresses.



206

00:15:34,400 --> 00:15:41,540

So in order to access the first value that we have in say the least I need to call this method get and



207

00:15:41,540 --> 00:15:46,480

here I just need to pass the index which is going to be zero that gets latitude.



208

00:15:46,760 --> 00:15:52,400

So here we are calling to get latitude Meffert on the first object that we have in say the least which



209

00:15:52,400 --> 00:15:56,940

is if they address it right you are calling this method on this object that you have inside this list



210

00:15:57,200 --> 00:15:58,580

and it is the first object.



211

00:15:58,580 --> 00:16:03,740

And I told you that the first one the first object that we have in say this this is going to be the



212

00:16:03,740 --> 00:16:05,170

precise spot.



213

00:16:05,210 --> 00:16:08,630

So actually the most precise one not the precise one.



214

00:16:08,630 --> 00:16:15,680

So now let's put a semicolon at the end of our statement and let's refer to our country a lot longitude



215

00:16:15,880 --> 00:16:19,050

variable country longitude.



216

00:16:19,160 --> 00:16:24,800

So here we created this rally about in line number six the inside are on my ready Meffert assignment



217

00:16:24,800 --> 00:16:25,800

operator.



218

00:16:25,820 --> 00:16:35,670

So again let's refer to this country address's list that gets 0 that gets longitude semi-colon.



219

00:16:35,870 --> 00:16:40,630

So now what happens if the country addresses is actually not.



220

00:16:40,730 --> 00:16:42,550

We need to check for that condition too.



221

00:16:42,650 --> 00:16:48,560

So after this if if statement after the end in Kerley price of this statement let's create an else statement



222

00:16:48,650 --> 00:16:49,750

else here.



223

00:16:49,760 --> 00:16:58,450

We are going to say received country is going to be contrie datasource that default constraining semicolon.



224

00:16:58,760 --> 00:17:04,490

So if the country adolescent's is actually not we we don't have any country here we don't have any real



225

00:17:04,490 --> 00:17:05,020

country.



226

00:17:05,030 --> 00:17:09,920

So if you are going to specify the default country that is specified inside this class country at source



227

00:17:10,340 --> 00:17:15,820

as the country that we have here inside is received act received country rowdier.



228

00:17:15,930 --> 00:17:23,750

OK so now we also have this church block so that you know that this cataplexy is created to catch the



229

00:17:23,750 --> 00:17:27,620

exceptions that may occur in a a joke boarding process.



230

00:17:27,620 --> 00:17:30,120

So look at this line of thought here in line number 70.



231

00:17:30,380 --> 00:17:35,460

We are calling this method to get from location name on this geocoder instance.



232

00:17:35,510 --> 00:17:40,100

So it's going to start geocoding he is going to start the recording process.



233

00:17:40,100 --> 00:17:43,150

So some teens at some point can go wrong.



234

00:17:43,240 --> 00:17:43,830

OK.



235

00:17:43,850 --> 00:17:46,880

So in that case you're going to catch that error.



236

00:17:46,880 --> 00:17:55,520

So in this catch block we're going to say received country assignment operator country datasource that



237

00:17:55,760 --> 00:17:56,760

default country name.



238

00:17:56,780 --> 00:18:03,560

So if anything goes wrong in the recording process are going to specify the default country name as



239

00:18:03,560 --> 00:18:04,850

the received country.



240

00:18:04,850 --> 00:18:07,990

Here we are going to assign this value to the rest of the country.



241

00:18:08,060 --> 00:18:08,500

Right.



242

00:18:08,540 --> 00:18:14,610

So now after this catch block and after the ending curly brace of this catch block and before the end



243

00:18:14,630 --> 00:18:21,590

in place of this method of this on my Prady method here let's put some more logic here.



244

00:18:21,590 --> 00:18:27,200

So first let me tell you that now that we actually that we are actually using these data that we are



245

00:18:27,410 --> 00:18:32,450

for example accessing the received received country we are getting the country message here and we are



246

00:18:32,450 --> 00:18:37,880

starting to geocoding process after all these codes and after the geocoding process.



247

00:18:37,880 --> 00:18:42,920

Now it's time to modify the map itself.



248

00:18:43,220 --> 00:18:48,890

So here before the ading curly brace of the Smurfette I can't say.



249

00:18:49,310 --> 00:18:57,110

So let's create of the of type lot land and the name of this variable is going to be my country my country



250

00:18:57,110 --> 00:19:06,110

location assignment operator new law land survey to pass through arguments to the constructor.



