- With Angular (2+), you can already build highly reactive and engaging web apps. Wouldn’t it be amazing to use that same tech stack and knowledge to build real native mobile apps for iOS and Android? NativeScript enables you to do exactly that! You build a normal Angular app and manage your entire app logic via Angular + TypeScript.
To start building your first React Native Android app, you must:
![Free Free](/uploads/1/3/3/9/133901322/711659860.png)
- Connect to your repository service account (GitHub, Bitbucket, VSTS, Azure DevOps).
- Select a repository and a branch where your app lives.
- Choose the project's
package.json
that you want to build. - Set up your first build.
Note
For the app to run on a real device, the build must be code signed with a valid certificate.
1. Linking your repository
If you haven't previously connected to your repository service account, you must do this first. Once your account is connected, select the repository where your React Native project is located. You must have admin and pull permissions to setup a build for a repository.
2. Selecting a branch
After selecting a repository, select the branch you want to build. Avg free 2016 antivirus download. By default, App Center lists all active branches.
3. Setting up your first build
Before your first build, you must configure the React Native project.
3.1. Project
Select your project’s
package.json
. App Center will automatically extract information from its associated build.gradle file, including dependencies, build tools version, build types, and product flavors.Note
For best performance, the analysis is currently limited to four directory levels including the root of your repository.
3.2. Build variant
The available build variants will populate from the Build Types and Product Flavors specified in the project's build.gradle file. Select which build variant should be built.
Note
App Center Build supports finding build variants as the combination of a Build Type (debug, release or custom defined) and one optional Product Flavor. Detecting combinations of multiple product flavors are not supported at this time.
3.3. Node.js version
Select the Node.js version to use for the buildRead more about how to select Node.js version
3.4. Build triggers
By default, a new build is triggered every time a developer pushes to a configured branch. This is referred to as 'Continuous Integration'. If you prefer to trigger a new build manually, you can change this setting in the configuration pane.
3.5. Build Android App Bundle (.aab)
The Android App Bundle is a distribution format which can be uploaded to the Play Store and is used to generate optimized APKs for specific devices. You can find out more about the Android App Bundle in the official Android documentation which also helps you understand whether you want to build a bundle in addition to your regular
.apk.
Toggle on the option for Android App Bundle to produce an
.aab
in addition to the .apk
. If the build.gradle
file contains the android.bundle
block, this option will automatically be toggled on.3.6. Increment version number
When enabled, the version code in the AndroidManifest.xml of your app automatically increments for each build. The change happens during the actual build and won't be committed to your repository.
3.7. Launch your successful build on a real device
Use the newly produced APK file to test if your app starts on a real device. This will add approximately 10 more minutes to the total build time. Read more about how to configure launch tests.
3.8. Code signing
A successful build will produce an
.apk
file and an additional .aab
file if enabled. To release the build to the Play Store, it must be signed with a valid certificate stored in a keystore. To sign the builds produced from a branch, enable code signing in the configuration pane, upload your keystore to your repository, and provide the relevant values in the configuration pane. You can read more about Android code signing App Center's Android code signing documentation. The .aab
will be signed using the same credentials as the .apk
.3.9. Distribute the build
You can configure each successful build from a branch to be distributed to a previously created distribution group or a store destination. You can add a new distribution group or configure a store connection from within the Distribute service. There is always a default distribution group called 'Collaborators' that includes all the users who have access to the app.
Note
If distributing to the Google Play Store, an Android App Bundle (
.aab
) is preferred and will be distributed if enabled. For App Center distribution groups and Intune store destinations, a regular .apk
will be used even if an .aab
is also generated.4. Build results
After a build triggers, the build will be in one of the following states:
- queued - the build is in a queue waiting for resources to be freed up
- building - the build is running and performing the predefined tasks
- succeeded - the build is completed and it has succeeded
- failed - the build has completed but it has failed; you can troubleshoot what went wrong by downloading and inspecting the build log
- canceled - the build has been canceled by a user action or it has timed out
4.1. Build logs
For a completed build (succeeded or failed), download the logs to understand more about how the build went. App Center provides an archive with the following files:
https://icmieo.weebly.com/download-latest-version-of-opera-mini-browser-for-android.html. The build step specific logs (located in the
build/
directory of the archive) are helpful for troubleshooting and understanding in what step and why the build failed.4.2. The app (.apk)
The
.apk
file is an Android application packaged file which stores the Android app. If the build has been correctly signed, the app can be installed on a real device and deployed to the Play Store. If the build has not been signed, the app can run on an emulator or be used for other purposes.5. Supported versions and requirements
The minimum version supported to build Android apps is 4.0.3 (API level 15). Android apps can have a lower minimum API level required to run, but have to target at least API level 15.
