adb - React-Native run-android on specific device

Question

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.
