1

00:00:00,270 --> 00:00:05,760

Hire one in this story and we're going to go inside this main activity class and we're going to actually



2

00:00:05,760 --> 00:00:11,400

create a valuable model which is actually the country datasource.



3

00:00:11,610 --> 00:00:16,370

So here to stay in public static.



4

00:00:17,030 --> 00:00:24,720

And here just referred to the data type which is going to be country datasource and the name is going



5

00:00:24,720 --> 00:00:27,280

to be country Data Source semi-colon.



6

00:00:27,720 --> 00:00:31,260

So now let's go inside this and create Smurfette here.



7

00:00:32,460 --> 00:00:35,740

And now I want to actually initialize this instance.



8

00:00:35,870 --> 00:00:42,710

So just type in here country Data Source assignment operator new country datasource.



9

00:00:42,950 --> 00:00:48,830

So here you can see that we are actually calling the constructor of this class which is going to accept



10

00:00:49,130 --> 00:00:54,360

an argument of type hash table but we don't have any hash table value here.



11

00:00:54,440 --> 00:00:56,850

So we need to create it create that here.



12

00:00:56,960 --> 00:01:02,930

So before this line of code that actually creates an object of type of the country data source here



13

00:01:03,190 --> 00:01:06,010

we need to create a variable of a hash table.



14

00:01:06,230 --> 00:01:12,140

So just typing here inside is uncreate If you're just typing hash table and put a pair of angle brackets



15

00:01:12,140 --> 00:01:17,310

here add in say the angle brackets we need to specify the data type of the key and values.



16

00:01:17,330 --> 00:01:28,940

So just a bit here strange comma strange and the name is going to be countries and missus's assignment



17

00:01:28,940 --> 00:01:32,720

operator new hash table new hash table.



18

00:01:32,780 --> 00:01:33,260

That's it.



19

00:01:33,330 --> 00:01:34,280

Semicolon.



20

00:01:34,280 --> 00:01:40,170

So we created an object of type hash table and we assigned this object to this variable.



21

00:01:40,400 --> 00:01:46,500

So this hash table variable is going to accept values actually keys and values of types 3.



22

00:01:46,550 --> 00:01:55,450

So now after this line of code here I can say countries and messages that puts So here and calling that



23

00:01:55,610 --> 00:01:58,100

method put on this hash table right here.



24

00:01:58,120 --> 00:02:01,300

So you can see this Myford pute needs two arguments.



25

00:02:01,300 --> 00:02:04,470

The first argument is going to be off the string which is going to be the key.



26

00:02:04,750 --> 00:02:09,030

And the second argument is going to be off Eppstein which is going to be the value.



27

00:02:09,250 --> 00:02:10,820

So just put two coats here.



28

00:02:11,350 --> 00:02:19,460

And for the cutest they've been here for example Canada Canada comma and the value is going to be just



29

00:02:19,570 --> 00:02:20,280

two coats.



30

00:02:20,330 --> 00:02:21,430

Welcome to Canada.



31

00:02:21,680 --> 00:02:23,520

Welcome to Canada.



32

00:02:25,140 --> 00:02:26,240

Semicolon.



33

00:02:26,670 --> 00:02:33,720

Let's actually again just refer to this hash table label countries and messages that put just put two



34

00:02:33,720 --> 00:02:34,650

coats here.



35

00:02:34,650 --> 00:02:37,250

This term just that refers to this France.



36

00:02:37,470 --> 00:02:38,420

Come on.



37

00:02:38,760 --> 00:02:42,320

And for example for the message I can say welcome to France.



38

00:02:42,340 --> 00:02:44,360

Welcome to France.



39

00:02:44,700 --> 00:02:50,020

Happy visiting or I can't say happy semicolon here for this channel for instance.



40

00:02:50,040 --> 00:03:00,210

I can also say happy visiting happy and here again countries and messages that put so at this time.



