1

00:00:00,620 --> 00:00:09,470

Let's go ahead and create a listener for this PTEN take the picture Potten so I can say PTEN take a



2

00:00:09,470 --> 00:00:15,450

picture that said unclick listener Pythian that take a picture.



3

00:00:15,760 --> 00:00:21,070

That's what I collect listener and now I need to pass the context so I can just pass an activity that



4

00:00:21,070 --> 00:00:21,850

is.



5

00:00:22,020 --> 00:00:28,610

So the main activity that this is going to be actually a listener when the user interacts with is spartan.



6

00:00:28,850 --> 00:00:35,030

So in order for this main activity class to be the listener in order to be notified whenever they use



7

00:00:35,030 --> 00:00:42,230

that interacts with this PTEN taking part in this class must implement their unclick listener interface.



8

00:00:42,230 --> 00:00:44,100

So you're already familiar with that right.



9

00:00:44,180 --> 00:00:49,520

So I just need to scroll to the top and here it says main activity extends app compacter activity.



10

00:00:49,580 --> 00:00:56,760

And here I can say space implements view dot and click click center.



11

00:00:57,200 --> 00:01:02,500

So the idea that this class is actually implementing this view that unclick this in an interface this



12

00:01:02,500 --> 00:01:05,930

class must provide an implementation for the unclick my foot.



13

00:01:05,930 --> 00:01:07,200

So let's scroll down here.



14

00:01:07,280 --> 00:01:12,260

And after the end in curly brace of this uncreate method and before the end and curly brace of this



15

00:01:12,410 --> 00:01:16,980

main activity class I had just been unclick and that person interchange keyboard.



16

00:01:17,000 --> 00:01:19,120

So now we are all we're writing this.



17

00:01:19,130 --> 00:01:23,090

Unclear if an insider view that unclick the center interface.



18

00:01:23,180 --> 00:01:26,270

So whenever that is that actually interacts with the SBT and take a picture.



19

00:01:26,270 --> 00:01:29,450

But in this Smurfette here unclick is going to be called.



20

00:01:29,450 --> 00:01:29,860

Right.



21

00:01:30,050 --> 00:01:35,630

But because we have two buttons inside our application we have the first one BTA take a picture and



22

00:01:35,630 --> 00:01:38,210

the second one is PTEN save the picture.



23

00:01:38,210 --> 00:01:41,780

So let's also create a listener for this SBT and save the picture.



24

00:01:41,780 --> 00:01:47,300

So after this line of code that sets the listener for the spit take a picture or can just say PTEN safety



25

00:01:47,300 --> 00:01:51,040

feature that sits unclick listener.



26

00:01:52,370 --> 00:01:58,610

And here again I can just pass the context meant I think that that is so now because this class is actually



27

00:01:58,610 --> 00:02:02,270

conforming to this view that unclick us in an interface.



28

00:02:02,360 --> 00:02:06,940

And if you are providing MF Smurfit inside that interface here.



29

00:02:07,000 --> 00:02:12,350

So whenever they use it actually interacts with these two buttons into hip or Pythian save the picture



30

00:02:12,370 --> 00:02:13,840

this if it is going to be called.



31

00:02:13,880 --> 00:02:15,310

So you're already familiar with that.



32

00:02:15,310 --> 00:02:15,960

Right.



33

00:02:15,980 --> 00:02:18,990

So how we can actually differentiate between these two buttons.



34

00:02:19,190 --> 00:02:24,710

By using this view here it is you object that I to receive as an argument from the Songkhla if I can



35

00:02:25,010 --> 00:02:32,340

say this uncle if I can say if this is actually the name of this argument I can change the name of this



36

00:02:32,460 --> 00:02:33,490

argument to view.



37

00:02:33,570 --> 00:02:35,000

It's better to name it view.



38

00:02:35,190 --> 00:02:41,730

So if view that ID so let's actually get just a bit here.



39

00:02:41,790 --> 00:02:56,650

ID is equal to or data ID but Pythian take a picture then in that case here we are a hundred and fifty



40

00:02:56,840 --> 00:03:00,710

percent sure that is pretty and take a picture is actually clicked.



