All language subtitles for 005 Windows - Install Android Studio_en_US

In this video I'm going to show you how
to download and install Android Studio,

which is the program we're going to be
using to write our Android applications

in this course. Just a reminder that
this is the Windows video, so if you're

running a Mac or Linux machine, refer to
a separate video in this section where you

can follow along for the installation
instructions for those operating systems.

So moving forward, presuming you're on
Windows. At this point, I'm going to

assume you're running a 64-bit version
of Windows. There's a - swing over to this

link here on screen - and there's a link
to this in the resources section of this

video. The 32-bit Android studio has been
deprecated, meaning that it won't be

supported for much longer
by Google. So this blog post - again you

can find the link to in the resources
section - but it's not a bad thing because

using Android Studio on a 32-bit system
wasn't a good experience. And that's

because 32-bit versions of Windows have
limitations on the amount of RAM that

they can use. In fact only 3.5 gigabytes
of RAM can be addressed by 32-bit

versions of Windows; and that's really
going to make life hard for you as

an Android developer. Android Studio
really needs more memory to operate

effectively. So to check if you're
running a 64-bit or 32-bit version of

Windows, you just come down here to the
search window, you can either type 32 or

type "about", and that will bring you to
either about your PC or if you get this

opportunity and see if you have a 32 or
64-bit version they should both take you

to this about page, as you can see here.
Then under device specifications you can

see it says system type. Now this says
64-bit operating system, and that means

you've got a 64-bit installation and
you're good to go.

Otherwise it'll say 32-bit, and that
would obviously mean you're running a

32-bit installation of Windows. Ignore
the processor bit, on the right-hand

side, it's the Windows installation type
that we're after. So if your screen looks

like this one, and says 64-bit, keep
watching the video and follow along. But

if yours says 32-bit then you're
probably going to have problems with this

course with that version of Windows.
There is a version of Android studio

that I alluded to that you can install,
for a 32-bit version Windows, but that's

again not going to be supported for much
longer.

Good news is though that, unless you
bought your computer a really long time

ago, the chances are pretty high that
you've already got a 64-bit cpu

installed, even if you haven't
necessarily got a 64-bit version of

Windows. So if you really want to get
into Android development then I suggest

that you would install a 64-bit
operating system. Now you'll probably have

to pay to upgrade windows to 64-bit, but
another alternative you can also

consider is installing a Linux operating
system - such as Ubuntu. And you can dual

boot that on your Windows machine. And
that's a lot cheaper, and in fact it's

free. But obviously you need to invest
some time in learning a new operating

system, in that scenario. So moving
on now, I'm going to assume that you're

running a 64-bit version of Windows. The
next thing I want to do is check the CPU.

So while we're on this screen, you can
take a look at the processor, and note

that for me it says Intel but depending
on your computer you may see Intel or

another option such as AMD. So if the
processor is Intel, as mine is, then you're

good to go. However if the processor was
AMD then there's another step to

perform. And things are slightly
different because it's an AMD processor.

So in that scenario, if you do see AMD - if
and only if - you want to come down to the

bottom of the screen down here. I'm going
to type "turn windows" until we get this

option here to Turn Windows Features on
or off. Or you may need to go into

control panel and find that. And again, if
you're on an AMD processors only,

let's go down to the bottom here and
we're looking for Windows Hypervisor

Platform. And you can see the check box
is off for me, but what you'll need to do

if you're on an AMD is check that and
click OK.

Obviously I'm not going to do that,
because you can see that I'm running a

Intel CPU in my scenario. What will happen,
when you do that and you're running an

AMD CPU, it'll adjust windows, change some
settings, and probably require you to

reboot. So do that if you're on an AMD
CPU, and then come back to this point in

the video and continue on as per normal.
Alright, so in my case, again, I mentioned

that I'm on Intel so I'm going
to cancel that, close down this, and

we're now what we're going to do is go
back to the google search engine, and

we're going to install Android Studio.
So first things first we want to find

it and then the easiest thing to do is
just do a search for install android

studio. And you want to click the
first developer.android.com link here

you can see that one says studio install
which is correct. Come over here and click

on "Download the latest version of
Android Studio" and this should give you

straight away the released latest
version of Android studio. If there are

options to click over here where you can
download other options, a 32-bit version

and so forth that we don't recommend, but
we're not going to do any of that. I'm

gonna go back and obviously down here it
tells us that it's the windows 64-bit.

