1

00:00:11,510 --> 00:00:17,290

High students in the City Hall you are going to go ahead and create our second Android application.



2

00:00:17,510 --> 00:00:22,220

So let's create an android studio project here.



3

00:00:22,220 --> 00:00:25,850

So the application name is going to be our second or app.



4

00:00:25,850 --> 00:00:27,870

Number two it doesn't really make a difference.



5

00:00:27,860 --> 00:00:29,680

You can name it whatever you want.



6

00:00:29,720 --> 00:00:34,030

You can specify the company domain package name and the product location here.



7

00:00:34,280 --> 00:00:36,690

So this actually can next.



8

00:00:36,950 --> 00:00:40,310

And here we need to specify the minimum STK for our application.



9

00:00:40,310 --> 00:00:45,200

So for a minimum masticated AP 16 Android 4.1 jelly bean.



10

00:00:45,320 --> 00:00:45,850

OK.



11

00:00:46,040 --> 00:00:49,670

So this is going to be the minimum version of Android.



12

00:00:49,930 --> 00:00:56,830

So you mean even British version of Android operating system that our application is allowed to run.



13

00:00:57,150 --> 00:00:57,590

OK.



14

00:00:57,740 --> 00:01:05,240

So the use of this device must have at least must have this version of Android Android 4.1 daily pain



15

00:01:05,630 --> 00:01:06,980

and phone and tablet.



16

00:01:07,190 --> 00:01:08,510

So that's good to connect.



17

00:01:08,540 --> 00:01:10,510

And here is basic activity.



18

00:01:10,520 --> 00:01:16,190

Just could be next here and activity name is main activity the lay out name is activity under the main



19

00:01:16,310 --> 00:01:19,980

title main activity and the many resources name is mine you underline me.



20

00:01:20,150 --> 00:01:23,980

So I suggest that you actually don't change any of these values here.



21

00:01:23,990 --> 00:01:29,400

Just click on finish so is going to create the project for us.



22

00:01:29,400 --> 00:01:31,570

So let's wait a little bit here.



23

00:01:37,490 --> 00:01:40,840

So as you can see it's actually Shumi other to be a little areas here.



24

00:01:40,850 --> 00:01:41,740

I just need to wait.



25

00:01:41,750 --> 00:01:45,190

As you can see at the bottom it says cradle built running.



26

00:01:45,470 --> 00:01:51,830

So now going can actually solve the problem for me is Carender here and now the errors are gone.



27

00:01:51,920 --> 00:01:57,490

But if the error actually exists here if the error is not gone for your specific Android.



28

00:01:57,550 --> 00:02:03,380

So you're just peeved at the top and then can you kind of rebuild project or you can actually close



29

00:02:03,380 --> 00:02:06,040

the Android studio and then open it again.



30

00:02:06,050 --> 00:02:10,640

So now let's actually look at these files here look at this file here.



31

00:02:10,670 --> 00:02:13,140

This is actually the contents underline minute example.



32

00:02:13,520 --> 00:02:18,800

And let's click on this activity underly minute exam so you can see that we have two exemplifies the



33

00:02:18,800 --> 00:02:21,180

first one is activity under limited example.



34

00:02:21,230 --> 00:02:24,240

And the second file is content under the last minute segment.



35

00:02:24,440 --> 00:02:31,070

And the reason is that we actually specify that we want to use basic activity when we created the application



36

00:02:31,070 --> 00:02:33,270

to use the basic activity as the template.



37

00:02:33,560 --> 00:02:37,970

So that's why it has actually created two XML files for us.



38

00:02:38,030 --> 00:02:41,890

So what's the difference Sillett sexually click this activity on delaminated exam.



39

00:02:41,900 --> 00:02:48,610

Here let's open it and you can see that we have this floating action button or I can select this filleting



40

00:02:48,620 --> 00:02:49,960

action button right.



41

00:02:49,970 --> 00:02:55,100

So let's go to this text up here at the bottom and we can see that as you can see at the right hand



42

00:02:55,100 --> 00:02:57,960

side we have this preview actually collapse this preview.



43

00:02:58,130 --> 00:03:01,380

So you can see this exemplifies this example McCourt's actually.



44

00:03:01,710 --> 00:03:04,020

And we can see these codes.