41

00:03:00,710 --> 00:03:06,440

So inside this statement you can actually put the logic that we want to be executed Whenever to use



42

00:03:06,440 --> 00:03:10,730

that interacts with this and take a picture so I can create an ELSE IF statement here.



43

00:03:10,730 --> 00:03:17,960

So after the head curly brace of this if statement I can say Elsy else if inside the apprentice's I



44

00:03:17,960 --> 00:03:29,300

can say view that get Id get ID right and then put an equal operator here Aard thought id that Pythian



45

00:03:29,300 --> 00:03:36,410

save the picture here and here you are 100 I'm 50 percent sure that this beauty and save the picture



46

00:03:36,410 --> 00:03:37,370

is actually clicked.



47

00:03:37,370 --> 00:03:39,680

So it is going to ask you this if statement.



48

00:03:39,680 --> 00:03:45,560

So how this is how we can actually differentiate between Actually these buttons.



49

00:03:45,590 --> 00:03:48,320

So let's go inside the curly braces of this statement.



50

00:03:48,340 --> 00:03:52,880

If you view that it is R that R D that BT and take a picture.



51

00:03:52,880 --> 00:04:01,620

Now I can say so here because we want to actually get the user's permission in order to access the camera.



52

00:04:01,880 --> 00:04:03,170

It is very important.



53

00:04:03,170 --> 00:04:04,110

It is a must actually.



54

00:04:04,220 --> 00:04:08,480

To ask the user in order to get the permission to access the camera.



55

00:04:08,540 --> 00:04:10,810

So we must actually ask the user for that.



56

00:04:10,810 --> 00:04:17,650

So just type in here in it and the name of this variable is going to be permeation result permission



57

00:04:18,060 --> 00:04:19,190

resolved.



58

00:04:19,580 --> 00:04:29,080

Assignment operator context compact context compact that a check self permission.



59

00:04:29,160 --> 00:04:35,170

So here first we need to pass the context which is going to be main activity that this comma.



60

00:04:35,490 --> 00:04:43,050

And for the second argument we need to say manifest such as they've been here manifest that permission



61

00:04:43,560 --> 00:04:45,650

DOT camera.



62

00:04:45,750 --> 00:04:50,360

So we want to ask the user to give us the permission to access the camera.



63

00:04:50,580 --> 00:04:53,210

So we need to also put this permission inside the manifest file.



64

00:04:53,220 --> 00:04:58,890

Let's actually open the address structure here at the top and you just click on View and then tool windows



65

00:04:58,920 --> 00:05:01,070

and then click on project here.



66

00:05:01,080 --> 00:05:02,830

This is our Android view right.



67

00:05:03,060 --> 00:05:06,390

So you can see this inside this app folder we have this manifests.



68

00:05:06,420 --> 00:05:07,810

So just double click on it.



69

00:05:08,010 --> 00:05:12,060

And here if you open this for the audience it is our manifest that is him on file.



70

00:05:12,300 --> 00:05:14,100

So inside this manifest.



71

00:05:14,100 --> 00:05:14,650

Hi.



72

00:05:14,770 --> 00:05:15,260

OK.



73

00:05:15,300 --> 00:05:19,390

Before this application here and inside its manifest manifest.



74

00:05:19,530 --> 00:05:24,020

Let me actually just double click on this tab in order to make this area either just open a tag and



75

00:05:24,030 --> 00:05:27,220

just type in here user's permission.



76

00:05:27,420 --> 00:05:29,430

So the permission is going to be camera.



77

00:05:29,460 --> 00:05:29,980

Right.



78

00:05:30,150 --> 00:05:32,800

So just they've been here and read the permission of the camera.



79

00:05:33,000 --> 00:05:39,840

And then just sell clothes this tag by using this slash and this and tag here.



80

00:05:39,840 --> 00:05:44,060

So now you are actually putting this permission here let's go to them in the class.



81

00:05:44,100 --> 00:05:47,360

So here we are checking for that condition for that permission.



82

00:05:47,370 --> 00:05:52,110

We are taking that if the permission is actually given to us by the user.



83

00:05:52,320 --> 00:05:57,660

Then the result is going to be actually assigned to this valuable permission or as a result.



84

00:05:57,870 --> 00:05:59,990

So let's create an if statement here.



