How To Run Native Apps Mac
It's always a good idea to test your app on an actual device before releasing it to your users. This document will guide you through the necessary steps to run your React Native app on a device and to get it ready for production.
How to Install React Native on MAC step by step. React Native has fast become one of the hottest frameworks for building cross platform mobile apps. Based on JavaScript and Facebook’s React Library it focuses on performance and tight integration with the native platforms supports. With Facebook invested in the framework and React’s learn once, write anywhere philosophy, React has a bright. You can’t natively run iPad apps on a Mac computer without using an emulator, though that will change with a new generation of Macs, set to come out by the end of 2020. It may be too much to argue, as Gruber does, that 'The whole point of the Mac is to be a great platform for native Mac apps,' given that the Mac is exceptional as a platform for non-native Mac. If you used Expo CLI or Create React Native App to set up your project, you can preview your app on a device by scanning the QR code with the Expo app—but in order to build and run your app on a device, you will need to eject and install the native code dependencies from the environment setup guide.

1. Enable Debugging over USB#
Most Android devices can only install and run apps downloaded from Google Play, by default. Hot to kill apps running on a mac. You will need to enable USB Debugging on your device in order to install your app during development.
To enable USB debugging on your device, you will first need to enable the 'Developer options' menu by going to Settings → About phone → Software information and then tapping the Build number row at the bottom seven times. You can then go back to Settings → Developer options to enable 'USB debugging'.
2. Plug in your device via USB#
Let's now set up an Android device to run our React Native projects. Go ahead and plug in your device via USB to your development machine.
Next, check the manufacturer code by using lsusb (on mac, you must first install lsusb). lsusb should output something like this:
These lines represent the USB devices currently connected to your machine.
You want the line that represents your phone. If you're in doubt, try unplugging your phone and running the command again:
You'll see that after removing the phone, the line which has the phone model ('Motorola PCS' in this case) disappeared from the list. This is the line that we care about.
Bus 001 Device 003: ID 22b8:2e76 Motorola PCS
From the above line, you want to grab the first four digits from the device ID:
22b8:2e76
In this case, it's 22b8. That's the identifier for Motorola.
You'll need to input this into your udev rules in order to get up and running:
Make sure that you replace 22b8 with the identifier you get in the above command.
Now check that your device is properly connecting to ADB, the Android Debug Bridge, by running adb devices.
Seeing device in the right column means the device is connected. You must have only one device connected at a time.
3. Run your app#
Type the following in your command prompt to install and launch your app on the device:
If you get a 'bridge configuration isn't available' error, see Using adb reverse.
Hint: You can also use the React Native CLI to generate and run a Release build (e.g. npx react-native run-android --variant=release).
Connecting to the development server
You can also iterate quickly on a device by connecting to the development server running on your development machine. /delete-app-off-of-mac.html. There are several ways of accomplishing this, depending on whether you have access to a USB cable or a Wi-Fi network.
Method 1: Using adb reverse (recommended)#
You can use this method if your device is running Android 5.0 (Lollipop) or newer, it has USB debugging enabled, and it is connected via USB to your development machine.
Run the following in a command prompt:
To find the device name, run the following adb command:
You can now enable Live reloading from the Developer menu. Your app will reload whenever your JavaScript code has changed.
Method 2: Connect via Wi-Fi#
You can also connect to the development server over Wi-Fi. You'll first need to install the app on your device using a USB cable, but once that has been done you can debug wirelessly by following these instructions. You'll need your development machine's current IP address before proceeding.
Open a terminal and type /sbin/ifconfig to find your machine's IP address.
- Make sure your laptop and your phone are on the same Wi-Fi network.
- Open your React Native app on your device.
- You'll see a red screen with an error. This is OK. The following steps will fix that.
- Open the in-app Developer menu.
- Go to Dev Settings → Debug server host & port for device.
- Type in your machine's IP address and the port of the local dev server (e.g. 10.0.1.1:8081).
- Go back to the Developer menu and select Reload JS.
