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. And we're going to be doing that on a Mac, so if you're running

a Windows or Linux machine there is a separate video for your operating

systems in this section of the course. And in that scenario I suggest you watch

the relevant video instead of this one. Alright, so first things first we can

install Android Studio by just doing a search in google for "install android

studio". We want to take the first developer.android.com link. When you

click on that, you click over here to download the latest version of Android

Studio, so this will generally show the latest version - you can see 3.5 for Mac.

So I'm going to click on that download Android studio I'm going to check the

checkbox that I agree to the conditions click on download I'm going to save that

in my downloads folder. So a new version is already available in what's called

the Canary channel, and what that means is that's a pre-release version for

testing. If it's released by the time you watch this video, and it's showed up

where it's currently showing 3.5 for me, then download the latest version. But at

this point this is the latest version and keep in mind that we do try and keep

these videos up to date, but with four or five new versions being released each

year, we can't update the course quickly enough. The good news is, though, that

generally if you choose the latest version, you'll be good to go. Alright so

I'm just going to wait for this download to complete, you can see it's nearly

finished, in the bottom left hand corner.

Once it's finished we need to open the dmg file, so I'm just going to click it

you may need to navigate to the folder where it's installed. I'm going to

close down the browser because we've finished with that now. I'm going to drag it over

to the Applications folder which is of course the standard way to install a Mac

application. Give that a moment to complete. We're going to close it down.

Now we can either navigate to the Applications folder or I can just do a

command space then type Android - just enough for Android studio. You can see

it's showing version 3.5. I'm going to press ENTER there and that should start

Android studio for us. Because it's the first time I've downloaded Android

studio, we get this pop up importantly you can see it says

developer.android.com so it's coming from the official site I'm going to

click on open. Now you may get a security error here. If that happens just go into

the system preferences and click on security click on general and then allow

it to run. In my case I haven't got that, so I'm just going to open it. As this is

the first time installation there's no previous settings to import, so I'm just

going to click on OK. You can see that Android studio is now

starting. Now we're going through a wizard at this point, so I want to click

on next here. I'm going to click on and choose custom Next. We've got a choice of

themes here, we can choose the light theme with the light background or Darcula

which has a dark background. That's generally better on the eyes, but

I'm going to leave it on light because that's good. and it looks better

on a video. Click on Next. We're going to choose make sure things everything's

checked. I'm going to check also Android Virtual Device, noting that Android

Studio the installation and setup wizard has automatically found the Android SDK

location or chosen an Android SDK location, and we'll talk more about that

in future videos. Cick on Next. Here we need to specify the amount of memory we're going

to allocate to HAXM. So what is HAXM? Well you can see that there's a link

there to refer to the Intel HAXM documentation for more information. What

it is is a program that's been written by Intel, the people who actually make

the Intel CPUs, and it speeds up the performance of the x86 emulators.

In other words it gives you the ability to run Android applications on your Mac

and it speeds them up by using this tool. So if you didn't have it Intel CPU you

wouldn't be able to do that, but all current Macs, and actually Mac's going

back quite some time, do have Intel CPUs as of the time I'm recording this, so we

won't have a problem. So the only choice here is to decide how much memory. Now

you can see the default here, because I've actually got 64 gig in my computer

choice of two gigabyte has been chosen automatically and if you've got more

than 8 gigabytes of RAM in your Mac I would suggest you leave it as the

default, which will probably be 2. But if you've got less, then you may need to

allocate less, depending on the amount of RAM you've actually got. In other

words, you might need to go down to one gigabyte or even 512 megabytes. Generally

I'd say that if you've got 8 gigabytes of RAM or more, just leave it on the

default and you've only got four gigabytes or something like that in your

Mac you may seriously want to consider adding more RAM to it. Ram is quite

inexpensive these days and it's highly recommended that you have 8 gigabytes or

more to get the most out of Android studio and using that on a Mac. Alright

so we'll leave it on the default as I mentioned, and click on Next. We've got a

list of things that are gonna download for us now. Click on Finish. Now the

reason it's doing more downloading here is that we actually downloaded the

Android Studio program, and that was the actual program that's running, now the

setup wizard and also the Android Studio product that you'll be using. But we're

now downloading the SDK, which is the software development kit, and that's

the actual software that enables you to write Android applications. So it's

actually separate and distinct from the Android Studio installer. That's why

we're doing another set of downloading here now. I'm going to pause the video,

and I'll come back once downloading is done. So you can see that we're getting

towards the end of the downloading and the unzipping now. Ok it's now running

the Intel HAXM installer, as you can see on screen. I need to enter my password

And again, HAXM is a tool that is going to make the Android emulator - which enables

you to run Android applications without having an Android phone on your computer -

enables that to run a lot faster than it ordinarily would without the HAXM

installer, so I was highly recommended to use that. Ok you can see that's now

finished. We can see silent installation has passed. At this point I

can click on Finish. We now see the welcome screen for Android Studio. In the

next video we'll look at configuring Android Studio, now that it's been

installed and the SDK has been downloaded. The steps from now on are

largely the same regardless of which operating system you're using, so

skip over the next video in the playlist, because that covers installing Android

Studio on a Linux machine, and go straight to the video titled "Configure

Android SDK on all three platforms" and we can continue the configuration. See

you in the next video.
