00:00:00,090 --> 00:00:02,860
Welcome to the age in minute application.

2
00:00:02,880 --> 00:00:09,150
So we're going to build a very basic application, which allows us to calculate the age in minutes,

3
00:00:09,150 --> 00:00:15,210
so we just enter our birthday and then it will give us how many minutes old we are.

4
00:00:15,420 --> 00:00:19,530
Of course, it's not going to be precise by the minute, but this is going to be precise by the day,

5
00:00:19,530 --> 00:00:20,190
so to speak.

6
00:00:20,190 --> 00:00:24,000
So whatever day we chose, that's how precise it will be.

7
00:00:24,470 --> 00:00:24,870
OK?

8
00:00:25,080 --> 00:00:32,130
And then we will see how to create a UI so how we can build our own user interface so that it looks

9
00:00:32,340 --> 00:00:33,720
like we want it to look.

10
00:00:34,140 --> 00:00:39,770
Then we will look at using text views and buttons, of course, which are part of the UI.

11
00:00:39,780 --> 00:00:45,300
So how we can display text, how we can press buttons, then also how to use dialogue.

12
00:00:45,300 --> 00:00:51,970
So to create our own dialogue, so to speak, which we can then use in order to select the date.

13
00:00:52,050 --> 00:00:58,410
So we're going to use to date picker dialogue and we can then get that date and do calculations with

14
00:00:58,410 --> 00:00:58,530
it.

15
00:00:58,740 --> 00:01:03,240
And then finally, we will display the result of those calculations.

16
00:01:03,570 --> 00:01:03,930
All right.

17
00:01:03,930 --> 00:01:09,480
So we are going to use a bunch of built in classes, which is really helpful because we don't want to

18
00:01:09,480 --> 00:01:11,130
write all of the code ourselves.

19
00:01:11,400 --> 00:01:15,330
We want to keep it as simple as possible, and that's exactly what we will do.

20
00:01:15,850 --> 00:01:16,230
OK.

21
00:01:16,350 --> 00:01:18,090
So I hope you enjoy this chapter.

22
00:01:18,330 --> 00:01:22,140
It's really just the beginning, but at least it's something cool that you can already share with your

23
00:01:22,140 --> 00:01:28,440
friends and you can play around with, and it's your first steps towards becoming a real Android developer.

24
00:01:28,860 --> 00:01:31,020
All right, so see you in the next video.
