Appium+Python+UiAutomator2问题，小白求大神解答

在安装UiAutomator2时，执行cnpm install appium-uiautomator2-driver报错。  搞不懂时什么意思，求大神解答，

Appium 1.8.0 反复安装io.appium.uiautomator2.sever 和 io.appium.uiautomator2.sever.test

如题，最近在研究APPIUM，测试安卓8.0的手机，每次运行都要重复安装上面两个东东。 还必须手动点确定，网上没见有解决的啊。急啊

appium连接夜神模拟器adb 5037端口被自己占用问题

appium连接夜神模拟器， 不打开appium时输入adb devices显示有设备连接， 但是打开Python程序运行的时候appium会报错没有连接设备，5037端口被占用，但是查看占用软件就是adb.exe自己，如果关闭这个进程，再次启动adb.exe还是会自己启动，还是一样的问题，不知道哪里出错，求大神解答。感谢！

appium+python进行手机app自动化测试时遇到元素定位问题

使用appium框架进行手机app自动化测试过程中，遇到了xpath定位不到元素的问题。如下图：  我用的定位方法是xpath，如下： device=self.driver.find_element_by_xpath("//*[@id='targetUl']/li[1]/div/div") 可是脚本运行时出错，提示：NoSuchElementException: Message: An element could not be located on the page using the given search parameters. 请问是哪儿出了问题呀，或者用其他什么方式来定位图中选中元素比较好？

appium:求 Failed to launch Appium Settings app的解决办法

我使用的是雷电模拟器 代码如下 ``` from appium import webdriver import time desired_caps ={ 'platformName':'Android', 'udid':'emulator-5554', 'deviceName':'deviceName', 'platformVersion':'5.1.1', 'appPackage':'com.android.contacts', 'appActivity':'.activities.PeopleActivity', 'unicodeKeyboard':True } driver = webdriver.Remote('http://localhost:4723/wd/hub',desired_caps) driver.quit() ``` 请问如何解决 我搜了很久都没有解决, adb devices中有我模拟器的设备

appium运行python脚本时出现 cannot import name webdriver

这是我的代码 from appium import webdriver desired_caps = {} desired_caps['platformName'] = 'Android' desired_caps['platformVersion'] = '5.0.2' #desired_caps['app'] = os.path.abspath('/Users/a58/Downloads/zhuanzhuan_market_923.apk') desired_caps['appPackage'] = 'com.sohu.inputmethod.sogou' desired_caps['appActivity'] = '.com.sohu.inputmethod.sogou.SogouIMELauncher' wd = webdriver.Remote('http://127.0.0.1:4723/wd/hub', desired_caps)

关于appium包名与启动名填写的问题

使用dumpsys命令查询出来的包名与启动名前缀不一致该如何填写到脚本里面  这样填写会报错  求大神解答，感谢

appium报错:Failed to launch Appium Settings app

我的步骤 1.使用adb devices中查看到我的设备(这里我使用的是雷电模拟器) 2.配置完desired caps后运行代码报错 ``` from appium import webdriver import time desired_caps ={ 'platformName':'Android', 'deviceName':'emulator-5554', 'platformVersion':'5.1', 'appPackage':'com.android.contacts', 'appActivity':'.activities.PeopleActivity', } driver = webdriver.Remote('http://localhost:4723/wd/hub',desired_caps) driver.quit() ``` 报错如下: ``` selenium.common.exceptions.WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: Failed to launch Appium Settings app: Condition unmet after 5384 ms. Timing out. ```

python+appium，sendkeys输入不了内容，无论中文还是数字怎么办？

sendkeys其他输入框都能输入，只有这个不能输入，能够定位到输入框，能看得见光标显示了，无论是ID定位还是xpath定位最多也只是显示光标，有过一次手动输入几个字符后成功的输入进去了。贴代码 ``` #输入手机号 account_name = driver.find_element_by_id('com.eestar:id/edtPhone').send_keys("15512341234") #输入验证码 password = driver.find_element_by_id('com.eestar:id/edtCode').send_keys("1111") #点击登录 driver.find_element_by_id("com.eestar:id/txtLogin").click() #点击首页唯一直播 driver.find_element_by_id("com.eestar:id/txtTitle").click() #输入聊天内容 time.sleep(5) #a = 123 driver.find_element_by_id("com.eestar:id/txtChat").send_keys("3369") ```  光标能显示到输入框中，当时最终还是报错，只有这个一个输入框这样，是什么情况呢？ python报错信息： ``` raise exception_class(message, screen, stacktrace) selenium.common.exceptions.NoSuchElementException: Message: UiSelector[INSTANCE=0, RESOURCE_ID=com.eestar:id/txtChat] ``` appium提示信息： ``` [AndroidBootstrap] [BOOTSTRAP LOG] [debug] Attempting to clear using UiObject.clearText().

Java学习的正确打开方式

在博主认为，对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结，前三者博主将淋漓尽致地挥毫于这篇博客文章中，至于总结在于个人，实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍，博客次之，这又是一个层次了，这里暂时不提后面再谈。博主将为各位入门java保驾护航，各位只管冲鸭！！！上天是公平的，只要不辜负时间，时间自然不会辜负你。 何谓学习？博主所理解的学习，它是一个过程，是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。

聊聊C语言和指针的本质

坐着绿皮车上海到杭州，24块钱，很宽敞，在火车上非正式地聊几句。 很多编程语言都以 “没有指针” 作为自己的优势来宣传，然而，对于C语言，指针却是与生俱来的。 那么，什么是指针，为什么大家都想避开指针。 很简单， 指针就是地址，当一个地址作为一个变量存在时，它就被叫做指针，该变量的类型，自然就是指针类型。 指针的作用就是，给出一个指针，取出该指针指向地址处的值。为了理解本质，我们从计算机模型说起...