41

00:03:00,270 --> 00:03:10,470

For example I can't say Brazil Brazil come on two coats will come to Brazil



42

00:03:13,460 --> 00:03:20,510

happy visiting semicolon countries and messages that puts two coats.



43

00:03:20,530 --> 00:03:28,240

United States United States Khama two coats.



44

00:03:28,290 --> 00:03:34,500

Come to United States happy visiting semi-colon.



45

00:03:34,870 --> 00:03:38,780

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



46

00:03:39,780 --> 00:03:42,350

I could also put other countries here.



47

00:03:43,060 --> 00:03:53,340

So I just say in countries and messages that puts two coats for example Japan come on two coats.



48

00:03:53,350 --> 00:03:54,880

Welcome to Japan.



49

00:03:54,880 --> 00:03:56,600

Welcome to Japan.



50

00:03:56,620 --> 00:03:58,630

Happy visiting semi-colon.



51

00:03:58,780 --> 00:04:03,340

So that's it is are the countries that I specified here if you want to you can actually specify more



52

00:04:03,340 --> 00:04:08,490

countries but as an example I just specify these countries here.



53

00:04:08,680 --> 00:04:15,100

So now that we have this hash table variable which then passed to the constructor of this country data



54

00:04:15,100 --> 00:04:15,880

source class.



55

00:04:15,940 --> 00:04:18,600

So I can actually pass this value.



56

00:04:18,670 --> 00:04:24,810

Countries and countries and messages here to this constructor's semicolon.



57

00:04:24,820 --> 00:04:31,360

So now we created a new instance of country data source and we assigned this instance to this country



58

00:04:31,360 --> 00:04:32,840

Data Source variable.



59

00:04:32,920 --> 00:04:33,480

Right.



60

00:04:33,820 --> 00:04:38,200

So now let's go to the on activity results method here.



61

00:04:38,200 --> 00:04:42,360

Let's scroll down here so here you can see that we're actually getting there.



62

00:04:42,520 --> 00:04:49,690

Actually the voice words from their voice intent and we are also getting the confidence levels of our



63

00:04:50,050 --> 00:04:52,730

voice recognition framework.



64

00:04:52,960 --> 00:04:58,480

So you know what is this confidence level it is actually related to the preciseness of each word that



65

00:04:58,480 --> 00:04:59,840

is said by the user.



66

00:04:59,970 --> 00:05:00,570

OK.



67

00:05:01,000 --> 00:05:06,520

And here we can see that they created a variable of that integer and we created a for loop in order



68

00:05:06,520 --> 00:05:10,330

to access these words and output them to the screen.



69

00:05:10,570 --> 00:05:17,410

But here we don't want to actually access the user words and output the output to the screen because



70

00:05:17,680 --> 00:05:21,300

here we are actually working with a map right.



71

00:05:21,340 --> 00:05:29,770

So I want to actually for example if the user says Canada I want a market to be created on the Canada



72

00:05:29,920 --> 00:05:33,950

country and I want that message to be shown to the user.



73

00:05:33,970 --> 00:05:37,900

So here we don't need these integer value but and this for in loop here.



74

00:05:37,900 --> 00:05:40,950

So let's highlight these lines of code here.



75

00:05:40,960 --> 00:05:44,590

This rally but this were in loop and let's delete these codes.



76

00:05:44,710 --> 00:05:48,370

Or for example I can actually create a comment Amante line come in.



77

00:05:48,370 --> 00:05:53,920

So it's actually I'm going to create multiline comments so here you can see that these codes are actually



78

00:05:53,920 --> 00:05:55,020

commented out.



79

00:05:55,210 --> 00:05:57,100

We're not going to work with these codes anymore.



80

00:05:57,310 --> 00:06:05,890

So now I'm going to actually for example put to put more quotes here put my own logic here and here



81

00:06:05,890 --> 00:06:10,720

you are going to see that you're going to work with the map by using this speech recognition framework.



82

00:06:10,720 --> 00:06:12,460

So let's see how we can do that.



83

00:06:12,460 --> 00:06:15,930

So here let's create a variable of type streams.



