android webdriver with ruby EOFError

[matt]

I've setup the Android SDK and emulator using the following steps:  http://code.google.com/p/selenium/wiki/AndroidDriver 

I'm trying to get android webdriver to work with ruby on a Mac OS X with Mt. Lion.  I do see the WebDriver as an app on the Android Emulator.  When I open it, it says "WebDriver Ready" then that goes away and I'm left with only a title bar at the top that says "WebDriver".

I have setup the AVD with a target of Android 4.2.2 - API Level 17 ran the following command line statements:

./adb -e install -r android-server-2.32.0.apk

./adb forward tcp:4444 tcp:8080

./adb shell am start -a android.intent.action.MAIN -n org.openqa.selenium.android.app/.MainActivity

Here's my ruby snippet I'm attempting:

require 'selenium-webdriver'

browser = Selenium::WebDriver.for(:remote, :desired_capabilities => :android, :url => "http://localhost:4444/wd/hub/")

browser.get "http://www.google.com"

Here's the error log I get in the command window when I run the ruby script:

Here's what I use:

$ adb -s 4df79ff724c2cf75 forward tcp:8080 tcp:8080

require "selenium-webdriver"
require "selenium/client"


include Selenium::WebDriver::DriverExtensions::HasTouchScreen

caps = Selenium::WebDriver::Remote::Capabilities.android(:javascript_enabled => true, :css_selectors_enabled=>true)
client = Selenium::WebDriver::Remote::Http::Default.new
client.timeout = 480
driver = Selenium::WebDriver.for(
  :remote,
  :url => "http://localhost:8080/wd/hub",
  :http_client => client,
  :desired_capabilities => caps)

I don't know if you got an answer to this.

I was having the same issue and solved it by installing the older android-server (android-server-2.21.0.apk).
