How to test on multi devices?

When I test on multi devices. It throws the following error: It looks like the error caused by FlutterDriver using “adb forward”.

[debug] [FlutterDriver] D:\Work\AndroidSDK\platform-tools\adb.exe forward tcp:40477 tcp:40477
[debug] [FlutterDriver] Deleting Flutter Driver session
[debug] [BaseDriver] Event 'newSessionStarted' logged at 1586940481702 (16:48:01 GMT+0800 (GMT+08:00))
[debug] [W3C] Encountered internal error running command: Error: Command failed: D:\Work\AndroidSDK\platform-tools\adb.exe forward tcp:40477 tcp:40477
[debug] [W3C] adb.exe: error: more than one device/emulator

When I comment the following codes, It can run. But can’t test flutter code flutterCapabilities.setCapability (“automationName”, “Flutter”);

@jstephancc this is how I tested it locally:

• clone the repo
• go to the driver folder
• run npm link
• Find out where you appium is installed (this is different for command line and appium desktop, also related how your nodejs is configured. I am using nvm). In my case which appium suggests it is installed ~/.nvm/versions/node/v12.16.2/bin/appium. Based on that I can tell the appium-flutter-driver is in ~/.nvm/versions/node/v12.16.2/lib/node_modules/appium/node_modules/appium-flutter-driver
• run rm -r ~/.nvm/versions/node/v12.16.2/lib/node_modules/appium/node_modules/appium-flutter-driver
• create a symbolic file ln -s <repo path>/driver ~/.nvm/versions/node/v12.16.2/lib/node_modules/appium/node_modules/appium-flutter-driver
• Next time you run the tests, appium should pick up what you have locally.

Hope this helps.

@shibupanda if you will be able to debug this code, please check if this function is called during this issue. It might be a issue, that method is called from appium-base instead of your implementation ?

Please let me know, can i help you somehow ?
