EOFError:文件结尾已到达Android Ruby Webdriver

我用一个Android模拟器运行了下面的程序，它运行正常，我用一个真正的Android设备（经过测试的三星Galaxy S3和HTC Wildfire）进行了尝试，我得到了 EOFError:已到达文件结尾

我使用的是64位Windows 7 Professional

gem list 

显示

除其他外

我在Android 4.1.2模拟器、真正的三星Galaxy S3和真正的HTC Wildfire S中运行了以下程序。模拟器工作正常，其他两个以同样的方式失败

命令行：

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

开始：Intent{act=android.Intent.action.MAIN cmp=org.openqa.selenium.android.app/.MainActivity}

>adb转发tcp:8090 tcp:8080

然后Ruby：

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')

然后用真正的设备崩溃

我尝试过使用用户代理运行的真实完整测试，也尝试在实际的Android设备上运行（也通过了emulator并在真实设备上出错），但上面的示例是我可以找到的最简单的错误。

您没有提到您正在运行的Android服务器的版本

在运行新版安卓服务器（android-server-2.32.0.apk）时，我在emulator和real设备上都得到了EOF错误，但在不同的点上

我使用以前版本的安卓服务器（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
