I'm not sure what selenium client version your environment had, but you might need to follow options style: https://github.com/appium/python-client?tab=readme-ov-file#usage

This is compatibility matrix: https://github.com/appium/python-client?tab=readme-ov-file#compatibility-matrix

AdrianoSandry commented 1 year ago

RYenike Try this:

from appium.options.android import UiAutomator2Options

desired_cap = { "appium:uuid": f"{serial}", "platformName": "Android", "appium:platformVersion" : f"{platform_version}", "appium:deviceName": 'Pixel 4 API 29', "automationName": 'UiAutomator2', "appium:app": f"{apk_Path}" }

options = UiAutomator2Options().load_capabilities(desired_cap) driver = webdriver.Remote("http://localhost:4723/wd/hub", options=options)

Issue is fixed after doing pip install requirements.txt might be selenium n appium were not compatible earlier

Can you share me the solution

Rexze001 commented 1 year ago

@denji-glitch I encountered the same issue, but I have resolved it now. The reason was that the version of the 'appium-python-client' package was not compatible with the version of 'selenium'. This is their version compatibility list:

Estou encontrando o mesmo problema, já instalei as versões compativeis do cliente appium e selenium e não tem jeito.

Consigo usar tranquilamente o appium desktop, mas não consigo conectar o vscode de jeito nenhum.

Please use Options for caps -> https://github.com/appium/python-client?tab=readme-ov-file#quick-migration-guide-from-v2-to-v3 https://github.com/appium/python-client?tab=readme-ov-file#usage We set deprecation warning messages in past client versions to use Options as well, so if you used appium python lib v2.3.0 or later, the deprecation log might be there.

for the inspector, it looks like we need to update

rahulgupta020 commented 1 year ago

In My case I update Appium-Python-Client. So I downgrade the python version. pip install Appium-Python-Client==2.6.0

MauricioJacaraci commented 1 year ago

Estava usando o java 8 e não tava funcionando, depois que atualizei para o mais recente, tudo funcionou.

NaveenKum07 commented 9 months ago

This worked for me this is due to the selenium and python bindings.

dron4ik86 commented 8 months ago

Try this solution

from appium.webdriver.webdriver import AppiumOptions

appium_options = AppiumOptions()
appium_options.load_capabilities(capabilities)
driver = webdriver.Remote(appium_server_url, options=appium_options)
