1

00:00:00,350 --> 00:00:05,880

Hire everyone in this material we're going to go ahead and we're going to create a new app called Map



2

00:00:05,940 --> 00:00:07,320

speech app.



3

00:00:07,350 --> 00:00:12,240

So before that we need to make sure that our SDK components are actually updated.



4

00:00:12,420 --> 00:00:17,460

So here click on configure and then click on STK manager.



5

00:00:17,480 --> 00:00:20,730

So now you can see that is the case manager is open for us.



6

00:00:20,810 --> 00:00:27,920

Make sure that you have actually downloaded the Android 7 point 1.1 target or Android 7.0 or Android



7

00:00:27,920 --> 00:00:36,940

6 0 a marshmallow here or above and then make sure to actually click on these STK tools pop here.



8

00:00:37,780 --> 00:00:43,470

So here make sure to actually have this Android SDK tools installed.



9

00:00:43,510 --> 00:00:45,360

We have this android emulator.



10

00:00:45,370 --> 00:00:47,260

You can see that the update is available.



11

00:00:47,260 --> 00:00:53,160

So I'm going to update it here and we can see you can see that the Android platform tool.



12

00:00:53,170 --> 00:00:55,510

Here is updates are available here.



13

00:00:55,510 --> 00:00:56,990

Make sure to update this one too.



14

00:00:57,100 --> 00:01:00,820

So let me actually first show you all these components.



15

00:01:00,820 --> 00:01:02,530

So here let's scroll down.



16

00:01:02,530 --> 00:01:05,520

Here you can see this one here support repository.



17

00:01:05,800 --> 00:01:11,360

And you can see that the Google repository is actually that you have you can see this update is available.



18

00:01:11,560 --> 00:01:14,090

Make sure to also update this one too.



19

00:01:14,470 --> 00:01:17,800

In other words let's actually check this support repository here.



20

00:01:17,800 --> 00:01:19,140

This package.



21

00:01:19,450 --> 00:01:24,370

And now let's scroll to the top and you can see that this one Google Play services here.



22

00:01:24,460 --> 00:01:27,270

We can also update this package here.



23

00:01:27,310 --> 00:01:31,720

Check this check box and Android as is the case platform tools.



24

00:01:31,720 --> 00:01:33,600

Make sure to also check the street check box.



25

00:01:33,610 --> 00:01:35,410

And this one and emulator.



26

00:01:35,770 --> 00:01:40,370

So here let's just click on apply here.



27

00:01:41,460 --> 00:01:48,030

And it says the following components will be installed Android platform tools version this one twenty



28

00:01:48,150 --> 00:01:50,210

five point zero point six.



29

00:01:50,370 --> 00:01:56,460

And all these other components Android emulator Google Play services and Google repository these are



30

00:01:56,460 --> 00:02:02,340

the necessary components that we need in order to actually create this application that we're about



31

00:02:02,340 --> 00:02:03,410

to create.



32

00:02:03,420 --> 00:02:04,930

So let's click on OK.



33

00:02:05,280 --> 00:02:10,260

And now it's going to start actually updating these components for us.



34

00:02:10,260 --> 00:02:16,880

So I'm going to post the video and then I'm going to actually just again start recording the video after



35

00:02:16,890 --> 00:02:18,960

these components are updated.



36

00:02:19,380 --> 00:02:23,520

So now that those are necessary components are actually updated.



37

00:02:23,550 --> 00:02:26,710

Let's create an android studio project.



38

00:02:27,030 --> 00:02:32,900

So the application name is going to be app 79 app 79.



39

00:02:32,910 --> 00:02:35,710

You can name it whatever you want but I'm going to actually name it in this way.



40

00:02:35,720 --> 00:02:36,460

17:9.



41

00:02:36,810 --> 00:02:41,980

And then here you can specify the company domain to package name and a projected location.



42

00:02:42,210 --> 00:02:51,450

So just click next and here choose a 16 Android 4.1 jellybean for phone and tablet just click next and



43

00:02:51,450 --> 00:02:55,170

here choose any activity next.



44

00:02:55,170 --> 00:03:00,050

So here you can specify the activity and make sure that this checkbox is actually checked to generate



45

00:03:00,060 --> 00:03:00,910

lay out file.



46

00:03:01,060 --> 00:03:06,480

Lay out name is activity and underline main and make sure that this checkbox here is also checked backwards



47

00:03:06,480 --> 00:03:10,010

compatibility ABC1 but just click Finish.



