After that, we’ll look at how to run an example React Native app on the emulator and on a physical Android device. However, running React Native apps on Android requires some initial setup.In this post, we’ll walk through all the initial setup required to set a suitable development environment. The process can be as simple as connecting your Android device to the computer you use for development and running a command. For example, you can set up an emulator based on a device like the Google Pixel and use your preferred version of the Android operating system.If you own a physical Android device and prefer to test your app on it, React Native has got you covered there too.The first time you run Android Studio, it’ll prompt you to install additional files. After that, launch the executable and follow the prompts to complete the installation process.Once you’re done with the installation process, go ahead and start Android Studio.

MacOS SetupFollow these steps to set up environment variables on your macOS computer.Run either sudo nano ~/.bash_profile (for bash) or sudo nano ~/.zshenv (for zsh) to edit your shell configuration file. This step will allow React Native to interact with the Android SDK via the command line. If you already have a project setup, you can skip the section. Open the control panel (in category view), then navigate to Systems and Security → Systems.In the next section, we’ll be creating a new React Native project, which we’ll use to test our setup so far.
