我也想知道怎么同时控制两台设备，求高人指点

我也是新手，用的 uiautonator，里面的 id 也会报错，同请教

@young 全部按要求配置完成，运行 android_contact.py 报如下错误，请大侠帮忙看看？谢谢！

@mingyuwang 谢谢这位朋友，已经解决，确实是环境变量没有配置。

python android_contact.py 的代码如下：
import os
from selenium import webdriver
PATH = lambda p: os.path.abspath(
os.path.join(os.path.dirname(file), p)
)

desired_caps = {}
desired_caps['device'] = 'android'#android selendroid
desired_caps['browserName'] = ''
desired_caps['version'] = '4.1.2'
desired_caps['app'] = PATH('D:\test\ContactManager.apk')
desired_caps['app-package'] = 'com.example.android.contactmanager'
desired_caps['app-activity'] = '.ContactManager'
driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)

el = driver.find_element_by_name("Add Contact")
el.click()

textfields = driver.find_elements_by_tag_name("textfield")
textfields[0].send_keys("My Name")
textfields[2].send_keys("someone@somewhere.com")

driver.find_element_by_name("Save").click()
driver.quit()

@young 最后一步运行 CMD,进入 python 目录，输入命令 python android_contact.py 此时会自动安装 apk 并完成相应的添加联系人的操作
我提示报错，请大侠帮忙看看是为何？

@lihuazhang 目录结构：D:\test\appium-0.17.6 里面就是源码文件了。
我采用http://testerhome.com/topics/657 帖子中的方法 appium 安装成功了 ，但是输入 appium-doctor，
提示 C:\Users\cylboy>appium-doctor'appium-doctor' 不是内部或外部命令，也不是可运行的程序或批处理文件。
请大侠看看是啥原因？感谢！

太感谢了，用楼主提供的方法在 windows 下 appium 安装成功。但是输入 appium-doctor，提示
C:\Users\cylboy>appium-doctor'appium-doctor' 不是内部或外部命令，也不是可运行的程序或批处理文件。
请大侠看看是啥原因？感谢！

@lihuazhang step 2. appium-0.17.6 就是下载下来的源码，解压到目录 appium-0.17.6，然后在 cmd 分别运行以下两个命令：
npm config set registry=http://registry.npmjs.org
npm install -g appium-0.17.6
截图就是运行命令后的报错呢

@lihuazhang 下载了也解压了，但是感觉 npm 还是到网上去找 Appium，请教下大侠是为何？

佩服！资料实在是少的可怜，只能在论坛里多翻翻帖子，目前就卡在这了。