85

00:06:00,030 --> 00:06:08,580

After this line of code after this valuable so I can say if permission result is equal to package manager



86

00:06:09,390 --> 00:06:16,880

that permission granted I can just open and close this statement by using these curly braces.



87

00:06:16,880 --> 00:06:23,960

Now I can say that the user has given us to access the camera so it is possible to actually access the



88

00:06:23,960 --> 00:06:27,680

camera right but we need to actually check for another condition.



89

00:06:27,680 --> 00:06:30,250

What if the user doesn't have the camera.



90

00:06:30,260 --> 00:06:32,620

What if the user's device doesn't have a camera.



91

00:06:32,870 --> 00:06:40,110

So for that case you also must create an if statement in order to check for that specific condition.



92

00:06:40,130 --> 00:06:43,760

So this if statement is checking for their permission granted.



93

00:06:43,760 --> 00:06:44,280

Right.



94

00:06:44,300 --> 00:06:48,990

So what happens if the user doesn't allow us to actually access the camera.



95

00:06:49,010 --> 00:06:53,920

In that case we want to actually ask the user to give us the permission to access the camera.



96

00:06:54,080 --> 00:06:59,850

So after this if statement after the end curly brace of this if statement if statement I can't say as



97

00:07:00,540 --> 00:07:04,640

I don't like could open and close this statement by using these curly braces so that I can actually



98

00:07:04,640 --> 00:07:12,390

request that I can say Let me just paste this line of quote here so you can see activity compact that



99

00:07:12,390 --> 00:07:14,180

requires the permissions.



100

00:07:14,560 --> 00:07:19,180

So first we need to pass the context which is going to be main activity that this and for the second



101

00:07:19,180 --> 00:07:26,320

argument we need to pass an ad a string values that actually holds the permissions that we want to actually



102

00:07:26,800 --> 00:07:27,740

ask the user.



103

00:07:27,940 --> 00:07:32,730

So we want to use user only allow us to access the cameras so we have only an outrage.



104

00:07:32,740 --> 00:07:36,080

So News Stream at 8:00 that this audio only has one value.



105

00:07:36,130 --> 00:07:36,870

Right.



106

00:07:36,910 --> 00:07:41,120

So instead of Colibri inside the curly braces you can see that we have this permanent manifest that



107

00:07:41,130 --> 00:07:42,330

we're in that camera.



108

00:07:42,520 --> 00:07:46,540

And for the second argument you can see it is actually this request the court.



109

00:07:46,690 --> 00:07:52,120

So this request card is used for actually requesting their permission.



110

00:07:52,120 --> 00:07:57,100

So it is one case it doesn't really matter what you put here but it must be a unique value a unique



111

00:07:57,100 --> 00:07:57,580

number.



112

00:07:57,580 --> 00:07:59,290

So what is ok here.



113

00:07:59,290 --> 00:08:01,080

So let's go inside this statement.



114

00:08:01,200 --> 00:08:06,590

So if they use that actually has given us the permission to access the camera I can't say.



115

00:08:06,730 --> 00:08:10,830

So first of all we need to access the package manager so I can't say enough.



116

00:08:10,870 --> 00:08:12,160

So here I am.



117

00:08:12,250 --> 00:08:13,960

First of all let's create a body.



118

00:08:13,970 --> 00:08:20,020

But of the package manager or package manager package manager assignment operator gets package manager



119

00:08:20,160 --> 00:08:20,950

semicolon.



120

00:08:21,240 --> 00:08:21,850

Right.



121

00:08:21,880 --> 00:08:28,360

So in this way we are actually accessing the package manager of the application that has the specific



122

00:08:28,360 --> 00:08:29,440

features of the device.



123

00:08:29,440 --> 00:08:36,310

For example if the user has a camera or not this package manager can have those values those data.



124

00:08:36,310 --> 00:08:47,290

And now I can say if package manager DOT has system feature package manager with capital P write package



125

00:08:47,290 --> 00:08:55,310

manager that Tamarod package manager that feature other like camera then open and close open and close



126

00:08:55,310 --> 00:09:00,360

this if statement by using the curly braces so this means if the device if the package manager that



127

00:09:00,430 --> 00:09:03,700

has system feature package manager that feature tramadol.



128

00:09:03,730 --> 00:09:08,250

If that device has actually a camera and B can access that camera right.



