Specify device serial using ADB_DEVICE_ARG (RuntimeError)

I am running a Calabash-android test on CirecleCi. And on running the test I am getting the error response 

It looks like your app is no longer running. 
It could be because of a crash or because your test script shuts it down.
Scenario: Home page and navigate to the registration page
                                                                                             # features/my_first.feature:3
More than one device connected. Specify device serial using   ADB_DEVICE_ARG (RuntimeError)
./features/support/app_installation_hooks.rb:18:in `Before'
App did not start (RuntimeError)
./features/support/app_life_cycle_hooks.rb:5:in `Before'

I install the apk on adb by using the command

  • adb -s emulator-5554 install "pwd/Test.apk"

But even after that getting the above error. Since it is automated I can't go for the calabash-android console command. Is there any alternative to fix the issue. All kind of help is appreciated.

Solution

  • If there is more than one device (or emulator) connected, you need to set an environment variable for ADB_DEVICE_ARG on the machine the code is running on.
