1 00:00:01,139 --> 00:00:13,580 Well, today we are going to explain App Inventor, which is a project, it's a Google's project 2 00:00:13,580 --> 00:00:20,780 to create apps, applications for smartphones. 3 00:00:20,780 --> 00:00:28,780 It is really easy to do it using this application. 4 00:00:28,780 --> 00:00:38,380 The main problem, you can have another problem, but not the use of the application itself. 5 00:00:38,380 --> 00:00:51,659 So firstly, the App Inventor is online, so you click App Inventor Meet Edu, which is 6 00:00:51,659 --> 00:00:58,500 the address of App Inventor, and here you are, this is the project. 7 00:00:58,500 --> 00:01:11,799 You can inform different things, what is the app inventor, the sponsors, or if you want 8 00:01:11,799 --> 00:01:24,739 to donors, because the last link, it can be also used in other forms and Apple's devices. 9 00:01:24,739 --> 00:01:26,739 stories news 10 00:01:27,079 --> 00:01:29,079 etc resources 11 00:01:29,299 --> 00:01:35,739 so if you want to get this if you want to create apps, it's very easy, but because 12 00:01:36,560 --> 00:01:38,760 the only thing that you really 13 00:01:39,579 --> 00:01:42,420 Need is and it's more for my smart 14 00:01:44,120 --> 00:01:48,000 Smartphone and also a Google account 15 00:01:48,859 --> 00:01:51,700 so with your Google account you can 16 00:01:52,700 --> 00:01:54,700 log in a 17 00:01:54,739 --> 00:02:11,370 into AppEventor. The appearance of AppEventor is, as you can see, here you have a list of 18 00:02:11,370 --> 00:02:24,169 your different projects, projects that you have here, you can get the list of your projects 19 00:02:24,169 --> 00:02:34,770 Or connect with something that we will explain later. 20 00:02:34,770 --> 00:02:41,030 My projects also can go to the gallery and if you want, at the beginning, it could be 21 00:02:41,030 --> 00:02:48,569 a good strategy to look and to see other applications. 22 00:02:48,569 --> 00:03:03,159 For example, here you have a very interesting one, very simple and very interesting. 23 00:03:03,159 --> 00:03:11,539 As you can see, it's just only a cat, which name is Kitty, and if you push in the screen 24 00:03:11,539 --> 00:03:20,199 of a button, which is indeed the cat, if you push the screen in your mobile phone, it's 25 00:03:20,199 --> 00:03:21,199 set now. 26 00:03:21,199 --> 00:03:23,000 It's very easy. 27 00:03:23,000 --> 00:03:28,979 So here, the blocks, it's very easy to know. 28 00:03:28,979 --> 00:03:36,199 You can also move your mobile phone and it also can do the same. 29 00:03:36,199 --> 00:03:48,039 So it's a good strategy if you want to start doing something like this, something that 30 00:03:48,039 --> 00:04:05,060 what other people have already created with App Inventor. 31 00:04:05,060 --> 00:04:10,060 You also have helps, if you want, in the gallery. 32 00:04:10,060 --> 00:04:17,060 You have here a guide that you can also use, report, 33 00:04:17,060 --> 00:04:25,500 And you can change, for example, the language here, if you want, if you prefer in Spanish. 34 00:04:25,500 --> 00:04:34,720 I think I keep in English. 35 00:04:34,720 --> 00:04:44,199 So supposing you want to create a new app, what would you do? 36 00:04:44,199 --> 00:04:51,459 Well, very easy, firstly, we are going to start a new project. 37 00:04:51,459 --> 00:05:06,639 give it a name for example calculator calculator can be a machine calculator 38 00:05:06,639 --> 00:05:17,180 can be a machine that with two two numbers calculate its art it what you 39 00:05:17,180 --> 00:05:24,300 want for example so here you are the screen you know you you need to design 40 00:05:24,300 --> 00:05:32,220 the layout of the screen. So to do that you have the layout and it can be horizontal arrangement 41 00:05:32,220 --> 00:05:41,180 or scroll arrangement or what you want. My advice is a vertical arrangement. 