[Appium - Ruby] Unable to start driver

[Quyen_Nguyen]

Hi,

I connect a real device but the driver is failed to start.

This is my source code:

require ‘test/unit’
require ‘rubygems’
require ‘appium_lib’

class TestAndroidApp < Test::Unit::TestCase
def setup
desired_caps = {
caps: {
deviceName: ‘Samsung J3’,
udid: ‘42006fd2cc118400’,
platformName: ‘Android’,
platformVersion: ‘5.1.1’,
testName: ‘Android App test with Ruby’,
appPackage: ‘com.sec.android.app.popupcalculator’,
appActivity: ‘com.sec.android.app.popupcalculator.Calculator’
},
appium_lib: {
server_url: ‘http://0.0.0.0:4723/wd/hub’
}
}
$driver = Appium::Driver.new(desired_caps)
$driver.start_driver
end

def test_android_app
puts “Hello world”
end

end

This is the error message:

D:\vs-code-workspace\RubyAppium>ruby test2.rb

I found the problem. It does not work with default host of appium server. I changed the default host then it’s ok.
