1

00:00:00,480 --> 00:00:06,700

So here as you can see I the access modifier of my my if it is public this method is static.



2

00:00:06,750 --> 00:00:07,270

OK.



3

00:00:07,470 --> 00:00:16,040

And the return type of this method is void and the name of my method is to verify that we can call someone



4

00:00:16,520 --> 00:00:20,810

and this this it actually accepts an argument of type activity.



5

00:00:20,970 --> 00:00:25,570

So here inside the Smurfit as you can see I have these lines of code.



6

00:00:25,890 --> 00:00:32,550

And first of all in line 20 as you can see here I have a variable of type integer and the name of this



7

00:00:32,550 --> 00:00:34,300

roundtable is permission.



8

00:00:34,590 --> 00:00:42,300

So here I actually referred to the name of this activity compact class activity compact that check self



9

00:00:42,300 --> 00:00:43,200

permission.



10

00:00:43,410 --> 00:00:49,560

Ok here I want to check whether I can access the call feature of the device or not check self permission



11

00:00:49,800 --> 00:00:52,340

and this method actually to accept two arguments.



12

00:00:52,440 --> 00:00:56,930

The first one is the activity that we have as an argument of our Meffert.



13

00:00:57,180 --> 00:01:03,300

And the second one is the permission that we are able to access manifest that permission the Khalfan.



14

00:01:03,500 --> 00:01:04,200

OK.



15

00:01:04,470 --> 00:01:06,970

And here I have an if statement.



16

00:01:07,020 --> 00:01:07,980

As you can see here.



17

00:01:08,130 --> 00:01:15,060

So if permission is not equal to package manager that permission granted.



18

00:01:15,180 --> 00:01:22,090

Ok so if we don't have the permission that the user would allow me to do that.



19

00:01:22,110 --> 00:01:22,600

OK.



20

00:01:22,770 --> 00:01:28,190

So if the user wouldn't allow me to access the call feature of the device.



21

00:01:28,230 --> 00:01:30,810

OK so this is the meaning of this piece of code here.



22

00:01:31,080 --> 00:01:35,400

If permission is not equal to package manager that permission granted.



23

00:01:35,520 --> 00:01:42,300

If we don't have access to that permission OK if the user wouldn't allow me to actually use the call



24

00:01:42,300 --> 00:01:43,770

feature of the device.



25

00:01:43,950 --> 00:01:46,220

And as you can see here I created the comment here.



26

00:01:46,320 --> 00:01:49,210

We don't have the permission to so prompt the user.



27

00:01:49,230 --> 00:01:51,520

So now I'm on to ask the user.



28

00:01:51,720 --> 00:01:52,190

OK.



29

00:01:52,380 --> 00:01:57,140

I want to ask the user to allow me to access the call feature of the device.



30

00:01:57,150 --> 00:01:57,690

OK.



31

00:01:57,750 --> 00:02:01,540

Activity compact that requires the permissions.



32

00:02:01,540 --> 00:02:08,220

So if it actually accepts free arguments the first one is the activity the second one is the permissions



33

00:02:08,310 --> 00:02:11,100

Aure that we want to actually ask the user.



34

00:02:11,100 --> 00:02:13,530

So here is the permissions Aure.



35

00:02:13,890 --> 00:02:16,540

And the first one is the request code.



36

00:02:16,650 --> 00:02:19,050

So I have this request called call here.



37

00:02:19,290 --> 00:02:20,910

OK.



38

00:02:21,030 --> 00:02:28,410

Now here inside our uncreate Smurfette I want to actually call the Smurfette verify that we can call



39

00:02:28,410 --> 00:02:29,060

someone.



40

00:02:29,160 --> 00:02:33,720

So here I can't just type in verify that they can call someone.



41

00:02:33,870 --> 00:02:41,820

And for the activity I can just type in here main activity that's this.



42

00:02:42,290 --> 00:02:47,490

OK so now let's actually run our project and see what happens.



