WEBVTT 00:01.020 --> 00:01.560 Okay. 00:02.040 --> 00:05.730 Let's talk about a build process now. 00:05.880 --> 00:12.660 Well, this process is kind of complicated outside of the scope of this tutorial because this might 00:12.660 --> 00:14.250 be a tutorial itself. 00:14.250 --> 00:20.480 So there's a lot of different things that you need to do to prepare your application for a production. 00:20.490 --> 00:24.420 So what we need to do is we need to start with two things. 00:24.420 --> 00:30.780 Basically, if you would like to publish your application on Google platform, which is Android platform, 00:30.780 --> 00:33.660 you will need to have a Google developer account. 00:34.020 --> 00:40.350 So you can go to Developer.android.com and then you will sign in with your Google account. 00:40.350 --> 00:50.220 And then you need to create a developer account and that costs you $25 or your currency in your country 00:50.220 --> 00:53.910 or equivalent of that money in your country. 00:53.910 --> 01:00.510 So basically, once you will have the Google developer account, that's an account for lifetime. 01:00.510 --> 01:02.670 So you pay $25 and that's it. 01:02.700 --> 01:08.550 Once you will have that, you will be able to access Google Play and then you can create application 01:08.550 --> 01:12.060 and you can upload your APK apk file there. 01:12.390 --> 01:14.700 So that's been said. 01:14.730 --> 01:20.220 You will need to have a Google developer account to publish your app on Google Market. 01:20.520 --> 01:27.300 Another thing is what you will need to have is you will need to have developer account for Apple and 01:27.300 --> 01:30.960 this is much more expensive and much more complicated to do. 01:30.960 --> 01:34.260 So basically well, creating an account is not that complicated. 01:34.260 --> 01:42.570 You create an account, then you pay for it and you pay $100 or whatever the amount is in your country. 01:42.600 --> 01:45.330 You're paying $100 for a year. 01:45.330 --> 01:46.500 Yes, for a year. 01:46.500 --> 01:54.660 So every single year you need to pay $100 it to maintain or euro or whatever the currency. 01:54.660 --> 01:58.080 You have to maintain your developer account. 01:58.080 --> 02:04.570 If you don't pay it, then you lose access to your applications and you won't be able to to have them 02:04.570 --> 02:05.500 on the market. 02:05.500 --> 02:07.150 So that's really unfair. 02:07.150 --> 02:10.060 I don't think it's a fair price for developers. 02:10.060 --> 02:14.500 They just want to have extra profit on it and that's it. 02:14.500 --> 02:19.510 So I strongly disagree with their politics, but nothing we can do about it. 02:19.540 --> 02:25.120 If you would like to publish applications on Apple Market on the App Store, then you need to go for 02:25.120 --> 02:25.450 it. 02:25.450 --> 02:30.010 So once you will have that, the process is kind of complicated. 02:30.010 --> 02:33.670 You need to have sign certificates and and so on. 02:33.670 --> 02:41.830 So that's and that is the reason why I don't want to go through all of that on this tutorial, but this 02:41.830 --> 02:43.600 will be the way to do so. 02:43.600 --> 02:49.600 Basically, if you would like to know more, what is the full process of building your application? 02:49.600 --> 02:58.180 You can go to Docs export IO and then you can pick the latest version and insight manage workflow. 02:58.180 --> 03:01.330 If you scroll down, you will see distribution. 03:01.330 --> 03:04.480 Your app and you will have building standalone application. 03:04.480 --> 03:10.120 So basically you have overview and then app signing, deploy to app stores and so on and so on. 03:10.120 --> 03:18.010 So that's a very useful article if you would like to publish, your application will go here first and 03:18.190 --> 03:19.540 read articles. 03:19.540 --> 03:27.280 So what I can show you instead, I'm not going to build a full application, but what I want to show 03:27.280 --> 03:28.480 you is an example. 03:28.510 --> 03:30.250 How would you do that? 03:30.250 --> 03:34.210 So normally what we have here is we have an expo. 03:34.480 --> 03:41.290 So Expo comes with some kind of built in functionality and one of the functionality is to build the 03:41.290 --> 03:42.550 app for us. 03:42.580 --> 03:50.890 Otherwise if we will use React Native Init command, we will need to handle that on ourselves. 03:50.890 --> 03:56.320 So that's a good thing that we use Expo because Expo can do it for us. 03:56.320 --> 03:58.420 So how how Expo will do it? 03:58.420 --> 04:07.030 Basically we use command Expo build and then let's say Android, we can do Android or iOS. 04:07.030 --> 04:11.410 And as I said, we are not going to be able to do iOS on, not on Mac. 04:11.410 --> 04:14.320 So I will do Expo Build Android. 