6. Build tips
6.1. Yarn
The Yarn package manager is a faster, more deterministic replacement for
npm
. If a yarn.lock
file is present in your repository next to package.json
, then App Center will use Yarn, doing yarn install
at the start of the build. Otherwise, it will do npm install
.6.2. Custom build scripts
In addition to App Center's custom build scripts you might want to use npm-scripts for example when your React Native app uses TypeScript and you have to run the
tsc
compiler at build start. Add a postinstall
script in the package.json
like this:Postinstall scripts run right after all the
package.json
packages are installed, so you use those packages in your script.6.3. Building multiple APKs
For React Native on Android, universal APK generation is disabled by default. If your app configuration is set up to build multiple APKs, e.g. different ones per CPU architecture or screen configuration, you need to make sure a universal APK is built as well. App Center's build system works with one main APK file and will ignore all APKs specific to a certain CPU/ABI or screen density.
To learn more about APK splits and how to build a universal APK, please read the corresponding Android developer guide. Consequently, make sure that
universalApk
is set to true
for your React Native build configuration.![Native Native](/uploads/1/3/3/9/133901322/306254103.png)
Apple’s App Store is the holy grail for mobile developers. With React Native you can develop native apps for Android and iOS using a single code-base but getting things ready for publishing can be tricky, especially if you are starting with an originally Android-only application.
Here you’ll be starting with the code from a previous monster Okta blog post designing and publishing a calculator-like app on the Android Play store, which includes authentication via Okta.
For this post, you’ll first get the Android app to work well on iOS, as well as adding a splash screen and app icon. Then you’ll go through the signing process and publishing onto the App Store.
Start by cloning the repo and installing all the required libraries.
From here you should be able to say
react-native run-android
to deploy to an emulator or attached Android phone. Everything should work fine.Configure Authentication for Your React Native iOS App
Right now when you click Login you will be taken to an Okta login page. This is connected to an Okta account I used for development. You need to create your own account and configure this app to use it.
First, sign up for a free Okta developer account, or log in if you already have one. Then navigate to Applications > Add Application. Select Native and click Next. Choose a name and click Done. Note your Login redirect URI and the Client ID since you have to add them to your app.
Now in your
App.js
find where the config variable is defined (near the top) and change the pertinent values to that of your Okta app:Running Your React Native App on iOS Simulator
Start by running
react-native run-ios
from a Mac computer. An iOS simulator should appear and in the console, your project will compile.NOTE: If you get an error
Print: Entry, ':CFBundleIdentifier', Does Not Exist
there are severalissues on Github tracking this with various suggestions on fixing it. The simplest might just to open up ios/prime_components.xcodeproj
in Xcode and build the project from there.You should see an error
'AppAuth/AppAuth.h' file not found
. You need to link the AppAuth library to iOS. The easiest is with Cocoapods. Put the following into ios/Podfile
:After having installed Cocoapods change into
ios/
and run pod install
. This will take a while. Now close Xcode and open ios/prime_components.xcworkspace
(note: the workspace, not the project!) in Xcode. The pods should appear as a separate project. Select a device and the project should build and run just fine (just click the play button). You may have to change the bundle identifier if the one used in this tutorial is already taken.At this point, the factorization should work but if you click Login it will crash because your AppDelegate class needs to conform to
RNAppAuthAuthorizationFlowManager
. Open AppDelegate.h
and change it to the following:Now the login button should take you through the authorization process.
Adjust Styling in Your React Native iOS App
When I ran the app, the font was a bit large and the banner looked like it was showing the background behind the app. To fix these:
- In
components/Button.js
change the font size to 25 - In
components/Header.js
change the font size to 65 - In
components/Input.js
change the flex to 1.5 and the font size to 60
The transparency issue in the header is from the iOS status bar showing. To hide this import
StatusBar
from react-native
in App.js
and add <StatusBar hidden />
at the top of the container:The app should look correct now.