43

00:02:47,490 --> 00:02:55,290

So now as you can see our application is running on this emulator here and here you can see now it is



44

00:02:55,290 --> 00:03:01,870

asking me that this allow app 45 to make and manage phone calls.



45

00:03:02,160 --> 00:03:09,790

So it is asking the user do you want to allow this application to make and manage phone calls.



46

00:03:09,990 --> 00:03:18,030

If I hit on allow here OK I can actually call someone if I hit on the night here I would not be able



47

00:03:18,030 --> 00:03:19,680

to call someone.



48

00:03:19,680 --> 00:03:28,030

So here I can actually select this allow here and now I can call someone in my application.



49

00:03:28,080 --> 00:03:32,850

So let's actually go back to my main activity here and it's actually at some more lines of code here



50

00:03:33,090 --> 00:03:38,610

because at the moment our application wouldn't do so much in here because if I click on these buttons



51

00:03:38,610 --> 00:03:42,480

here now you can see that we cannot actually do anything here.



52

00:03:42,480 --> 00:03:46,620

So we need to put those logic's inside our main activity class.



53

00:03:46,770 --> 00:03:51,840

So now I'm going to pasting some lines of code here and then I'm going to explain to you what's going



54

00:03:51,840 --> 00:03:52,950

on here.



55

00:03:52,980 --> 00:03:57,810

So as you can see here these are the lines of code that they actually place that inside this main activity



56

00:03:57,810 --> 00:03:58,360

class.



57

00:03:58,410 --> 00:03:59,010

OK.



58

00:03:59,010 --> 00:04:05,970

So first of all I actually declared the spot in BT and would give me bt between our search Google BT



59

00:04:05,970 --> 00:04:08,470

and Karl and Pythian access DeLaet.



60

00:04:08,490 --> 00:04:13,770

So inside these uncreate Mefford after this line of code here verified that they can't call someone



61

00:04:13,980 --> 00:04:19,970

here Ivonne to instantiate these but that I declared inside the main activity class.



62

00:04:19,980 --> 00:04:27,840

So here I can just typing PTEN or Penni you the assignment operator and here I can just actually pass



63

00:04:27,840 --> 00:04:38,730

this object to on to the button object find view by ID or that Id that PTEN open you the semicolon between



64

00:04:39,060 --> 00:04:42,380

search Google assignment operator here.



65

00:04:42,390 --> 00:04:50,190

I just need to cast this object to a button object find view by ID or that Id dot between Google search



66

00:04:50,280 --> 00:04:53,710

search Google semi-colon and are here.



67

00:04:53,730 --> 00:05:00,460

I just need to type in PTEN Col assignment operator Potin find.



68

00:05:00,470 --> 00:05:12,220

View by id artist Id dot PTEN Col semicolon between Access Dyott had assignment operator and here I



69

00:05:12,220 --> 00:05:21,070

need to cast this object to a button object find view by id r that ID that Pythian access dial pad semicolon.



70

00:05:21,170 --> 00:05:27,790

OK so now here I want to actually make these buttons a listener to the clicks of the user.



71

00:05:27,790 --> 00:05:32,720

OK so that our application would respond if the user touches one of these buttons.



72

00:05:32,740 --> 00:05:34,870

So here I can just type in between.



73

00:05:35,110 --> 00:05:43,630

Open you the me that set on click listener and here I need to pass the context main activity that this.



74

00:05:44,000 --> 00:05:45,820

OK so this is our context.



75

00:05:46,000 --> 00:05:52,400

And again I have this beauty and search Google so I can't just typing Pythia and search Google.



76

00:05:52,480 --> 00:05:55,270

That said Anchal listener.



77

00:05:55,820 --> 00:05:56,370

OK.



78

00:05:56,590 --> 00:06:06,920

Main activity that this and here again we have this beauty and called PTEN Karl data set on calculus



79

00:06:06,930 --> 00:06:18,480

and our main activity thought this here again we have this BT an Access style pad between access dial



80

00:06:18,480 --> 00:06:26,010

pad that said on click listener main activity that is OK.