42 00:05:42,459 --> 00:05:47,660 So now you have in your screen a vertical arrangement 43 00:05:47,660 --> 00:06:05,370 and here fill pattern and also fill pattern you can also if you want as you can see here 44 00:06:05,370 --> 00:06:15,370 and imagine or in any case you can change the background color, for example, orange. 45 00:06:15,370 --> 00:06:28,370 Well, now we have to choose the different elements in your screen. 46 00:06:28,370 --> 00:06:45,370 So, for example, first a label. So label, on the right you have the different characteristics of label. 47 00:06:45,370 --> 00:07:14,470 So Label, for example, we can change the height, no, height, no, first the width, width, width pattern, and obviously the content of the label. 48 00:07:14,470 --> 00:07:46,839 In this case, we can say, give me a number, and change the test color, the alignment of the test color, yeah, give me a number. 49 00:07:46,839 --> 00:08:07,910 And then, for example, a text box, for example, this box is filled pattern-wise, and give 50 00:08:07,910 --> 00:09:03,669 me another number, it's another label, and another text box. 51 00:09:03,669 --> 00:10:22,769 So now for example we also can add a button, push, well, for example. 52 00:10:22,769 --> 00:11:54,600 And now, one level, another level, another level, and you can, a text box here, and the 53 00:11:54,600 --> 00:12:34,620 text, for example, this one is, it's addiction, well, delete one, and this level also, addiction 54 00:12:34,620 --> 00:12:54,970 for example and the the multiplication there's only addiction and multiplication so 55 00:12:55,690 --> 00:13:08,509 we're going to delete one and this levels so this is the appearance of your screen or the 56 00:13:08,509 --> 00:13:21,710 the screen of your smartphone to this app. But now we need to do a program 57 00:13:21,710 --> 00:13:29,509 and to do the program we go to blocks. So here in blocks the first thing that you 58 00:13:29,509 --> 00:13:44,129 usually do in the program is create a variable. So we set 1 which is the number 1. 59 00:13:44,129 --> 00:14:45,840 So, first you need to create the variables and initiate them to a value, which is very 60 00:14:45,840 --> 00:14:53,320 easy, but we need to do this blocks. 61 00:14:53,320 --> 00:15:25,809 firstly we are going to initiate variables initiate global initiate we 62 00:15:25,809 --> 00:15:41,070 are going to initiate to four variables this is one two three and four well this 63 00:15:41,070 --> 00:16:06,279 is number one this is number two this is addiction and multiplication so we are 64 00:16:06,279 --> 00:16:28,370 going to initiate them to all what multiplication is better than all one 65 00:16:28,370 --> 00:16:40,980 and then when the button click so we're going to the button when the button 66 00:16:40,980 --> 00:17:14,339 click and set number one and set number two text box to text this was one this was two 67 00:17:14,339 --> 00:18:23,380 So, now, set and set addiction and multiplication. Addiction to the word. Addiction is the sum of global number 1 and global number 2. 68 00:18:23,380 --> 00:19:01,559 And multiplication is global number 1, global number 2. 69 00:19:01,559 --> 00:19:56,519 So finally we have the textbox 3, so test, and textbox 4, 2, addiction, and multiplication. 70 00:19:56,519 --> 00:20:02,079 So now your application is finished. 71 00:20:02,079 --> 00:20:09,519 The next step is to implement in what? 72 00:20:09,519 --> 00:20:17,680 You can implement in your mobile phone or better, my advice is that you test it using 73 00:20:17,680 --> 00:20:26,119 emulator, but that is what we are going to explain in the next video. 74 00:20:26,119 --> 00:20:38,079 For today you have finished, just only add that you also can upload, for example, some 75 00:20:38,079 --> 00:20:57,279 music you want here as mp3 format or you can also add it if you want a picture in a gpa format 76 00:20:57,279 --> 00:21:07,180 And that is all for today, I hope you will enjoy this video and I see you next time.