04:18.470 --> 04:20.180 An expo might. 04:20.360 --> 04:22.820 Expo might actually ask you for. 04:23.120 --> 04:24.050 For an account. 04:24.050 --> 04:28.820 So right here in the terminal, it will ask you Do you have an account with Expo? 04:29.390 --> 04:30.530 You can create one. 04:30.530 --> 04:34.550 So providing just the email address, username password. 04:34.550 --> 04:37.670 You can do everything here and it will be done already. 04:37.670 --> 04:38.120 You've done it. 04:38.120 --> 04:39.380 So it's not asking me. 04:39.380 --> 04:41.230 But be prepared for that. 04:41.240 --> 04:44.210 It's free, so you don't need to worry about that. 04:44.210 --> 04:46.070 So now we have an error. 04:46.070 --> 04:52.310 So what is happening here is basically I don't have any information about the build so far. 04:52.310 --> 05:01.130 So what I need to do is I will go to the App.json here and if you scroll down here, you have iOS and 05:01.130 --> 05:03.680 then some settings for iOS. 05:03.680 --> 05:15.800 What I need to do is I will need to create a settings for Android and then I need to put a package. 05:17.690 --> 05:21.200 And then name of the package package needs to be unique. 05:21.200 --> 05:28.760 So that means on the apple on the market, they cannot be two applications with the same package name. 05:28.760 --> 05:35.030 So usually what you will do if you know, own a domain, you will do something like something like a 05:35.030 --> 05:36.080 reverse domain. 05:36.080 --> 05:41.660 So my domain is I own a website, which is true. 05:41.660 --> 05:43.240 Sign that. 05:43.650 --> 05:45.170 That's my website. 05:45.170 --> 05:49.910 So my reverse domain will be I true sign. 05:50.870 --> 05:57.290 And then I can also provide the name of the application, let's say movies like that. 05:57.290 --> 05:59.390 So that will be my package. 05:59.390 --> 06:05.690 And that package will be unique because no one else have that domain. 06:05.690 --> 06:11.690 So this is my domain and no one ever use it before and can't use it because I'm paying for it. 06:11.690 --> 06:16.400 And then name of the applications you can have under your domain multiple application. 06:16.400 --> 06:23.850 So that's the android and you can do the same package for iOS, but we are not going to build iOS here, 06:23.850 --> 06:28.440 so I will just save it and then I will repeat the expo build Android. 06:39.380 --> 06:43.610 And it's trying and it's building an application for me. 06:49.940 --> 06:56.360 And I have to say also for Android, what you will need to do is you will need to sign your application 06:56.360 --> 06:57.360 with a key. 06:57.380 --> 06:59.290 So you will need to prepare that. 06:59.300 --> 07:04.520 Otherwise this expo will produce an APK file that you can actually download. 07:04.520 --> 07:11.060 You can give it to someone, and from that file you can install your application on your phone, but 07:11.270 --> 07:13.400 you will be asked untrusted source. 07:13.400 --> 07:21.440 So basically you click it and then Android will ask you Do you want to install application from an untrusted 07:21.440 --> 07:22.070 source? 07:22.100 --> 07:24.950 Or you need to go to the settings and enable that. 07:24.950 --> 07:31.310 So basically to have a production ready application, you will need to also sign it. 07:31.310 --> 07:39.800 So what is happening here is Expo is building application for me and we can have a handy URL here that 07:39.800 --> 07:41.660 I will copy and I will go to. 07:44.360 --> 07:46.370 To the website and I will paste it here. 07:46.370 --> 07:54.320 So what is happening here is basically that my account that I have on Expo and whatever you click build, 07:54.320 --> 08:00.620 you will need to assign with your expo account and then you can have some logs here. 08:00.620 --> 08:07.880 So basically the application is, is being built now. 08:07.880 --> 08:11.030 So whatever we will it, it will do it. 08:11.030 --> 08:12.830 We can see some logs there. 08:12.830 --> 08:20.780 Once it will be done, then you can download the the file and the APK file will be ready for you. 08:20.900 --> 08:28.040 As I said, it's not going to be optimized, it's not going to be production ready because the Google 08:28.160 --> 08:34.280 platform won't accept the APK file that hasn't been signed with our key. 08:34.280 --> 08:36.650 So we'll need to do that as well. 08:37.160 --> 08:44.430 But as I said, if you would like to have that process and finish that, that will be the best place 08:44.430 --> 08:45.990 to do an expo. 08:45.990 --> 08:50.700 It is great to help you building that for you. 08:50.700 --> 08:54.120 Otherwise you'll need to handle a lot of things by yourself. 08:54.120 --> 08:58.110 So I would go definitely for Expo because it's much more simpler.
