问题
Is it possible to use the run-android command for one specific device only?
For example, if I have three devices (or emulators) connected and I want to use run-android on only one of them?
Maybe something like adb install -s DEVICE_NUMBER?
Thanks in advance

Elaborating on @alexander 's answer, you can use the following workflow:
cd android
./gradlew assembleDebug # assembleRelease for release builds
adb install -s <yourdevice> app/build/outputs/apk/yourapk.apk # You can check the identifier for your device with adb devices
adb reverse tcp:8081 tcp:8081 Will forward the phone's 8081 port to the computer's 8081, where the packager listens. If you are deploying over Wi-Fi, have a look at: https://facebook.github.io/react-native/docs/running-on-device-android.html#configure-your-app-to-connect-to-the-local-dev-server-via-wi-fi
In a different screen, run:
npm start # Will run the packager
If you really need this, you might want to wrap the first snippet into a script that you can parametrize with your phone's identifier.

To run react-native application on optional device you can specify some flags in run command. To see available add --help:
react-native run-android --help
Then you can specify your device id throught --deviceId
react-native run-android --deviceId=DEVICE_ID
To see available devices ids'
adb devices

In our experience:
To list AVDs:
$ANDROID_HOME/tools/emulator -list-avds
To run a specific emulator: use the -avd flag
$ANDROID_HOME/tools/emulator -avd Pixel_API_28_AOSP
To run React Native in the currently-running emulator:
react-native run-android
To choose between multiple running emulators: (per this answer)
adb devices
react-native run-android --deviceId=DEVICE_ID

May be we can not select which android device attached to run.
Read from official react native website:
You must have only one device connected at a time.
回答5:
You don't need to use run-android command to start it on specific device
Firstly, you have to start the packager:
./packager/packager.sh
Then just build an APK file and run it on target device. APK will connect to the build server, and fetch bundle from it automatically.
But if it didn't happen by some reasons, click on reload button :-)
