React Native run on multiple simultaneous Android emulators

Question

I would like to test my app on at least 2 Android emulators simultaneously. I can start 2 emulators but can't seem to find how to react-native run-android my app on 2 emulators with ADB. If possible I would also like to be able to run a react-native log-android on each one while testing my app.

Is there a way to do so ?

Answer 1

In order to run your react application on multiple emulators, just start 2 emulators as usual and then use the command react-native run-android.

You can even specify any port number as react-native run-android --port 8084 if you want. Your app will start on both the emulators simultaneously. :)

Answer 2

You can only do it on different ports. Because one port, one listener :/
Solve:

react-native start --port 9988
./emulator -port 9988 -avd devicename1

react-native start --port 9999
./emulator -port 9999 -avd devicename2

Edit2:

Before running the emulator, You can write in the terminal and then run it:

function emulator { cd "$(dirname "$(which emulator)")" && ./emulator "$@"; }

First emulator is react .

emulator -port 9988 @react
react-native run-android ( automaticaly detect emulator )

Second emulator is r .

emulator -port 8081 @r
react-native run-android (automaticaly detect emulator )