251

00:19:06,110 --> 00:19:08,870

First we need to specify the latitude and longitude.



252

00:19:08,900 --> 00:19:14,210

So we created these two variables inside this class right country latitude and country longitude.



253

00:19:14,360 --> 00:19:15,710

So let's pass them here.



254

00:19:15,930 --> 00:19:19,610

Country latitude comma country longitude semi-colon.



255

00:19:20,000 --> 00:19:26,060

And here let's create a variable of type camera update and the name of this variable is camera update



256

00:19:26,600 --> 00:19:30,300

assignment operator Chamula update factory.



257

00:19:30,430 --> 00:19:32,440

That's Neil.



258

00:19:32,500 --> 00:19:34,150

Zoom here.



259

00:19:34,300 --> 00:19:37,480

So so he had a very 2:02 arguments to this method.



260

00:19:37,490 --> 00:19:40,940

First we need to pass an object of type let's land.



261

00:19:41,190 --> 00:19:43,250

And let me show you this method again.



262

00:19:43,400 --> 00:19:51,390

And the second argument is going to be the preciseness I should keep the zooming value that we need



263

00:19:51,420 --> 00:19:52,320

that you want to have.



264

00:19:52,410 --> 00:19:58,520

Is zooming out or this woman out for example if you passed 17 that is going to be the zooming value



265

00:19:58,520 --> 00:20:00,740

that you want to use on this location.



266

00:20:00,980 --> 00:20:02,900

So you are already familiar with that by the way.



267

00:20:02,900 --> 00:20:09,050

So first let's pass the last line Optik is it is going to be my country location comma and the zoomie



268

00:20:09,050 --> 00:20:12,290

radio is going to be seventeen point two.



269

00:20:12,460 --> 00:20:18,190

You can't use whatever value you want but I just I just prefer disvalue seventeen point two.



270

00:20:18,650 --> 00:20:21,740

Let me create a new line so that you can see what's going on here.



271

00:20:21,740 --> 00:20:28,910

So now we need to call this method that's actually fair to our map for instance valuable thoughts move



272

00:20:28,910 --> 00:20:30,260

camera.



273

00:20:30,440 --> 00:20:34,210

And I just need to pass this camera update to the Smurfit.



274

00:20:34,370 --> 00:20:34,950

Right.



275

00:20:35,210 --> 00:20:38,670

And now it's time to create a marker on this location.



276

00:20:38,670 --> 00:20:41,310

So just they've been here monitored options multiple options.



277

00:20:41,320 --> 00:20:48,120

Assignment operator new monitor options semicolon First we need to specify the position of this market



278

00:20:48,120 --> 00:20:48,460

option.



279

00:20:48,470 --> 00:20:50,820

So market options that position.



280

00:20:51,200 --> 00:20:53,940

So the position is going to be of type.



281

00:20:53,980 --> 00:20:55,130

And we know that here.



282

00:20:55,140 --> 00:20:58,370

So we actually already created a variable of type last thing.



283

00:20:58,490 --> 00:21:04,570

So I can pass that here in my country location semi-colon and let's specify the title of this market.



284

00:21:04,580 --> 00:21:08,380

So I can say multiple options that title.



285

00:21:08,420 --> 00:21:14,990

So we already created a value bet that is can be used for the title.



286

00:21:15,020 --> 00:21:20,570

So it is actually the country message here right by referring to the contrary message that we can actually



287

00:21:20,630 --> 00:21:24,930

access the intent that the info or the message of that country.



288

00:21:25,130 --> 00:21:30,420

So let's pass that here the title country message semicolon.



289

00:21:30,700 --> 00:21:35,570

And here we can also specify that snippet.



290

00:21:35,570 --> 00:21:38,640

So just typing here eruptions that snippets.



291

00:21:38,810 --> 00:21:41,700

So let's go to our country data source class here.



292

00:21:41,720 --> 00:21:45,740

If you scroll to the top here you can see that we have this default message here.



293

00:21:45,980 --> 00:21:50,760

So let's change this value to be happy for example.



294

00:21:50,830 --> 00:21:53,600

So let's go back to our map activity here.



295

00:21:53,720 --> 00:22:02,130

And now I can refer to this constant here so I can't say Country data source that default message semicolon.



296

00:22:02,390 --> 00:22:06,440

Now let's refer to a map instance valuable.