81

00:06:26,310 --> 00:06:31,440

So here as you can see we have some errors and that's because of this interface we need to actually



82

00:06:31,470 --> 00:06:33,950

implement the unclick list in an interface.



83

00:06:33,960 --> 00:06:37,450

So here I can just typing after this compact activity here.



84

00:06:37,590 --> 00:06:45,160

I can't just type in implements view thoughts on click listener.



85

00:06:45,320 --> 00:06:50,930

So now again we have an error so we need to actually implement the uncle Smurfette in our main activity



86

00:06:50,930 --> 00:06:51,350

class.



87

00:06:51,350 --> 00:06:57,480

So here I can't just typing on Cliq and as you can see here is showing us this method here so I can



88

00:06:57,480 --> 00:07:04,280

just press enter key here and now we have this method here public Voyt and click method.



89

00:07:04,310 --> 00:07:09,980

So here as you can see if you have an argument of type view so the name of this argument is not good



90

00:07:10,070 --> 00:07:10,700

here.



91

00:07:10,700 --> 00:07:13,010

So I can't just change it to view.



92

00:07:13,180 --> 00:07:21,320

OK so here because I want to differentiate between clicking of these buttons here I just need to create



93

00:07:21,320 --> 00:07:26,560

a switch statement and I want to switch between the IDs of these buttons.



94

00:07:26,570 --> 00:07:30,180

So here I can just type in view that gets ID.



95

00:07:30,470 --> 00:07:30,930

OK.



96

00:07:31,100 --> 00:07:35,090

And then I need to actually open and close this switch statement.



97

00:07:35,090 --> 00:07:40,910

So here I can just type in our thought Id dot between open you'd see me.



98

00:07:41,060 --> 00:07:48,780

So if the user clicks or touches that BT and the button here I have this logic here.



99

00:07:48,890 --> 00:07:53,180

So here I actually forgot to put the case statement here.



100

00:07:53,180 --> 00:08:00,530

Case r that ID that Pythian open Eudemus So if the user clicks on a BT and open you me then it's going



101

00:08:00,530 --> 00:08:01,350

to respond.



102

00:08:01,520 --> 00:08:02,860

We have other cases too.



103

00:08:02,870 --> 00:08:08,660

So case are thought Id that Google search BT and search Google.



104

00:08:08,900 --> 00:08:11,630

OK colon break.



105

00:08:12,320 --> 00:08:18,550

And we have another case case are that Id dot PTEN.



106

00:08:18,770 --> 00:08:29,480

Carl Sullivan here as you can see Colan break case Artaud already thought between access they L-pad



107

00:08:29,870 --> 00:08:31,640

colon break.



108

00:08:32,210 --> 00:08:36,110

So here I want to put the logic here for these patents.



109

00:08:36,170 --> 00:08:40,970

So for this are BT and open to me here I want to paste in some lines of code here and then I'm going



110

00:08:40,970 --> 00:08:43,330

to explain to you what's going on here.



111

00:08:43,340 --> 00:08:47,820

So as you can see here these are the lines of code that I actually pasted here.



112

00:08:47,840 --> 00:08:52,830

First of all I created an object of type intent and the name of this object is intent.



113

00:08:52,850 --> 00:08:55,190

And here I put an assignment operator.



114

00:08:55,190 --> 00:09:02,210

So here I want to instantiate this intent object new intent and inside the prentices I want to specify



115

00:09:02,210 --> 00:09:05,650

that what that what would I want to do with this intent.



116

00:09:05,660 --> 00:09:12,230

So I want this intense tragedy open of a browser and then go straight ahead to Eudemus dot com.



117

00:09:12,320 --> 00:09:12,880

OK.



118

00:09:12,890 --> 00:09:18,920

So in order to do that job I need to actually call this intent that action view OK I want to actually



119

00:09:18,920 --> 00:09:22,860

open up a website in a web browser in my device.



120

00:09:22,940 --> 00:09:25,510

So I need to call this intent that action view.