129

00:09:08,290 --> 00:09:15,110

If the camera is working properly and we can access it now I can say we need to create an intent for



130

00:09:15,110 --> 00:09:15,650

the camera.



131

00:09:15,650 --> 00:09:24,030

So here I can say intent and the name of this entity is going to be camera intent assignment operator



132

00:09:24,210 --> 00:09:38,000

new new intent an inside Apprentice's I can't say Medhi us or that action image capture because we want



133

00:09:38,000 --> 00:09:43,750

to actually allow the user to access the camera and take a picture.



134

00:09:43,770 --> 00:09:50,460

We want this intense media store that actual image capture we are creating an instant specific for that.



135

00:09:50,510 --> 00:09:52,310

So let's put a semicolon here.



136

00:09:52,310 --> 00:09:54,980

So it's going to access the camera application right.



137

00:09:55,460 --> 00:09:59,380

And here I can say start activity for result.



138

00:09:59,390 --> 00:10:06,530

So because we want to get that image that is actually captured by the user by using the camera we need



139

00:10:06,530 --> 00:10:09,570

to use this method start activity for result.



140

00:10:09,770 --> 00:10:12,830

So as you can see this and if it needs two arguments the first one is the intent.



141

00:10:12,830 --> 00:10:18,850

So if you have the intent the camera intent come up the next argument is going to be that requires the



142

00:10:18,870 --> 00:10:24,390

court which is very important because by using this request code you are accessing the camera.



143

00:10:24,410 --> 00:10:24,690

Right.



144

00:10:24,710 --> 00:10:25,730

And we're getting that picture.



145

00:10:25,730 --> 00:10:31,230

And later when we want to get that picture and put it on our image view we must use that request court



146

00:10:31,250 --> 00:10:33,350

in order to identify that image.



147

00:10:33,350 --> 00:10:34,700

This is very important.



148

00:10:34,700 --> 00:10:38,780

So let's provide and our request let's actually scroll to the top.



149

00:10:38,780 --> 00:10:48,350

And inside this class after declaring these variables I can actually say a private or private static



150

00:10:49,160 --> 00:10:57,220

final INT and here I can say let's actually capitalize it like this is actually our constant.



151

00:10:57,230 --> 00:11:02,690

So it's a convention in dhaba to capitalize are constant names.



152

00:11:02,690 --> 00:11:14,990

So I can't say camera camera underly image underline request request code underline quote.



153

00:11:15,090 --> 00:11:15,680

Right.



154

00:11:15,790 --> 00:11:18,130

Assignment operator let's assign a unique value.



155

00:11:18,130 --> 00:11:18,970

This is very important.



156

00:11:18,980 --> 00:11:23,530

We must assign a unique value a unique integer value to this constant.



157

00:11:23,530 --> 00:11:25,950

So 1000 is unique here right.



158

00:11:25,960 --> 00:11:33,660

Let's scroll down here and now for the second argument of the Smurfette I can say camera image request



159

00:11:33,670 --> 00:11:34,230

the.



160

00:11:34,360 --> 00:11:35,650

That's it.



161

00:11:35,650 --> 00:11:42,680

So now that we have this statements so it is this statement says if the device has a camera or not.



162

00:11:42,790 --> 00:11:47,550

If this device has a camera then it's going to actually create an intent for the camera.



163

00:11:47,770 --> 00:11:51,410

It's going to actually allow the user to access the camera application and take a picture.



164

00:11:51,820 --> 00:11:57,660

And then if you have the Smurfette in order to open the activity the camera activity actually the camera



165

00:11:57,670 --> 00:12:00,970

intent and the and we pass this request card right.



166

00:12:01,150 --> 00:12:06,320

So what happens if the user if the user's device doesn't have a camera.



167

00:12:06,490 --> 00:12:08,590

We need to check for that condition too.



168

00:12:08,740 --> 00:12:16,860

So after the end increase the price of this statement I can actually create an ill statement so as that



169

00:12:16,900 --> 00:12:20,230

I just need to open and close this statement by using these curly braces.



170

00:12:20,230 --> 00:12:29,110

And here I can say toast does make text first we need to pass the context my activity that this comma.



