00:00:06,930 --> 00:00:09,250
So we just set up our first emulator.
1

2
00:00:09,300 --> 00:00:15,710
Now we're going to have a look at the tool called ADB Android Debug Bridge.
2

3
00:00:15,760 --> 00:00:20,830
So this is a tool that's used to communicate between the host machine that you're working on and the
3

4
00:00:20,830 --> 00:00:27,400
emulator or even the android device in the case that you're using an actual device during your analysis.
4

5
00:00:28,730 --> 00:00:35,300
So say you're working on a Linux, Mac or Windows machine and you have an emulator running or you connect
5

6
00:00:35,300 --> 00:00:37,080
your device through USB.
6

7
00:00:37,430 --> 00:00:41,930
Then you can use ADB to communicate between the machine and the Android system.
7

8
00:00:43,050 --> 00:00:51,420
Now ABD  is part of Android SDK so in the case of Linux the location of the SDK is usually under your
8

9
00:00:51,420 --> 00:00:56,190
home folder and inside you will see Android slash SDK.
9

10
00:00:56,850 --> 00:01:04,840
Similarly in Windows it will be under your user drive then Android slash SDK. Here you will see a list
10

11
00:01:04,840 --> 00:01:10,050
of directories and inside you'll see a directory called platform tools.
11

12
00:01:10,180 --> 00:01:18,900
And that's where you find ADB so to run that you're going to run ADB and for example Shell so when
12

13
00:01:18,900 --> 00:01:24,240
you run ADB shell it's going to take you to the shell of the Android device.
13

14
00:01:24,240 --> 00:01:30,030
So just like that we're in the environment of the Android device so within the shell you can do common
14

15
00:01:30,030 --> 00:01:34,600
Linux commands because as you know Android is based on Linux.
15

16
00:01:34,660 --> 00:01:42,580
So for example you can do 'ls' and it will list all the files, you can change directory etc.
16

17
00:01:42,830 --> 00:01:46,600
It's very similar to your Linux environment OK.
17

18
00:01:46,640 --> 00:01:50,310
And then you can just click exit to go back to your system.
18

19
00:01:50,520 --> 00:01:57,710
You can add ADB to your environment variables since this command will be used by many other tools.
19

20
00:01:58,130 --> 00:02:02,160
We'll go into the details of the ADB and its functionality later on.
20

21
00:02:02,390 --> 00:02:08,390
But here we just wanted to show that you don't really need to install it since it is part of the SDK.
21

22
00:02:08,390 --> 00:02:10,040
Also it is good to know the location.
