我用 Android 模拟器运行以下命令，它可以工作，我用真正的 Android 设备（测试三星 Galaxy S3 和 HTC Wildfire）尝试它，我得到 EOFError: end of file reached
我正在使用 Windows 7 Professional 64 位
gem list
节目
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)
在其他人中。
我在适用于 Android 4.1.2 的模拟器、真正的三星 Galaxy S3 和真正的 HTC Wildfire S 中运行了以下命令。模拟器正常工作，另外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

我已经尝试过使用用户代理运行的真正完整测试，并且我也尝试在实际的 Android 设备上运行（它也通过了模拟器并在真实设备上出错）但上面是显示的最简单的示例我能找到的错误。