171

00:12:29,320 --> 00:12:33,010

And for the sake of argument we need to pass the value that you want to show to the use that and here



172

00:12:33,010 --> 00:12:34,950

I can see your device.



173

00:12:36,680 --> 00:12:47,920

Does not have a camera does not have a camera write and here I just need to put a comma and then I just



174

00:12:47,920 --> 00:12:50,920

need to specify the duration of the message that I want to show to the.



175

00:12:50,920 --> 00:12:53,970

So it is going to be lenth short.



176

00:12:54,400 --> 00:12:56,680

And then that show.



177

00:12:57,120 --> 00:13:02,290

So you're already familiar with the syntax of actually showing a toast to the user.



178

00:13:02,290 --> 00:13:09,380

So now that we have these quotes here let's run the application and let's see what happens.



179

00:13:09,440 --> 00:13:11,260

Let me actually run the application now.



180

00:13:11,530 --> 00:13:14,160

So here you can see that our application is running.



181

00:13:14,470 --> 00:13:15,300

Right.



182

00:13:15,460 --> 00:13:17,050

And I'm going to get you to click on this.



183

00:13:17,080 --> 00:13:19,040

Take a picture button let's click on it.



184

00:13:19,390 --> 00:13:24,220

Now as you can see it's going I should ask their permission is going to ask us that this application



185

00:13:24,610 --> 00:13:29,130

is going to access the camera do you want to allow this app to access the camera.



186

00:13:29,200 --> 00:13:33,460

So here if I click on it now it's going to allow me to access the camera but I just need to click on



187

00:13:33,460 --> 00:13:34,620

it again take a picture.



188

00:13:34,630 --> 00:13:37,780

Now you can see that the camera app is actually open.



189

00:13:37,810 --> 00:13:39,980

And we can access the camera of the application.



190

00:13:40,090 --> 00:13:43,270

So we created an instant for this camera here.



191

00:13:43,330 --> 00:13:44,290

Right.



192

00:13:44,290 --> 00:13:49,990

And we call it the Start activity for results so it's going to open this activity for us and we passed



193

00:13:49,990 --> 00:13:50,760

the camera intent.



194

00:13:50,770 --> 00:13:53,350

And this is our request that we're going to use it later.



195

00:13:53,350 --> 00:13:55,290

Well we want to get this picture.



196

00:13:55,300 --> 00:13:59,160

So for example this is actually emulated right is not the real camera.



197

00:13:59,320 --> 00:14:00,710

This is actually an emulated terminal.



198

00:14:00,710 --> 00:14:03,360

So let's actually take the picture here.



199

00:14:03,400 --> 00:14:05,290

So another picture is taken.



200

00:14:05,320 --> 00:14:06,800

Now if I click on this.



201

00:14:06,820 --> 00:14:15,920

I can hear in order to actually accept this image you can see that nothing happened right.



202

00:14:15,990 --> 00:14:21,740

All you want that takes an image to appear here in place of this image inside this image.



203

00:14:21,830 --> 00:14:25,910

Because image view is a shell that holds the actual image.



204

00:14:26,060 --> 00:14:33,030

So you want this image you now hold that image that I have taken by using that camera.



205

00:14:33,380 --> 00:14:38,560

So how we can do that we need to overwrite this thot activity for results.



206

00:14:38,600 --> 00:14:43,030

And we need to actually provide an implementation for this method.



207

00:14:43,070 --> 00:14:52,160

So now let's actually scroll down here and you can see that we have these curly braces that are related



208

00:14:52,160 --> 00:14:53,380

to the cleanup effort.



209

00:14:53,390 --> 00:15:01,850

So after the curly brace of this method and before the end in curly brace of this main activity class



210

00:15:02,210 --> 00:15:08,610

I'm going to just step in here on activity resolved just typing here on activity and the autocomplete



211

00:15:08,660 --> 00:15:13,840

feature of Android studio is going to help you to just dismiss it on activity results or just a person



212

00:15:13,850 --> 00:15:15,000

until Chanute keyboard.



213

00:15:15,320 --> 00:15:17,280

So you can see this if it is actually protected.



214

00:15:17,300 --> 00:15:24,330

Protected means that only the subclasses of that of the activity class can actually use this method.



215

00:15:24,710 --> 00:15:27,730

So our main activity class is a subclass of activity.



