All language subtitles for 007 Linux - 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. So this is a video for
the Linux platform, so if you're running

Windows or a Mac, there's a separate video
in this section you can follow along

with and watch for those operating
systems. But if you're using Linux you're

in the right place. Now it's possible
that you might be running a 32-bit

version of Linux. If that's the case, I'd
seriously suggest you consider

installing a 64-bit version, the next
time you rebuild your computer.

Now a check is quite easy. You just open a
terminal,

and we just type uname space

- m, and that'll tell you whether
you're running a 64 or a 32 bit version.

You can see in my case it's reporting
x86_64, so that's clearly me

running a 64 bit version, but if you see
i 386 or i 686, that means you're

running a 32-bit version of Linux.
Android Studio now includes its own

installation of Java, but only ships with
a 64 bit version and that won't work on

a 32 bit Linux system. In June 2019,
Google announced that they're dropping

support, actually, for 32-bit systems. The
32-bit version of Android Studio will be

deprecated - in other words, no longer
available in December 2019 - and the

32-bit Android emulators, which you use
to run Android apps on your computer,

well they're also deprecated in June 2019. So you can find an announcement about that,

I'll just close the terminal window for
now. We'll open a new tab. I'll paste in

this link, which is available in the
resources section of this video,

and this blog post from Google
has got a lot more information about it.

So if you're using a 32-bit version of
Linux, do consider updating to a 64-bit version.

You can always dual boot if
you need a 32-bit version for some games.

Now distros like Ubuntu have now
committed to keeping the 32-bit

libraries on their 64-bit versions, so
most programs should continue to work on

a 64-bit version of Linux. So I can go
ahead now and install Linux, sorry,

install Android Studio I should say, by
doing a search for "install android studio",

and we want to go and visit the first
website that's got developer.android.com in the URL,

which is this top one. Click on
that, and basically, you want to make sure

that you are at developer.android.com so
you're basically downloading from the

official source. I'm gonna click on
download the latest version of Android Studio,

noting that for me, you see down the
bottom there it says 3.5 for Linux

64-bit 729 megabytes. It's 3.5 as of
the time I'm recording this video, the

latest version, but if you see a higher
version and it is released, which it is

on the screen, then you're good to go. Now
if you do go to download and you see

that it's a preview release, or a
pre-release, make sure you don't use that

version. It's highly recommended to use
the latest stable production release,

which in my case here, is on this page,
3.5 for Linux. Alright so if you're ready

now to do a fresh install of Android
Studio 3.5, which I am on Linux, let's

begin. So I'm going to click on the
download Android Studio button.

I'm going to agree to the terms and
conditions, download it for Linux

and I'm going to save that. That's saving
to my downloads folder because I'm in

Firefox.
Now while that's downloading you might

want to go and just have a look at
some information, and I'll just paste in

this link which is also available in the
resources section on this video.

There's some basic installation instructions
there for Linux as well,

and various flavors or distros of linux are actually
supported there with the information.

Now this page mentions some required
libraries you may need to install.

There's no date on this page that I can
see, anyway, and we found that these

libraries don't seem to be needed for
version 3.5 of Android Studio, because as

we're just seen, it's now fully 64-bit,
but make a note of the link and come

back here to install those libraries if
you get any problems with missing 32-bit libraries.

Now I'm installing on a
fresh Ubuntu 18.04 LTS version, and I

know that that doesn't have any of these
libraries installed and everything's worked fine,

and as we'll see in this
video it should go through and install again now.

Right, looking at our downloads over here, we can see that that's now finished.

I'm going to click on that now.

That opens an archive manager,

and we close down the browser because we've pretty much

finished with that for now. And I'm going to
click on extract and we need to choose

the location where I'm going to install
this. So I'm going to do it in my home folder,

so I'm just going to select home
up here, and click on extract.

Now you may want it to install it to slash USR slash
local instead. If you're comfortable with

Linux file permissions, do whatever you'd
normally do when installing software, but

if you're new to Linux, then extracting
to your home folder will work fine.

You can see that that's finished. I'm going to close
that down, and what we need to do now is

open another terminal session. I know I
closed it earlier in the video.

Now a shortcut to opening a terminal
session is ctrl alt T, so I'll do that

this time.
We'll bring this over to the middle of

the screen. We want to change our
directory into the folder we just

created, so cd~/ and
it's going to be a for android and that

should find it for us, and there's our
Android Studio folder, and if we do an ls there,

ls and have a look, we can see there's a
bin folder. We're going to click on, or

select rather, third time lucky, go into
that directory I should say. It's in the bin,

as you saw me do, and there's actually a
file in there called studio.sh, which we

want to invoke. We going to do that by
typing ./studio.sh

and that will invoke Android Studio. We
can ignore that warning message

there, and you see we're getting prompted
now to do an import. You can see it's

giving us the option to import settings
from a previous installation. This can

save you having to change all your
settings again, but as we're doing a

first time installation, I'm going to
leave it on the default, which is Do not

import settings and just click on OK.

