Set up the hash differently with

@opts = {appPackage: “com.myapp.demo”, appActivity: “main”, platformName: “Android”, deviceName: “Nexus 7” }  
=\> {:appPackage=\>“com.myapp.demo”, :appActivity=\>“main”, :platformName=\>“Android”, :deviceName=\>“Nexus 7”}

And if I query the hash

@opts[:platformName]  
=\> “Android”

But @appium\_driver = Appium::Driver.new @opts  
RuntimeError: platformName must be set. Not found in options: {:appPackage=\>“com.myapp.demo”, :appActivity=\>“main”, :platformName=\>“Android”, :deviceName=\>“Nexus 7”}