216

00:15:27,740 --> 00:15:28,250

Right.



217

00:15:28,490 --> 00:15:32,880

So we can actually override this method on activity result we can see these arguments.



218

00:15:32,890 --> 00:15:39,010

Request code which I talk to you we talked about it previously in this story.



219

00:15:39,440 --> 00:15:42,550

We have the result code and we have the data.



220

00:15:42,620 --> 00:15:46,240

So now it is actually calling to support that an activity result here.



221

00:15:46,250 --> 00:15:49,220

This method is must be called after this line of code.



222

00:15:49,430 --> 00:15:57,670

Here I can say if we have this request code right so here I can see if request code is actually the



223

00:15:57,670 --> 00:16:05,140

same as the request code that was sent to the camera or intent here like camera image request code.



224

00:16:05,230 --> 00:16:13,690

So here I can say if request call is a call to camera with tropicals see camera image request code right.



225

00:16:13,730 --> 00:16:19,840

And we have this result here we want to check that if the intent is actually opened normally and we



226

00:16:19,840 --> 00:16:21,860

have no problems.



227

00:16:21,900 --> 00:16:24,620

So here I can just type in results code.



228

00:16:24,630 --> 00:16:28,150

This is very important that you refer to this result called another request card.



229

00:16:28,170 --> 00:16:28,930

OK.



230

00:16:28,980 --> 00:16:31,140

Is equal to result.



231

00:16:31,170 --> 00:16:31,860

OK.



232

00:16:32,070 --> 00:16:36,880

So here we are checking that everything is fine and nothing goes wrong here.



233

00:16:36,900 --> 00:16:37,390

Right.



234

00:16:37,440 --> 00:16:40,540

Let's go inside the curly curly braces of this statement.



235

00:16:40,830 --> 00:16:41,450

OK.



236

00:16:41,460 --> 00:16:45,880

And here first of all we need to get the bundle right.



237

00:16:46,140 --> 00:16:50,940

So bundle is going to be actually given to us by the state.



238

00:16:51,450 --> 00:16:53,780

You can see this data because of the intent.



239

00:16:53,940 --> 00:16:56,770

We received this data from an activity result.



240

00:16:56,820 --> 00:16:57,330

Right.



241

00:16:57,330 --> 00:17:03,080

So first of all let me tell you that when this activity resolved if it is going to be caught.



242

00:17:03,090 --> 00:17:07,730

So after this superdad and on activity result you're going to create a toast message.



243

00:17:07,730 --> 00:17:14,040

So here I can say toast that makes text first I need to pass the context which is going to be main activity



244

00:17:14,040 --> 00:17:21,370

that this write come up and really to pass the message so the message is going to be an activity a result



245

00:17:21,460 --> 00:17:23,570

on activity result.



246

00:17:24,780 --> 00:17:34,000

Is called right is called and I put a comma here and then I need to specify that actually the duration



247

00:17:34,180 --> 00:17:38,850

so length short that show.



248

00:17:38,890 --> 00:17:44,500

So let's run the application because I want to show you then decide if it is called Ventas an activity



249

00:17:44,500 --> 00:17:46,240

result is actually caught.



250

00:17:46,270 --> 00:17:48,640

Let me show you the emulator.



251

00:17:48,640 --> 00:17:51,110

So not our application is running on the simulator right.



252

00:17:51,310 --> 00:17:53,030

Let's click on take a picture.



253

00:17:53,320 --> 00:17:54,980

Let's take a picture now.



254

00:17:55,000 --> 00:17:59,410

And this really can accept as you can see it says unactivated result is called.



255

00:17:59,650 --> 00:18:05,560

So the unexpected result is called When we take a picture and we actually accept that.



256

00:18:05,560 --> 00:18:13,700

Now we can see that here when we back to this main activity here an activity result is called.



257

00:18:13,990 --> 00:18:20,590

So here is the place this non-activity result is actually is the place where we want to actually put



258

00:18:20,590 --> 00:18:26,560

that image that is taken by the user by using the camera of the device and put that image here inside



259

00:18:26,560 --> 00:18:28,330

this image view.



260

00:18:28,330 --> 00:18:32,520

So let's go back to our I should imagine if the glass inside is an activity result.