297

00:22:06,630 --> 00:22:10,320

That's at marker.



298

00:22:10,670 --> 00:22:13,740

So we have these small options here semicolon.



299

00:22:13,940 --> 00:22:16,340

So it's going to actually add this much to our map.



300

00:22:16,340 --> 00:22:23,000

So finally let's create a value of type circle options circle options circle options assignment operator



301

00:22:23,000 --> 00:22:25,950

new circle options semicolon.



302

00:22:26,090 --> 00:22:29,160

Say circle options that center.



303

00:22:29,590 --> 00:22:35,410

So we need to pass a value of type last line and it is going to be my country location semicolon and



304

00:22:35,420 --> 00:22:37,640

now we need to specify the radius.



305

00:22:37,760 --> 00:22:42,400

So I can say circle options that radius.



306

00:22:42,420 --> 00:22:53,020

So now I can say a 400 semicolon circle options thought stroke with stroke which I can pass a value



307

00:22:53,020 --> 00:22:53,650

of that float.



308

00:22:53,650 --> 00:22:57,200

Fourteen point five if semi-colon.



309

00:22:57,400 --> 00:23:02,380

And finally let's specify that scroll through each color circle options.



310

00:23:03,290 --> 00:23:06,480

That's true color color.



311

00:23:07,910 --> 00:23:09,330

Dots here.



312

00:23:09,350 --> 00:23:12,410

I can actually use on any nice semi-colon.



313

00:23:12,420 --> 00:23:19,980

And finally let's add let's add this sort of co-option to our map so map that at circle circle options



314

00:23:21,100 --> 00:23:23,220

certain call that's it.



315

00:23:23,220 --> 00:23:26,140

So I think now it's time to run the application.



316

00:23:26,140 --> 00:23:29,550

So let's run it and let's see what happens.



317

00:23:29,640 --> 00:23:31,300

Let me show you the emulator.



318

00:23:31,440 --> 00:23:34,280

So here you can see that our application is running on the simulator.



319

00:23:34,290 --> 00:23:41,970

But again the emulator does not fully support the speech recognition framework so you need to actually



320

00:23:42,330 --> 00:23:44,430

test this app on your actual device.



321

00:23:44,580 --> 00:23:48,930

So I'm going to take this up on my actual device and I'm going to record my screen device and then I'm



322

00:23:48,930 --> 00:23:51,260

going to show you what's going on here.



323

00:23:51,270 --> 00:23:57,450

So I tested the app on my android actual device and here first let me tell you that make sure that you



324

00:23:57,450 --> 00:23:59,650

have an Internet connection on your device.



325

00:23:59,790 --> 00:24:03,620

And as you can see my wife is actually turned on here.



326

00:24:03,780 --> 00:24:08,640

So let's let me actually play the video and then let me show you how it went.



327

00:24:08,640 --> 00:24:09,830

Let's play.



328

00:24:10,050 --> 00:24:18,300

So here I said Japan and here it actually opened the map activity so I zoomed out a little bit in order



329

00:24:18,300 --> 00:24:20,500

to show you this marker here.



330

00:24:21,920 --> 00:24:28,880

And you can see this little circle and if I actually zoom out in order to show you the Japan country



331

00:24:29,150 --> 00:24:33,850

here and here if I zoom in again now you can see this molecule option.



332

00:24:33,860 --> 00:24:40,490

This little circle and now I'm going to actually touch this mulcher and it says Welcome to Japan happy



333

00:24:40,500 --> 00:24:42,830

visiting be happy.



334

00:24:42,830 --> 00:24:43,590

Right.



335

00:24:43,610 --> 00:24:44,530

So that's it.



336

00:24:44,690 --> 00:24:47,530

OK everyone AB 79 is now finished.



337

00:24:47,540 --> 00:24:52,760

If you want to you can actually add more functionality to this application and you can actually make



338

00:24:52,940 --> 00:24:58,220

up your own and upload it to the Google Play store and in fact I recommend you to do that and make sure



339

00:24:58,370 --> 00:25:04,580

to actually share the link of your application in Google Play store with other students and beat me



340

00:25:05,060 --> 00:25:11,760

so that we can actually just give you some suggestions in order to make it better.



341

00:25:11,810 --> 00:25:13,610

So thank you very much for watching.



342

00:25:13,610 --> 00:25:18,820

The next app is going to be an e-commerce app so I'll see you in the next tutorial.
