For the most part, this approach works perfectly, specially if you’re part of small team and lack the resources to develop full native code for both Apple and Android devices, but you need to be aware of its pros and cons, as in any other decision you have to make. Fortunately, Airbnb published a very nice article covering this subject, so make sure you read it.

Well, this article will show how to get your app up and running on simulators for both iOS and Android devices, as well as how to set up your project.
Installing Xcode
To use iOS simulators, you’ll need a Mac. You may be able to run your app using services like Appetize (which I haven’t tested), but given that my main development environment is macOS, this is what I’ll focus on this article.
Many web developers out there are used to installing only the command-line tools, without the Xcode IDE, so they can build extensions or even use homebrew. To use iOS simulators, you’ll need the full thing, so go to the App Store and install Xcode.
This may take a while. When is done, open Xcode and install the extra components.
Now, you can install the iOS simulators. Go to “Preferences > Components” and download as many simulators as you want. I usually install only the latest version, but that’s on you and how far back you want to support.
As far as Xcode goes, you’re done! Now, let’s set up the Android emulator.
Installing Android Studio
Android’s ecosystem is different than Apple’s. First, you can install several third party emulators, some free, some paid. If you don’t want to choose, just use Android Studio, the official IDE.
After downloading Android Studio, move the app to your
/Applications
folder.Now, open the app and follow the instructions. If you don’t have an Android SDK available, you’ll see a screen like the following:
Just click on “Next” when Android Studio will install it for you.
When is done, you be presented with a welcome screen.
Go to “Configure > SDK Manager”, then head to “SDK Tools”. Click on the checkbox to install the Build Tools, which will be used by React Native command-line tools. Click in “Apply” to install it.
Now, notice the Android SDK Location available on the image above. You’ll need this value to define an environment variable on the terminal. This is where things get tricky because you may have configured your terminal different than mine, but in general lines, you’ll have to do one of the following:
- If you use bash, add the following lines to
~/.bashrc
. - If you use zsh, add the following lines to
~/.zshrc
.
Restart your terminal to reload your configuration. You can check your configurations like the following:
If you see anything too far from the above output, make sure you added the
export
lines to the correct files and restarted your terminal.Finally, you can create a virtual device. Back to the welcome screen, go to “Configure > AVD Manager”.
Click on “Create Virtual Device” and select a device definition. In this example I’m selecting Pixel 3.
When you’re done, click on “Next”. Now you have to choose which Android version you’re going to use. You can go with the latest stable version available, which right now is Android Pie. Make sure you click the “Download” link.
After downloading the system image, click on “Next” once more. You’ll be presented with the device profile you’re creating. Just click “Finish”.
Now you’re back to the list of virtual devices available on your computer and you can always create more.
To start the emulator, click the play button available under the “Actions” column. Always remember to start the emulator by clicking the play button; otherwise, you’ll see a message like
No connected devices!
when trying to run React Native on the Android emulator.You can also start the emulator from the command-line. All you have to do is using the
emulator
Remove duplicates in photos app mac. command.Congrats! You’re done with configuring emulators. Now, let’s spin up a sample app and run it on both simulators.
Configuring React Native
The official documentation recommends installing react-native-cli globally, but I avoid installing global packages. We’re going to use
npx
to generate the app skeleton.Go to the projects directory with
cd sample
and run react-native run-ios
. This will compile the app, install it on the emulator and run a separate tab with Metro, the JavaScript bundler for React Native developed by Facebook.This is the tab you should keep an eye on because any errors while running your app will be outputted to it. After everything is up and running, you’ll be able to see the sample app running on the iOS simulator.
Great! What about Android simulator? Make sure you have the virtual device running (remember, from the Android Studio’s welcome screen, choose “Configure > AVD Manager”, then press the play button). You can check for running devices by executing
adb devices
.Now, you can run
react-native run-android
. This will also compile a bunch of stuff and initialize the emulator.You’ll be able to see the app running on the Android simulator if everything went smoothly.
Running physical devices
At some point you’re better off testing your apps on physical devices. This can help you fix bad user experience that wouldn’t bother on simulators.
Running the app on your iPhone
To run your app on the iPhone, open
ios/sample.xcodeproj
on Xcode. You can use open ios/sample.xcodeproj
to open this file from your terminal.First, you have to select a developer profile. Click on the project name and go to the target you’re building (in this case,
sample
). Change the bundle identifier to your own domain, otherwise you won’t be able to build the project. Then click “Add Account”, enter your Apple ID and password, and select your name under the dropdown. You may also have to select your developer account for the sampleTests
target.Connect your iPhone to the computer and click the simulator selector.
Install Create React App Windows
Your device will be available on the top of the list.
Finally, click the “Build and Run” button, or press cmd-R. This will install and open the app on your iPhone.
Running the app on your Android
I didn’t have an Android device, but decided to buy one to test the app on the real thing. After some research, I decided to buy a Xiaomi Mi A2 which costed me around $170 on Amazon. It’s a very nice device, even for daily usage. The good thing about it is that it comes with stock Android, and not the shitty modified version that some companies ship (looking at you, Samsung).