121

00:09:25,970 --> 00:09:32,120

And here in the second line in line 81 as you can see we have this intent object that said data.



122

00:09:32,120 --> 00:09:34,740

So here I want to I need to actually specify the data.



123

00:09:34,760 --> 00:09:35,270

OK.



124

00:09:35,420 --> 00:09:36,480

You are.



125

00:09:36,750 --> 00:09:37,220

OK.



126

00:09:37,310 --> 00:09:39,740

I call this you or I class that parse.



127

00:09:39,800 --> 00:09:44,420

Hush TTP dot hostilely colon slash slash.



128

00:09:44,480 --> 00:09:47,400

W w w dot you see me dot com.



129

00:09:47,420 --> 00:09:48,100

OK.



130

00:09:48,110 --> 00:09:53,870

And here as you can see I call this Meffert start activity intent.



131

00:09:53,870 --> 00:09:56,660

So it's actually on our project and see what happens.



132

00:09:56,660 --> 00:10:01,240

So now as you can see our application is running on this emulator here.



133

00:10:01,340 --> 00:10:05,540

So if I actually click on this button here let's open you with me that's come let's see what happens.



134

00:10:07,210 --> 00:10:11,520

And as you can see it's now opening to you to me datacom for me.



135

00:10:11,640 --> 00:10:11,930

OK.



136

00:10:11,930 --> 00:10:14,380

In my web browser.



137

00:10:14,570 --> 00:10:17,420

So he had to be 10 cities Eudemus dot com.



138

00:10:17,570 --> 00:10:18,130

OK.



139

00:10:19,050 --> 00:10:21,110

So hopefully that makes sense.



140

00:10:21,300 --> 00:10:24,090

So let's us actually click on the back button here.



141

00:10:24,120 --> 00:10:26,550

Now I want to actually search the Google.



142

00:10:26,730 --> 00:10:28,460

So let's actually put that logic here.



143

00:10:28,500 --> 00:10:32,100

In this case statement here between search Google.



144

00:10:32,100 --> 00:10:34,770

So here I am able to actually paste in some lines of code.



145

00:10:34,800 --> 00:10:39,090

So as you can see here these are the lines of code that I actually paste that here.



146

00:10:39,090 --> 00:10:45,180

First of all again I actually created an object of type intent and the name of this object is intent



147

00:10:45,270 --> 00:10:47,250

to assignment operator.



148

00:10:47,250 --> 00:10:53,530

So here I am instantiating this intent object and inside the prentices because I want to actually search



149

00:10:53,550 --> 00:10:54,200

the verb.



150

00:10:54,360 --> 00:10:57,190

I actually called intent that action a web search.



151

00:10:57,300 --> 00:10:57,910

OK.



152

00:10:58,230 --> 00:11:01,570

And here I have this intent to object that set data.



153

00:11:01,800 --> 00:11:03,730

You are right that parse.



154

00:11:03,930 --> 00:11:08,820

And instead of double quotes I just typed in hushed ETP colon slash slash.



155

00:11:09,000 --> 00:11:11,350

W w w dot Google dot com.



156

00:11:11,480 --> 00:11:12,120

OK.



157

00:11:12,150 --> 00:11:16,410

And here I call this my first start activity intent too.



158

00:11:16,520 --> 00:11:19,080

So let's run our project and see what happens.



159

00:11:19,080 --> 00:11:24,710

So now as you can see our application is running Andi's emulator.



160

00:11:24,840 --> 00:11:25,580

OK.



161

00:11:25,950 --> 00:11:28,810

And here as you can see I want to actually click on this.



162

00:11:28,830 --> 00:11:31,040

Let's search the Google.



163

00:11:31,380 --> 00:11:37,120

And now as you can see it opened the website and now I can actually search the google here.



164

00:11:37,410 --> 00:11:38,210

OK.



165

00:11:38,730 --> 00:11:40,270

As you can see here.



166

00:11:40,410 --> 00:11:42,380

So hopefully that makes sense.



167

00:11:42,380 --> 00:11:47,650

So let me actually click on dispatch button here and here I want to call someone.