45

00:03:04,070 --> 00:03:07,760

And let's actually look at this line of Cahir in line number 24.



46

00:03:07,760 --> 00:03:13,530

Here it says include lay out the outside lay out the slash content underline make.



47

00:03:13,550 --> 00:03:18,620

So this means that this activity underlined means actually includes this content.



48

00:03:18,650 --> 00:03:20,730

Underland me right.



49

00:03:20,850 --> 00:03:27,150

So now inside this activity I main I can actually delete these floating action button.



50

00:03:27,200 --> 00:03:31,610

But inside this content underline minute example here at the top I can actually switch between these



51

00:03:31,610 --> 00:03:33,320

tabs between these taps.



52

00:03:33,380 --> 00:03:39,590

So if I actually switch the content on there I mean I mean there's a tab you can see that I cannot select



53

00:03:39,590 --> 00:03:41,470

this floating action button here.



54

00:03:41,780 --> 00:03:46,310

But if it actually Suroosh to activity Underland mean that ASML I consider exploiting action button



55

00:03:46,340 --> 00:03:47,790

and then I can delete it.



56

00:03:48,210 --> 00:03:50,370

But there is another difference.



57

00:03:50,510 --> 00:03:56,120

And is that in inside this activity underly I mean a decimal or you cannot selectees hello world takes



58

00:03:56,120 --> 00:04:02,590

you right this activity and eliminate examen actually holds includes this content.



59

00:04:02,600 --> 00:04:03,740

Underland minute segment.



60

00:04:03,890 --> 00:04:06,710

So if I you to go to this content under the last minute example.



61

00:04:06,830 --> 00:04:12,180

Now you can see that I can select this hello world view and then present delete key on my keyboard.



62

00:04:12,620 --> 00:04:17,930

So at that point if I actually go to a text that you can see that we have actually a relative lay out



63

00:04:17,930 --> 00:04:23,810

here I'll talk more about this layouts later but for now just know that the rel. out is going to actually



64

00:04:23,810 --> 00:04:26,610

position our user interface components.



65

00:04:26,660 --> 00:04:28,910

They're called the two other components.



66

00:04:28,980 --> 00:04:29,400

Right.



67

00:04:29,420 --> 00:04:33,340

So for example our insight is of widgets for this palette section.



68

00:04:33,340 --> 00:04:38,030

Here you can see that we have this with a spoiler so let's select this text view.



69

00:04:38,490 --> 00:04:42,460

And now let's drag this text view here inside this relatively.



70

00:04:42,500 --> 00:04:49,000

So you can see these arrows and it is actually pointing to other directions so this means that this



71

00:04:49,000 --> 00:04:55,990

takes you can be positioned according to these directions like for example down or actually decelerate.



72

00:04:55,990 --> 00:04:57,380

This takes you here again.



73

00:04:59,150 --> 00:05:02,200

And I see that I can actually put it wherever I want.



74

00:05:02,210 --> 00:05:07,310

So let's actually put it here at the center so you can see these dotted lines that is actually specifying



75

00:05:07,310 --> 00:05:12,210

that this textbook can be actually at the center horizontally and center vertical.



76

00:05:12,290 --> 00:05:17,960

Let's put it here and now I can actually give our text to the States view.



77

00:05:18,120 --> 00:05:21,450

So look at this property section here on the right hand side.



78

00:05:21,480 --> 00:05:23,540

We can give an ID to this text view.



79

00:05:23,550 --> 00:05:26,640

We can get actually a lay out with a layout height.



80

00:05:26,640 --> 00:05:28,770

I'll talk more about these later.



81

00:05:28,800 --> 00:05:33,380

So for now let's give a text to this things if you look at this text attribute here.



82

00:05:33,510 --> 00:05:39,540

But if you don't see if you cannot see these properties here at the bottom it says View all properties



83

00:05:39,690 --> 00:05:40,050

right.



84

00:05:40,080 --> 00:05:40,900

Just click on it.



85

00:05:41,070 --> 00:05:43,390

And here you can see all these properties here.



86

00:05:43,470 --> 00:05:44,120

Right.



87

00:05:44,250 --> 00:05:47,140

So now let's actually assessed for a specific property.



