1
00:00:08,840 --> 00:00:14,420
OK, so now that we have our user interface ready we're going to edit some properties attached to the
1

2
00:00:14,420 --> 00:00:22,550
user interface so let's say for example you click on the button over here on the right you have the
2

3
00:00:22,550 --> 00:00:26,990
attributes that you can modify let's change the I.D..
3

4
00:00:26,990 --> 00:00:29,740
for example let's call this button send.
4

5
00:00:29,740 --> 00:00:39,870
OK and let's call this edit text list item. OK.
5

6
00:00:41,900 --> 00:00:46,220
And just like that we've updated the I.D..
6

7
00:00:46,350 --> 00:00:47,940
Now what about the text.
7

8
00:00:48,120 --> 00:00:49,670
So let's see the button ...
8

9
00:00:53,580 --> 00:00:56,910
let's say we want to edit the text on the button.
9

10
00:00:56,910 --> 00:01:07,260
We want to make it say send, we can edit it from here and then you see it changes to send.
10

11
00:01:07,340 --> 00:01:12,740
Now another thing we could if you remember under values and strings.
11

12
00:01:12,740 --> 00:01:14,180
We have a list of strings
12

13
00:01:17,390 --> 00:01:21,750
what we can do is create a new String.
13

14
00:01:21,960 --> 00:01:33,370
Call it button text, set the value to send and change the reference in the button so rather than just
14

15
00:01:33,370 --> 00:01:38,070
putting the text directly we used string.
15

16
00:01:38,250 --> 00:01:43,620
It's just a bit cleaner like this, we're seeing both approaches 
16

17
00:01:43,620 --> 00:01:47,340
since developers tend to use both string and direct text
17

18
00:01:50,690 --> 00:01:58,780
and then with added text usually what you'd find is something like Help text rather than text.
18

19
00:01:58,780 --> 00:02:08,890
So let's say we click on the edit text let's remove the text and you can put hint. A hint will be for
19

20
00:02:08,890 --> 00:02:11,290
example enter list item here
20

21
00:02:14,990 --> 00:02:23,620
OK so now what happens when we run it again so you click on the rerun this just reinstalled the application
21

22
00:02:23,620 --> 00:02:32,890
on the device and here you can see now we have the text send and enter list item hint.
22

23
00:02:33,120 --> 00:02:33,550
OK.
23

24
00:02:34,440 --> 00:02:42,350
So it's straightforward enough and not too complicated again for reverse engineering it's not as important
24

25
00:02:42,470 --> 00:02:47,900
but you might come across cases where you need to understand what the malware is doing in terms of the
25

26
00:02:47,900 --> 00:02:50,550
user interface.
26

27
00:02:50,710 --> 00:02:54,490
Next we'll be attaching code to these UI elements.
27

28
00:02:54,490 --> 00:02:57,490
We'll see how the code interacts with the user interface.
