Calabash-android with Appium Ruby sign app with custom keystore



I'm trying to sign the app with a custom keystore that I upload
To configure the keystore location, resign and build the .apk file, i have to enter text into the terminal. To do this, I used the following method:

printf ./custom.keystore\nsomePassword\nsomeAlias\n | bundle exec calabash-android setup

This would enter the data I need into the prompts the bundle exec calabash-android setup requires.
This approach results in the following conversion:

printf ./custom.keystorensomePasswordnsomeAliasn | bundle exec calabash-android setup

So it seems the preceding "" has been stripped from the command, rendering it useless.
Apart from this, this command also leaves behind a error:

[DeviceFarm] printf ./internal.keystorenstorePasswordnkeyAliasn | bundle exec calabash-android setup
/home/device-farm/.rvm/gems/ruby-2.4.0/gems/calabash-android-0.9.8/bin/calabash-android-setup.rb:21:in `noecho': Inappropriate ioctl for device (Errno::ENOTTY)
	from /home/device-farm/.rvm/gems/ruby-2.4.0/gems/calabash-android-0.9.8/bin/calabash-android-setup.rb:21:in `ask_for_setting'

	from /home/device-farm/.rvm/gems/ruby-2.4.0/bin/ruby_executable_hooks:24:in `<main>'
Please enter keystore information to use a custom keystore instead of the default
Please enter keystore location
Please enter the password for the keystore

It seems to me I have no option of inserting or interacting with the programs once they have been loaded into the AWS platform.
In case it helps, the test run URL is

I have been trying to get the job done with bash, but it seems it's pretty dificult, even in my local test environment so I think a better option would be using YAML literal style " | " to do the trick. Right now I'm executing a test run to see if it works but I have no previous experience with YAML.
Has anybody been able to overcome this issue?
Thanks in advance!

What device Farm does internally is that , it takes the yaml file and construct a shell script from it.
It then executes this shell scripts as a bash shell script.


You can download the script form the artifacts section of your job.
There would be a file named "Test spec shell script"

printf ./custom.keystore\nsomePassword\nsomeAlias\n | bundle exec calabash-android setup
The reason \n is getting ignored is because bash shell treats \ as a special character. So you need to double escape it (\). However i tried escaping it but it then gets the same error as reported by you
noecho': Inappropriate ioctl for device (Errno::ENOTTY)

SO workaround for this is
What "bundle exec calabash-android setup" does is it creates a ".calabash_settings" file in current directory . So u can create this file in current directory with below content

So u can package the ".calabash_settings" in your test package zip, u dont have to run the above command

important Note

I noticed in your yaml file that you are running the commands

  • printf 'keyPassword\n' | bundle exec calabash-android resign unittest.apk
  • printf 'keyPassword\n' | bundle exec calabash-android build unittest.apk
    As told above, make sure you double escape the \
    So command will become
  • printf 'keyPassword\n' | bundle exec calabash-android resign unittest.apk

  • printf 'keyPassword\n' | bundle exec calabash-android build unittest.apk

Also i noticed that your zip has internal.keystore but the forum post command u pasted above says custom.keystore. make sure you are using the correct name

Let us know if you run into any problems.

I will suggest that you create a local Ruby environment using gemset and replicate the exact command on your local environment which you plan to run inside the yaml file.This will help you debug problems faster

Looks like some of the content in the last post did not properly got rendered. When i said you need to double scape it, replace backslash everywhere with two backslashes