88

00:05:47,140 --> 00:05:53,310

So for example I want to search for the text property I select one of these properties here and now



89

00:05:53,370 --> 00:06:01,660

I can type in text and as he has said I can actually find this text property here and I can change the



90

00:06:01,660 --> 00:06:03,230

text of this takes view.



91

00:06:03,280 --> 00:06:11,530

So I just double click on this value and I can change it here so I can say put your text here for example



92

00:06:11,530 --> 00:06:17,070

put your text here and in person and help you and your keyboard.



93

00:06:17,100 --> 00:06:19,530

So I change to take the text of this text view.



94

00:06:19,740 --> 00:06:24,080

So let's actually increase the text size the font size of this text view.



95

00:06:24,090 --> 00:06:30,980

So again select one of these properties here and just search for text size attributes text size.



96

00:06:30,990 --> 00:06:33,540

So now we can see this text size attribute here.



97

00:06:33,540 --> 00:06:37,300

Just click on it and let's increase it to 18 s.p.



98

00:06:37,620 --> 00:06:40,400

Or I can actually change it to 24 s.p.



99

00:06:40,440 --> 00:06:47,390

So remember the s.p is actually used for giving for the size of our text inside our text.



100

00:06:47,490 --> 00:06:50,630

So always use espie for their font size.



101

00:06:50,640 --> 00:06:52,270

This is very important.



102

00:06:52,510 --> 00:06:57,720

And now I can actually also make this text view the text actually bold.



103

00:06:57,860 --> 00:06:58,340

OK.



104

00:06:58,350 --> 00:07:02,040

So just click on this text style so you can see that we have normal.



105

00:07:02,070 --> 00:07:02,740

It Halik.



106

00:07:02,750 --> 00:07:05,580

Now select this board right.



107

00:07:05,650 --> 00:07:09,730

I can actually check our unchecked is not normal a checkbox.



108

00:07:09,760 --> 00:07:12,970

And just check this board here so you can see this value here.



109

00:07:13,090 --> 00:07:14,570

Right.



110

00:07:14,850 --> 00:07:20,140

Now I can run our application and let's see what happens just at the top just click on this run button



111

00:07:20,170 --> 00:07:23,950

or display button and select one of these devices.



112

00:07:24,100 --> 00:07:26,320

And I just click on OK here.



113

00:07:26,410 --> 00:07:27,810

So let's wait.



114

00:07:27,910 --> 00:07:31,700

And by the way if you want to increase the font size of your Java code.



115

00:07:32,020 --> 00:07:34,920

So as you can see our application is not allowed to run.



116

00:07:34,960 --> 00:07:35,790

Why.



117

00:07:35,800 --> 00:07:41,840

Because in the activity under mentalism and if you remember we actually deleted this Flaten action button



118

00:07:41,910 --> 00:07:45,370

in and inside the main activity that Jobab filed class.



119

00:07:45,370 --> 00:07:48,010

So let's actually double click on this in activity of a fight.



120

00:07:48,010 --> 00:07:52,530

So if you can't find this tab here you just need to insert this view here and say this.



121

00:07:52,540 --> 00:07:59,110

Andrew to you here on the left hand side you just opened a folder and then opened this package was just



122

00:07:59,120 --> 00:08:02,770

sitting on this little triangle and that double clicked my inactivity fight.



123

00:08:02,800 --> 00:08:03,420

OK.



124

00:08:03,730 --> 00:08:08,080

And here in order to make this a job of course here a little bit wider Let's double click on this main



125

00:08:08,080 --> 00:08:09,250

activity that of a fight.



126

00:08:09,370 --> 00:08:10,610

So it is now wider.



127

00:08:10,840 --> 00:08:15,880

And as you can see if you have this piece of code here that is related to the floating action button



128

00:08:16,300 --> 00:08:18,580

we don't have to fill that in action button now.



129

00:08:18,700 --> 00:08:21,070

So this piece of code here is actually too redundant.



130

00:08:21,220 --> 00:08:24,240

And this piece of what is the cause of the error.



131

00:08:24,310 --> 00:08:26,880

This piece of code does not allow our application to run.



132

00:08:26,950 --> 00:08:30,350

So let's selected here inside this uncreate method.



133

00:08:30,450 --> 00:08:35,500

I just want to select this piece of code here that is actually related to the floating action button



134

00:08:35,830 --> 00:08:36,910

and deleted.



135

00:08:37,300 --> 00:08:38,080

Right.



