也是用的 ORICO，尝试了 2 级级联 (1 个 Hub 上再连一个 Hub)，稳定性可以接受。

@isotopeX 可以试试通过 node 启动 appium 进程，可以设置内存大小

node --max_old_space_size=2047 /appium安装路径/main.js -p portNum

appium 进程的内存使用达到多少了？

@lucasluo 感谢分享，请问安装过程中的系统弹框有什么好的处理机制不？

多谢多谢。

感谢楼主分享，请教一下 uiautomator2 的 python 库是怎么安装的？

这里说的是闪退，不是 ANR，所以不应该去找 traces 文件；
日志通过 logcat + grep 获取，如果需要更精准的，查看 PID 的变化，定位更精确的闪退位置。

另外一种做法，可能比较慢，HostA 通过 ssh 连接 B 和 C（ssh 配置 token，免登陆）

ssh -q username@HostBIP "/home/test/android-sdk-linux/platform-tools/adb -s udid install TEST.apk"

@seveniruby 感谢你的工具！请教个问题，当某个界面上，uiautomator 获取 dump 文件遇到问题时，appium 会遇到 500 error，此时 appcrawler 会出 exception。
想问一下此时如果想直接 fail 该动作，然后自动 back，再继续，如果要达到这样的效果，我需要怎么配置？

手动使用 uiautomatorview 获取问题页面遇到如下异常，其它页面正常
Error while parsing UI hierarchy XML file: Invalid ui automator hierarchy file.

请教一下，cmd.find('install') 这个是用到哪个第三方工具么？