Set the Icon and Display Name and Run on a Device
As in the previous post, you can use an app like Iconic to create an icon (though that one is for Android). Once you have an icon you can use an online service like MacAppIcon to get all the sizes you need. Then in Xcode open the
prime_components
project and click on Images.xcassets
. You will see all the icons you need to fill it - simply drag them the correct sizes from Finder.You will also want to change the display name of your project to fix the app name on your device. This is in the Identity section of the project settings.
Make sure you have set up the signing team and also that the Build Active Architectures Only is set to Yes for both debug and release, for both projects - This can fix a lot of integration problems with the AppAuth library.
Android 4.4 kitkat rom for galaxy y download. Once done, you should be able to deploy to a device and see a proper icon and name for your app.
Create a Splash Screen for Your React Native iOS App
iOS apps have splash screens while they load. React Native creates a basic
LaunchScreen.dib
image which is just a white screen with the app’s name.The easiest way to change this is by using the React Native Toolbox.
- Create a square image of at least 2208x2208 pixels
- Make sure to have plenty of margin around your symbol
For example:
A good image manipulation program to use is GIMP.
Next, install the toolbox as well as ImageMagick:
Now place your image inside of your project, close the workspace inside of XCode and run the following command:
Make sure to specify the correct project name! (In this case it is prime_components and not
prime-components
). The images should be generated and your project updated. Uninstall your app from the simulator/device and re-deploy from Xcode and you should see the new splash when loading the app.Submit Your React Native App to the iOS Store
What follows are instructions on submitting your app to the App Store but since the Prime Components app already exists this is for those who have another app they’d like to submit. In that case, follow the instructions from the previous blog post (linked above) on how to design and build your own app before continuing here.
Review Guidelines
Before you begin it’s worth reading through Apple’s App Store Review Guidelines. In plain English, it explains what you need to make sure your app is ready (and why the app might be rejected during review). Things like safety and performance are covered, as well as business practices like advertising. A lot of it is very sensible.
App Store Connect
To get started login to App Store Connect and accept the terms and conditions. Then click on the My Apps icon.
Click on the plus sign and select New App. Fill in the required values. Here the Bundle ID is the bundle identifier you set in your project settings. It’s important this is a unique value - good practice is to start with a website you own like com.myblog.my_app. You can’t change this once you’ve submitted a build.
Once everything is filled in you will get to the app management page with three tabs for the App Store section: App Information, Pricing and Availability, and the iOS submission page.
Fill out everything as best you can. Any missing information will come out when you try to submit your app for review. Set the pricing to free, and the availability to all territories. Select two categories for your app in App Information. This is for people who are browsing for new apps.
Because you are not charging for your app and there is no advertising a lot of this process will go smoothly.
Build an Archive
iOS apps are distributed with archives. To build the archive, make sure the RnAppAuth is added to the target dependencies in the Build Phases of the
prime_components
project. Then go to Product and select Archive. This will rebuild and archive everything into one file.Once done, the Organizer window should pop-up (which you can find in the Window menu):
From here you can validate your app. Click on Distribute to upload it to App Store Connect. Once that is done you should see the build in the submission page.
Screenshots
You need to add a few screenshots for your app. To do this simply go to the simulator menu - there is a screenshot option there. You might like to use a service like MockUPhone to give your screenshots a phone border.
Then you need to resize them in an app like Gimp. Your screenshots need to be the right size.
Once you’re finished, under the Prepare for Submission page select iPhone 5.5” Display (this is the only one you need to fill out), upload the screenshots you have.
Privacy Policy
Since October 2018 all apps in the App Store need a privacy policy, specified as a URL. Basically, you need to explain what data you collect and what you do with it. In this case, no data collected at all but you need to specify that and host a write-up for it on a website. There are several examples of what a privacy policy in this situation might look like such as this one.
Submission
Once all looks ready, click on the Submit for Review button in the preparation page. Here you will be asked to give your app a rating (you’ll be asked several questions about the app’s content). Make sure you’ve filled out the information of where reviewers will be able to contact you.
Once through, you should hear back within two days.