136

00:08:38,140 --> 00:08:41,260

So make sure that you actually do not to delete the closing curly braces.



137

00:08:41,260 --> 00:08:42,980

This creates Meffert here.



138

00:08:43,420 --> 00:08:45,710

So now the error is solved.



139

00:08:45,760 --> 00:08:47,580

Let's run an application again.



140

00:08:48,040 --> 00:08:54,330

Let me show you the emulator let me increase the width and height of this emulator so that you can see



141

00:08:54,420 --> 00:08:55,080

better.



142

00:08:56,920 --> 00:08:58,150

So now let's wait.



143

00:08:58,150 --> 00:09:04,180

And by the way if you want to actually increase the size of your Java code here you just need to click



144

00:09:04,180 --> 00:09:06,760

on at the top just click an android studio.



145

00:09:06,790 --> 00:09:11,390

So if you are using a Windows machine you just need to click fight.



146

00:09:11,770 --> 00:09:13,410

And then click on settings.



147

00:09:13,600 --> 00:09:18,530

So if you are using a Mac just click on Android sudi at the top and then click on preferences.



148

00:09:18,790 --> 00:09:25,540

So now here opened the editor here by just clicking on this little triangle and then open our colors



149

00:09:25,570 --> 00:09:28,280

and fonts and then click on font.



150

00:09:28,630 --> 00:09:34,750

So here in order to actually increase the font size of our job codes we need to create a new scheme.



151

00:09:34,780 --> 00:09:37,670

So here you just need to click on Save As.



152

00:09:38,050 --> 00:09:40,840

And then you just need to give a unique name to your skin.



153

00:09:40,840 --> 00:09:49,570

For example my unique scheme right and then click on OK.



154

00:09:49,730 --> 00:09:55,560

So we actually created a new scheme and now I can increase the font size of my job of course.



155

00:09:55,580 --> 00:09:57,880

So currently it is now 22 right.



156

00:09:57,890 --> 00:10:01,940

I can easily see two for example 50 and then I can click on OK.



157

00:10:02,390 --> 00:10:08,930

So as you can see the full size of my Dovercourt now increased or you can actually change the theme



158

00:10:09,170 --> 00:10:10,250

of your Would you.



159

00:10:10,250 --> 00:10:14,390

So in order to do that you just need to click on at the top just click on Android studio preferences



160

00:10:15,350 --> 00:10:22,580

and an open editor and in the inside it has this critical general here and you can see that we have



161

00:10:22,580 --> 00:10:24,100

this appearance.



162

00:10:24,110 --> 00:10:24,530

OK.



163

00:10:24,650 --> 00:10:28,190

You can actually change these properties here.



164

00:10:28,280 --> 00:10:32,290

But let's actually click on these colors and fonts and click on general here.



165

00:10:32,300 --> 00:10:34,420

Instead these colors and fonts.



166

00:10:34,640 --> 00:10:41,720

And now I can actually change the theme of my application so I have default.



167

00:10:41,750 --> 00:10:45,470

So these are the things that I actually created in the past.



168

00:10:45,560 --> 00:10:48,890

I have to actually copy and all these other stuff.



169

00:10:48,920 --> 00:10:50,370

This is my new scheme.



170

00:10:50,420 --> 00:10:51,330

My unique scheme.



171

00:10:51,350 --> 00:10:56,860

So you can see that the font size increased both or you can actually make it bold as you can see here.



172

00:10:56,930 --> 00:11:02,870

You can make them Halik or bold so you can actually change this back and ankle.



173

00:11:02,870 --> 00:11:04,900

So for example if I select this you can see this.



174

00:11:04,910 --> 00:11:06,610

It says back in the late.



175

00:11:06,890 --> 00:11:13,730

And we can see the splash color if I click on it I can change the background color of my code.



176

00:11:13,730 --> 00:11:19,490

So for example I can select this right here at the bottom and I can actually change it to blue if I



177

00:11:19,490 --> 00:11:24,560

could kind of choose I can click on OK here at the bottom as you can see the background color here is



178

00:11:24,560 --> 00:11:25,530

now blue.



179

00:11:25,910 --> 00:11:28,440

If you want to change them I just need to again.



180

00:11:28,510 --> 00:11:31,770

I just need to go to preferences again and lose your preferences.