48

00:03:10,020 --> 00:03:11,620

So let's wait a little bit here.



49

00:03:11,700 --> 00:03:17,630

So now that the project is created Let's go to our outfight activity and element of the exam.



50

00:03:17,630 --> 00:03:21,410

So here make sure to actually open these and review here.



51

00:03:21,690 --> 00:03:27,120

And if you don't have this android view you can't just click on these two little triangles here you



52

00:03:27,120 --> 00:03:30,740

can see this dropdown menu and then you can actually click on Android.



53

00:03:30,810 --> 00:03:31,260

OK.



54

00:03:31,410 --> 00:03:35,370

So let's open the rest folder and then open the layout folder.



55

00:03:35,610 --> 00:03:39,160

Double click on this activity underline minute exam here.



56

00:03:39,180 --> 00:03:44,160

So now let's double click on that in order to make this area wider so let's select this hello world



57

00:03:44,170 --> 00:03:47,300

text view and then present it on your keyboard.



58

00:03:47,730 --> 00:03:53,730

And here I want to switch to the take a stab at instead of constrained to lay out I'm going to change



59

00:03:53,730 --> 00:03:55,300

it to relatively fast.



60

00:03:55,410 --> 00:04:00,850

So just sitting here relatively out and you can see that the ending here is also relatively out.



61

00:04:00,900 --> 00:04:02,790

So let's go back to the design tab.



62

00:04:03,060 --> 00:04:09,810

Now here inside is pallet section let's click on layouts and let's strike a linearly old vertical here



63

00:04:10,110 --> 00:04:14,550

into this relatively out and put it here at the center of this relatively flat.



64

00:04:14,730 --> 00:04:15,380

OK.



65

00:04:15,810 --> 00:04:18,330

So you can see that this linearly or it's vertical here.



66

00:04:18,340 --> 00:04:24,180

It's lay out which is much apparent its length height is you can't see much apparent and the orientation



67

00:04:24,210 --> 00:04:25,520

is worth the color.



68

00:04:25,770 --> 00:04:29,080

Let's say that I text you into this linearly R20 cold.



69

00:04:29,130 --> 00:04:33,570

So just going all here inside is Pallot section and selectees takes.



70

00:04:33,630 --> 00:04:37,490

And just drag it here into these linearly out vertical.



71

00:04:37,490 --> 00:04:44,650

Here let's say this takes the takes of this it takes to be at the center of this takes you so selectees



72

00:04:44,660 --> 00:04:48,770

takes view here and lets you inside this property section.



73

00:04:48,770 --> 00:04:54,440

Let's go to the view all properties and let's search for the gravity attribute here.



74

00:04:54,470 --> 00:04:58,250

So search for gravity and let's actually find that.



75

00:04:58,260 --> 00:04:59,040

Here's what it is.



76

00:04:59,040 --> 00:05:02,380

This is actually the gravity attribute that we actually make a wider.



77

00:05:02,520 --> 00:05:07,500

So open this gravity here by just clicking on this little triangle here.



78

00:05:07,860 --> 00:05:12,280

And check this checkbox that says Center horizontal.



79

00:05:12,510 --> 00:05:17,250

Now we can see that the text of this text view is under center at the center of the state's view.



80

00:05:17,250 --> 00:05:18,090

Right.



81

00:05:18,090 --> 00:05:26,670

So let's actually here scroll down here and let's click on view fewer properties and specify an idea



82

00:05:26,670 --> 00:05:27,470

for the states.



83

00:05:27,480 --> 00:05:33,230

The idea is going to be the value and then present until General keyboard.



84

00:05:33,480 --> 00:05:34,370

So that's it.



85

00:05:34,380 --> 00:05:37,830

Let's go to our main activity class here.



86

00:05:37,830 --> 00:05:44,010

So here first of all we want to actually work with the speech recognition library with a speech recognition



87

00:05:44,010 --> 00:05:45,200

framework actually.



88

00:05:45,480 --> 00:05:49,410

So inside this class we need to create a constant.



89

00:05:49,410 --> 00:05:51,690

Actually that is called a request.



90

00:05:51,690 --> 00:06:00,510

So just they've been here private static final INT and the name of this constant here is going to be



91

00:06:00,570 --> 00:06:05,180

speech requests so make sure that the name of this constant is capitalized.



92

00:06:05,170 --> 00:06:11,230

Here is actually the convention the name of your constants always should be capitalized speech underline



93

00:06:11,410 --> 00:06:12,570

request.



94

00:06:12,950 --> 00:06:13,870

Right.