First, make sure Developer Options is enabled. Here, things can get tricky. Different devices can be activated differently. In my case, I had to go to “Settings > About phone” and tap the Build number 7 times in order to activate the developer mode. Then go to “Settings > System > Advanced > Developer Options” and activate “USB Debugging”.
To verify that your device is ready, run
adb devices
on your terminal.Now, run
react-native run-android
. This command will install and open the app on your Android device.Using TypeScript
This step is optional, but if you’re planning to release your app as an open-source project you may consider using TypeScript, the typed language that compiles down to JavaScript, created by Microsoft.
For new projects, all you have to do is running the generator with
--template typescript
.For existing projects, you’ll need to manually configure everything that the TypeScript template provides. I won’t cover this migration process here, so make sure you read the article published on the official blog.
Wrapping up
Despite all the efforts on developing the ecosystem, React Native is still immature and you’ll find that developing apps can be challenging. But even with all these difficulties, I consider React Native the best solution for small companies/teams that need to develop native apps.
Before deep diving into React Native, ask yourself if a PWA is a viable solution. Unfortunaly, PWA comes with its own challenges, like a different mindset for installing apps and inconsistencies between Android and iOS, as well as several device limitations, but it may be a good first step towards mobiles apps when responsive web is not enough, but React Native is too much.
How To Install Create React App On Mac Computer
Contents
To run and test your React Native application on the android device you need to set up the Android Environment. Setting up your development environment can be somewhat tedious if you’re new to Android development. If you’re already familiar with Android development, there are a few things you may need to configure. In either case, please make sure to carefully follow the next few steps. Here are 3 Steps to Setting up Android Development Environment & Android Studio. If you want to install the same on Mac OS then you can visit Setting up Android Development Environment & Android Studio in Mac OS.
1. Install Android Studio
Download and install Android Studio. Choose a “Custom” setup when prompted to select an installation type. Make sure the boxes next to all of the following are checked:

- Android SDK Platform
- Performance (Intel ® HAXM)
- Android Virtual Device
Then, click “Next” to install all of these components.
Once setup has finalized and you’re presented with the Welcome screen, proceed to the next step.
2. Install the Android SDK
Android Studio installs the latest Android SDK by default. Building a React Native app with native code, however, requires the
Android 9 (Pie)
SDK in particular. Additional Android SDKs can be installed through the SDK Manager in Android Studio.The SDK Manager can be accessed from the “Welcome to Android Studio” screen. Click on “Configure”, then select “SDK Manager”.
The SDK Manager can also be found within the Android Studio “Preferences” dialog, under Appearance & Behavior → System Settings → Android SDK.
Select the “SDK Platforms” tab from within the SDK Manager, then check the box next to “Show Package Details” in the bottom right corner. Look for and expand the
Android 9 (Pie)
entry, then make sure the following items are all checked:- Android SDK Platform 28
- Intel x86 Atom_64 System Image or Google APIs Intel x86 Atom System Image
Next, select the “SDK Tools” tab and check the box next to “Show Package Details” here as well. Look for and expand the “Android SDK Build-Tools” entry, then make sure that
28.0.3
is selected.Finally, click “Apply” to download and install the Android SDK and related build tools.
3. Configure the ANDROID_HOME environment variable
The React Native tools require some environment variables to be set up in order to build apps with native code.
3.1. For Windows User
Open the System pane under System and Security in the Windows Control Panel, then click on Change settings. Open the Advanced tab and click on Environment Variables. Click on New to create a new
ANDROID_HOME
user variable that points to the path to your Android SDK:The SDK is installed, by default, at the following location:
How To Install Create React App On Mac Os
You can find the actual location of the SDK in the Android Studio “Preferences” dialog, under Appearance & Behavior → System Settings → Android SDK. Open a new Command Prompt window to ensure the new environment variable is loaded before proceeding to the next step.
Add platform-tools to Path
Open the System pane under System and Security in the Windows Control Panel, then click on Change settings…. Open the Advanced tab and click on Environment Variables…. Select the Path variable, then click Edit. Click New and add the path to platform-tools to the list.
The default location for this folder is:
3.2. For Linux Users
Assuming you have the SDK extracted at
~/Android/Sdk
Add the following lines to your
$HOME/.bash_profile
(If you unable to find then try for $HOME/.bashrc
) config file:To test if you have set it up correctly run the below commands on a terminal window https://everclean605.weebly.com/blog/mac-folder-encryption-app.
- Run//will print the path to your SDK /home/Android/Sdk
- Run//will print /home/<user>/Android/Sdk/tools/android
- Run//If it opens up Android SDK Manager, you are good to go.
Create React App Globally Install
This is how you can install the Android Studio and can set up the Android Development Environment. Next, You will need an Android device to run your React Native Android app. This can be either a physical Android device or more commonly, you can use an Android Virtual Device which allows you to emulate an Android device on your computer. To create an Android Virtual Device you can follow how to create an Android Virtual Device and different ways to launch the Emulator.