181

00:11:31,880 --> 00:11:37,000

And again if you are using a Windows machine you just need to click on file settings so preferences



182

00:11:37,400 --> 00:11:44,220

and again are just to go inside the editor colors and fonts and in general and here are for the packet.



183

00:11:44,270 --> 00:11:47,970

I can actually change the background color to for example green.



184

00:11:48,260 --> 00:11:51,150

If I click and choose Now the background color is green.



185

00:11:51,440 --> 00:11:55,300

So let's actually make it little black.



186

00:11:55,640 --> 00:12:02,910

So let's actually take his handler and then just drag it here at the bottom so that the back and color



187

00:12:02,910 --> 00:12:05,090

is going to be black and then click can choose.



188

00:12:05,100 --> 00:12:11,230

So now the background color is black and now or let's actually click on this once again.



189

00:12:11,250 --> 00:12:14,950

Let me actually decrease the font suit so that it is actually training free.



190

00:12:15,330 --> 00:12:16,350

Let's click on OK.



191

00:12:16,470 --> 00:12:20,330

So now we can see that the background color is black.



192

00:12:20,790 --> 00:12:25,610

And you can see that the font size of my double quotes is actually 23.



193

00:12:25,650 --> 00:12:27,300

I can actually change the text.



194

00:12:27,300 --> 00:12:32,290

So let's actually click on these preferences here and then go to font.



195

00:12:32,400 --> 00:12:36,080

And now I can click on this general so you can see this for Grant.



196

00:12:36,120 --> 00:12:36,750

Right.



197

00:12:36,810 --> 00:12:42,000

So I can't change this for foreground color through for example red literally can choose.



198

00:12:42,000 --> 00:12:42,840

And let's see what happens.



199

00:12:42,840 --> 00:12:46,640

You can see that the color of this text is now actually red.



200

00:12:46,680 --> 00:12:53,760

If I click on OK you can see now these colors here this red color for specific features.



201

00:12:53,760 --> 00:12:58,980

So let's actually go back to and look at the top and then click on preferences again.



202

00:12:59,610 --> 00:13:03,820

And let's actually change this color to for example to blue.



203

00:13:04,410 --> 00:13:07,400

And then click on Tues and then OK.



204

00:13:07,470 --> 00:13:09,330

So you can see now it is blue.



205

00:13:09,330 --> 00:13:13,240

Let's go to Andrew in studio again preferences.



206

00:13:13,320 --> 00:13:15,450

Let's change the color to white.



207

00:13:15,540 --> 00:13:20,810

So here at the bottom I can actually siliceous handle it and drag it to the top.



208

00:13:20,920 --> 00:13:26,280

And now I can just put this here this pointer at the center.



209

00:13:26,400 --> 00:13:28,310

And then you can just click and choose.



210

00:13:28,320 --> 00:13:31,450

So now the color is white right.



211

00:13:31,560 --> 00:13:34,110

So you can see this white color here.



212

00:13:34,110 --> 00:13:35,750

So hopefully that makes sense.



213

00:13:35,760 --> 00:13:40,680

And you can actually customize the font color the background color the foreground colors you can do



214

00:13:40,770 --> 00:13:42,980

anything with your Android studio.



215

00:13:43,320 --> 00:13:46,410

So let's let's actually let me show you the average video here.



216

00:13:46,460 --> 00:13:51,390

Now you can see that our application is running on the simulator and you can see this takes here at



217

00:13:51,390 --> 00:13:52,150

the center.



218

00:13:52,290 --> 00:13:53,880

Right.



219

00:13:53,910 --> 00:13:59,280

So I think that's enough for the whole deal in the next it's really going to continue building this



220

00:13:59,280 --> 00:14:00,320

application.



221

00:14:00,720 --> 00:14:06,750

And by the way I actually created this tutorial in order to update the original part 1 app.



222

00:14:06,780 --> 00:14:10,770

Number two section of the course of the Antrix studio of course.



223

00:14:10,770 --> 00:14:18,000

I am actually updating decors So please if you have any problems if you actually encounter any problems



224

00:14:18,240 --> 00:14:24,210

regarding Android studio and specifically its newest features please post the discussion in the course



225

00:14:24,660 --> 00:14:27,510

00:14:27,780 --> 00:14:28,850