95

00:06:13,950 --> 00:06:19,170

And here put an assignment operator and assign the value number 10 to this constant.



96

00:06:19,170 --> 00:06:21,120

This is the request right.



97

00:06:21,150 --> 00:06:24,580

It doesn't matter what value you assign to this constant.



98

00:06:24,580 --> 00:06:28,660

The value the number that you assign to this constant must be unique.



99

00:06:28,920 --> 00:06:31,470

So I assign the value number 10 to this constant.



100

00:06:32,010 --> 00:06:39,060

So here first of all let me tell you that this application must be tested on a real Android device.



101

00:06:39,060 --> 00:06:44,850

You cannot test this app on an emulator because the emulator does not support speech recognition.



102

00:06:44,850 --> 00:06:52,230

So make sure that you have actually connected your Andretti voice to your computer and hear first inside



103

00:06:52,230 --> 00:06:53,740

this uncreate method.



104

00:06:53,760 --> 00:07:00,990

We must make sure that the user's device does actually support speech speech recognition.



105

00:07:00,990 --> 00:07:05,350

So in order to do that we need to actually access the package manager so to step in here.



106

00:07:05,460 --> 00:07:10,600

Package Manager and the name of this variable is going to be package manager assignment operator.



107

00:07:10,950 --> 00:07:12,890

And here I can say this.



108

00:07:12,900 --> 00:07:15,800

So this refers to an instance of type main activity.



109

00:07:16,020 --> 00:07:19,430

So notice that when ever that we actually run the application.



110

00:07:19,680 --> 00:07:24,570

And whenever the main activity is called and the main activity or the activity on Allemagne at this



111

00:07:24,580 --> 00:07:29,960

time it is actually on the screen an instance of the main activity class is going to be created.



112

00:07:29,970 --> 00:07:32,540

So this refers to that instance.



113

00:07:32,670 --> 00:07:35,690

So does that get package manager.



114

00:07:35,730 --> 00:07:43,590

So in this way we can access the package manager here and then let's create an new line here and here



115

00:07:43,590 --> 00:07:45,970

we need to access the information of the device.



116

00:07:46,140 --> 00:07:49,740

So we need to create a value of type list here.



117

00:07:49,860 --> 00:07:56,220

So notice that the list is actually an interface so just put up a pair of angle brackets and instead



118

00:07:56,220 --> 00:08:01,140

of angle brackets we need to specify that data type of the objects that are going to be inside this



119

00:08:01,140 --> 00:08:06,130

list which is going to be resolved in full resolve in full.



120

00:08:06,670 --> 00:08:10,760

And let me now let me show you the Android documentation.



121

00:08:10,910 --> 00:08:12,950

So here it is the android documentation.



122

00:08:12,950 --> 00:08:21,420

So inside the search bar here search for results in full right and it says and read AP eyes and do it



123

00:08:21,450 --> 00:08:26,060

that content that PM that result in for just click on this one here.



124

00:08:26,600 --> 00:08:29,060

So it says probably class resolve in 40.



125

00:08:29,060 --> 00:08:34,920

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



126

00:08:35,180 --> 00:08:41,150

So look at this description here it is information that is returned from resolving an intent against



127

00:08:41,300 --> 00:08:42,980

an intent filter.



128

00:08:43,040 --> 00:08:50,200

This partially corresponds to information collected from the and manifest that XML so let's scroll down



129

00:08:50,200 --> 00:08:50,420

here.



130

00:08:50,430 --> 00:08:55,840

Look at the summary here and here you can see all these actually the values here.



131

00:08:55,840 --> 00:08:56,450

Right.



132

00:08:56,740 --> 00:08:58,920

So let's go back to android studio.



133

00:08:58,930 --> 00:09:03,940

You can if you want to you can actually read these with this documentation here but I'm going to go



134

00:09:03,940 --> 00:09:07,310

back to android studio and here I can see a list.



135

00:09:07,390 --> 00:09:15,590

So the name of this valuable it's going to be a list of information assignment operator and now I'm



136

00:09:15,590 --> 00:09:21,320

going to access the package manager rowdier but that I created here so I can say package manager dot



137

00:09:21,680 --> 00:09:24,490

Querrey intent activities.



138

00:09:24,530 --> 00:09:25,310

So select this one.



139

00:09:25,310 --> 00:09:28,230

He had that query into the activities.



140

00:09:28,250 --> 00:09:34,900

So now let's go back to android documentation here and had inside the search bar here just typing here.



