Appium+Python：踩坑小合集

1、appium 出现报错 “could not connect to server are you sure it’s running?”

如果要用appium去定位元素的话，应该需要去选择Automatic Server一栏

2、启动时碰到的坑

• 解决步骤
  第一步：

driver = Remote(command_executor='http://127.0.0.1:4723/wd/hub',desired_capabilities=desired_cap)   
command_executor的端口号一定要与appium上给你一致；这样就解决一部分的bug了

第二步：
查看一下appium里，哪里运行错误，发现发生了 Android 系统权限错误。然后顺着这个错误，发现启动参数的AppActivity少打了个t，为什么会少打这个t呢！！因为我笔记本键盘的t不好使！！！经常按不下去，我哭了啊！！！

错误提示：error running command: Error: activity and pkg are required to start an application

3、aapt dump badging 软件.apk ，提示aapt不是内部命令解决方式

系统变量的path，把相对路径改为绝对路径即可
