请问下：运行以后出现：
raise URLError(err)
urllib2.URLError:
这个哪里出了问题呀，请指教

[debug] [MJSONWP] Bad parameters: BadParametersError: Parameters were incorrect. We wanted {"required":["value"]} and you sent ["text","sessionId","id","value"]
请教下，运行之后报这个错误，不知道什么原因

好帖，好贡献

顶一下好帖···
来一个 nodejs 版本的楼主··

@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？
C:\Python27\Scripts>python C:\Python27\Scripts\android_contact.py Traceback (most recent call last): File "C:\Python27\Scripts\android_contact.py", line 17, in driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps) File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 72, in init self.start_session(desired_capabilities, browser_profile) File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 115, in start_session 'desiredCapabilities': desired_capabilities, File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 164, in execute response = self.command_executor.execute(driver_command, params) File "C:\Python27\lib\site-packages\selenium\webdriver\remote\remote_connection.py", line 347, in execute return self._request(command_info[0], url, body=data) File "C:\Python27\lib\site packages\selenium\webdriver\remote\remote_connection.py", line 429, in _request body = data.decode('utf-8').replace('\x00', '').strip() File "C:\Python27\lib\encodings\utf_8.py", line 16, in decode return codecs.utf_8_decode(input, errors, True) UnicodeDecodeError: 'utf8' codec can't decode byte 0xb4 in position 193: invalid start byte

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()

good

回答 3 楼的问题 ：
desired_caps['version'] = '4.1.2'
真机系统版本要>=4.2...

可行~~已跑上。

@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！

不知道怎么弄了~

根据你的教程做的~

import os
from selenium import webdriver

# Returns abs path relative to this file and not cwd
PATH = lambda p: os.path.abspath(
    os.path.join(os.path.dirname(__file__), p)
)

desired_caps = {}
desired_caps['device'] = 'Android'
desired_caps['browserName'] = ''
desired_caps['version'] = '4.2.2'
desired_caps['app'] = PATH('C:\test\ContactManager.apk')
desired_caps['app-package'] = 'com.example.android.contactmanager'
desired_caps['app-activity'] = '.ContactManager'

driver = webdriver.Remote('http://127.0.0.1:4723/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()

请问楼主，下载 ContactManager.apk 所需要的密码是多少？

加这个群 156413673，群共享有 ContactManager.apk

Parameter 'appPackage' is required for launching application 怎么解决？

#19 楼 @scott

http://testerhome.com/topics/729

可以参考这个。是版本的问题

楼主你好！用代码编译后，textfields[0].send_keys("My Name") 报 index:error，请问怎么解决呀？试过很多方法了，自行解决不了，谢谢
import os
from selenium import webdriver

Returns abs path relative to this file and not cwd

PATH = lambda p: os.path.abspath(
os.path.join(os.path.dirname(file), p)
)

desired_caps = {}
desired_caps['device'] = 'Android'
desired_caps['browserName'] = ''
desired_caps['version'] = '4.2.2'
desired_caps['app'] = PATH('C:\Users\Succi\Desktop\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")
print("debug:",textfields)#input list
textfields[0].send_keys("My Name")
textfields[2].send_keys("someone@somewhere.com")

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

driver.quit()

错误信息：
('debug:', [])
Traceback (most recent call last):
File "android_contact.py", line 24, in
textfields[1].send_keys("My Name")
IndexError: list index out of range

当我用 tag_name 定位输入框的时候：textfields = driver.find_elements_by_tag_name("textfield")
为什么会提示定位错误呢？
错误信息：selenium.common.exceptions.WebDriverException: Message: u'Invalid locator strate gy: tag name‘
用 xpath 定位的时候，出现和楼上仁兄一样的问题，打印出来是空的！

我这边发现问题了，使用 1.0 版本的，会出现上述情况，使用 0.14 版本的，可以用 tag name 定位，奇怪了，1.0 版本的怎么用呢？希望有高手回答下！多谢

二 python+selenium 安装配置：第 2、3、4 步可以简化成下面一步到位
进入https://pypi.python.org/pypi/setuptools/#windows-7-or-graphical-install 直接下载 ez_setup.py 双击运行即可。安装成功后会发现在 Python 目录多了 script 文件夹。然后进入 第 5 步

from selenium import webdriver
from appium import webdriver 两种方式有什么区别吗？

desired_caps['app'] = PATH('C:\Users\Stephen\Desktop\ContactManager.apk')
是必须的吗？

如果不需要安装，直接运行机器里已经安装好的应用，要怎么处理？

二 python+selenium 安装配置 第五步一直不行，求解啊

#27 楼 @lovelorn0327 同问

• -楼主 我已安装 py3，然后按照你的步骤来 cmd 命令 npm 来安装 appium 报错，说不支持 python3....有何解决方案呢...

楼主大大，这个 apk 怎么下载，云盘不能用了。可以给新地址不，谢谢

APK 地址找不到了，能否重新提供一个？新手来混论坛，多多关照！

同样的错误请问怎样解决的？driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps) 这个东西是干嘛的？

@jikunsishen 我也遇到了 selenium.common.exceptions.WebDriverException: Message: u"A new session could not be created. (Original error: Parameter 'appPackage' is required for launching application)"

mark 一下。
