Assuming that you have

React Native

installed, you can run the following command in your terminal to run your React Native app on an

Android

device or simulator:

react-native run-android

If you’re running your app on a physical device, you may need to enable Developer options and USB debugging first.

If you’re using a simulator, you can use the React Native CLI to launch the simulator of your choice. For example, to launch the iOS Simulator, run the following command:

react-native run-ios

The React Native CLI will also build your app before running it. If you want to launch your app without building it first, you can use the –no-build option.

Once your app is running, you can use the React Native Debugger to view the state of your app and inspect the props and state of your React components.

2. Plug in your device via USB​

Let’s now configure an Android device to run our React Native projects. Connect your device via USB to your development machine now.

Next, check the manufacturer code by using lsusb (on mac, you must first install lsusb). lsusb should output something like this:

$ lsusbBus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching HubBus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hubBus 001 Device 003: ID 22b8:2e76 Motorola PCSBus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching HubBus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hubBus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hubBus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

You want the line that represents your phone. If you’re in doubt, try unplugging your phone and running the command again:

$ lsusbBus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching HubBus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hubBus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching HubBus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hubBus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hubBus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

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

You need to copy the device ID’s first four digits from the line above.

22b8:2e76

In this case, it’s 22b8. That’s theidentifier for Motorola.

You’ll need to input this into your udev rules in order to get up and running:

echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", MODE="0666", GROUP="plugdev"' | sudo tee /etc/udev/rules.d/51-android-usb.rules

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.

$ adb devicesList of devices attachedemulator-5554 offline   # Google emulator14ed2fcc device         # Physical device

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:

$ npx react-native run-android

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. 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)​

If your device runs Android 5, you can employ this technique. It is running Android 5.0.0 (Lollipop) or newer, USB debugging is enabled, and it is connected to your development computer via USB.

Run the following in a command prompt:

$ adb -s <device name> reverse tcp:8081 tcp:8081

To find the device name, run the following adb command:

You can now enable Livereloading from the Developer menu. Your app will reload whenever your JavaScript code has changed.

Method 2: Connect via Wi-Fi​

The development server is accessible via WiFi as well. Initially, you’ll need to install the app on your device using a USB cable. After that is complete, follow these instructions to debug wirelessly. Before continuing, you must have the IP address of your development machine.

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 ared screen with an error. This is OK. The following steps will fix that.
  • Open the in-app Developer menu.
  • Go to Dev SettingsDebug 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.
  • You can now enable Live reloading from the Developer menu. Your app will reload whenever your JavaScript code has changed.
