测试环境：Appium v1.4.16+android6.0.1
测试代码如下：
#coding=utf-8
from appium import webdriver
desired_caps = {}
desired_caps['platformName'] = 'Android'
desired_caps['platformVersion'] = '6.0'
desired_caps['deviceName'] = '1df0f13d'
desired_caps['appPackage'] = 'com.android.calculator2'
desired_caps['appActivity'] = '.Calculator'
driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
driver.find_element_by_name("1").click()
driver.find_element_by_name("5").click()
driver.find_element_by_name("9").click()
driver.find_element_by_name("delete").click()
driver.find_element_by_name("9").click()
driver.find_element_by_name("5").click()
driver.find_element_by_name("+").click()
driver.find_element_by_name("6").click()
driver.find_element_by_name("=").click()
driver.quit()
测试时可以进入计算器，但是点击就报错了，

来个好人帮忙，谢谢！！
解决方式：更新到新版本，安装了 1.6.4 的 desktop 就可以了。
是不是 activity 不正确的原因呢？.Calculator 貌似我的手机上 activity 就不是这个，也是菜鸟，猜测
嗯，换个 activity 试试
你用的是真机测试吧,你看你手机里的计算器的包名、应用名叫啥，这个脚本写的计算器包名和应用名是安卓原生的，所以一般用来测模拟器是没问题的。你看你的 appium 设置的端口是不是 4723。
获取的设置什么都是对的，我换了个应用也是报这个错，天啊
error: com.android.calculator2/.Calculator never started. Current: com.android.calculator2/.Calculator
有点懵逼。。
@a3096556718 ，试试下面这个，
看报错是
info: [debug] Waiting for pkg "com.android.calculator2" and activity ".Calculator" to be focused
> info: [debug] Getting focused package and activity
提示没有获取到 package 名和 activity 名，试试使用 driver.start_activity('packagename','activityname') 试试
本人新手
@a3096556718 楼主问题解决了吗？之前后端 qa，移动端完全小白，被同样的问题卡一天了，前后 activity 名字一模一样，就是报错，看 logcat 貌似是约 50s 后 activity 才再次变成 I am_focused_activity，不知道是不是这个的原因
哈哈哈 我之前也遇到过 结果是报名前边多了个空格 我把空格去掉就 OK 当时错误提示跟你的提示一样
#9 楼 @boxiangcen 我测试的 app 的 launcher 是一个欢迎页面，启动显示欢迎页面后会进入 home 页面
在有的手机上会出现这样的问题，有的手机上就没有这样的问题。网上查了不少，也还没找到原因
试过指定 appWaitActivity，还是不好用
[debug] Responding to client with error: {"status":33,"value":{"message":"A new session could not be created. (Original error: com.example.test/.ui.FirstActivity never started. Current: com.example.test/.ui.FirstActivity,)","origValue":"com.example.test/.ui.FirstActivity never started. Current: com.example.test/.ui.FirstActivity,"},"sessionId":null}
显示未启动的 Activity 和当前 Activity 是一样的，还报错。。。
@a3096556718 @Pastel @boxiangcen 这个问题解决了吗
此问题和手机有关，换个手机就 ok 了
楼主解决了吗？我也被这个问题困扰好久了。解决了帮下忙。我的 qq865349382
换手机或者更新 Appium 版本可以解决
