When developing React Native applications, you may often find yourself working with multiple devices or emulators. Running your application on a specific device can be crucial for testing and debugging. This guide will walk you through the process of targeting a specific Android device using the run-android command.
Step-by-Step Guide to Target a Specific Device
1. List Available Devices
First, ensure that your Android development environment is properly set up. You can list all connected devices by running:
adb devicesThis command will return a list of devices attached to your system, along with their unique device IDs.
2. Run the Application on a Specific Device
To target a specific device, use the --deviceId flag with the npx react-native run-android command. Replace DEVICE_ID with the actual ID of the device you want to target:
npx react-native run-android --deviceId=DEVICE_IDThis command will deploy your React Native application to the specified device or emulator.
3. Using Device Selection
If you are unsure of which device to select, you can utilize the --list-devices option to see a list of all available devices, including both connected and disconnected ones. This can be particularly useful in environments with multiple devices.
npx react-native run-android --list-devicesAdditional Tips
- Ensure that your device is properly connected and authorized for USB debugging.
- On some devices, such as Xiaomi, you might need to grant installation permissions directly on the device screen.
- For a comprehensive understanding of using virtual test devices, you can refer to our Virtual Test Devices Documentation.
