安卓,driver为uiautomator2
通过查看appium server的日志来看整个启动过程
如上图,device api是 19,这是一台安卓4的设备,后续我换成了安卓8的设备,api devel=27
When client request to create a new AndroidDriver session, client passes desired capabilities to the appium node server. Based on the automationName
property in the desired capabilities, appium redirects to the corresponding driver module (by default appium passes to appium-android-driver on the absence of automationName
)
If the automationName
is uiautomator2
then appium redirects to appium-uiautomator2-driver to create the new session.
UIAutomator2 Driver Module: Creates the session , installs the appium uiautomtor2 server apks on the device, starts the server(Netty) and initiates a Netty server session.
UIAutomator2 Server Module: Once Netty server session initiated by driver module, server continues to listen on device for requests and responds accordingly until DELETE SESSION gets invoked.