141

00:09:34,900 --> 00:09:38,660

Package Manager package manager.



142

00:09:39,170 --> 00:09:40,480

And here he can see this one here.



143

00:09:40,490 --> 00:09:45,680

And with that content that PM the package manager just click on this one here.



144

00:09:46,020 --> 00:09:48,020

So this is our package manager class.



145

00:09:48,030 --> 00:09:49,840

This is actually an abstract class.



146

00:09:49,860 --> 00:09:50,730

Right.



147

00:09:50,730 --> 00:09:52,950

So here let's look at this documentation.



148

00:09:52,950 --> 00:09:59,850

This description it says class for retrieving various kinds of information related to the application



149

00:09:59,850 --> 00:10:03,270

packages that are currently installed on the device.



150

00:10:03,330 --> 00:10:06,440

You can find this class pro-death package manager.



151

00:10:06,960 --> 00:10:10,340

So let's search for the query intent activities.



152

00:10:10,510 --> 00:10:14,920

So here if you are using a match you can't just hold down the comment and then press on that.



153

00:10:14,940 --> 00:10:21,150

If on your keyboard or if you are using a Windows machine just to hold down the control on your keyboard



154

00:10:21,210 --> 00:10:24,950

and then press on that if on your keyboard and here inside the search.



155

00:10:24,960 --> 00:10:33,500

But again it says for Querrey intent activities so this is the method that you're looking for.



156

00:10:33,500 --> 00:10:40,250

So if it says retrieve all activities that can be performed for the given intent.



157

00:10:40,520 --> 00:10:41,550

Right.



158

00:10:41,690 --> 00:10:49,370

So why we are calling this method because we want to make sure that we can actually access the speech



159

00:10:49,370 --> 00:10:51,550

recognition capability of the device.



160

00:10:51,860 --> 00:10:58,700

So let's go back to android studio here and let's let me show you first that this if it accepts two



161

00:10:58,700 --> 00:11:03,150

arguments the first one is of the intent and the second argument is actually of the integer.



162

00:11:03,170 --> 00:11:04,720

And it is flaks.



163

00:11:04,760 --> 00:11:06,110

So let's go back to our studio.



164

00:11:06,110 --> 00:11:09,120

So we need to pass these two arguments to this method here.



165

00:11:09,470 --> 00:11:13,630

So for the intent here let me create a new line and just step in here.



166

00:11:13,630 --> 00:11:20,180

New intent because we must pass a value of intent here to dismiss it for the first argument.



167

00:11:20,300 --> 00:11:26,420

So new intent and here instead Apprentice's of this intent we are actually calling the constructor of



168

00:11:26,420 --> 00:11:27,170

this intent here.



169

00:11:27,170 --> 00:11:27,910

Right.



170

00:11:27,980 --> 00:11:32,280

So in that Apprentice's I can say recognize their intent.



171

00:11:32,300 --> 00:11:34,250

So just they can recognize their intent.



172

00:11:34,250 --> 00:11:37,650

So let's let me actually show you the and regimentation.



173

00:11:37,760 --> 00:11:44,210

So here inside this search spirals so just referred to this recognizer intent here recognizer intent



174

00:11:44,630 --> 00:11:47,110

and Royte that speech that recognize that intent.



175

00:11:47,120 --> 00:11:48,050

Just click on it.



176

00:11:48,290 --> 00:11:53,380

So here you can see that this is actually a class that extends the object class.



177

00:11:53,420 --> 00:11:54,370

Right.



178

00:11:54,380 --> 00:12:00,570

So now let's look at this description it says constants for supporting speech recognition for thought



179

00:12:00,790 --> 00:12:01,960

and intent.



180

00:12:01,970 --> 00:12:08,650

This is very important constants for supporting speech recognition for starting an intent.



181

00:12:08,650 --> 00:12:15,490

So this means that we must start an intent in order to access this speech recognition.



182

00:12:15,500 --> 00:12:19,840

So let's let's go back to Andrew's studio and he had to step in here.



183

00:12:19,910 --> 00:12:24,090

Dot action recognize speech.



184

00:12:24,110 --> 00:12:30,620

So now let's go back to android city or to other documentation actually and here let's search for action



185

00:12:31,880 --> 00:12:33,920

underline recognize speech.



186

00:12:33,920 --> 00:12:42,320

So we get this one here it says starts an activity that will prompt the user for a speech and send it



187

00:12:42,350 --> 00:12:44,510

through a speech recognizer.



188

00:12:44,510 --> 00:12:45,630

Right.