I'm going to click on that, I'm gonna
click on I've read and agree, click on

download Android studio for Windows. I'm
just going to run that when it's

finished, so while that's downloading
keep in mind that the 3.5 you see there

may be a higher number,
when you come to download that. And the

reason for that is Google, who own the
Android product, they release new

versions of Android Studio on a regular
basis. So it's very hard, because they

release so many updates a year, to keep
these installation videos updated. But

the good thing is that generally the
installation is very similar to what

we'll go through in this video. So if you
see a later version there, on the same

screen that I've got on now, then you can
just proceed and download that

newer version, and you're good to go.
Ok you can see we're just about done

here now. we'll let it run its security
scan, and then it'll probably ask us to

update something. What I'm gonna do is
just close down the browser, because we're

finished with it anyway, and you may or
may not see this pop up on screen. But

it's asking is do we want to allow this
app to make changes to your device. So

I'm going to select yes to that, and that
will continue the installation. Click on

Next. We're going to make sure both these
options are checked, the first one we can't

uncheck anyway. Make sure Android Virtual Device is checked, click on Next. We're

going to install to the default location,
Next, and click on Install. We'll let that go

ahead and complete. Ok, that's now
completed. We'll click on Next and we'll

click on Finish, noting the checkbox for
Start Android Studio is checked - and

that's obviously going to do just that.
You'll get this option if you haven't

installed Android studio on your
computer before. It's giving us the

option to load the settings, or a configuration, from another

installation. We haven't got one, we're
starting from fresh, so I'm just going to

click on OK. Next we've got a wizard
that's popped up. I'm gonna click on Next

here, and we'll come over and click
Custom. Next you got a choice of themes

here. I'm going to leave it on white as
the white background, because that comes

up better in videos, but you might want
to choose Darcula, which is usually, or

certainly something, that a lot of
students would prefer. Because it's a

little bit easier on the eyes. So choose
the one you like, click on Next. Here we

want to make sure that we've got
everything checked. However there are

some notes to keep in mind, or things to
keep in mind, about Intel HAXM. We

specifically do not want to install
Intel HAXM if you're running an AMD CPU

or processor. Now the reason for that is
that the HAXM, which is a product that

actually speeds up and come over here and check it; it tells the over there that

it enables a hardware-assisted
virtualization engine - basically speeds

up the Android app emulation. Now that's
been written by Intel, and what they've

done is specifically make it not work
with non Intel CPUs. So therefore it

makes no sense to install it if you're
on an AMD CPU - and in fact you'll get

errors. So make sure you deselect that if
you are not on an Intel CPU, for that

reason. In my case, I am on an Intel CPU as
we saw early in the video. I'm going to

check it, click on Next, and this will
only pop up obviously if you selected to

check the box for HAXM. This is the
amount of RAM in your computer you want

to dedicate to HAXM. again to speed up
your Android app emulation. It's usually

okay to just leave the default - in my
case it's suggesting two gigabytes of RAM.

As a general piece of advice, if you've
got less than 8 gigabytes of RAM total

on your computer, do some research and
see if your computer can be upgraded to

8 gigabytes or even better 16 gigabytes.
Memory is relatively cheap, and it will

make a big difference in the performance
of Android studio and the emulators etc.

But in terms of the RAM you've got on your
computer now, if you've got 8 gigabytes or

more of RAM in your computer, leave it as
the default that's been selected

automatically within by the Installer.
But if you've got less than 8 gigabytes

then you'll need to allocate less to HAXM. Depending

on just how much memory you've got in
your computer, you may need to reduce

that to one gigabyte or even 512
megabytes. So I'm going to go ahead and

continue the installation of HAXM
because probably the majority of

Windows computers out there do have
Intel CPUs, and obviously we established

earlier in the video that mine has. So
I'm going to leave the defaults here, and

click on Next. Then we're going to click
on Finish and we're going to see that

there's a download going to take
place, so I'm just going to fast forward

this and we'll come back when it's
reached the next step.

Okay so the installation's continued.
You're now automatically being prompted to

allow this app to make changes to
devices. And this is because I've

selected HAXM, so you may not see this.
And if it comes up with a pop up, just click

on Yes to windows command processor and it's actually going now you can see down

the bottom it's running the Intel HAXM
installer. And if you tried to do this on

an AMD machine with an AMD CPU, so
there's a processor, you won't get an

error. I'm just going to pop up on the
screen what that will look like.

You can see, in my case, it was
successfully installed. Now there can be

reasons why the HAXM installation will
fail, even if you are on an Intel CPU, and

usually it's got to do with a BIOS
change on your computer that you need to

change. So if you do find that you're
going to error similar to the one you

can see on screen now, and you have got
an Intel CPU, then it might be worth

checking that VTX is enabled in your
computer's BIOS. And there's a video in

this section of the course with the
title "Enable VTX

in BIOS" which you can check out, which
should give you the information you need

to make that change in your computer. But
in my case you can see that I was

successful in installing HAXM, and in
fact the Android installation, so I

can click on Finish. At this point we've
done the basic installation of Android

Studio, so in the next video we're going
to look at configuring Android Studio. So

do note that I've got a Mac and a Linux
Android Studio install video coming up

in the next two videos, so skip those two
videos unless you want to also install

Android studio on a Mac or Linux machine.
What you want to do is now go to the

video titled "Configure Android SDK on
all three platforms" and there we'll go

through the configuration steps we need,
to get up and running in Android Studio.

So I'll see you in the next video.