Once that pops up I'm going to click on
Don't send to allow Google to collect

anonymous usage data. You can click on
send if you prefer but I'm clicking on

Don't send.

We're now starting the
Android, or have started the Android

Studio setup wizard, so I'm going to click
on Next. Now I'm going to choose a

Standard setup here. You can customize
Android Studio later if you want to.

Click on next. We've got a choice of
themes. Android studio comes with two,

as you can see. The standard one's called light, and I'm going to leave it on that one

because it comes up good in the
video, but you can choose darkula if

you prefer, which is better on the eyes
and, generally, what I would recommend for

developers. Choose one of those, click on
Next and then click on Next again,

because we've got some more downloading
to do at this point.

Now on this screen, before the download starts, it's popped up if your computer supports hardware virtualization.

Now if you're using Ubuntu or a distro based on it, then you

should already have KVM installed. If
you're not sure, click the link and

bookmark it, in case you need to review
the instructions later. And also keep in

mind there's a video later in this
section, on making sure that VTX is

enabled in your computer's bios, which
may be an issue preventing you from

using the accelerated performance mode.
Now we do need to have VTX enabled

because android emulators run as virtual
machines, and we need KVM working, so this'll

make more sense later. For me, you
can see that it has detected that, so I'm

just going to click on Finish at this
point.

Android Studio is now downloading a lot of the tools that it needs, and this includes the Android SDK software

development kit, which is actually quite
large. So it'll actually download about

1.5 gigabytes of related material files
etc at this point, and if you do get a

dialog asking you to retry at some point,
just click Retry. Sometimes the download

of some components fail for no apparent
reason and retrying it would generally

fix it. Sometimes it does take more than
one retry and I've got no idea why this

happens - busy network perhaps - but in any event, if

you do happen to see a Retry, just go
ahead and do that. Alright, so I'm going

to speed up the video now while the
components are actually downloaded here.

Well as you see, now that the components
have all been downloaded, we've got a

summary screen here. It is worth
scrolling up and down this if you

haven't been there while it's
downloading, just to make sure there's no errors.

As you can see in my case, there's no
errors showing and everything's up to date.

So I'm going to click on finish at this point,

and just size it up so we can see everything.
I'm going to close down the, actually I'll need to

leave that running for now. Now that
Android Studio's started it's a good idea

to set up a desktop launcher so you
don't have to keep running Android

Studio from the terminal. To do that
there's a built in option. Click on

Configure, and click on Create desktop
entry down here.

You've got the option to create it for all users if you want, but I'm not going to do that and I'm just

going to do it for the current user.
Click on OK. At this point we can now

exit Android Studio so I'm going to close
that down.

I'm also now going to exit the terminal
window,

and just to confirm that it's working, let's see if we can start the Android Studio,

you can see there's a desktop entry there. I'm just going to click on that now. We should see that

Android Studio will start for us.

And you
can see that we're good to go and Android

Studio is working successfully on our
Linux platform.

Alright, so that's Android Studio installed, and one other
thing I want to do before we finish the

video, is just make sure that KVM is
actually working on this system.

So I'll open up a terminal window again.

I'm going to type kvm ok, and you can see in

my system, because it's a brand new
install it's not installed, so I'm gonna

type sudo apt install cpu checker,

and we'll install that and then we'll
actually check to see if the hardware

virtualization is actually supported. We
did see that earlier in the video,

but kvm-ok now should work, and we'll
run this as root just to check it,

so sudo /usr/bin/kvm-ok.

Now my computer is showing at the moment

that it doesn't support KVM, and the
reason for that is this is a virtual

machine - it's actually running on my Mac,
actually, and I'm recording it that way.

So if you're installing this on a
regular computer, you'd find that you'd

have no dramas and everything would work
properly. That's a good way just to check

that you are running and if you find
that there's any issues with you getting

KVM extensions working, refer back to
that link that I talked about earlier in

the video, which hopefully you've
bookmarked, and you can find out more

information on how to go about actually
getting that working.

And just as another aside, if it's not working, search
online to see if your processor in your

computer supports VTX, or AMDV for an AMD
processor, then watch the later video to

enable it in your bios - that's the one that I
talked about. In the past, virtualization

was always enabled for AMD processors.
Recent motherboards may also need SVM to

be enabled, and that'll be in the
security settings in your bios.

Alright, so I'm going to end the video here. In
the next one we need to do some

configuration of Android Studio. The
steps at this point on now are largely

the same, regardless of which operating
system you're using, so I'll see you in

the next video which is titled Configure
Android SDK for all three platforms.

See you in the next video.