189

00:12:45,740 --> 00:12:48,650

So it's going to start an activity for us this month.



190

00:12:48,680 --> 00:12:50,700

So let's go back to android studio.



191

00:12:50,720 --> 00:12:55,370

So here we want to actually start the actually recognize speech intent.



192

00:12:55,520 --> 00:12:56,050

OK.



193

00:12:56,210 --> 00:12:59,020

And here we are checking for that condition.



194

00:12:59,060 --> 00:13:04,160

So here you can see that this Smurfette quirky Internet activities needs the second arguments or just



195

00:13:04,160 --> 00:13:06,670

put a comma here which is going to be the flex.



196

00:13:06,680 --> 00:13:13,050

So for the Flex argument just passed the value zero here and at the end of our statement we must pass.



197

00:13:13,160 --> 00:13:14,870

We must put a semicolon here.



198

00:13:14,900 --> 00:13:16,100

Right.



199

00:13:16,100 --> 00:13:17,890

So here we are getting the information.



200

00:13:17,900 --> 00:13:19,320

The list of information actually.



201

00:13:19,340 --> 00:13:22,540

And here this variable holds those information.



202

00:13:22,880 --> 00:13:29,790

So now we want to make sure that the users the voice does actually support speech recognition.



203

00:13:29,810 --> 00:13:40,430

So here I can create an if statement so if list of information if a list of information that size is



204

00:13:40,460 --> 00:13:42,760

actually greater than zero.



205

00:13:43,180 --> 00:13:46,930

OK I just need to open and close this if they've been by using these curly braces.



206

00:13:46,970 --> 00:13:52,530

This means that if the size of this list is actually greater than zero.



207

00:13:52,550 --> 00:13:56,690

This means that the user's device does support speech recognition.



208

00:13:56,690 --> 00:14:02,280

In that case you are 100 and 50 percent sure that it is true.



209

00:14:02,450 --> 00:14:06,600

And we can actually create a host message that make text.



210

00:14:06,590 --> 00:14:10,260

So first we need to pass the context in activity that this on.



211

00:14:10,400 --> 00:14:24,310

The message is going to be your device your device doest support speech recognition speech recognition



212

00:14:25,390 --> 00:14:26,030

right.



213

00:14:26,230 --> 00:14:31,110

And then here put a actually an up and exclamation mark here.



214

00:14:31,450 --> 00:14:32,890

So let's put a comma here.



215

00:14:32,890 --> 00:14:38,860

And finally even if we just need to specify the duration of this message which is going to be the short



216

00:14:39,750 --> 00:14:42,920

lived short.



217

00:14:43,020 --> 00:14:46,630

And finally we need to call this show him Fifth this toast object.



218

00:14:46,800 --> 00:14:50,890

So let me create a new line here so that he can see what's going on here exactly.



219

00:14:52,390 --> 00:14:53,940

So this is our total message.



220

00:14:54,220 --> 00:15:00,760

So what happens if the user's device does not support this speech or speech recognition.



221

00:15:00,760 --> 00:15:05,830

In that case we are going to create an L statements or else I just need to open and close this statement



222

00:15:06,160 --> 00:15:07,460

by using these curly braces.



223

00:15:07,480 --> 00:15:11,900

Let's copy and paste this TOSed message here and put it here.



224

00:15:11,920 --> 00:15:19,900

Paste it here inside this block and here for the message I can see that your device does not support



225

00:15:19,960 --> 00:15:23,230

does not support speech recognition.



226

00:15:23,350 --> 00:15:30,010

So let's run the app on an emulator here because I want to show you that on the emulator here just to



227

00:15:30,010 --> 00:15:31,590

take this one and then click on OK.



228

00:15:31,600 --> 00:15:36,120

So here it says your device does support speech recognition.



229

00:15:36,110 --> 00:15:40,730

But yes it's going to actually show us dismiss this year but it's not actually exactly true.



230

00:15:40,930 --> 00:15:46,500

Because in order to test this feature we must use our own real Android device.



231

00:15:46,600 --> 00:15:47,090

OK.



232

00:15:47,530 --> 00:15:49,160

So that's it in the next story.



233

00:15:49,180 --> 00:15:51,740

We're going to continue building this application.



234

00:15:52,000 --> 00:15:53,050

Thank you very much for watching.



235

00:15:53,050 --> 00:15:57,430

If you have any questions about the concepts that I taught you in this lesson please post the discussion



236

00:15:57,430 --> 00:16:00,160

in the course and then I do my best to answer all of your questions.