261

00:18:32,530 --> 00:18:38,020

So now we have this statement inside this if statement is the place to get that picture how we can get



262

00:18:38,020 --> 00:18:38,750

that picture.



263

00:18:38,800 --> 00:18:41,440

First we need to create of the level of the bundle.



264

00:18:41,560 --> 00:18:45,380

So bundle the name of our idea but it's going to be bundled assignment operator.



265

00:18:45,670 --> 00:18:48,690

So we have these data arguments right which is the intent.



266

00:18:48,730 --> 00:18:52,920

The intent is the intent of the camera intent actually right.



267

00:18:52,960 --> 00:18:58,180

So I can't say data that gets X through us semi-colon.



268

00:18:58,450 --> 00:19:03,940

So by using this to get extra Smurfette on this data which is of type intent you are going to access



269

00:19:04,160 --> 00:19:08,070

the data that is inside that intent to actually image.



270

00:19:08,080 --> 00:19:09,240

Right.



271

00:19:09,250 --> 00:19:13,060

So this intent which is its name is data right.



272

00:19:13,060 --> 00:19:19,510

These data holds that image that is taken by the user by calling this a good extra Asmaa if it does



273

00:19:19,660 --> 00:19:25,080

get stressed if it is going to return a bundle the return type of this method his bundle.



274

00:19:25,090 --> 00:19:30,610

And we can't assign the return type of this value that returns value of the Smurfette to this variable



275

00:19:30,610 --> 00:19:31,050

bundle.



276

00:19:31,060 --> 00:19:33,320

Let me show you the Android documentation.



277

00:19:33,880 --> 00:19:36,100

So here it is the android documentation right.



278

00:19:36,370 --> 00:19:41,880

And I actually searched for the intense class list inside the first part the sense for Internet and



279

00:19:41,960 --> 00:19:46,040

that app that intent on Android that content that the Internet actually.



280

00:19:46,050 --> 00:19:46,560

Right.



281

00:19:46,570 --> 00:19:51,550

So just like this one here and here let's search for the get extra effort.



282

00:19:51,550 --> 00:19:57,830

So in order to search for a specific Meffert in Andhra it's documentation if you are using a match point



283

00:19:57,840 --> 00:20:02,500

six you just need to hold down to the comments on your keyboard and the person that that key on your



284

00:20:02,500 --> 00:20:02,860

keyboard.



285

00:20:02,890 --> 00:20:05,250

And then just search for that specific method.



286

00:20:05,470 --> 00:20:10,120

If you are using of Indos machine you just need to hold down the control on your keyboard and then press



287

00:20:10,120 --> 00:20:13,750

on if your new keyboard in order to search for a specific effect.



288

00:20:13,750 --> 00:20:19,040

So here we are searching for the get extra MFL we can see that the return type of this for this bundle.



289

00:20:19,090 --> 00:20:26,080

And it says retrieves our map of extended data from the intent of map of extent that data up means it



290

00:20:26,080 --> 00:20:30,320

is going to be key value right map meaning key value here.



291

00:20:30,400 --> 00:20:30,890

Right.



292

00:20:30,950 --> 00:20:37,900

And it means that it's going to give us our map a key value of extended data from the Internet.



293

00:20:38,110 --> 00:20:43,270

So this get through as Meffert the return value the bundle doesn't throw anything about image or bitmap



294

00:20:43,880 --> 00:20:44,860

right.



295

00:20:44,950 --> 00:20:51,880

So we need to actually create a variable of type bitmap inside our main activity class and we can actually



296

00:20:51,880 --> 00:20:55,370

initialize our bitmap by using this map here.



297

00:20:55,780 --> 00:20:59,080

That is going to be returned from the get extra Smurfette.



298

00:20:59,230 --> 00:21:02,660

Let's go to the main activity class here.



299

00:21:02,760 --> 00:21:09,370

Now let's go let's scroll to the top and inside this class after this line of code that actually specifies



300

00:21:09,730 --> 00:21:16,340

the Chambre image Scott I can create a valuable private bitmap which is of the people with my right.



301

00:21:16,360 --> 00:21:18,300

The name is bitmapped semicolon.



302

00:21:18,520 --> 00:21:18,790

Right.



