前言
未加'automationName': 'Uiautomator2'
参数使用Uiautomator可以正常使用driver.keyevent()方法,使用Uiautomator2时driver.keyevent()方法报错:
selenium.common.exceptions.WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: Could not proxy. Proxy error: Could not proxy command to remote server. Original error: 404 - undefined

Uiautomator2
遇到问题
未加'automationName': 'Uiautomator2'
参数使用Uiautomator可以正常使用driver.keyevent()方法,使用Uiautomator2时driver.keyevent()方法报错:
from appium import webdriver
import time
desired_caps = {
"platformName": "Android",
"deviceName": "emulator-5554", # 设备名称
"platformVersion": "5.1.1", # android系统版本号
"appPackage": "com.yipiao", # app包名
"appActivity": "com.yipiao.activity.LaunchActivity", # 启动launch Activity
"noReset": True, # 不清空数据
'automationName': 'Uiautomator2' # toast 必须用Uiautomator2
}
driver = webdriver.Remote("http://127.0.0.1:4723/wd/hub", desired_caps)
time.sleep(10) # 启动时间等待,放长一点
# Uiautomator2使用keyevent事件报错
driver.keyevent(4) # back事件 code 4
调用keyevent方法,执行back事件,对应的code值是4,发现报错

主要原因是Uiautomator2上对keyevent不支持了,用driver.press_keycode()方法可以解决
press_keycode 和keyevent
查看press_keycode 和keyevent 源码,发现这2个方法没啥区别,keyevent上面有个备注Needed for Selendroid,可能是老版本里面的功能。
新版本用Uiautomator2可以使用 press_keycode 方法
# Needed for Selendroid
def keyevent(self, keycode, metastate=None):
"""Sends a keycode to the device. Android only. Possible keycodes can be
found in http://developer.android.com/reference/android/view/KeyEvent.html.
:Args:
- keycode - the keycode to be sent to the device
- metastate - meta information about the keycode being sent
"""
data = {
'keycode': keycode,
}
if metastate is not None:
data['metastate'] = metastate
self.execute(Command.KEY_EVENT, data)
return self
def press_keycode(self, keycode, metastate=None):
"""Sends a keycode to the device. Android only. Possible keycodes can be
found in http://developer.android.com/reference/android/view/KeyEvent.html.
:Args:
- keycode - the keycode to be sent to the device
- metastate - meta information about the keycode being sent
"""
data = {
'keycode': keycode,
}
if metastate is not None:
data['metastate'] = metastate
self.execute(Command.PRESS_KEYCODE, data)
return self
使用 press_keycode 替换 keyevent即可解决问题

driver.press_keycode(4)
keycode相关方法
- driver.press_keycode(4) #发送keycode,功能:按键 Uiautomator2使用keyevent事件报错
- driver.keyevent(4) #发送keycode,功能:按键,与press_keycode无区别 Uiautomator2正常使用
- driver.hide_keyboard() #iOS使用key_name隐藏,安卓不使用参数,功能:隐藏键盘
- driver.long_press_keycode(4) #发送keycode,功能:长按键