168

00:11:47,700 --> 00:11:49,590

Ok this is very important.



169

00:11:49,590 --> 00:11:54,850

So let's actually go back to our main activity class and put that logic here end card.



170

00:11:54,990 --> 00:12:00,330

So here I'm going to paste in some lines of code and then I'm going to explain to you what's going on



171

00:12:00,330 --> 00:12:01,290

here.



172

00:12:01,320 --> 00:12:07,440

So as you can see here these are the lines of code that I actually paste that here and here as you can



173

00:12:07,440 --> 00:12:12,280

see I created an if statement if context compact.



174

00:12:12,370 --> 00:12:12,640

OK.



175

00:12:12,660 --> 00:12:14,500

That takes self permission.



176

00:12:14,770 --> 00:12:15,080

OK.



177

00:12:15,090 --> 00:12:20,250

Because I want to actually call someone we need to first ask the user of whether they would allow me



178

00:12:20,550 --> 00:12:24,260

whether they would allow the application or to call someone or not.



179

00:12:24,270 --> 00:12:24,770

OK.



180

00:12:25,050 --> 00:12:28,170

If context compact that check self permission.



181

00:12:28,170 --> 00:12:33,800

So here we need to actually for the first argument Vini to specify this the context.



182

00:12:33,810 --> 00:12:40,530

So I could just type in main activity that is OK for this and here for the sake of argument we need



183

00:12:40,530 --> 00:12:44,370

to specify the permission that we want to actually access.



184

00:12:44,420 --> 00:12:48,690

OK manifest that permission does Carl form.



185

00:12:48,930 --> 00:12:49,620

OK.



186

00:12:49,890 --> 00:12:53,460

As you can see here manifest that permission that Khalfan.



187

00:12:53,460 --> 00:13:00,010

So if this permission is not equal to package manager that permission granted OK.



188

00:13:00,210 --> 00:13:08,240

If the user if the user didn't allow me to access the Khalfan feature of my device of their device OK.



189

00:13:08,580 --> 00:13:16,050

If my application is not allowed to access the call a feature of the device.



190

00:13:16,080 --> 00:13:16,350

OK.



191

00:13:16,350 --> 00:13:23,460

If the user didn't allow me to access the card feature here I want to ask them again activity compacts



192

00:13:23,760 --> 00:13:25,760

that request permissions first.



193

00:13:25,760 --> 00:13:31,730

Again I any to specify the context for here instead of this I could just type in main activity that



194

00:13:31,780 --> 00:13:35,860

this and for the second argument we need to specify the permissions.



195

00:13:35,940 --> 00:13:36,960

News strange.



196

00:13:37,020 --> 00:13:42,780

And here as you can see I have an array of type strange object as you can see I created an array of



197

00:13:42,780 --> 00:13:50,040

string object and inside that array I have this value manifest that permission that Khalfan and for



198

00:13:50,040 --> 00:13:53,670

the first argument we need to specify the request code card.



199

00:13:54,300 --> 00:13:55,390

As you can see here.



200

00:13:55,680 --> 00:14:01,590

So here I actually ask the user whether they would allow me to access the call feature of the device



201

00:14:01,620 --> 00:14:02,350

or not.



202

00:14:02,580 --> 00:14:03,100

OK.



203

00:14:03,180 --> 00:14:08,080

If they would allow me then I am allowed to actually access that feature.



204

00:14:08,250 --> 00:14:11,080

So here I have an else statement.



205

00:14:11,100 --> 00:14:16,320

If so if the user doesn't allow me to access the call feature OK then it's going to actually execute



206

00:14:16,320 --> 00:14:17,340

this line of code here.



207

00:14:17,460 --> 00:14:24,940

But if I have permission to access the call feature then it's going to execute this else statement.



208

00:14:24,960 --> 00:14:25,420

OK.



209

00:14:25,560 --> 00:14:32,010

Intent intent free Neil intent intent that action card.



210

00:14:32,250 --> 00:14:32,940

OK.



