我用Android模拟器运行以下内容并且可以工作，我尝试使用真正的Android设备（测试三星Galaxy S3和HTC Wildfire），我得到EOFError：已到达文件末尾
我正在使用 Windows 7 专业版 64 位
gem list
显示
selenium-client (1.2.18)
selenium-webdriver (2.35.1, 2.34.0, 2.33.0, 2.31.0, 2.27.2)
watir (5.0.0 x86-mingw32, 4.0.2 x86-mingw32, 4.0.0 x86-mingw32)
watir-classic (4.0.1, 3.7.0, 3.5.0, 3.2.0)
watir-webdriver (0.6.4, 0.6.2)
等等。
我在Android 4.1.2模拟器，真正的三星Galaxy S3和真正的HTC Wildfire S中运行了以下内容。模拟器工作，其他两个以相同的方式失败。
命令行：
>adb shell am start -a android.intent.action.MAIN -n org.openqa.selenium.android.app/.MainActivity
Starting： Intent { act=android.intent.action.MAIN cmp=org.openqa.selenium.android.app/.主活动 }
>亚行远期 TCP：8090 TCP：8080
然后是红宝石：
require 'selenium/client'
require 'watir-webdriver'
capabilities = Selenium::WebDriver::Remote::Capabilities.android
client = Selenium::WebDriver::Remote::Http::Default.new
driver = Selenium::WebDriver.for(:remote,:url=>'http://localhost:8090/wd/hub',:http_client=>client,:desired_capabilities=>capabilities)
driver.navigate.to('http://www.google.co.uk')
element = driver.find_element(:name, 'q')
然后使用真实设备崩溃

我已经尝试了使用用户代理运行的真实完整测试，并且也尝试在实际的 Android 设备上运行（它也在模拟器中传递并在真实设备上出错），但以上是显示我可以找到的错误的最简单示例。
你没有提到你运行的是哪个版本的安卓服务器。
运行新版本的android服务器（android-server-2.32.0.apk）时，我在模拟器和真实设备上都收到EOF错误，但在不同的时间点。
我通过使用以前版本的android-server（android-server-2.21.0.apk）解决了这个问题。我的测试现在正在运行，没有错误。