84

00:06:16,510 --> 00:06:20,670

And the name of this variable is going to be country country.



85

00:06:20,670 --> 00:06:22,240

Matched right.



86

00:06:22,320 --> 00:06:30,960

Assignment operator and now I'm going to refer to the country Data Source instance that match with minimum



87

00:06:30,960 --> 00:06:33,970

confidence level of user votes.



88

00:06:33,990 --> 00:06:36,300

So we are calling this an effect on this instance.



89

00:06:36,300 --> 00:06:42,510

And here you can see that we need to pass a value of tape released to the Smurfette and we need to also



90

00:06:42,510 --> 00:06:44,150

pass the confidence levels.



91

00:06:44,190 --> 00:06:46,410

So we already have these values.



92

00:06:46,410 --> 00:06:48,620

Your voice forth and comfort levels.



93

00:06:48,750 --> 00:06:51,550

So I can actually as an as the first argument I can pass.



94

00:06:51,570 --> 00:06:54,060

Voice words come on.



95

00:06:54,420 --> 00:06:59,880

And as the second argument I get past the conflict levels it's just I think he had conflict levels semicolon.



96

00:07:00,120 --> 00:07:06,150

So let me create a new line here so you can see that we are calling this method in this instance voice



97

00:07:06,150 --> 00:07:07,510

words comfort levels.



98

00:07:07,530 --> 00:07:15,270

Now we are assigning the return value of the Smurfette to this variable of type string.



99

00:07:15,270 --> 00:07:18,940

So you know that the return type of this method is actually off the street.



100

00:07:19,020 --> 00:07:19,470

Right.



101

00:07:19,680 --> 00:07:24,750

So the return value is a string value so it is going to be assigned to this string valuable country



102

00:07:24,750 --> 00:07:26,040

matched.



103

00:07:26,160 --> 00:07:32,000

So let's change this rowdier been name to country matched up with user Vort.



104

00:07:32,010 --> 00:07:36,000

It's more meaningful user actually Vort.



105

00:07:36,140 --> 00:07:43,250

So now I can say so here you can see that now that we have this country matched it use a reverse string



106

00:07:43,250 --> 00:07:44,540

value here.



107

00:07:44,720 --> 00:07:49,460

We want to pass this string value to the map activity.



108

00:07:49,460 --> 00:07:52,520

So you already know that we have two activities inside our project.



109

00:07:52,520 --> 00:07:59,420

The first one is the main activity and the second one is the map activity that contains the map right.



110

00:07:59,480 --> 00:08:05,810

So I want to send this data for example this country must use the reward value to the math activity



111

00:08:05,840 --> 00:08:11,690

so that the math activity can actually understand what is this specific award and then the map is going



112

00:08:11,690 --> 00:08:13,700

to respond according to that word.



113

00:08:13,730 --> 00:08:20,270

For example if the user says Canada does Canada work is going to be actually passed to the math activity



114

00:08:20,600 --> 00:08:22,980

and the math activity is going to respond to this.



115

00:08:23,000 --> 00:08:28,490

And it's going to actually show the user a place in Canada and it's going to show this message that



116

00:08:28,520 --> 00:08:33,490

is specified in say these are created for me show you that in fifth year you can see that here.



117

00:08:33,510 --> 00:08:37,160

As we said Canada Welcome to Canada happy visiting.



118

00:08:37,220 --> 00:08:37,790

Right.



119

00:08:37,910 --> 00:08:39,230

So let's scroll down here.



120

00:08:39,470 --> 00:08:45,140

Don't worry if you don't understand it now it's going to make sense later for not just know that we



121

00:08:45,180 --> 00:08:46,730

are going to actually pass.



122

00:08:46,730 --> 00:08:49,870

We want to send this value to them or activity.



123

00:08:50,080 --> 00:08:57,200

So after this line of code we need to create a new intent of type that actually of that intent and the



124

00:08:57,200 --> 00:09:03,680

name of this intent is going to be my intent which is going to actually transition from this activity



125

00:09:03,920 --> 00:09:05,100

to the map activity.



