启用“ show_touches”在Android模拟器上通过appium或adb

是否可以通过appium在android上启用 show_touches选项？还是通过adb？

Is it possible to enable the "show_touches" options on android from appium? Or via adb?

我有一个appium测试脚本，该脚本行为不当。我不知道为什么，我想知道它确切地单击了什么地方。

I have a appium test-script, which misbehaves. I have no Idea why, and I want to see where exactly it clicks.