303

00:21:18,790 --> 00:21:21,230

I didn't initialize it I just declared this value.



304

00:21:21,250 --> 00:21:24,930

But let's scroll down here and let's go inside these unactivated result.



305

00:21:25,030 --> 00:21:33,490

Inside this if statement after getting the bundle here from the stator I can actually just initialize



306

00:21:33,550 --> 00:21:37,650

the bitmap how I can refer to this bitmap variable assignment operator.



307

00:21:37,930 --> 00:21:43,230

So I told you that the GET throws method doesn't know anything about bitmap or images.



308

00:21:43,410 --> 00:21:51,070

So you are 100 percent sure that there is actually a bitmap so remember that the image that is taken



309

00:21:51,070 --> 00:21:55,350

by the user by using the camera is actually going to be of type bitmap.



310

00:21:55,750 --> 00:21:58,530

So let's cast it to bitmap here.



311

00:21:59,000 --> 00:22:01,380

OK bitmap.



312

00:22:01,910 --> 00:22:09,940

And after this practice this year after this casting here I can refer to this bundle data just by using



313

00:22:09,940 --> 00:22:16,290

this gets Meffert on this bundle you're going to get the value by passing the key.



314

00:22:16,540 --> 00:22:18,900

So bypassing the key are going to get the value.



315

00:22:18,940 --> 00:22:21,630

So that's why it is called map right.



316

00:22:21,700 --> 00:22:25,380

Key value so get is going to be called on the.



317

00:22:25,720 --> 00:22:26,670

And bypassing.



318

00:22:26,710 --> 00:22:28,050

You can see that it says Key.



319

00:22:28,060 --> 00:22:28,570

Right.



320

00:22:28,570 --> 00:22:30,630

The pass the key is going to give us the value.



321

00:22:30,640 --> 00:22:32,850

So said this actually to send it like this Meffert.



322

00:22:33,010 --> 00:22:36,580

You can see that the arguments that we need to pass through this method is going to be off the screen



323

00:22:36,640 --> 00:22:37,460

and its name is key.



324

00:22:37,510 --> 00:22:38,900

So just put two coats here.



325

00:22:38,950 --> 00:22:42,010

The key is going to be data right.



326

00:22:42,250 --> 00:22:48,090

When the past Key data is going to give us the value it is going to be off the bitmap but that gets



327

00:22:48,090 --> 00:22:50,990

me if it doesn't know anything about the bitmap.



328

00:22:51,100 --> 00:22:57,220

But you are 100 percent sure it is going to be off the map so it just casts that two bitmap object and



329

00:22:57,250 --> 00:22:59,370

we initialized our bitmap area.



330

00:22:59,590 --> 00:23:07,200

Now after this line of code I can see IMT photo that set image bitmap bitmap.



331

00:23:07,440 --> 00:23:08,200

That's it.



332

00:23:08,230 --> 00:23:10,240

Let's run that application now.



333

00:23:10,630 --> 00:23:13,590

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



334

00:23:13,720 --> 00:23:15,190

Let's take a picture.



335

00:23:17,520 --> 00:23:22,020

Let's accept it's now you can see this image here.



336

00:23:22,020 --> 00:23:22,290

Right.



337

00:23:22,300 --> 00:23:23,710

An activity is all it is called.



338

00:23:23,740 --> 00:23:27,770

And here the image is actually put inside this image of you.



339

00:23:27,880 --> 00:23:28,630

That's it.



340

00:23:28,630 --> 00:23:31,560

If you want to can test this up on your actual device.



341

00:23:31,930 --> 00:23:38,530

So now in the next tutorial we're going to actually add another class in order to allow the user to



342

00:23:38,530 --> 00:23:45,430

use these search parties in order to colorful in order to make his image and truly colorful and add



343

00:23:45,460 --> 00:23:46,910

colors to this image.



344

00:23:47,020 --> 00:23:50,500

Red green and blue.



345

00:23:50,560 --> 00:23:53,560

So let's see how we can do that in the next story or so.



346

00:23:53,800 --> 00:23:54,780

Thank you very much for watching.



347

00:23:54,790 --> 00:23:59,690

If you have any questions about the concepts that I taught you so far please post the discussion in



348

00:23:59,690 --> 00:24:02,770

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