126

00:09:05,240 --> 00:09:11,780

So just they've been here intent and the name of this intent is going to be my map activity my math



127

00:09:11,870 --> 00:09:16,030

activity or my activity is it's more meaningful.



128

00:09:16,780 --> 00:09:21,960

Assignment operator so not just step he had new intent.



129

00:09:22,100 --> 00:09:27,360

So as the first argument we need to pass the context which is going to be main activity that this come



130

00:09:27,360 --> 00:09:27,740

on.



131

00:09:27,900 --> 00:09:31,430

There's such an argument is going to be class that we want to transition to.



132

00:09:31,620 --> 00:09:37,520

But it's going to be mapped activity maps activity that class flight semicolon.



133

00:09:37,980 --> 00:09:46,080

So because we want to send our data to this my math activity here I need to actually refer to this intent



134

00:09:46,110 --> 00:09:50,280

to this activity that puts extra.



135

00:09:50,340 --> 00:09:56,960

So as the key is you know that we created a key inside this country data source.



136

00:09:56,990 --> 00:10:02,130

So let's go to this country that are sort of class here you can see that in line number 15 we created



137

00:10:02,300 --> 00:10:10,920

a constant named country key here so we can actually specify this constant is actually the key here



138

00:10:11,220 --> 00:10:15,610

as the key of our here of our intent.



139

00:10:15,930 --> 00:10:21,680

And we can sense the state of this country must be the user of what you to the math activity class.



140

00:10:21,780 --> 00:10:23,060

So I can refer.



141

00:10:23,060 --> 00:10:26,060

So let me go back to this country that are class.



142

00:10:26,180 --> 00:10:29,020

Notice that this is actually a constant.



143

00:10:29,310 --> 00:10:31,710

And this is a static constant.



144

00:10:31,710 --> 00:10:34,430

This means that this is actually class A class constant.



145

00:10:34,470 --> 00:10:39,290

And by just referring to the name of the class we can call this constant on this class.



146

00:10:39,300 --> 00:10:45,270

So let's go back to our main activity class and here is the key I can refer to this country data source



147

00:10:45,270 --> 00:10:48,290

class country Data Source thought.



148

00:10:48,480 --> 00:10:53,730

And here I can say country key if I go to this country get a classic and see that we have this country



149

00:10:53,730 --> 00:10:54,420

key here.



150

00:10:54,420 --> 00:10:56,900

So let's go back to main I keep the class comma.



151

00:10:57,040 --> 00:11:03,270

And now I need to pass the value which is going to be related to this key and it is country matched



152

00:11:03,270 --> 00:11:08,450

with user what semicolon that that create a new line so that they can see what's going on here.



153

00:11:08,640 --> 00:11:13,070

And finally we need to call this Tarth activity method here.



154

00:11:13,200 --> 00:11:17,430

So just step in here start actually with you notice that we are not using start activity for results



155

00:11:17,430 --> 00:11:21,090

because we don't want we don't try to actually get any data from the math activity.



156

00:11:21,180 --> 00:11:24,130

We just want to send this data to the map activity.



157

00:11:24,210 --> 00:11:24,640

OK.



158

00:11:24,810 --> 00:11:28,050

So what is that you're using this method instead on activity result.



159

00:11:28,050 --> 00:11:31,110

If it does an activity it is again inside the if statement.



160

00:11:31,320 --> 00:11:37,620

It is is step in it's going to be executed when the intent when the voice into it is actually finished



161

00:11:37,680 --> 00:11:38,380

executing.



162

00:11:38,400 --> 00:11:43,800

And it is eliminated and we are back to this main activity and here you are getting those data from



163

00:11:43,800 --> 00:11:47,450

the voice intent and now inside is intent.



164

00:11:47,460 --> 00:11:52,160

Instead the main activity after getting the data from the user world.



165

00:11:52,160 --> 00:11:59,820

Here you can see we can actually call it start activity and we can open the map my map activity that's



166

00:11:59,900 --> 00:12:00,700

it.