211

00:14:33,120 --> 00:14:34,910

So here this is the action card.



212

00:14:35,220 --> 00:14:40,490

And here again I referred to the name of this object intent free that said they tell you outright that



213

00:14:40,530 --> 00:14:42,980

parts and inside the double quotes.



214

00:14:43,060 --> 00:14:47,280

I just need to specify the number that you want to call.



215

00:14:47,290 --> 00:14:49,750

OK the phone number that I want to call.



216

00:14:49,750 --> 00:14:54,280

So here I just need to put this tell here tell call in.



217

00:14:54,300 --> 00:14:56,740

So this is an important Tell call in.



218

00:14:56,820 --> 00:15:00,660

And here it is going to be the phone number that you want to call.



219

00:15:01,040 --> 00:15:05,650

And here as you can see I call this my fifth start activity intensively.



220

00:15:05,940 --> 00:15:08,790

So let's run our project and see what happens.



221

00:15:08,790 --> 00:15:13,330

So here as you can see our application is running on this emulator here.



222

00:15:13,470 --> 00:15:18,260

So now I want to actually call someone let's So here let's actually click on this button here.



223

00:15:18,460 --> 00:15:20,620

Let's call someone.



224

00:15:20,980 --> 00:15:24,920

And now as you can see I am calling someone with this number.



225

00:15:25,240 --> 00:15:25,730

OK.



226

00:15:25,840 --> 00:15:28,080

So hopefully that makes sense.



227

00:15:28,090 --> 00:15:30,780

And let's actually click on this back button here.



228

00:15:30,820 --> 00:15:33,640

So now I want to access the dial pad.



229

00:15:33,640 --> 00:15:34,150

OK.



230

00:15:34,300 --> 00:15:39,340

So let's actually go back to our main activity the java file here and let's actually put that logic



231

00:15:39,340 --> 00:15:41,780

here bt an access dial pad.



232

00:15:41,950 --> 00:15:46,330

So here I'm going on pasting some lines of code and then I'm going to explain to you what's going on



233

00:15:46,330 --> 00:15:46,980

here.



234

00:15:46,990 --> 00:15:51,540

So as you can see here these are the two lines of code that they actually paste that here.



235

00:15:51,790 --> 00:15:58,540

So here I created an object of type intent and the name of this intent is our intent for this intent



236

00:15:58,600 --> 00:16:00,900

object assignment operator.



237

00:16:00,910 --> 00:16:07,600

So here I actually instantiated this object new intent and in say The Apprentice's I specified that



238

00:16:07,650 --> 00:16:09,950

I want to access the actual Dayal.



239

00:16:10,050 --> 00:16:10,350

OK.



240

00:16:10,360 --> 00:16:11,370

Intent that action.



241

00:16:11,380 --> 00:16:17,210

Daniel and here I call the Smurfette starved activity intent forth.



242

00:16:17,260 --> 00:16:21,190

So now let's actually run our project and see what happens.



243

00:16:21,190 --> 00:16:26,160

So as you can see here now our application is running on this simulator here.



244

00:16:26,290 --> 00:16:28,600

Let's access that dial pad.



245

00:16:28,600 --> 00:16:35,830

So let's actually click on this button here and now as you can see I can actually access the dial pad



246

00:16:35,830 --> 00:16:36,600

here.



247

00:16:36,960 --> 00:16:37,550

OK.



248

00:16:38,620 --> 00:16:46,280

So here if I actually click on the spot in here now I can access the dial pad or do something else.



249

00:16:46,300 --> 00:16:49,620

As you can see here and call someone.



250

00:16:49,980 --> 00:16:50,490

OK.



251

00:16:51,400 --> 00:16:57,160

So hopefully that makes sense and I think that's enough for this tutorial.



252

00:16:57,160 --> 00:17:03,220

So if you have any questions please post the discussion in the course and then I'll do my best to answer



253

00:17:03,250 --> 00:17:04,430

all of your questions.



254

00:17:04,570 --> 00:17:08,330

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