167

00:12:00,740 --> 00:12:07,380

So now let's actually let me show you the project and review here so you can see that it is actually



168

00:12:07,380 --> 00:12:08,860

in Project view.



169

00:12:08,990 --> 00:12:13,020

If you are at the top just click on View tool windows project you can see that.



170

00:12:13,080 --> 00:12:19,440

Now my project is in Project view here this project structure and I need to change you to Android.



171

00:12:19,530 --> 00:12:19,980

OK.



172

00:12:20,100 --> 00:12:22,190

So here you can see this little triangle here.



173

00:12:22,200 --> 00:12:26,300

If I click on this dropdown menu I just click on this Android.



174

00:12:26,400 --> 00:12:30,220

So it is actually in and with view of the app folder.



175

00:12:30,240 --> 00:12:34,020

And let's open the manifest for that just double click on it this way.



176

00:12:34,020 --> 00:12:40,450

Here let me turn this tap here so let me scroll down here so you can see that we have two activities.



177

00:12:40,680 --> 00:12:44,050

The first one is the main activity here.



178

00:12:44,340 --> 00:12:48,480

And the second activity is this tech here which is for the mass activity.



179

00:12:48,690 --> 00:12:53,610

So previously we specified that this mass activity is going to be the launcher activity right.



180

00:12:53,610 --> 00:12:59,700

Because of this intense to attack here we are satisfied that it is going to be the main action and it



181

00:12:59,700 --> 00:13:01,590

is going to be the luncher activity.



182

00:13:01,620 --> 00:13:08,280

So now we want to actually say that now the main activity is going to be the larger activity not this



183

00:13:08,280 --> 00:13:09,320

maps activity.



184

00:13:09,600 --> 00:13:17,780

So here for this mapping activity here just a select or highlight this intent intent to filter here



185

00:13:17,800 --> 00:13:26,380

this intent to attack just highlighted and just cut this piece of code and let's scroll to the top.



186

00:13:26,390 --> 00:13:32,240

And for this activity here for this main activity inside this tag place this value here.



187

00:13:32,240 --> 00:13:35,480

So now the main activity is the lantern activity.



188

00:13:35,490 --> 00:13:41,010

If you run the application here now you can see that it's going to actually open the main activity first.



189

00:13:41,300 --> 00:13:47,010

Let me run the app now so it is actually choosing the Nexus API.



190

00:13:47,270 --> 00:13:49,760

And I should say if are 25 that's really kind of cool.



191

00:13:50,000 --> 00:13:52,840

So here you can't see that or app is running on the simulator.



192

00:13:52,850 --> 00:13:56,630

And now you can see that the main activity is there luncher activity.



193

00:13:56,840 --> 00:13:58,760

So let's go back to android studio.



194

00:13:58,940 --> 00:14:00,220

We're not finished yet.



195

00:14:00,350 --> 00:14:02,260

You can see that inside the main activity here.



196

00:14:02,360 --> 00:14:07,340

And inside these are like TVs result we get the user vort and we send this data to the mouse activity



197

00:14:07,380 --> 00:14:10,530

and now we actually opened the math activity right.



198

00:14:10,700 --> 00:14:17,750

But now we need to go to the maps activity class and here inside this class we need to handle the responses



199

00:14:17,750 --> 00:14:22,250

we need to actually handle the data that we get from the main activity class.



200

00:14:22,250 --> 00:14:23,650

So how we can do that.



201

00:14:23,660 --> 00:14:29,030

So I think that's enough for this tutorial in the next tutorial we can actually work with this working



202

00:14:29,150 --> 00:14:30,920

inside this mass activity class.



203

00:14:30,980 --> 00:14:35,540

If you have any questions please post the discussion in the course and then I do my best to answer all



204

00:14:35,540 --> 00:14:36,550

of your questions.



205

00:14:36,680 --> 00:14:39,120

Thank you very much for watching and I'll see you in the next tutorial.
